The Shito Ryu version has nothing in common with the Shotokan version. The Shito Ryu version comes from Arakaki along with Unsu and Niseishi (Nijushiho).
The opening is a little like Unsu. Three consective cat stances forward, with double yoku ukes (Outside blocks), and one hand pulls back and strikes. Just as in Sachin, and several other Naha-te kata.
