Several brief flashbacks show a young boy and his older step-sister. Both are wearing pajamas, and he's sitting up while she appears to be advancing toward him. While this instance isn't discussed or touched on, the scene may imply that he was assaulted, or was almost assaulted.

Rare mild sexual innuendo, such as a male character being falsely accused of being a 'pervert' for doing nothing, even though he's not.

One female character works at a bar and wears a low-cut dress. These scenes are very infrequent.

In childhood flashbacks, the main character's half sister is seen slapping and punching him. More physical abuse is implied.

Regular use of mild coarse language ('damn', 'hell', 'bastard', 'piss', 'crap') in the official English subtitles.

Adults are regularly seen drinking, and are infrequently seen intoxicated.

The oldest Kawamoto sister, Akari, works at a bar.

A teenage boy is found intoxicated in a flashback.

Some infrequent adult smoking.

The lead character suffers from major depressive disorder. Not frightening nor intense, but expect the series to have a sad and tragic tone.
