Lunar Legend Tsukihime

The news reports that last night, a girl named Andou Tomomi was found dead. She had left her friends around 7PM to ride the ferris wheel. Shiki is worried about Akiha, who has been acting strange since last night. He asks if it was something Ciel said. She gets up angrily but then faints. Shiki wants to call a doctor, but the maids remind him that Akiha hates doctors and assure him that she will recover with rest. Shiki is still concerned. Why would she get sick so suddenly? Kohaku explains that this often happens whenever Akiha suffers mental anguish. Shiki realizes that he is the cause and decides to stay with her tonight...
