If a Ninja moves into a tile occupied by a Guard or if a Patrolling Guard is moved into a space occupied by a Ninja, it is presumed the Ninja has no alternative but to kill the Guard and must take time to hide the body.
The instant a Ninja moves into a Guard, the player
- picks up the Guards meeple and places it on the card they have just played
- discards their next two Movement Cards face-down onto their discard deck and
- misses their next movement turn. (Then play as normal on the following Movement Turn.)
If a Ninja takes out a Guard on their final Movement Turn (6th card) they do not miss a Movement Turn as Movement Phase has ended.
