Tsubomi

Tsubomi is a classmate at Salt Middle School and the girl Mob has quietly adored for years. She is friendly, popular, and utterly unaware of the depth of his feelings or the strange power he hides. To Mob she is the one normal, achievable thing he wants — a reason to try harder at being an ordinary boy.

She stays deliberately ordinary in a show full of psychic spectacle, which is the point: Tsubomi is what grounds Mob's arc in something small and human rather than cosmic. Uki Satake plays her with easy, unforced warmth, so her kindness never feels like a plot device — just a nice person Mob has built an entire dream around.
