I'm not much for anime, but I seem to pick the decent ones.
I also started watching Sanda last night, but mostly because of pre-Christmas mood.

It's set in near-future Japan where the birth rate is so abysmal that Sanda and Fuyumura are part of a generation that's both privileged yet controlled by the adults of Japan. Christmas is forgotten in Japan given the Japanese government does not want the children to have notions of hope or desires, and have returned to arranged marriages and engagements in order to encourage and control population of Japan.
Sanda is a 14 year old student who discovers he is a decendant of Santa Claus, and that whenever he wears red, turns into a buff-Santa Claus.
Yeah, I also have read Sanda manga before.
It's a decent one. Weird but I kinda like it.
Its anime version right now is also on Top 10 in both Anime Trending and Anime Corner.


I read it because it's written by the same mangaka who wrote Beastars, a manga which kinda looks like Zootopia at first, but it's more bizzare, darker, and fucked-up.
It's also exploring romance between interspecies animals, between a carnivore and a herbivore to be exact, which is really weird.
There is also anime adaptation of it.
