Synopsis
"It's useless to think about the truth of the world, the meaning of what I was born with, and so on."

Kei Morimoto, a college student who was just trying to spend the "remaining life after the age of 20" in peace. But one day his life suddenly changes. A painting that governs the wisdom of the world, the thoughts of alchemists who lived 400 years ago, and the beautiful goddess of wisdom. Kei's daily life is full of incomprehensible events, and eventually Kei himself becomes involved in a historical event involving the alteration of historical facts.

This is a new boy meets girl story that transcends time and space.
