* [[CelibateHero Celibate Heroes]]: Rather forced instead of doing it by their own choice. The shelters that were left for them do not contain any kind of birth-control, so Team Autumn has made a ban for any kind of sex that could result in pregnancy and the other Teams overall decide that being celibate is better, until things have settled down decently enough. [[spoiler: Ryusei and Kurumi did not follow this rule, as she is gets pregnant part-way through the series]]
