Description
Ibuse is a young man affiliated with the Japanese Ground Self-Defense Force who holds the rank of First Lieutenant and serves as a teacher at a special technical school in Osaka. He is most often seen working directly under Commander Onihei Mishima, acting as his trusted subordinate and assisting in rescue operations for survivors in the contaminated capital. His appearance is characterized by messy black hair and black eyes, and he typically dresses in a white polo shirt paired with a loose blue necktie, black pants, and black shoes.

In terms of personality, Ibuse presents a dual nature that makes him a distinctive presence within the command structure. On the surface, he is generally calm and laidback, carrying himself with an easygoing demeanor. However, this tranquility can quickly give way when situations deviate from expectations; he is prone to becoming frantic and anxious when plans do not proceed smoothly. Beyond his role as a soldier, he has a notable self-promotional side, referring to himself as "Kyoto's dependable bro" in a manner that echoes the playful vanity of Aoi Fukasaku calling herself a cutie. This more immature and hotheaded aspect of his character becomes more pronounced in later chapters of the source material, where he can be childish and prone to making a ruckus. Despite these less serious traits, Ibuse demonstrates a genuine mature and responsible side, particularly in his interactions with the Medical Unit. He frequently praises their work, shows concern for their wellbeing by asking if they have been eating properly, and takes it upon himself to reassure them while becoming frustrated at his own perceived limitations in making things work.

Ibuse is deeply motivated by loyalty and a protective instinct toward his comrades. He becomes fiercely defensive for the sake of his friends, as demonstrated when he sternly glared at the prime minister's assistant for insulting the Coppelion by calling them dolls, an act of defiance that required Mishima to intervene and stop him. This protective nature also manifests in his willingness to resist authority when he feels it is justified. When being taken into custody, he was seen with fresh wounds on his face that Mishima did not have, suggesting that Ibuse acted out of line and physically resisted the prime minister's forces, leading to violence being used against him. Following this incident, he becomes notably sulky, complaining and causing a disturbance.

Within the story, Ibuse plays a critical role as part of the command and support structure for the Coppelion operatives in the field. He is typically stationed away from the front lines, working from a base of operations where he helps coordinate rescue efforts and provides crucial information and encouragement to the teams navigating the dangerous environment. When the situation escalates, he is not afraid to take direct action, as seen when he and Vice Principal Mishima commandeered a rescue helicopter to save those trapped on a train. His authority within the team is significant; he is respected by the members of the 3rd Division and possesses the ability to unite everyone under his command without resistance.

The key relationships in Ibuse's life center around his military and Coppelion colleagues. His connection to Onihei Mishima is the most professionally significant. He is almost always seen by Mishima's side, sharing the same values and beliefs, though there is a clear difference in maturity between the composed commander and his more volatile subordinate. Ibuse clearly respects Mishima and follows his lead, even when his own instincts push him toward confrontation, as Mishima is often the one to rein him in. Outside of this professional bond, he shares a notably close personal friendship with Aoi Fukasaku. This intimacy is highlighted by the unique way they address each other; Aoi adds the affectionate suffix "cchi" to the end of his name, a sign of close friendship that Ibuse tolerates without complaint. In a moment that underscores their bond, Ibuse took the time to lecture Aoi while simultaneously reassuring her that he and the 3rd Division were on their way to save her and the others, demonstrating a blend of big-brotherly concern and steadfast support.

Regarding character development, Ibuse shows a progression from a primarily calm and supportive background figure to someone whose more flawed and emotional nature emerges under pressure. His hotheadedness and childish tendencies become more visible as the narrative continues, suggesting that the stresses of the mission and the injustices he witnesses chip away at his professional composure. However, this does not erase his underlying sense of responsibility; rather, it reveals a character struggling to balance his duty as a military officer with his personal feelings of loyalty and frustration.

In terms of notable abilities, beyond his tactical and leadership skills, Ibuse is noted to carry and be proficient with a katana, a traditional Japanese blade, which he uses as his primary weapon. This ability with a melee weapon in a setting defined by environmental hazards and advanced technology suggests a more traditional and personal approach to combat.
