Hotaru’s school report, from the brief period where they try sending her to a regular school, says that she is a very imaginative child but that one might perhaps be a little concerned about the strength with which she clings to her made-up family?
Haruka frames the report and hangs it in the living room.
Also, Michiru has carefully coached Hotaru in writing like a kid, because otherwise the teachers get so freaked out.
It all ends up moot, anyway. They can’t change schools fast enough to make people not get the creeps over her ridiculous growth rate. Setsuna takes over as main home school teacher.
