Chapter 51 - Demon vs Siren & Enki

"Rimuru, I love you."

Those words left Velgrynd's mouth, it was words that Rimuru knew was coming.

Rimuru placed his right hand to her cheek, "Velgrynd, I-"

"I know," Velgrynd had a forced smile. "Big sister told me, it's fine if you don't reciprocate my feelings. I just, I think I just wanted to tell you how I really feel."

She knew, she knew that for someone like Rimuru who is a demon. A being that mainly lives for chaos and fighting, would have a hard time comprehending love.

And yet she hoped, that in some way, maybe her feelings will reach him.

Of course, that was only wishful thinking in her part. She felt scared of what Rimuru will say to her.

Will he accept her love? Or will he brush it off? The anticipation was painful that when Rimuru spoke, Velgrynd interrupted him.

Scared that what comes out of his mouth is painful rejection.

Velgrynd felt a tear fell from her eyes.

Ah, am I crying?

"That's not what I meant," Rimuru wiped the tear off,

Rimuru felt pained seeing her expression. He knew, he felt something for someone like her.

Of course, why wouldn't he? It's no exaggeration that Velgrynd is one of the most beautiful women that Rimuru has met in his thousand years of living.

Not only that, for a demon's perspective being strong is also an appealing factor.

However, that wasn't what attracted him to her, no it was not. Not the strength nor the beauty.

It was their little everyday interaction that let feelings bloom from Rimuru's demon heart.

The adorable Velgrynd who loves to chat with him. The cool and serious Velgrynd that appears whenever something is happening. Even the relax Velgrynd when she is just loitering in his office reading her favorite novels giggling every so often.

Those are the factors that attracted Rimuru to the Scorch Dragon named Velgrynd.

It took him a while to notice these feelings, and he had felt from others to realize it.

And when he understood it, he remained passive and dense.

He was scared, love and romance were foreign not only for him, but for his entire race.

Granted demons may come to respect others, but it's not similar enough to make a comparison.

That's why he ignored the signs, that's why he waited for her to make a move.

And he promised that when she does, he'll reciprocate it by admitting to the feelings that he's kept bottled up.

"I do feel something for you, I just want to make sure that you'll feel the same. Especially since I'm still knew to this whole feeling, if you want to stay the same I'm fine with that. If you want to take it a step further I'm fine with that as well."

"Then.." Velgrynd looked at Rimuru's eyes in disbelief and surprise.

Her heart beating loudly from the joy it was about to bring.

"If you'll take me, I don't mind being with you. I love you too, Velgrynd."

He gave her a genuine sweet smile.

Velgrynd couldn't hold her feelings, earlier she was barely holding on expecting a painful rejection. Now she was experiencing joy never felt before in her life.

She cupped both his cheeks with her hand, and leaned in for a kiss.

The kiss lasted only a few seconds, but for the two, it almost felt like forever. Yet, it had to end.

Velgrynd pulled back a few centimeters, their faces still close to each other that their breaths hit each other's skin.

"Of course! I really love you Rimuru!" Velgrynd smiled.

The two kissed once again and enjoyed the moment with just the two of them.

Nothing matters in that moment but the two of them, and their feelings for each other.

That is how Velgrynd's and Rimuru's relationship official started as Lovers.

The next day,

The two went to the empty world, where the they trained, to meet up with Enki and Siren.

""Rimuru-sama!""

The two former spirits kneeled down in front of their master, it has been more than 500 years since they last saw each other.

The two are emotional for the reunion that they are participating.

Basking in Rimuru's presence, feeling satisfied even if they died today for some unknown reason.

"How has your training been going?" Rimuru got straight to the point of his visitation.

Enki and Siren both stood up.

"We have become stronger than we ever were before!" Enki announced with a thump to his chest.

"Our proficiency with our elements have also increased in an unprecedented level." Siren added to Enki's remark.

Rimuru looked towards Rain and Velzard who were here with the request of Rimuru to confirm their statements.

Rain and Velzard both nodded their heads.

Velgrynd who joined the two also confirmed their words.

After a few pleasantries of the two True Dragon Sisters, they left.

"We're going to have a chat, see you later!" Velzard smiled as she dragged the blushing Scorch Dragon away.

"Good, let's test it shall we." Rimuru opened two gates from beside him.

"They are.."

"Ah, Lilith made them," Rimuru said matter of factly. "Wait you don't know her, do you? Well no matter." He shrugged

Hundreds of Insectoids with mechanical bodies started coming out of the gate.

"Critters, eliminate them." Rimuru pointed to Enki and Siren.

