Persona is like the most insanely Japanese game there is. Yeah - an incubus is a European legend but it's in a Japanese game. In European mythology? Incubi fucked women while they slept. In Persona? They've got a horn coming out of their crotch longer than their goddamn arms.
You've already said that you can understand and respect my beef with - again - "aspects" of Japanese culture. I'll reiterate - I accept a lot of weird shit in anime and video games. Less in anime because I saw Urutsukidoji in an arthouse theater in 1992 and had no idea what I was walking into. You get that shown to you as if it's normal and not at all weird and absolutely the thing you feature the weekend after My Neighbor Totoro and you start to question what people find acceptable.
Persona 5 was my Urutsukidoji video game experience. There's plenty of stuff that's cool, neat, interesting, admirable and worthy of emulation. But there's some shit that's just straight up not right and arguing about European demonology does not negate that. My receptionist is a gamer. I can't talk to her about Persona because it sails dangerously close to sexual harassment. That, to me, is reason enough to call "aspects" into question.
