Kaiji is in my top 5 anime list. The art style is unique, the music is great, and Kaiji has great style. It’s different in many ways, including the fact that there are no women in the anime (excluding the convenience store co-worker, who is a minor character).
If you see Kaiji’s signature long, pointy nose in an anime, it’s a reference to Kaiji. It is usually shown when a character wants to play a game, and the character’s appearance changes from the original art style.
