All Free!: Zettai! Musabetsu-kyuu Chousen Joshi Den

Flexibility beats raw strength! That is the essence of judo. It may be so. But in fact, there's actually freedom of skill for the fighters! The speed of Kumite and the ability to read the opponent's next move before it happens...This little hero embodies all those things!!! Meet Jun Mifune! A judo girl who recklessly and indiscriminately challenges adult men.
