...he had the B-type people and the A-type people sitting separately.

What if you were AB, am I going to get sawed in half 🤣

Yeah that isn't uncommon thing that businesses do in Japan. Hell a lot of animes will give blood type in the character bio. My Hero Academia is a notable example.

WTF?!?!? I mean I don't mind discrimination at all, especially such exotic discrimination. It only gets evil if it's mandated by governments or society at large but being a great fan of all the Studio Ghibli movies I wonder what's behind this bias.

i had someone here on the NostrVerse tell me that blood type is more important than race ... it's obviously laughable but in Japan everybody is a Jap and you still have to discriminate somehow so ...
