Red Dragon's Wish

Kuroko is a 14 years old young boy who likes playing basketball. he was now a first year of Teiko high. He was living a normal life with his friend, Ogiwara, his crush who went to another school which is kinda disappointing that he won't see him until he is a regular basketball player and would have a basketball match with Ogiwara's school. but all of that change when he reads an old book about the "Red dragon's Wish" which it drop from the books he had bought from a bookstore. It's weird. he didn't even remember buying that kind of book. Then he realize that the book's cover is similar to his necklace.
