The Anime is about Basketball. There are 5 Teens from Middle School going to High School known as "Generation of Miracles" they are the most elite players in Japan, there are 5 of them each specializing in a unique skill. Then there is a Phantom Sixth Man he was Teikos (the Middle School) 6th man. he is practically invisible on the court. Know the Phantom has gone to a High School same with GoM, its about an Average Team trying to make it to Nationals, I suggest you watch it Crunchyroll.com is a great site
