Keima finally meets someone whose heart he can't read like a game flowchart, and the entire dynamic shifts. Tenri arrives carrying a mystery that doesn't resolve cleanly, doesn't need to, exists just to make him question whether his playbook actually works on people who matter. Two episodes of summer heat and genuine uncertainty, where a girl who seems simple turns out to be the variable he never coded for.

Summer vacation means one thing for Keima: as much gaming time as possible. His plans are interrupted when Tenri, a shy girl he knew before, moves back into the neighborhood. She seems to be carrying a lost soul inside her, so Keima and Elysia set out to uncover what her heart is hiding. The two-episode OVA mixes comedy, romance and supernatural elements.
