Uoshima Sameharu (
He has tanned skin and is very tall in height, with a muscular build. He has shoulder-length, curly, black hair which forms a spike on top of his head and small gray eyes.
As soon as the match started, Inakuni Raimon attacked. Uoshima tried to stop Goujin Tetsunosuke but he quickly passed the ball to Inamori Asuto. When Kozoumaru Sasuke shot with his Fire Tornado, the Seishou team was shocked. In the second half of the match Seishou continued to pressure Inakuni Raimon and Uoshima got the ball from Kotono Tomio. When Haizaki Ryouhei scored 10th shot with his Overhead Penguin, Uoshima stood next to him, looking at the Raimon's players. After the match ended, all Seishou players were smiling, satisfied with their winning. The last game in the preliminaries Seishou played again with Inakuni Raimon but Uoshima was sitting at the bench. This time Seishou lost with a score 4-5. In the next match with Outei Tsukinomiya Uoshima was benched again. From the beginning, Outei players pressed on Seishou. They scored quickly 3 goals and kept shooting with ball to the opponents to weaken them mentally and physically. When Outei used their tactic Grid Omega, the Seishou players were unable to continue their play and the match was forfeited. Uoshima appeared later when together with his team watched the final match of Inakuni Raimon and Outei Tsukonomiya.