The Critters followed the order and, all of them started attacking the two.

"WA-wait Rimuru-sama! Are we allowed to destroy them?" Enki dodged as he asked.

"Yeah, I give you permission." Rimuru grinned.

Enki smiled, after which the area around him burned in a spherical shape reaching a few meters.

Four Critters destroyed with some melted while others turned to ashes.

"We will show you how strong we've become Rimuru-sama!" Siren flew above, with the Critters following her.

"Frozen mist,"

The sky started being covered in very thick mist, Siren went to the middle of it.

The Critters followed suit firing artillery as they do, once they started going deeper inside the mist, they noticed their bodies malfunctioning.

A few parts of their bodies started to freeze, and the ice continues to crawl it's way to their entire body. Their flight mechanisms have started to malfunction. 

Having more than half of their body covered in ice, and their means of flight immobilized, several Critters started to fall to the ground.

Once no Critters were inside the mist, it started twirling to the middle.

Siren with her hand raised continues to absorb the mist to her palm. Until eventually an arrow made of mist materialized.

She took out her knew weapon, a bow made by Guran 'Crescent' . She placed the mist arrow and pulled the string.

Aiming at the middle where Enki was currently fighting with his weapon.

"Frost Bites," she let go of the string and the arrow flew down towards the ground.

Half way there, the arrow split into tens of small arrow mist. All of which took a different direction going down.

The arrows each hit a different Critter, the Critter in question immediately turned into a frozen statue. It didn't even have time to process what happened.

What's worse, they can't escape being frozen. Their bodies are completely made of ice, meaning if they tried to move, their bodies will shatter.

And if they don't, they'll die of the cold temperature they are experiencing.

"Hey!" Enki swung his Axe 'Inferno' to one of the arrows, "That was aimed at me!"

The arrow quickly disappeared from contact, Enki rushed to the rest of the Critters who were not targeted and started finishing them off. The Critter wielded a variety of weapons from melee to large cannons for arms.

Each swing of Enki's new axe were all fatal hits. As the Axe absorbs Enki's magicules to produce intense heat inside the whole weapon.

Getting hit by such a weapon guarantees instant cremation to weak enemies.

The Critters that were hit by the swings either had their limbs melted by the heat, or died from the flames that remained.

"Erupt!"

With a swing of his axe, a large Shockwave with heat reaching the thousand degrees hit the cluttered Critters.

The surrounding areas ground was blasted, and the Critters' bodies flew and burned to ashes in a few seconds.

"Hoh your tougher than the rest," Enki grinned looking at one of the Beetle type Critter. 

It had large blades for arms and a cannon in its horn. It screech as it rushes to Enki. The two traded blows for several seconds before Enki had the upper hand after managing to cut off one of its blades. 

"If only the quality of your sword was higher, it would have been more fun." Enki showed a victorious grin to the burning corpse of the beetle. 

"Those were unique grade blades you know," Rimuru shouted from a far. 

After a few minutes all of the Critters were dead.

Some are turned into Ice statues while others where either melted corpses or burnt ashes.

Rimuru clapped his hands, "How about this ones,"

Rimuru grinned as he ordered two beings to show up.

"You two have gotten stronger!" Enki said.

"Did you evolve?" Siren asked as she noticed the difference.

Diablo and Testarossa stepped out of the gate, preparing themselves to fight the two former spirits.

"This two will be your opponent," Rimuru gestured to the two Primordial demons. "If I like what I see, you'll get a reward from me."

And with that as a starter, the two demons rushed in.

Diablo took out his claw like gauntlets and aimed it at Enki, who parried it using his axe.

"Kufufufu impressive," Diablo stated as he readied for a slash.

Before he could, Enki swung his Axe with both hands towards Diablo's stomach.

"Eruption!"

Diablo dodged and took some distance before the attack manage to connect.

"Kufufufu what destructive power, that weapon is surely legendary grade."

Diablo complimented as he readied himself to attack again.

Meanwhile,

"Oh my," Testarossa was being surrounded by five pillars of ice.

"Frozen seal: Pentagon (Five pillar prison)!"

Siren who was flying in the sky, watched as she activated her magic.

The ice pillars started to connect with each other. Forming a type of film that covers all sides of the pillars like a wall.

"Hope that at least last a few minutes." Siren muttered as she readied her bow.

"Oh," A voice uttered behind Siren. "That is quite a complex magic."

Siren turned to see Testarossa, with her right hand below her chin in a quizzical gesture analyzing the Magic Siren just used.

"Wha!" Siren flew away trying to gain some distance. "Frost bites!" She fired.

