Minodouzan is first mentioned during episode 3 by Zhao Jinyun as Inakuni Raimon's next opponent during the Football Frontier's preliminaries. Kameda Yukinori elaborates further, stating they are a heavily defensive team that stops anyone from approaching their goal, thus earning the moniker "The Impregnable Fortress".
They make their appearance by the end of the episode, facing Raimon. As the match start, they immediately stand side-by-side, intimidating the Inakuni as they finally realize what kind of opponents they would have to face.
During the match, the members of Minodouzan keep defending against Inakuni Raimon, using hissatsu techniques like, Mokkori Oka no Moai and Franken-shu-tein. However, as Inakuni Raimon weren't attacking, they ran out of time. This led to the coaches deciding to go for an all out attack. This attack was however stopped by Iwato Takashi's The Wall, and the counter-attack that followed lead to the 1-0, scored by Kozoumaru Sasuke's Fire Tornado.
As the match was almost over, they decided to use their Override hissatsu technique, Rensa The Wall, and moved forward, trying to take the ball and get an attack in. However, as Hiura Kirina got the ball, he used his training to use a new hissatsu technique, Koori no Ya, to pass the ball through Rensa The Wall, straight to Inamori Asuto, who scored the second goal for Inakuni Raimon, shocking the members of Minodouzan. The match ended immediately after, with a 2-0 result.
