Chi No Wadachi
It's fucked up, but honestly one of my favorite psychological horror manga out there. Gorgeous art that can range from subtly eerie to intensely disturbing, a family drama that's like a train wreck you can't look away from.... it's great! Also worth checking out the mangaka's other work, Boku wa Mari no Naka.

Honestly one of my favorite manga out there. Great art? Check! Homoeroticism? Check. Drama and Intrigue? Check. Complex characters with mixed morals? Check! Augh it's honestly so good. Also, check out the live action movie, it's pretty good too!

It was so incredibly refreshing reading someone else's relatable period experiences who's also nonbinary and doesn't want children.... So many of the menstruation content out there is from the perspective of cishets!
