Axe Kick (カカト落とし, Kakato Otoshi) is an offensive fighting move.
The user raises their leg higher than the opponent's head and pulls it down quickly. It is mainly used to strike the enemy's head, shoulders and also the nose.
This technique requires a lot of flexibility for stretching the leg at a high level. Yuujiro Hanma is known to use the Axe Kick a lot more than other fighters, being very flexible (he's often lifting his leg with a calm stance).
