maybe Monster

Pretty sure I'm like the only Sayonara, Zetsubou-Sensei "fan" left alive at this point.

I actualy like all the Kumeta-verse anime, SZS, Joshiraku and specialy Kakushigoto. The latter is probably the best and most acessible in general, but you wouldn't recognize these all being the same mangaka unless by the obvious artstyle. Just seeing Kakushigoto's MC roleplay as Zetsubou sensei was my own weeb nostalgia lol.

Its obviously dated now, specialy SZS, one of the gags is literally a girl Nokia phone texting. But it is some very cynical and based commentary on Japanese society, obviously exaggerated, but any weeb thinking Japan is dream land would be de-converted pretty quickly after watching it.

But it is also extremely dialogue heavy so if you can't enjoy reading subs then its just meh, art is also mid, though if you understand why the choices were made it makes sense and its kind of charming. Its unfortunate but I still think its a personal gem.

Ranma 1/2.

Flint the Time Detective. I've also met Digimon fans, but never fans of Appmon in particular. That was one of their best arca, but it got overshadowed by the dogshit Digimon Tri.

Oh we're doing obscure anime?
The dog Silver/Silverfang.
People in Japan don't even know about this one

I'm late, but Air Gear. Inline skates with souped up micro-motors in them. Gangs/clubs with sticker logo patches all battling it out on the ground and in the air. It's my shit.

Kaiji. It is so good, but most people are turned off by the artstyle.
