Dan Tetsuo (
Dan has dark skin and spiky black hair tied up with a gray headband. There are two shoulder-length strips of hair beside his face. He also has black eyebrows.
Dan was at the football ceremonial entry for the nationals of the Football Frontier along with his teammates. Before the match with Inakuni Raimon began, all Tonegawa Tousen's players gathered around Endou Mamoru, who encouraged them to fight. The match started and Dan tried to steal the ball from Inamori Asuto by sliding but he managed to avoid it. After Raimon's failed attempt, Tonegawa got the ball back and they kept passing with precision, showing everyone perfect teamwork which made a big impression on Inakuni Raimon's players. In Sakanoue Noboru's flashback, it was seen how they met with Endou for the first time when he prepared for training a huge pile of tires. They were surprised when Endou explained what was his plan to strengthen Japan and face the world. They got excited that they could take part in the tournament if they worked hard. However at the same time they doubted whether it was possible since their soccer club was completely new. Their conversation ended with a quarrel and Endou calmed them down. Later he explained that he chose this school because it reminded him old times when there wasn't soccer club in Raimon yet. Although most of them were just amateurs, Endou promised to teach them everything from the beginning. Dan felt a huge relier. Later during the training he was wondering if it would be really helpful in soccer.
With Endou's support the team was motivated and ready to action. When Raimon counterattacked, Endou easily protected the goal and encouraged the team to keep fighting with Shimomachi Kakeru and Kaname Mizuho scoring the first goal quickly after. When the second half of the match started, both teams were fighting fiercely but Raimon was in disarray. Unlike them Tonegawa's players were supporting each other and warming up. Later Raimon's players united their efforts and managed to score the first goal, tying with Tonegawa 1-1, but they were unable to score another because of Endou's Fuujin Raijin. Although at the end Tonegawa's players were really exhausted they didn't give up. With new player Tanukigahara Ponko they fought to the bitter end. The last Raimon's shot was too powerful for Endou and Tonegawa lost with 2 points. Despite this they were still happy and proud that thanks to Endou they went high.
