For the first couple of episodes there's a couple of instances where Hayato accidentally will walk in on the girls changing and in one episode Hayato gropes Ami's breast as punishment for breaking Hayato's laptop for comedic effect.

Semi-frequent female and occasional male nudity, but frontal body parts are covered by lines.

Plenty of fanservice throughout.

Shiragiku frequently strips and falls on top of Hayato when drunk.

Ami jump kicks a group of boys harassing her and Ouka; played for laughs.

Hayato falls down a flight of stairs; comedic.

Shiragiku is shown to get drunk of anything laced with alcohol.
