Kyan learned Chintō from Matsumora Kōsaku 松茂良 興作. The Matsumora version has an embusen at a 45° angle, while Matsumura's embusen was straight, and the angled version fit Kyan's slightness and agility well. This Chintō is another Tomari-te kata. Kyan incorporated that 45° angle into many of his fighting techniques.
Key points from Shimabukuro Hanshi:
The angled embusen.
Use of crossed-arm blocks.
Body turning and one-legged stance.
Catching and seizing.
Jumping double kick.
