Akagi: Yami ni Oritatta Tensai

r/Seinen · If you had to pick your ultimate favorites, what are the best manga you've ever read?

The ravages of time, Dr stone, usogui, akagi + ten.

r/Seinen · Any good seinen animes?👀

Kaiji: The Ultimate Survivor, Akagi, One Outs, My Home Hero, The Fable

r/Seinen · Suggest an anime / manga similar to berserk and death note

berserk = Claymore, The Guyver: Bio-Booster Armor , Ninja Scroll mix of both - Legend of the Galactic Heroes (162 episodes xD) death note = detective conan (first 250 episodes), Kaiji, akagi, one outs, code geass.

r/Seinen · Suggest me a mature read based on my favourite manga/anime list (in order)

Kaiji, Akagi

r/mangarecommendations · Manga recommendation based on my fav mangas?

Another works of Nobuyuki Fukumoto ("Akagi", "the legend of the strongest, Kurosawa" and etc.), Maybe manga by Arawi Keiichi ("City", "nichijou", "Amemiya-san"), "Genikasuri" by Toshio Saki

r/mangarecommendations · Recommendations based on my current list?

I've pretty much recommended them there, haha. The only one I didn't really mention was Akagi, since Mahjong is hard to get into but if you can understand it, it's a brilliant manga/anime.
