Description

In contemporary Japan, junior high student Kyotaro Ichikawa retreats into violent fantasies and a self-image as an outsider. His thoughts fixate on Anna Yamada, a popular classmate who works as a model. When he keeps finding her sneaking snacks in the school library, her clumsy, easygoing side makes her harder to dismiss.

The short chapters build a first romance through small favors, awkward conversations, and things the two struggle to say. The focus gradually shifts from Kyotaro’s abrasive inner monologue to mutual trust and growing self-confidence. It is mostly a warm coming-of-age story, with loneliness and insecurity underneath; crude sexual jokes and the opening murder fantasies give some of the humor a sharper edge.

Pros

  • Both leads mature as they learn to trust each other.
  • Small gestures and expressive reactions carry the romantic tension.
  • Yamada’s goofy habits bring warmth to the school comedy.

Cons

  • The early murder fantasies and crude sexual jokes can be off-putting.
  • Some later storylines can feel underdeveloped.
