Misuzu (みすず) is a giant sukeban ("female gangster") from the Taiyō Academy and fictional character in Kunio-kun series. She debuted in Nekketsu Kōha Kunio-kun as the boss of round 3 she is one of the game's toughest bosses. Misuzu is generally depicted as being somewhat outside the law, but she doesn't seem to hold any grudge against Kunio and allies with him on occasion.
She returns in Shin Nekketsu Kōha: Kunio-tachi no Banka, along with Shinji and Sabu. Kunio and friends first encounter her at a pachinko hall where she was playing. After losing her money from playing, she decided to fight them since she felt irritated and wanted to let off some steam. After she was defeated, she left the scene with contentment much to the bewilderment of the heroes. She later appears at Sabu's villa after Sabu hires her as bodyguard and fights Kunio and Riki once more. After yet another defeat, she warns them about the self-destruct system in the villa.
Misuzu makes yet another appearance in Kunio no Nekketsu Dodgeball Densetsu as a playable character. Again, she is along with Shinji and Sabu. She is one of the characters that can be selected as captain and is considered to be a speed type character. Her Power Shots are "Hyakkan Love" (she charges at her target with the ball on her chest) and "Sexy in the Sky" (she throws the ball in the air and spikes it downward at her target with her chest). Her Super Shot is the "Dynamtie Hip" (her teammates propel her while she is standing on the ball, planning to hit her target hip first). Her initial teammates are Gonzou and Kiyoshi.
Misuzu is voiced by Hisao Egawa.
Misuzu leads a bonus team of girls from Nekketsu Kōha Kunio-kun and Shin Nekketsu Kōha: Kunio-tachi no Banka. While the game's Story Mode mentions her leading Taiyo Academy and participating in the tournament, they never actually appear as opponents; however, her team is playable outside of Story Mode. In this game, Misuzu has a unique attack in the form of a slow slap; it is very powerful but at the cost of possibly aiding opponents onto higher ground.
There are two instances of Misuzu in this game. One of the River City High School teachers is named Mrs. Kim, the same name Misuzu had in Renegade, though she has the exact same design as Misuzu. The other Misuzu is found in the Ocean Heights dojo and is named Suzu. Misuzu has appeared in the end of the game when she was having a date with .
- In the NES version of Renegade, Misuzu was renamed Kim and is now dressed in a cheongsam (a Chinese dress). She is unnamed in the arcade version and was changed to an American woman.
- Sukeban (スケバン/女番/スケ番) means delinquent girl or boss girl in Japanese, equivalent to the male banchō. The term is used exclusively to refer to the leader of a girls gang. Ironically, Misuzu is never seen leading a girls gang, and in Super Dodge Ball (Neo Geo) her teammates are mostly males.
- Mizusu is the final boss of the PC fan remake of Nekketsu Kakutō Densetsu.
