Hong Yu, a Herrscher of Rules created by the Imaginary Tree itself, nevertheless stands on humanity's side. After being sealed by the Imaginary Tree and cast away into another world, Hong Yu discovers that unlocking any one of his powers causes unnecessary destruction to his body. Oh, well! Let's kick Honkai's butt! Go!
After losing most of his memories, he is caught in a cycle of reincarnation and just wants to give up and laze around. Then a certain quiz space appears and disrupts his life.
Quiz Space: Hey, kiddo, here's something you should know: you're not Kiana.
Kiana: Huh?! Are you kidding me?!
Quiz Space: Hey, kiddo, here's something you should know: you used to have white hair.
Bianka: What do you know?
Otto: Someone from 500 years ago... How nostalgic.
Quiz Space: Is the Apotheosis of the Kaslanas any good?
Otto: ...It's all right.
Mei: Do you really like showing off Bronya and Kiana like that?
Quiz Space: ...It's all right.
Himeko: Oh, wow. So I die in the timeline without Hong Yu? That's pretty tragic.
Quiz Space: Dead in the truest sense, without a single regret.
When the quiz space shows the Valkyries what happened to Hong Yu in his previous life, they are stunned.
(A quiz-space story featuring the protagonist seems to be pretty rare.)
The plot features both original material and stories from Honkai itself.
