Kei Higuchi

Here is an introduction to the character ranked 9th in terms of ability at Suruga Keijo Training School. She is a counter-type athlete, first appearing in episode HiP73, titled "The Only Daughter!!!". She possesses a unique physical trait: her buttocks have thicker skin than ordinary people, making her immune to heat even when touched by flames. Using this characteristic, she specializes in the "Heated Butt" technique, which ignites her opponent's buttocks by generating friction.

During the East-West Battle, she participated in the second race. Instead of relying on brute force against Non Toyoguchi's soft buttocks, she attempted to use friction to gain the upper hand. However, she was cleverly led by Kazane Aoba's tactics, lost her footing, and fell into the water, resulting in her defeat.
