One of those super over the top anime gacha games where they turn some real world object into cute anime girls, in this case all models of Trains get represented as Cute Girl
but the game itself is just a super intense transport management sim. The presentation may be "uwaaaa... Senpai... Help me find my caboose..." But you use that to make weebs spend 12 hours considering the logistics of station layouts
I would play the hell out of this game
