No, no fans always tend to over-exaggerate the ideas and affections of characters in their paborito stories. Toboe is in fact a boy and so is Tsume and they have madami of a father-son to big brother-little brother relationship.
The larawan you saw were just fans expressing their fantasies, this is not the REAL story.
uh no they are NOT GAY. Toboe just wants to help out Tsume in any he can and keep the pack happy.even though it doesn't look like it until episode 29 and 30,Tsume really cares and has a horrible past[that resulted in his scar].and Tsume had actually CRIED when he had to say good-bye to Toboe.he then[as I saw]fought back tears when he had to 'put down' Hige.he even risked bring killed sa pamamagitan ng Darcia to help open Paradise......okay I got off topic but the point is that Tsume and Toboe have a Big Bro-Little Bro relationship,not........a gay one.
