What do you do if you accidentally transmigrate?
Wait, your world doesn't have magic?
Then doesn't that make me invincible? I'm the disciple of a universe-class archmage!
What, wait, your world doesn't have superpowered people?
Holy crap, I'm freaking invincible! I'm an unprecedented super-type esper, one in ten thousand years!
Whoa, hold on, hold on. Your world hasn't even left Earth yet?
Hahahaha, I'm invincible! I'm the founder of the Super Galactic Fleet!
Don't hold me back! I'm not crazy! I really am invincible! I really am!
