Bleach RP NPC - Sato Nagatsuki

[Sprite_Knight]

Name: Sato Nagatsuki

Age: 240 Looks 25

Description: He wears a standard kimono, but the sleeves are torn off, and instead of sandals, he wears these weird steel shoes, with razor sharp steel toes.
Division: None

Rank: Hes at the power of a strong Vice Captain

Zanpakutou: Setzuhebi (Sharp Snake)
-Sealed: A longer than normal katana and the unique thing is...it as no crossguard, completely forfeiting defense for highly increased offensive capabilities. There is a razor sharp "tooth" coming out horizontally from the base of the blade.
-Incarnation: A giant snake with a furry black mane.

-Shikai: It becomes a wide harpoon sword. The tip of the harpoon, is actually a holder for numerous slotting blades, basically allowing Sato, the ability to use his blade in a whip like way. When all the slotted blade are released, the entire blade looks vaguely like a scythe. In addition each blade has numerous tiny blades along the edge, making it like a Blade/Whip/Chainsaw.

-Bankai: It basically becomes an extending bladed whip, that excretes a deadly venom, the blade almost has a mind of its own, and can assume many shapes, even a sphere of protection around the user.

Bio: Not much is known about Sato, besides the fact that he was a rogue shinigami from the start, using his powers to terrorize those in Rukongai. Tsurai must have come to him at some point, and recruited him.

Correct me if I'm wrong, but isn't that shikai kinda like Renji's, being similar to a whip and all?
