Rank: B
Species: Vultures
Elements: Fuuton, Raiton
Specializations: Genjutsu, Medical Ninjutsu, Ninjutsu
Quantity: 1
Price: Free*
Description: Issei’s personal weapon, which also physically became his summoning contract following his mastery of summoning and his encounter with Shigui. The fūinjutsu pattern on it binds his blood and chakra to Nanase, the empress of vultures. Can pierce up to one inch into flesh.
Appearance: A giant shuriken that spans 40cm, with an open circle in the center and a thin strap that allows it to be worn on Issei's back. Silver fūinjutsu seals cover its entirety, and though they are easily visible to those nearby, they permeate every layer of the weapon, preventing Issei’s contract from being voided by scratches and other surface damage to the weapon.

Contract thread is right over here.

*I plan on replacing the giant shuriken currently in my locker with this to fit the way the contract thread went, so that is how I'm justifying the damage capability. If absolutely necessary, I'm willing to pay a little extra ryo to allow such a switch, but I'm tight on funds.
