So Slam Dunk is the highest among not only sport mangas but also mangas that are retired (and over 20 years at that)... it really is a fantastic manga and nedd a sequel =]
Is that a manga about basketball players because it sounds like it although I don't think too many Asians can dunk. Heck I'm 6'3 and can't even dunk. I'm white though and I'll use that excuse till I die.
White man can't jump is a great movie (or whatever is the name in USA).
Slam Dunk is the most sold sport manga in Japan, it is about basketball and without any super power.
It is almost real, the only think that is forced is the level of hability a japanese high schooler would have. They play close to the level of an average NBA team.
I'm white and 5'10" or so, and during my teenager time I touched the ring but couldn't put my wrist above to dunk. One inch or two and I would be able to dunk with easy. I had good impulsion.
