Kizuna Ichigeki

Kizuna Todoroki, a 12-year-old martial artist, was already a World Martial Arts Tournament champion at her age. She had used her winnings to pay off her grandfather's 100 million yen debt, but her life was about to get complicated. A reporter arrived at her doorstep to interview her about her skills and the Wadachi Ju-ken school, which her grandfather founded. However, Kizuna's household was soon flooded with challengers who hoped to defeat her before her 13th birthday and take her title as world champion.
