So beside Hikaru No Go I don’t know if there are any other anime’s/Manga that are Go related.
So I was thinking of a light novel, that is a mixture of Hikaru no Go in some aspects and Akagi.
Akagi Description - One stormy night, Nangou is playing a game of Mahjong with the local yakuza. Soon, he finds himself on a losing streak. If Nangou loses, he will have to pay with his life. Suddenly, a young teenaged boy, Akagi Shigeru, barges in, drenched from the rain. After watching a couple of games, he offers to replace the struggling Nangou. At that moment, a new legend was born.
and a mixture of other aspects of course to keep it original and interesting. I’m not really good at making story’s so I cant do it. Someone else can though.
