Hello,

Here is his full Kit at 3*.

Hi

I made a look around in public files that are available in our Discord.

Your original question:
Shisui [MAS] does not have a passive that has a fire attack to reduce the opponent's critical rate by 10%. The unit coming close to it should be Shisui [Kimono]

As for the missing part of Shisui [MAS] description. This is what is missing in its original description.
