Undertale: Memories Return, Three Souls in One Body

(No System + novice writer + Undertale + ensemble cast + selfcest) A note before you read: I'm not very good at narration, and my ability to express myself relies on being able to argue my point. The narrative perspective is all over the place, but you, I, he, she, and It aren't. The genders of our own bones are all... well, it's normal for a collective consciousness. (The pronouns in this story are confusing. Please don't dwell too much on some of the wording; the author may have simply mistyped.) There will definitely be OOC moments, selfcest, fights, and original headcanons and fan-created content. The story is probably about a bunch of kids who don't know anything going on an adventure... The three protagonists are all kids, and they're all errors. They're all the same person, or skeleton. The first is Linjie Zhi, a fixed error. They seem to be one of the few errors for whom being an error is a negative buff. The second is Zhou, also known as Instant. They're an error too. The third is Chushi, the first Cage, before it looped or split. They're sort of the original, too. Part of the reason for the loop is to find It again. They're an error, and they've gone missing.
