Girl looks like she came straight from a gacha game
id she not? I don't actually know how Shiny Colors plays
Yeah Shiny Colors is a gacha game, though the funny thing is that from what I know neither of these characters have any outfit as suggestive as this in game. A lot of outfits in IMAS are not sexual at all. Usually at most there's a swimsuit outfit that's pretty reserved, and I don't inherently view swimsuits as sexual.
There's a variety when it comes to gacha games and not all of them are fan-service focused. Comparing say two Korean gacha games, there's a world of difference between Limbus Company and Nikke lol
