Internal Butt Release (尻発勁, Shiri Hakkei) is a technique used in Keijo.


This technique is Maya's signature move. By using "Qigong", Maya waits and blocks her opponent's attack before blasting them. It's strong enough to send an unguarded person flying a few meters away. Maya is also strong enough to blow away a person who is larger than her, such as Tae Yokosugi.
