I'll recommend some anti-moe series that I'm sure no one has watched it here
One OutsPros:
- Awesome Main Character
- Psychological Stuffs
- Mind Games
- Clever twist, like one quote I like from this series:"Yes, this game is not about winning anymore, but it's all about who violates the rule most"
Cons:
- Baseball stuffs (I don't like Baseball personally)
- Anti-moe series
- There is no character/plot development. It's all about baseball games.
KaijiPros:
- Gambling Stuffs
- Psychological Stuffs
- Mind Games
- Clever twist
- Manly-tears series, the anime with the most tears I have ever seen
- Developing Main Character
Cons:
- Err... Unique Art?
- Anti-moe series
And also, some mangas I marathoned this week
Awesome
Kuroshitsuji (The anime doesn't do its manga justice)
Solanin (not everyone pieces, very realistic manga. It's as awesome as Inio's other work, Oyasumi Punpun)
The Ravage of Time (For ROTK and War/Politic Manga fans)
Usagi Drop (Awesome Slice-of-Life/Childcare manga)
Good
Bitter Virgin (Good Romance)
Gamble Fish (The gambling stuff is not as awesome as Kaiji, but good nonetheless. I dislike the Shounen stuff thought

)
Hetakoi (Cute Romance)
Iris Zero (Good All-Around series)
Last Inning (Awesome Main Character, but the baseball is not that good. Consider this a lesser version of One Outs)
Nicoichi (Funny Trap manga)
Nozoaki Ana (Cute Romance)
Yu-Gi-Oh! GX (I always like Yugioh stuffs)
