Furinkazan (風林火山, Fūrinkazan?, "Wind, Forest, Fire, Mountain") is the Noble Phantasm of Takeda Harunobu.
Summoned to the land of KaiWP, where he is at his most powerful, Shingen has come into existence as a symbol of the concept of Takeda, and wields power far greater than he did in life.
He is able to manipulate magical powers of four different attributes, and unleash them as his own military strategy. One of these is tremendously powerful on its own, so one can imagine how powerful they can be when unleashed one after the other.
Once he swings his GunbaiWP, the winds blow like a storm across the battlefield, and he will take up position without the enemy's notice, crushing the enemy army with a cavalry charge enveloped in flames and a finishing move, the Shifting Mountain Method.
"Act as fast as the wind and as silent as the forest, then invade and plunder as fire, and be as steadfast as a mountain."
It is also possible for Shingen to summon his Twenty-Four GeneralsWP and deploy the Takeda Army of old, but this is a double-edged sword, as it can severely damage his spirit and, in some cases, even annihilate him. It also consumes magic power that an ordinary master cannot withstand, so it is unlikely to be used outside of extreme circumstances.
