Bug Ego is a psychological sci-fi manga series written by ONE (creator of One-Punch Man and Mob Psycho 100) and illustrated by Kiyoto Shitara, published in English by VIZ Media under the VIZ Signature imprint, exploring reality-altering phenomena and the limits of identity.
 
When a high schooler encounters strange “bugs” in reality—specific actions that trigger impossible outcomes—curiosity quickly turns into something far more dangerous. As he and others experiment with these glitches, the boundaries between self, control, and consequence begin to break down. Bug Ego blends surreal concepts with grounded tension, delivering a quiet but unsettling psychological experience.
