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.
Ichigo first obtained control of his Hollow Mask & Form during his training with the Vizards (Visoreds) where they invited him to join them, he refused but wanted to seek control of his Inner Hollow. Once he obtained it, he become a whole lot powerful allowing him to face Grimmjow and Ulquiorra.
