Mami

Mami, full name Shimada Mami, is a 2nd Year High School Student of Hanazono High School in the Kunio-kun franchise. She is Riki's girlfriend in Downtown Nekketsu Monogatari, who is kidnapped by the Twin Dragon Brothers. A kind and innocent individual who saw through Riki's rough side, which allowed her to find a kinder personality within him. The two began dating for this reason. Mami appears as a secret final boss, along with Hasebe, if the player beats the game and destroyed all Sabu Statues. Unlike in Downtown Nekketsu Monogatari (River City Ransom), in River City Girls she and Hasebe are re-imagined as snobby, diva-like 'popular girls', and there are minor hints that the two have a long-running unfriendly rivalry with Kyoko and Misako.
