I got isekai (male reader x multiverse)

Beacon Academy part- 1

Y/N *POV*
Finally, this airship is landed after making my life hell. It's looked like Ruby and Yang already left this airship. I also left this devil's airship. I don't know what to say because this school is so big.

Okay, I have to do the most important work in this world. First, I have to find a pure soul girl so she can become my waifu. Second, I have to make somebody my apostle so he can kill me in the future when I become a throne God and my waifu take my place. Final and most important I have to make my legion like Ren or Reinhard, so I gain extra help from them. I see a blonde hair boy who was vomiting.
Y/N: Hey, are you, okay buddy.
Blonde: Yea, I am okay now.

Y/N: By the way, my name is Y/N Heydrich.
Blonde: My name is Jaune Arc! Short, sweet, rolls off the tongue - ladies love it!
Y/N: Of course, they will love it and your last name is a lot similar to a maiden saint.
June: Really? And also your last name is sound like a war soldier.
Y/N: Hehehe... It can be?
Then I hear an explosion but it can be attacked by aliens or an ancient God who was sleeping under this school and now he is awakened. I want to check the place of the explosion.
Y/N: I gonna check the place. You can meet me there, okay.
June: Wait...
But I am already left with my speed because I have 750 souls, so I am using them as my fuel.

When I reached the place, two girls are arguing. I am disappointed there is no ancient God or aliens. Wait a minute, the black hair girl is Ruby, who is this white hair girl and also there is a black-haired girl who is reading a book.
