Guys i just started bleach and i'm in ch.166 and my question is, while fighting byakuya , hollow ichigo appears and fires a black Getsuga Tenshō. After ichigo deals with his hollow self he gathers energy for another Getsuga Tenshō but it's still black even after it is fired.
why is it still black?
if this will be explained latter or will become spoiler please say so.
