Bug Ego (Japanese: バグエゴ, Hepburn: Bagu Ego) is a Japanese manga series written by One and illustrated by Kiyoto Shitara. First published for two chapters in Young Jump Dai Ichiwa—a supplement magazine of Shueisha's seinen manga magazine Weekly Young Jump—in April 2023 and January 2024, the manga began a regular serialization in the publisher's Ultra Jump magazine in October 2024.

Synopsis

The series follows two Japanese high schoolers: the socially inept and physically diminutive Takehiro Kokudo, and the charismatic, empathetic Makoto Hitsujia. Takehiro finds and eventually shares a mysterious notebook with Makoto, which details various bugs in reality, bizarre actions or events which result in otherwise unexplained phenomena. The two resolve to work together to experience and document the effects of the bugs, often dealing with the fallout suffered by failing to heed the warnings detailed in the book. The two are later joined by Hashira Yuki, a highly competent yet overworked classmate who seeks to regain the lost joy of her youth.
