I've been a longtime Showa Genroku Rakugo Shinju fanatic. The historical theme is so well-done, it's engaging, the messy queer vibes are immaculate. I also love Banana Fish for its grungy city ambience, heart-wrenching romance and suspense.
I just finished watching Monster, which to me felt like a combination of the two (plus several other elements of course). It's seinen but honestly you could have fooled me—Women characters play prominent roles and are written to feel so real. There are subtle feminist undertones throughout, and sexual assault is very, very rarely used as a plot point. There's no service, and bodies are drawn so beautifully. There is a sense of precision towards each character’s race, backstory, and personality that also reflects in their design, no matter how unimportant they are. (Kenzo Tenma in particular was so swoon-worthy in the plain, fresh, Ghibli-esque way.)
Highly, highly recommended. Go watch it on Netflix, right now.
(The animation is already spectacular, but there are also upscaled versions of the episodes available online somewhere if you'd like better quality.)
