Intro
Today is the day of the open class at Starlight Elementary School, where Hari's crew attends. However, this isn't a 'Parent Open Class,' but a 'Student-Run Open Class.' It's a special event where students from each class move around to observe and participate in the lessons of other classes.
Unfortunately (?), the members of Hari's crew are all in different classes, so they have to visit each other to participate.
