"I'm dead."
When he opened his eyes, Ren Tongzono found that he was still alive, sitting on the train that was supposed to carry him to the end of his life. But the passengers in the same car disappeared without a trace as if they were erased with an eraser. This is just the beginning of bizarre events. He soon learns a truth that subverts his cognition: the Maisaka City where he lives, and the entire world, are actually the "Hakoba" created unconsciously by his cowardly and inconspicuous classmate at the front desk - Kirishima Aoi.
Kirishima is a god in this world, but he has no idea of his own power. Her emotional fluctuations turned into a raging flame giant in the "Incinerator", while Long Youren, a popular figure in the class who called himself "The Awakener", transformed into a knight to clean up. What's even more bizarre is that Ren became the only special being who could see Kirishima's emotional color "Buddha's Light", and was inexplicably "selected" by her. When Kirishima nervously suggested going to Ren's house to watch the movie "Weeping Angels" over the weekend, Ren found himself in a deep whirlpool.
The class teacher Shikuji Ren, who claims to be the savior, warns him that Kirishima is a disaster that destroys the world, and she must be "happy" to save everything; the robot Hikari Seina, who claims to be an observation terminal and comes from the "main world", implies that Ren is the key catalyst; and the Awakened Organization represented by Long Youren regards Kirishima as a god that must be protected. The three forces have their own purposes and push Ren to Kirishima's side.
An ordinary classmate's home visit, behind the scenes is the existential crisis of the world of Hakoba. Why did the introverted god girl choose him alone? Does her melancholy point to the abyss of despair as speculated?
