Kurumi's the spirit nobody expects to soften, the one who makes you believe something genuine could exist between her and Shidou despite everything you know about her. That planetarium scene doesn't just look beautiful, it rewrites what you thought you understood about her underneath all the obsession. You watch her remember she's human for a day, and it costs everything, and that's the whole show.
Shidou Itsuka runs into Kurumi Tokisaki at the Tanabata festival and finds himself agreeing to spend the day with her. What starts as an awkward date winds through a planetarium, food stalls, and a mock wedding ceremony as Shidou watches the notoriously dangerous spirit reveal a gentler side he never expected to see. Meanwhile, his friends Tohka, Yoshino, and Kotori search the festival grounds for him, unaware of what he's discovered. The afternoon becomes a strange kind of date where Shidou must reconcile the girl laughing beside him with the "Worst Spirit" he knows her to be. Kurumi's unpredictable nature keeps him constantly off-balance, never quite sure whether to trust the softness she's showing him or remain wary of what lies beneath. As evening falls and the festival winds down, the truth behind her behavior begins to surface, forcing Shidou to reconsider everything he thought he understood about her. This is a lighthearted romantic moment caught between the supernatural and the ordinary, where one day at a festival becomes far more complicated than either of them anticipated.
