@Midoriha being suspended here means they're being isolated from the rest of students, not taking days off from school. So they're still allowed to contact them outside school, but not inside school.
Hmm there seems to be a discrepancy between what's shown here and Super Cub, where the girls practically live on their Super Cubs. Tho I guess in here it's local school policy. Ucchi u got this, visit her home!
