Narumi exhibits an authoritative and loud demeanor, frequently barking commands at his subordinates. A defining trait is his established preoccupation with coffee consumption.

In his operational capacity, Narumi oversees the deployment and actions of officers Ken, Eleanor, and Gora, along with their respective robot partners. His primary narrative function involves directing the unit's urgent response to the hijacking and subsequent rampage of the advanced MBT-99A tank prototype.
