High School DxD: Chaotic Destruction

{Bonus Chapter for 100 power stones)

"Oh come on, at this rate how would I ever be able to throw an attack if my heartbeat is too much for you all to handle?" I asked while the Knights began to disappear, unable to take more damage. The pawns followed, then the bishops... although Ravel wasn't affected as she clearly had no interest in supporting her brother in this battle. It was like she was only here to watch, so I didn't target her.

"You surrender?" I asked with a smile, walking towards Riser who had recovered from all of the attacks, although it shocked him he was bleeding, his recovery speed was something out of this world. So long as a cell remained, or any part of his body remained, he would always heal.

"I will not surrender to a human!" Riser said angrily, getting up with his body swallowed in his flames. His queen and Rook tried their best to take out phoenix tears to heal, something I saw and ignored.

"Oh? Then let's play a game. If I can get you to admit defeat, I win. But if after 10 minutes I can't. You win." I said with a smile, to which Riser grinned.

"Like hell, I would ever admit defeat to you... but deal." Riser said to which I nodded while bat-like wings grew on my back, proof I was a devil... and a pure one at that, this came out of nowhere. Be it Grayfia who was watching over the match, Rias who was watching the match from Earth along with Asia and the others, everyone was shocked.

"Y-you're a pure-blooded devil?" Riser asked with wide eyes,

"What's so shocking about being a pure-blooded devil? I was born a devil, and taken in by a nun... so you admit defeat?" I asked to which Riser gritted his teeth, but he still refused to admit defeat.

"I will never give up, even if you killed me!" Riser said angrily.

"Let's test that," I said while bringing my finger in front of his face in a snapping motion. Before his confused eyes, I snapped my finger... and his body exploded, his blood, body parts, and inner organs flying all over the place.

"I seem to have snapped too hard... even though I held back. Well, let's bring you back." I said seeing as he was dead. The sight of Riser's death caused everyone to freeze, not believing their eyes. How could a snap of one's finger kill someone?

"[Ingal]" I said while taking Riser's blood, and dropping it to the ground, a magic circle formed before me, and out of that magic circle, Riser appeared, shocked and horrified at the fact he just died.

"Y-you just killed me?" Riser said shaken by the experience known as death.

"So, were your words true, are you going to admit defeat?" I asked with interest, Riser looked at me, and steeling his heart, he glared at me.

"Well, let's see how many deaths it would take. Don't worry, so long as your source remains, I could keep bringing you back within 3 seconds risk-free... this is called the 3-second rule." I said jokingly, but no one found that funny.

"Well, that joke was a hit in the... how do I know that," I said with a frown, realizing that I might be getting some of Anos' old memories back. Back in Anos world, that joke was big, but here... there wasn't even a smile.

"You said you would never give up, even if I killed you. Well, you never thought you would die once in your lifetime right?" I said with a smile.

"I'm a Phenex!" Riser roared, just for me to pause for a moment. I didn't see life and death the same way as others. When I could kill and bring someone back to life, let's say I saw no problems with killing someone over and over again to prove a point... but my sister was watching.

"Well, I was going to just keep snapping my finger, but that will not do as my little sister is watching," I said calmly, Riser although scared, smirked.

"So, I too was born with a unique power," I said while a crimson aura spread from my feet, destroying everything. It was the same aura Rias had, just mine was fully under my control. Everything this aura touched was erased, leading to the sight of the school building just disappearing. There was no sound, a cool side effect, if the aura passed there, what they saw was that the thing that took up that space was no more. This forced us to quickly fly up, while I grabbed Riser and threw him to the ground where I landed in front of him.

"You're of the Bael household?" Riser was shocked, The Bael Clan is one of the remaining 32 Devil clans of the 72 Pillars. It is the highest-ranking clan amongst the 72 Pillars and holds the rank of Great King.

"Oh? I thought that the Gremory held this power seeing as Rias holds it." I asked in interest. 

"Ria's mother is from the Bael clan." Riser explained, using this moment to buy time. I nodded at his words before my aura of destruction gathered. It gathered into my finger, where I tapped Riser's head.

"I just destroyed your willpower... well, not destroyed it, more like damaged it. in a few seconds, you would have a mental breakdown." I said calmly while turning to leave.

"W-what..." Riser paused before his pride began to shatter, the fact he just died, the fact he just faced someone whose heartbeat was enough to defeat him. He was horrified, he let out a horrified scream, quickly admitting defeat to have all of this be over and done with... and so I won...

"... You were a devil this whole time!" Rias cried in joy while jumping into my arms before she glared at me

"I bet you were laughing this whole time." She said, feeling embarrassed that she thought being a devil would have pushed me away when in truth I was a devil the whole time.

"I kinda found it funny. What were the chances we held the power of destruction and were pure-blooded devils." I said with a smile, this all seemed fated to happen or something like that.

"Congratulations." Issei joined with everyone else, said with a smile, I nodded towards them before I got going. I was late for work.

"You can skip work for one day... let's go.," RIas said while casting a spell, and teleporting us away back to my room.

"Let's do it," Rias said while hugging me, well I didn't need to know what she meant by let's do it. She was talking about sex.

"I don't want us to lose our first time thanks to you feeling like you need to repay me," I said with a smile.

"But I made my mind up about this weeks ago, no matter what happened, after everything was done... I wish to give you my all. I love you, that's something I'm sure of with all my heart... and I know you love me. Fuck taking it slow," Rias said to which I smiled lightly, how could I say no after she said that?
