Death Rides on Swift Wings: a RWBY x Male Reader x Highschool DxD Story

EX: Crossover Extravaganza!

*Momo POV*

I searched through the strange book I stole from that guy who attacked us. The entire book seemed to be written in Greek, and I had a translator open on my phone.

But my mind was elsewhere. Who was that guy? Where did he come from? Why is he here? Where is he now? What is this book? Is he coming?

But I got stuck on one question.

{Flashback}

"I'm sorry," He said, "It shouldn't have come to this."

{Flashback Over}

Did he mean that?

He sounded legitimately regretful about what he did. As if, he didn't really want to do anything to us.

"Maybe..."

"Maybe what?"

I looked up, seeing Izuku standing above me.

"I was just thinking," I said, "Maybe if we had just given him the book, nobody would have gotten hurt. If I had just... not ran away."

"Momo, don't say that," Izuku said, "Y/n would have fought, no matter happened. That guy was too far to work with."

"Yeah," I agreed, "I just can't help but think that something else could've been done."

"Perhaps," He said, "Come on, Y/n is starting to wake up."

I stood up, grabbing the book, as we walked into the hospital room where Y/n was staying. Apparently whoever that guy was heavily damaged Y/n's spine. Recovery Girl managed to fix a lot of the major damage, but Y/n still had a few injuries.

We walked into the room, seeing Joey sitting next to Y/n's bed. I walked next to him and took a seat, grabbing Y/n's hand.

"H-hey Momo," Y/n said weakly, "Did we get him?"

"Not really," I answered, "But I did get his book."

"That's good," He took a deep breath, "Oh man, I'm tired."

He laid his head back down in the pillow, and let out a chuckle.

"You know, I felt something when I fought him," He spoke, "A sense of... brotherhood."

"Brotherhood?" Izuku asked, "What's that supposed to mean?"

"I don't quite know myself, but it felt as though we have something in common. Much more than just a love of fighting."

"Y/n, go back to sleep," Joey said, "You're talking crazy."

An evil laugh came from the shadows of the room.

"Not completely crazy," A voice said, "At least, not if you know the whole story."

We all turned to the corner of the room, where a set of red and gold eyes were glowing. The guy who attacked us walked out of the shadows, followed by Evil Y/n. They both stood there, and the guy who attacked us held out his hand.

"My spellbook."

I held it out to him, and he grabbed it, "There! Go!"

The book began to float, opening its own pages. It flipped to about halfway through the book, and he read the page.

"This is my spellbook," He said, "Let's go."

"Not quite yet, Y/n," Evil Y/n said, "You have to hold up your end of the bargain."

"And what do you want me to do?" The guy who attacked us glared.

Evil grabbed his arm, and then grabbed Y/n, who couldn't fight back.

"Lord Darkness, bring us to you."

There was a flash of... darkness? And they were gone.

"Y/n?!" I yelled, "Y/N!"
