Bug Ego is a supernatural seinen manga written and illustrated by Kiyoto Shitara, co-created with One, that follows high school transfer student Makoto Hitsujiya as he discovers a hidden layer of reality through his eccentric classmate Takehiro Kokudou. Kokudou reveals the existence of 'Bugs' — strange, rule-bound phenomena that produce specific outcomes when precise sequential actions are performed, from summoning bird droppings with vending machine inputs to lifting superhuman weights.

What makes Bug Ego exceptional is its genre-defying blend of psychological horror, surreal comedy, mystery, and sci-fi wrapped inside a deceptively ordinary school life setting. The manga asks a deeply unsettling question: if reality itself has exploitable loopholes, what are the consequences of using them? As Hitsujiya and Kokudou's friendship deepens, the Bugs they uncover grow darker, more dangerous, and harder to explain — pulling readers into a world that feels like a drama and an action thriller all at once.
