He's slowly winning me over.

Okay

Serious question

What is this thing

Please give me the elevator pitch, in that it's a pitch that will send me running to the nearest elevator, where they probably have better wi-fi than my house

Disney allowed Toboso Yana (Kuroshitsuji) to have creative control over a Disney joseimuke gacha game about a magic academy full of students loosely inspired by Disney villains and related characters

MC is a poor person who got isekai'd over and become the school janitor-turned-prefect until a way home is found

Yeah, that basically.

It's pretty much targeted directly at people like me who grew up with all these disney movies and really liked a lot of the villains.

I also like Black Butler and there are definite similarities in the writing so I am pretty pleased with it so far.

Yep, it's Toboso in designs and writing (within presumably Disney limits)
