Gyuwanburaa Jiko Chuushinha

In this manga, we follow Mochizuki Dorao, a regular at the Iisuu Chii parlor (a play on the 1-4-7 suji and the word for the Souzu suit being the same used in "parlor") and a professional gambler who can always win no matter the opponent, as he plays against different opponents and visits different parlors — ones crazier than the previous ones —.
