In the games

In Medarot 5

Koishimaru and his family had just moved to Susutake village,and Koishimaru is enrolled in the school there. Having just gotten a new Medarotch, he hopes to join the Medarot club at his new school. At the bus stop he meets Yamato Shijimi, and is shown around the village while waiting for the bus. However disaster strikes, and the duo are pushed into cow manure by two bullies, namely Osamu Samehada and Asahi Hyoumon, breaking Koisimaru's Medarotch. After getting a shower, he realizes that he's going to be late for school and rushes to the bus stop... only to come too late. He either waits for a taxi, or runs after the bus. He ends up meeting Michio the taxi driver either way. Michio tells him about some Ghosts who are appear to be causing trouble when they appear.

When Koishimaru arrives at school, he is scolded by Prof. Usumon, and meets Prof. Akane, who introduces him to the rest of the class except Yamato. After school, noticing Yamato wasn't there, he goes to the Shijimi residence, en route he hears Beni Shijimi, Yamato's younger sister crying. Koishimaru finds out that Beni's balloon floated up in to a giant tree and inside the tree he find abandonded Parts for the KBT-0 model Chrotojil/ KWG-0 Model Shinzan , a Kabuto/Kuwagata Medal and a new Medarotch.(in the manga he used his own Medal in the Body.)

Attempting to give them back, Koishimaru meets Hiko Tamayasu and Shinzan/Chrotojil. Hiko's Medarot(known as Nekuu/Omeda) assumes Koishimaru is a thief, but Koishimaru defuses the situation by saying exactly what he was trying to do, and Hiko realizing that Koishimaru is new to Robottles ,offers him advice and as Hiko is about to test Koishimaru in a robottle, the Ghosts attack, demanding that Koishimaru give up Omeda's/Nekuu's body to their master Black Mantle. But Koishimaru refuses and together with Hiko defeats and drives off the Ghosts.

After that ordeal Koishimaru returns home after arguing with Omeda/Nekuu returns home. Koisimaru then admits tha he really wants to be with Omeda/Nekuu, but knows that he has to return his partner's parts.

Later he then meets Shigeyuki, who reveals that the Chrotojil/Shinzan parts were stolen from his lab, but after a test battle, he lets Koishimaru keep Omeda/Nekuu -- much to the boy's relief.

In Medarot G

A few months after his showdown with Arakune Yakumo, Koishimaru hears about Densuke Land, a theme park dedicated to robattles. However Koishimaru's Medarotch is malfunctioning, and Omeda's/Nekuu's body is heavily damaged to the point of breaking. Shigeyuki reveals that he'd been working on a few new Medarot-- the KBT-1 Model Dichotom and the KWG-1 Model Adolphin. Shigeyuki gives Dichotom or Adolphin to Koishimaru, who then competes in the Tournament.

After winning the Tournament, Koishimaru and Omeda / Nekuu clash with the Revo-Revo Group, who seize the prize, and flee, and challenge the duo to fight them.

In Medarot 2 Core

Koishimaru is taken to the past thanks to Milky's powers. His identity is omitted, being seen only as a mysterious masked Medarotter from the future. Ikki then battles Koishimaru, who uses an exact copy of the player's current team.

This part of the story is an extra post-game event that exists only in the Japanese version; the omission in the English version makes sense due to all Medabots products in the west having marketing around only the anime (adapted from Medarot 2), omitting anything beyond that.
