i find this weird. both of the above got their powers from ichigo. Sado's powers are hollow based and the blast attack el directo from his right arm is similar to getsuga tensho in shikai. Orihime's powers are similar to hachi a vizard and to a soul reaper zanpakutou check episodes 126-127 for orihime. I cant prove anything for sado besides how he mention his powers feel more at home in Hequou Mundo,during his fight with arrancar 107 ,the afro guy.
