Adult only
Steam players tag MONMUSU as Sexual Content, Nudity, Hentai and NSFW, strongly enough that it is among the game's defining tags rather than an incidental one. Steam rates this Adult Only for sexual content. Expect explicit sexual imagery — this is the uncensored release, not a toned-down one.
Coilr does not show screenshots for this game. Its cover art is blurred here for the same reason. Both are on its Steam store page, behind Steam's own age check.
This reflects how Steam players have tagged the game, not an official age rating, and Coilr does not inspect game content itself. Valve's own maturity description is on the Steam store page. Coilr users can keep games like this off their public profile in settings.

This game's player count is measured about every 24 hours. Steam allows a limited number of requests per day, so the busiest games are measured every few minutes and quieter ones less often. The shape of the curve is real, the fine detail between points isn't recorded.
