Mami Shimada (島田 真美, Shimada Mami) is a fictional character and a 2nd Year High School Student of Hanazono High in the Kunio-kun series. She is Riki's girlfriend in Downtown Nekketsu Monogatari, who is kidnapped by Yamada.
Mami is a kind and innocent individual who saw through Riki's rough side and found a kinder personality within him. Because of that, the two of them started dating.

Downtown Nekketsu Jidaigeki
A remake of Downtown Nekketsu Kōshinkyoku: Soreyuke Daiundōkai, Mami is again the cheerleader for the Hanazono High School team. Mami is also part of a DLC team, the cheerleaders.
