Disclaimer: This game shows an unclothed male body with the Barbie doll look (no NSFW stuff shown). I can't help this, as it's literally a game mechanic to show how much muscle your character has and the screen pops up anytime I level up a muscle group. Viewer discretion is advised.
I saw someone playing this game on stream that knew enough Japanese to know how the game is played. I know less Japanese than that streamer, but it looked fun enough to play on my own and did not seem to require enough knowledge of Japanese to create a barrier to entry, so I thought I'd play this for you guys. Now with co-commentary!
