凉宫春日的约定

Suzumiya Haruhi no Yakusoku (The Promise of Haruhi Suzumiya) is a non-daily experience adventure game for PSP. It is the first game based on the Suzumiya Haruhi series. Players experience cultural festival events from Kyon's perspective in a time-loop system (S.O.S. Seamless Operation System). Gameplay includes visual novel text with full voice acting, motion portraits for character expressions, and mini-games like simulated battles. The story involves SOS Brigade members preparing for a movie production, mysterious accidents, and unresolved questions like who completed the film. Characters are the iconic SOS Brigade members: Haruhi Suzumiya (the brigade leader), Kyon (the narrator), Mikuru Asahina, Yuki Nagato, and Kyonko. What makes it stand out is the innovative S.O.S. system for seamless character interactions and its tie-in to the light novels and anime.
