When he was young, he, along with Kaiou team were confronted by Tsurugi and were humilated by him. Some time later Kuroki Zenzou appears, calling the team to train under Fifth Sector's supervision. A few years later, as a forward and captain of Kaiou, Namikawa plays against Raimon in Kanto preliminaries. He is a SEED who has the Kaiou Poseidon keshin/avatar in his possesion. He scored the second goal against Raimon, but at the end, his keshin/avatar was easily overpowered by Tenma's keshin/avatar resulting in Kaiou's loss with a score of 3-4.

Matsukaze Tenma, a first year who loves soccer, has exceptional dribbling skills, but still has lots of room for improvement. The story starts with him entering Raimon Jr. High ten years after the first Football Frontier International, where Raimon has become famous for its soccer. However, an organization called Fifth Sector has taken control of soccer over the years, and the passion that Raimon once had for soccer is no longer there.
