When the Katana approached me while flying I caught it in midair and strangely when my hand touched the sword my horns broke down into reiatsu and got absorbed by it and the sword started to change the scabbard became covered in black bandage with an ice blue second handle at the base of the scabbard (hole for the sword), I took out the blade and was surprised to see it completely black with a ice blue Hamon (Edge pattern) in the shape of wave the Tsuka Ito (Cord wrap around the handle) was an ice blue color like the one on the scabbard, the Kashira (Pommel) was made of pale dark grey metal, the Tsuba (Guard) was a pale dark grey metal with a pale ice blue gleam in the form of 4 four pointed star (Shuriken). I understood it was an Asauchi now zanpakuto, and it was now mine.
