Gouki Mutou, standing 170 cm with sharply pointed hair, is an honor student in the Logi division renowned for mastering transportation systems. His expertise spans operating vehicles from scooters to nuclear submarines, including high-speed trains exceeding 300 km/h, showcasing unparalleled mechanical adaptability.

He favors the Colt Python revolver for its low-maintenance design, accepting its limited ammunition and lack of suppressor compatibility as trade-offs for reliability. This choice underscores his pragmatic mindset toward equipment.

Approachable and dependable in crises, he frequently aids peers under pressure but balances this with a mischievous streak, habitually teasing Kinji Tohyama about romantic interactions with female classmates. The OVA highlights this duality: his failed attempt to spy on female peers at a hot spring contrasts his otherwise composed demeanor.

During critical missions, his logistical prowess shines, such as executing emergency landings for compromised aircraft. However, the OVA reveals a stark vulnerability—an intense fear of the supernatural, exemplified by his panicked reaction to encountering Jeanne d’Arc.

Affiliated with Team Carrier GA, he aligns his specialized logistical skills to support high-stakes operations, cementing his role as a vital tactical asset.
