It is very important that I fight while grasping a flow of wind in a battle between ninjas.
Snipe, communication to a friend, smoke and foggy flow, all of firearms are controlled by wind.
Because it is difficult to judge wind scale in itself from bodily sensation, it is left to a limited ninja.
Therefore when it tells a friend the velocity of the wind, it is important that all the friends understand knowledge of a wind scale adequately.
It becomes a decisive factor of a game that any kind of action understands how much velocity of the wind it is influenced by how.
