The next day on the way to school, Tomoya is almost run over by a girl on a scooter named Kyou. Tomoya also has a couple more weird encounters with girls that day. Later on he helps Nagasi with creating posters for the theater group she wants reestablished at the school.

Tomoya is on his way to Nagisa's house for a visit but ends up going to Youhei's house instead. The next day he helps Nagisa out with her theater club.

The Student Council has decided that Nagisa can not re-establish the theater club. As Tomoya and Youhei are helping Nagisa recruit students to the club, they come across the ghost of a girl that was killed in an auto accident.

Tomoya and Nagisa decide to investigate whether Fuuko is really Ibuki's sister. After meeting her, they give congratulations on her engagement. This confuses Ibuki as she has only told Fuuko about her engagement. Nagisa and Tomoya begin to wonder if Fuuko is the rumored ghost girl.

Tomoya goes to Furukawa's house to pick up Nagisa and Fuuko and head off to school. Once at school, Fuuko tries to find people to attend her sisters wedding. Nagisa invites Fuuko's sister to the Founders Festival.
