Frequent sexual references.

A boy steals his crush's gym uniform (he later regrets this) and has a dream about her suggestively lying on a bed. No nudity.

A girl forces the boy to wear the gym uniform for humiliation during a date.

The same girl pushes the boy's face down into his crush's breasts in order for the both of them to be humiliated.

A teenage girl holds a boy down and rips his clothes off, intending to switch them with a girl's. From afar, this looks like attempted rape.

Some fighting (slapping, throwing people to the ground), but most of the action is taken verbally.

Extremely frequent name-calling ("shit-head," etc.).

None.

Lacks violence, but Sawa blackmails and bullies Takao nearly every single episode and tries to degrade him constantly.

The main characters see themselves as "trapped" within their small town; the series has a claustrophobic atmosphere due to this. Both characters arguably have major depressive disorder.

The characters' faces looks like they came from the uncanny valley.

Even the music is disturbing.
