Manabe - kun is known to be a pervert and sometimes thinks about dirty thoughts about Kotoura - san, and as Kotoura - san can read minds we can see those thoughts. (there is no nudity, the only nudity in Kotoura - san is Kotoura - san's side boob in Manabe's mind).
Violence & Gore
Mild
We see someone about to whack a girls face but we don't see the person hitting the girl.
A second later we see a girl who has blood coming out of her head.
Profanity
Mild
A use of "damn" "hell"
Frightening & Intense Scenes
Moderate
When the girl was going to get hit in the head she was saying ''I'm Sorry'' over and over again. This might be frightening for young viewers.
