No you arent blind he got a misstake there between Hagakure and Kasha has to be Meikyo Shisui he mentioned it later

My Fault

Hakaze > Shifu > Kasha > Hagakure > Hakaze > Jinpu > Gekko > Iaijutsu > Hissatsu: Guren > Meikyo Shisui > Kasha > Gekko > Yukikaze > Hissatsu: Kaiten > Iaijutsu > Hakaze > Hissatsu: Shinten

Thats the opener but I think with WAR support
