Occasional skimpy/low-cut outfits. For example, the NPC that trains Karen wears a low-cut shirt and shorts that are low enough to expose her pubic bone.

A brief bath scene shows most of a girl's breasts and, very briefly, her bare butt (no explicit detail).

Frequent gun violence; however, unlike Sword Art Online, it is established that none of the in-game violence can hurt the real-life players. Blood is usually portrayed as non-realistic specks in the air; however, occasional sprays/pools of blood can look more realistic.

Other methods of violence used in-game include knives, swords, kicks to the head, and biting.

Occasional mild coarse language ('damn', 'hell', 'bastard', 'crap') in the official English subtitles. The English dub has occasional use of moderate language, including 'sh*t', 'goddamn', 'asshole', 'bitch', and 'dick'.
