The Grudge Disease *NEWLY UPDATED (2026)*

This is a sequel to "The Grudge"! It is recommended that you read that story first for added context.
It's not just Aloha acting weird anymore, it's everyone.

Update: I completely re-wrote chapters 6-7 (yes, how unfortunate) recently by myself. All other chapters have had extra things added overall and small mistakes corrected.
There is in fact a third story in the works, partially up if you'd like more! (It's called the "Grudge Disorder". It's a work in progress.)

DISCLAIMER: This is a fanfiction of the Splatoon Coro Coro manga by Sankichi Hinodeya. I do not encourage the violent actions in this story. There is swearing, violence, gore, suicide mentions, and minor head canons. This is not a ship story. Some events may be sensitive to some readers. Seriously it gets intense. I've gotten comments calling this a physiological horror.

SPOILERS: In case you were curious, the concept of the diseased clones was made before the Shadow Clones were first revealed. They were not inspired by the Shadow Clones. (But honestly Goggles's sad clone is more opposite than his actual Shadow Clone.)
