idk why you guys find it confusing:

White bit masaki and infected here with "hollow" influence White died Ichigo is born with Quincy, Hollow AND Shinigami powers Ichigo steals Rukias power and awakes his Shinigami side Ichigo trains with Urahara and his Hollow awakens "Zangetsu" appears calling himself the Zanpakuto spirit, while being th Quincy's spirit For some reason, Ichigo's shinigami's power, due to the infection, is his hollow powers

"Zangetsu" is exposed as a fake

Getsuga tensho may be Zangetsu dragging Hollow Ichigo's power as Shinigami, not really making it his own(proof: Hollow ichigo always made better use of the getsuga)
