School Days Edit
In certain routes, Otome can mention to Makoto that Ii is planning a middle school class reunion.
Shiny Days Edit
According to Otome, Ii was among those in hers and Makoto's homeroom. When their homeroom teacher, Ms. Arima, tried to get the students to get along, Ii and Makoto went along with it as they looked up to her. However, Ii and Ikeda later decided that they hated Makoto (possibly because of his popularity with girls).
