Next was Kashagiri Hiromitsu.......there seems to be no real basis to the association to the figure of Kenshin Uesugi (上杉謙信) and the blade itself i can find so far.

But,the Youkai,the Kasha,mentioned the story does have a basis in the myths and legends.

As for the blade itself,given i see the name pop up reference japanese games....I don't know where this even pops up,really,where does this originate from?

A.The legend goes that a samurai by the name of Matsudaira Goemon?* who was helping with the disposal of corpses ,suddenly the sky darkened and a hand appeared from the dark clouds which tried to snatch the corpses.Kenshin Uesugi used his blade to cut that hand,which belonged to a Kasha.

(Strangely the JP wikipedia does not have this.)


 * There is no such figure in history during Nobunaga's time,only Ishikawa Goemon and that guy is a ninja,not a samurai.

B.It is one of the thirty-five legendary swords listed in Uesugi treasury records.

C.The Sword is a ōdachi.

Chant:

"Protect me and defeat my enemy,I ask for the removal of my curse! Erasing Ten Fists Form:Burning Soul! Kasha,come with me and refuse to perish,like silk in the fire! Flash of the First Cut! Flash of the Second Cut!Purification of the Third Cut!

(Will look into this later.)
