By The Hitokage Production Committee for the Hitokage bloodline.
System: There are no rolls involved with just using this skill but when another character (including a NPC) enters the same location as the Shadowed Hitokage, both players must make a dice roll. The Hitokage must roll his Kokuei + Stealth and the other character must roll her Perception. If the Hitokage roll has more success than the other characters then he remains hidden, else the other character has noticed them. It should be noted that even if the Hitokage character has had less successes than the other character it doesn't mean that he suddenly becomes visible, rather that the other character has noticed something unusual lurking in the room. Exactly what the other character sees is up to the Storyteller.
No weapon or physical attacks can be performed while the character is in shadow form and the difficulty of attacking a character while she is in shadow form is always 10 (the proverbial Lucky Shot).
While the Hitokage is in shadow form nothing can be used to adjust any dice rolls made by other character. This includes all surveillance equipment and Gleam of Red Eyes in vampires.
