Blurb: As the sun disappeared, ghosts ran rampant and evil gods descended. They were deities forced to fall into depravity by malicious thoughts, and they came to destroy humanity. Fortunately, humans also awakened extraordinary powers. After a long struggle, the one hailed as the Savior sealed the world within their own ability, holding back the evil gods.
At the moment of their ascension, they discovered that the evil gods had escaped to another world!
What could they do? As the Savior, of course they had to negotiate with that world's consciousness and pitifully work overtime. But ascension had taken their name away, so they put on a secret identity.
Sequence 0, The Fool, Dazai Osamu: I hate dogs so much! Why is my companion a dog?! Akutagawa-sensei... no, Tan, help me!
The secret identities can be treated as independent characters.
