Comments of chapter undefined of Bleach: Gazing Mirage

hey getsuga tenshou was literally a technique of zangetsu. not anyone could use that.. and if you are talking about ganjo using it, it is because he had absorb his reatsu during the fullbringer arc.. if anyone could channel reatsu and throw a slash into enemies like ichigo then it would never be called a shikai technique..and if you are talking about engetsu.. then reread again what zangetsu and engetsus connection before ichigo learned the final getsuga.
