Eligible new subscribers can start a 14-day free trial. After the trial it continues at the selected plan's price unless cancelled.

Kurobi's library is a curated reference, not a complete one: names, details and variations differ between instructors, academies and rulesets, and the 3D fighters are schematic. It supports your learning and does not replace qualified in-person instruction, supervision or your own judgment. Discover. Learn. Drill.
