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.
Kurosaki Ichigo is a 15 year old boy that has an ability to see ghosts/spirits. Because of his ability, he is able to meet a female death god (aka Shinigami) named Kuchiki Rukia. To save his family and friends from unwanted soul-eating spirits (Hollows), Rukia transfers her Shinigami powers to Ichigo.
