The Senkyutai (穿弓腿 Senkyuutai?, "Drilling Bow Thigh"), also known by its informal nickname "Roll Kick", is one of Yang's special attacks, introduced in the Street Fighter III series. Yun also used this technique until it was replaced with the Nishokyaku from 3rd Strike onwards. The move is one of many Northern Praying Mantis Kung Fu (螳螂拳, "Praying Mantis Fist") techniques.
