He initially comes to Ikki's school in search of the culprit who went around fliping female student's skirts, which included Karin among the victims. He Robattles the students such as the members of the Screws Gang, defeating them with ease. Kouji would eventually face Ikki in a Robottle in the school, but would end up losing the first encounter. He is calmed down by Karin, and he would look elsewhere.

Kouji would be met once more in the woods, both him and Karin searching for the Ghost in the woods who was stealing parts from other Medarots. He would search an area of the woods with Karin, redirecting Ikki and [[Arika Amazake|Arika]] away from where he is searching. Eventually Kouji and Karin are separated after some time due to Karin becoming fatigued from searching, with Kouji eventually finding Ikki and a suspicious Medarot in a cave. He would try to fight the Medarot, but Ikki would defend the Medarot, and after losing to Ikki once again, Kouji would have the situation explained, and the true culprits, the [[Roborobo Gang]] would show themselves, Kouji taking on one of them while Ikki fought the [[Shiokara|other]].

On [[Medarot Island]], Kouji faces Ikki once more in an official Robottle Tournament, him being the final opponent in the tournament after defeating the A Block. He would face Ikki in one more Robottle, but ultimately would lose in that battle.

Kouji's starting Medarot in Medarot 3 is dependent on the version of the game once more, with [[Excise]] replacing Smilodonad in the Kabuto Version, and [[Unitris]] replacing Warbonnet in the Kuwagata Version.

 

 

 

Kouji goes around town looking for Ikki. Eventually, he goes to the Geofront Scientific Laboratory where he finds that the RoboRobo executive [[Shiokara]] has taken hostages with Medals as his ransom. Kouji challenges him to a Robattle and wins, making Shiokara flee. He manages to grab on a RoboRobo grunt, who explains to him that the RoboRobos plan to take over Earth Mall by capturing a lot of medals. He lets the grunt go and meets Arika, who tells him she figured out Ikk is inside the laboratory he just left. Surprised, Kouji hands her back Ikki's Medarotch and goes to brief Karin on the situation.
