But I have developed views on them. In my opinion, Rukia and Ichigo's relationship is very...complex. I don't view them as just close friends, but I can't view them in any sort of romance dynamic either. In my opinion, Rukia has a love for Ichigo. And Ichigo has a love for Rukia.
Like Ichigo, Hollow Ichigo has an astounding growth rate. He gains any power Ichigo does, evidenced by his use of Bankai. He could use the black Getsuga Tensho before Ichigo, despite both learning Bankai around the same time. His own Getsuga Tensho is incomparably stronger than Ichigo's.
