Reimi is a police officer in Team Warriors, partnering with colleagues Maki and Yuka. She possesses a passionate attachment to electronic devices, reacting with intense anger to any damage due to the significant financial burden of replacements straining her budget. This reaction manifests during operations, including violent outbursts against adversaries when her phone is destroyed.

Her key involvement occurs during a critical mission investigating a white slavery ring. While undercover at a nightclub connected to criminal Samuel McCoy, she and Maki intervene in a kidnapping attempt but are overpowered by McCoy's bodyguard Gonnack. They succumb to poison needles and are hospitalized, mirroring Yuka's prior capture. After recovery, Reimi disregards official protocols, assisting Maki in commandeering police assault gear and vehicles to infiltrate McCoy's compound. Wearing skin-tight battle armor, she engages in direct combat against McCoy's forces, contributing to Yuka's rescue and the dismantling of the trafficking operation.

Following the mission, Reimi recuperates in the hospital alongside Maki. During their recovery, Yuka jokingly suggests returning to the initial nightclub, prompting reactions of shock from Reimi and Maki. No further canonical appearances or developments occur beyond this mission.
