Bishamonten's Eight Phases - Shiranui

is the Noble Phantasm of Uesugi Kenshin as a Ruler.
A Noble Phantasm that unsheathes the ivory tachi housing Bishamonten's power. The light descending from the heavens is a long sword of divine might clad in Bishamonten's power that is capable of splitting everything in two with ivory flames. The divine work of the god of war wielded by Bishamonten.
This long sword is the Shiodome-no-Tachi, the divine armament of the Takeda clan. It is said that Kenshin sent salt to Shingen who was suffering from having his salt supply blockaded, and this sword was gifted to her as a token of gratitude.
It is not clear why Kenshin, who possessed a large number of swords, chose this single blade as her Noble Phantasm, but it is not hard to imagine that this sword meant a lot to her.
"No, it just caught my eye for one reason or another so I displayed it."
...That's not hard to picture.
By the way, on the question of why she's calling the 'Shiodome-no-Tachi' 'Shiranui'-
"Eh? Shiodome-no-Tachi sounds kinda lame so I figured if it were to be wielded by this Kenshin-chan then it should be called something cool and gave it a name myself. Doesn't Shiranui sound cool?"
