I transmigrated as a Cheat Book!

... Long story short, I'm a book that can grant those powers to people I deem worthy.

Because of me, a supposedly rom-com world became a bit... colorful.

"My Grandma used to say that- I'm a man destined for something bigger, the ruler of all, the man who walks the path of heaven! Henshin!!" (Hikigaya Hachiman)

"There is only one reason why you lost. One simple reason... You pissed me off!" (Shirogane Miyuki)

"My right hand... it's burning! O' Flames, render all creation in the universe to ashes... Ryujinjakka!!" (Togashi Yuuta)

... See? Really colorful, right?

(This is a Comprehensive World, where every rom-com anime overlaps)
