Ryusei Karate Do is based on the todi technique of kaishu-naiko-ho (an open-hand method designed to develop inner power or ki).
Shuri-ti is known for its sharp, agile and very quick techniques. For its part, Naha-ti is famous for its powerful defensive and attacking techniques. Chito-Ryu is the karate created by Chinen Kinchoku (Tsuyoshi Chitose) to incorporate the strengths, and avoid the weaknesses, of Shuri-ti and Naha-ti. Ryusei Karate-Do was developed to incorporate the essence of both todi and Chito-Ryu, and to become a legitimate part of their lineages.