"That magic would have been a pain to escape, maybe a minute or two." Testarossa dodged the arrows and flew chasing Siren.

"The flaw is that it takes too long to activate, I had a few seconds of leeway." Testarossa preach as she caught up with Siren.

"Is that so? Thanks for the input!" 

"Though props for making that," Testarossa activates several magic circles around her. "Let's see you escape this barrage."

Several nuclear cannon were fired towards Siren.

She block and dodge a few of the attacks, while also firing at Testarossa with her Bow.

"Mist," Siren started creating mist around her again, similar to before.

"I won't let you," Testarossa rushed in and created a large nuclear cannon.

The attack dodged all the arrows coming towards it and hit Siren directly in the head. Blowing the head away from the body.

"An illusion," Testarossa muttered seeing Siren disappeared into the mist.

"Don't underestimate me too much," Siren's voice echoed from the mist.

Testarossa sense an incoming attack and took a stance.

From inside the mist, a barrage of arrows started coming in the hundreds.

A large explosion appeared on the ground as the fight in the sky continues.

"Kufufufu let's take this up a notch," Diablo appeared behind, he manage to pierce Enki's back.

"Ghak!" Enki turned with a swing of his Axe, Diablo was not there anymore.

Enki swing his Axe to his shoulder with one hand, and grabbed the handle with both arms.

"Yes, let's do that!"

Enki rushed towards Diablo, with his Axe the center of it started to glow red.

Using the Axe as catalyst for his attack.

"Pyro Art!" Enki swung his axe downwards to the ground, "Axe of Blazing Ember awaken from your slumber: Erta Ale!"

The surrounding terrain turned into molten lava, with the temperature reaching the thousands of degrees. The ground started to melt, slowly sinking the area around them. 

"Kufufufu an attack that affects a certain range of the area." Diablo looked at the lava flowing below him as he floated above it. The boiling lava, formed a bubble and exploded into a small geyser and it hit Diablo. 

"Hm?" Diablo noticed that he felt some damage, while minor it did mean that the area has the ability to injure him. "Kufufufu and this is them without a name," He looked up seeing Testarossa firing at the mist cloud where Siren is hiding. 

"Won't you be in a disadvantage with the terrain below?" Testarossa asked as she looked below, the heat rising up enough to reach the two. Not that they actually felt the heat, but she believes this may hinder Siren's attacks.

"That is half-right," The mist started to turn and become a tornado. "While it is overall disadvantageous for me, it doesn't mean I can't take advantage of it." 

Testarossa noticed the steam and smoke from below are being absorb by the tornado. The tornado turned and disappeared to Siren's hand once again. Manifesting an arrow made of steam. 

"Monsoon Turbulence!" The arrow fired at Testarossa turned into a cyclone midway bringing with it heavy rain and strong winds. Pushing Testarossa several kilometers away. 

"That was some wind, If I wasn't evolved that would have been fatal." She complimented, her appearance showing small bruises, as Siren arrived with an arrow readied to her bow. "You two have really improved yourselves."

"Thanks," Siren smiled. "I'm not done yet though," Siren released the arrow above her. 

"Cryo Art: Bow of all that is arctic, freeze the realm into glacial epoch: Yakutsk Snowdome!" 

The arrow exploded above, it then started forming a type of spherical globe in the surrounding two kilometers. A large ice barrier that freezes all that is inside it is now formed.

"Hmm," Testarossa looked around the art, "This looks just like a snow globe that I saw in one of my worlds." She opened her palm and a snowflake dropped in the middle. 

"What a beautiful art~" Then Testarossa noticed her palm started to show freezing. "Hm? My statement remains correct." 

Testarossa heated her palm to melt the ice. Then it returned, several snowflakes started hitting her body as well. Slowly covering her body with ice. 

"Well this isn't good.." Testarossa muttered to herself as she slowly freezes.

"Well this isn't good" Diablo said as he tries to escape Erta Ale. 

Erta Ale is a terrain attack that not only change the terrain but the user has full control of the environment. Right now, below Diablo are several geysers made of lava. If only that was all, instead of after exploding upwards they would just fall. Instead they are like snakes that pop their heads up and rushed at the enemy. 

"Nuclear cannon." Diablo fired at a few of the Lava geyser snakes that have been trying to capture him. "Kufufufu even as a demon peer, he's still giving me some trouble." 

A large geyser erupted a couple of meters infront of Diablo. From behind the geyser, Enki came out and rushed with his axe. 

"Destructive Eruption!" Enki swung down at Diablo with full force. 

