Clannad - Season 1 Episode 12 Hidden World
8.30 24 minutes Kotomi returns the violin to Rie Nishina and becomes friends with her. Kotomi changes her usual routine and starts attending her classes. Due to Kyou's idea, she, Ryou, Kotomi, Nagisa, and Tomoya go out together as a group and have fun in town. While out, Fuko makes an appearance in, but no one remembers her. The next day, Nagisa runs up to Kyou thinking Ryou got in a bus accident, though when they rush to the scene, they find no one was hurt; however, Kotomi has an emotional episode and collapses while screaming out. Kotomi leaves early that day, but when Tomoya, Nagisa and the Fujibayashi twins go to see her later, there is no answer at her house. After they leave, Tomoya goes back and runs into the strange man from earlier; he finds out the man is an acquaintance of Kotomi's parents.
