THIRD POV—
The whole Underworld was covered with Ravel's mana. For the residents of that plane, there was no difference left between oxygen and her mana. Their body now not only had oxygen but also, had mana in them. Ravel's mana was running through their veins.
She said, "See, the whole... I mean, the whole Underworld is now breathing my mana. You as well, my brother. Let me show you the final form of my flames, that has surpassed beyond everything." The space around her body started to become blurry and heavy. The ground started to crack. The temperature was gradually rising up. Leaves ignited and water bodies were evaporating at a very fast rate. Everyone was sweating profusely from the heat's impact. Their lips were drying up, and so did their mouths. But the person, who was heavily affected by that phenomenon was Riser. He was scratching his skin. He was feeling as if his skin would melt.
Ravel continued her explanation. She said, "You can't see these flames of mine. But you can see the distortions around my flames, like they are trying rip apart the very fabric of space. Then again, you can feel it. These flames are very destructive. I use it very carefully. Just a small amount is sufficient. The only way you can survive these flames if I, don't take you or my opponent seriously. Yet, I haven't fully completed demonstrating these flames power. While I could show you more, but I think this would suffice."
[Spectator Section—
All the devil kings couldn't believe their ears. Even Sirzechs was shocked. He knew she was hiding her strength, but what happened in front of his eyes, was hard to swallow.
Falbium started, "We are breathing her mana—"
"— that means she could have access to our body," completed Ajuka.
Zekram was clenching the handle of his stick. He knew what Ravel just did now, was to show him and everyone that she couldn't be forced to do anything. She would do what she wants. If she wanted to rest, she would and if, she wanted to fight, she would. That power demonstration was a way to establish her superiority.
Tsubaki asked, "Captain, I can't believe that she is this powerful."
Sona sighed, "Yeah. You see, Ravel is someone who takes things lightly but when, someone angers her... they would face dire consequences. She knows that she doesn't need to do anything. She is basically a royalty. Even if she doesn't do anything, her parents and elder brothers expect, that bastard, can take care of her. She is someone who would want her lover to take care of her, not the other way around. So, all she does is lazing around idly and enjoying her life. No one expects anything from her, and she knows that. The only thing she hates is being ordered or told around. She doesn't want anyone to order her unless, she likes it." She expected Ravel to take revenge from Rias, like she did with her but in another way.
Kiba swallowed loudly and said, "Leader... did we really act up against someone of this calibre?"
Koneko shuddered at the feeling of Ravel's mana in her body. She stuttered, "T-this f-f-feels l-like I-I am b-being s-slowly suffocated..." She wasn't able to complete her sentence as she soon lost consciousness.
"Koneko!!!"
Her friends yelled in unison.]
Ravel retracted back her mana. As soon as she retracted the mana back, everyone took a sigh of relief.
After scratching himself for almost five minutes, Riser finally stopped scratching himself. He looked at Ravel and saw her looking at him like he was some of piece of shit. As the saying goes— 'Anger always clouds your judgement.' That was what happened with Riser. Infuriated, Riser covered his arms with his fire and tried to hit Ravel.
Ravel clicked her tongue at his weak attempt. She didn't even block his attack. She just blocked his punch and torn his arms apart.
"AHHHH!!!!!"
Riser screamed in pain. Ravel said, "It's time to end the fight." His arms regenerated itself, thanks to the power of Phenex bloodline. Hearing her words, he started to cackle like a madman. He said, "But how? Just like you, I can regenerate my body parts like nothing. You can't defeat me."
Ravel nodded her head in acceptance. She said, "Yes, that's true," she smirked, "my attempts would be useless. But what about the pain? I will cut you as many times as possible. You do feel it? The pain, right? Nah, you will."
Ravel's words confused Riser. Just as he was about to come up with a retort, Ravel released her claws and pierced his throat.
Blood gurgled from his mouth, as he tried to scream. Ravel looked at him and shook her head in fake pity. She said, "My adamantium claws have pierced your voice box. You can't scream. You will just feel pain, and pain, and pain, only pain. Look, it wouldn't have happened if you didn't say those words to me. I mean, how fucked up can a person be to say this to his own sister? Yet, you are in front of me. 'You will join my harem.' Isn't that what your filthy mouth said? If any other person said this to me, I would have been less... violent. But you said these words to me, my dear brother. 'Consequences,' is the only word that I want to describe your situation with."
She released her left hand's claws and started to transfix him repeatedly with her claws. Riser wanted to scream, shout, plead to her, but he couldn't. Her face was covered with his blood; the blood which was of her own brother but, there was no shred of mercy in her eyes.
After stabbing him to her heart's content, she looked at his state. He was battered, crying in pain, and was bloody.
Ravel brought her mouth to his ears. She whispered, "Mother and Father loves me. The same goes for my brothers, except you. No one in our family would raise fingers at me. They will only hold you guilty, for forcing their darling daughter/sister to raise her hands... brutalize, would be the right word, I guess... yeah, where I was? Yes, brutalize you. Riser, you are not loved even in our family. Not only you are unloved but also, you are weak. You are feeble. Your arrogance has no limits. You are a dog, which bites only the weaker than him. If someone stronger stands in front of you, your behaviour is similar to that of a mouse. I will say this once. Give up, while you can."
Riser fell to the ground as Ravel retracted both of her claws. Just before losing consciousness, he uttered, "I give up."
"THE WINNER OF THE MATCH IS RAVEL PHENEX."