From below Diablo, the geysers finally manage to coil itself to his feet. Reaching his waist immobilizing him for a few seconds.

Diablo noticing the danger, concluded what he needed to do. 

He used his right arm to block the attack and with his other hand removed the lava coiling him. 

"Kufufufu that really is a dangerous weapon," Diablo said after taking some distance, his right arm burnt that only some flesh and the bones are left.

"Kufufufu if it was someone else I would have massacred you already." Diablo explained, noting the fact that Enki damaged the body that Rimuru gave him. 

"Haha! same here," Enki pointed to his injuries. " Let's continue shall we," He brandished his axe as it glows rushing to Diablo.

"Surrender now, otherwise you'll be frozen." Siren looked at Testarossa who was halfway frozen, the ice covering a fraction of her face and reaching to her waist. 

"Fufu I still have a trump card." Testarossa looked at Siren with a smile, a small black flame appeared in front of her. The heat from it managed to melt the ice covering Testarossa's body. 

She check her body before stretching her right arm forward with the black flame in front of her palm. 

"Nuclear flame!" 

The black flame started to grow in size, with no signs showing of it stopping. With the heat that it is spreading, the surrounding ice and the snowdome started to melt and fall apart. 

"Tch," Siren looked around and finds herself to close to the blast radius of the attack.  

"Cryo Magic: Cocytus" Siren tried to freeze the ever growing thermonuclear explosion.

The bad news of the matter is she couldn't counter the nucleur flame enough. The good news though is that with the help of cocytus, she manage to escape almost completely unscathed aside from minor burns.

"You manage to escape?" Testarossa spoke seeing Siren away from the large explosion. 

"Not only that," Siren said as she raised her hand above her. "It's still not perfect but, Relentless Cyclone!" 

Soon dark clouds started to gather above Testarossa and Siren. Several tornandos came down from the clouds, bringing with it heavy rain. The rain drops fell like bullets, and the wind sharp enough to slice through several people. 

Four tornados cornered Testarossa in between them, the moment she tries to pass through is the moment all of them attack her relentlessly. 

From the swirling tornado, tendrils in the hundreds started to rush to Testarossa. Trying to grab and capture her. 

Testarossa evokes a variety of magic to destroy the incoming tendrils.  "Huh, am I cornered?" 

The battles continues on for a couple of more minutes before Rimuru finally announced the end of the battle. 

"From what I could see, I don't think I even need to ask the two." Rimuru started, "But for formalities sake, Diablo and Testarossa what is your verdict?"

"Kufufufu Rimuru-sama, Enki has shown his abilities and the potential that can still be unlock. My verdict is he is worthy."

"I as well, feel the same for Siren, their Arts whether it be Pyro and Cryo, have shown and opened new paths for new abilities of their respective elements."

Rimuru nodded as he listened to their comments. 

"Enki, Siren."

""Yes!"" The two stood up, facing Rimuru with a serious expression. 

Meanwhile, Rimuru has a more relaxed expression on his face. "You two have worked hard, improve yourselves more to be able to land a blow to them."

Rimuru reminded them of the reason for their training, the defeat of the Primordial/Great spirit of Fire and Water. 

"Of course Rimuru-sama!"

"We will make sure of it!"

"Good, from here on out. You will be Agni," Rimuru pointed at Enki. "And you will be Runa." He gestures to Siren next. 

"Live up to the names I have given you two and grow much more stronger!"

""YES!""

A/N: Finally over... 

NGL it's fun creating new abilities for Original characters, heck even to tensura characters. Just a bit of research and imagination can make some unique and fun abilities. Just research some mythology and you get Ultimate skills lol.  

So technically 

Demon Peer(S-minus) = Enki and Siren (S-minus) of course in terms of skills and proficiency someone is better than the other. Diablo would have won with Paradise world however that was banned by Rimuru since it wouldn't be a fight. They needed to see the extent of their powers after all. 

now that they are named, Agni and Runa are (S-rank)

You know what, I'll place the ranks of everyone here. 

B-plus to A-minus = Fiery men, Water Sprites

A to A-plus = Cherufe, Aqua Sprites, 1st gen Vega Critters 

Special A = enkis, sirens, Apollyon, Mitzrael, 4th gen Vega Critters 

S-minus = Enki, Siren, Gamaliel, Yael, Apito, Zegion, Demon Peer, Jahil, Luminas, Sylvia

S-rank = Agni, Runa, Ein

S-plus= Rimuru, Lait, Velgrynd, Guy, Zelanus, Velzard

Special S= Veldanava
