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

EX: Crossover Extravaganza!

*Third Person POV*

As Y/n G and Issei laughed together in the hallway, there was a loud boom. Everyone ran out quickly, pulling out weapons and preparing magic. In front of the ORC building, Vali, This world's Ophis, and the Khaos Brigade were waiting.

"Ophis," Y/n G said, "Stay behind me, don't let them see you."

"Yes Master."

Ophis(Devil) hid behind Y/n, as they all stood in front of the new opponents.

"Greetings, Gremorys," Vali said, "It's nice to see you all again."

"What do you want, Vali!?" Issei yelled.

Ophis stepped forward, "We heard that there were some visitors from another dimension, and we wanted to say hello."

Y/n G stepped forward, and stabbed Fell Cyclone in sword form into the ground. He stood tall, and Funus perched on his shoulder.

"I'm not looking for trouble," He said, "But if you strike first, I will retaliate."

"Oh don't worry, we're not going to make the first move," Ophis said, "But, did you really come alone? It doesn't seem like you would."

"I did," Y/n laughed, "If you knew me, you wouldn't really say that's strange."

"I get the feeling." Ophis said.

Gaos appeared on his shoulder, and leaned around him to speak to Funus, whispers going between them.

"Funus," Gaos whispered, "I sense something. This isn't right."

"No kidding," Funus replied, "The first time Ophis and Y/n met in our dimension, they tried to kill each other."

"No, there's someone missing," Gaos finished, "There's supposed to be someone else."

Y/n R, in the back of the group, was speaking to his own Funus. They exchanged whispers back and forth, trying to come to a conclusion.

"Partner, I sense two Gaoses." Funus said.

"Two?" Y/n questioned, "There's only one, the one on Y/n's shoulder. Micheal isn't even here."

"No," Funus said, "He's not... here. He's..."

"Inside." Y/n finished, "Everyone, the book!"

There was a massive explosion, and Micheal Verdain launched out of the ORC building, with Gaos' gauntlet on his arm. He was also carrying the Tomes, and tossed it to Ophis.

"Here you go," He said, "Let's get out of here."

"My book!" Y/n G yelled, "Return it, our your deaths shall be painful!"

Ophis merely laughed, as she opened the book. She read through a few spells, and smirked, putting the book away. She looked at Y/n G, who made Great Red's gauntlet appear on his arm.

"Y/n!" Great Red yelled, "What's going on?!"

"No time to explain!" Y/n replied, "We have to kick some ass!"

Y/n leapt into the air, flying at Ophis, swinging his fist. Ophis caught the first, and Y/n swung with the Boosted Gear on his other fist. It connected with Ophis' face, sending her flying to the ground.

"This isn't good." Ophis(Devil) said.

"Why?" Kiba said, "He seems to be holding his own."

"That's the problem," She replied, "The last time we fought, we destroyed a city, and if Y/n used his entire power, he could've destroyed a continent."

"Divine Dragon: Holy Fist!"

They all looked up, and saw that Y/n's glowing fist smashed into Ophis, sending he flying through the trees.

"Okay," Y/n R said, "Let's get out there!"
