Teik? Junior High School Basketball Club. A super strong school with more than 100 club members, boasting several successive championship wins. But even within that glorious history, there is still a team that can without fail be called the "strongest" - a generation of five players with talents that you would see once every ten years called the "Generation of Miracles." But there was a strange rumor that there was still one person the five geniuses acknowledged as superior....
1st Quarter prologue
The Generation of Miracles (??????, Kiseki no Sedai) is an all-star team of Teik? Junior High School. It is a team of 6 players, each with their own exceptional talent. The team won everything the last 3 years, but the players (including the ex) are now scattered across six different schools. Because they are legends among high school basketball, Kagami has set his eye on each one of them. As ambitious as he is, he aims to defeat them and become the number one in Japan. Kuroko has agreed to help him get to the top. The Generation of Miracles are easily the best players in the league, only being rivaled by players like Kagami, the Uncrowned Kings and slightly Himuro.
The gate only extraordinary geniuses can enter is a figurative image of the threshold a player must pass to be called a genius, or to be on the same level of the Generation of Miracles. Because they were and are the best players of the league, it was long impossible for a player apart from the GoM to pass the closed gate, because the power of the GoM is absolute. This gate has only been forced open by Kagami, at the point when his growth has finally began to reach the Generation of Miracles. The moment when this occured when Kagamis jumping ability was so overwhelming that he could finally dunk from the freethrow line.
The Oath
"The Oath" is an agreement/promise the Generation of Miracles apparently made when they split up after Junior High school. This oath has only been briefly mentioned by Akashi during the meeting of the GoM, though it did seem to carry some importance. During that meet, Akashi says that everyone looks like they havent forgotten the oath yet. No further information has been revealed.
Weakness
All the players of the Generation of Miracles have one common weakness. This is that while they all have talents surpassing a high school boys capabilities, they still have the physique of regular high school sportsmen. This means that if they use their talents to the absolute fullest for a long period of time, their bodies cant cope with it and their talents become a burden. In short, its that they are too powerful for their bodies.
