Koutaro Hattori

Koutaro Hattori is a member of the Returnee Response Division who acts as the liaison between the Japanese Government and the Returnees.

Appearance
Koutaro is a middle-aged man with no distinguishable traits. He is usually seen in a disheveled state, with his hair unkept and outfit messy and stained.

Personality
Koutaro appears to be good-natured and lax at first glance, but he is very sharp to the point that Hajime and the others know not to underestimate him. He is actually well connected within the Japanese government and could mobilize various agencies without having to deal with all of the bureaucracy associated with it.

Koutaro complains at having to endure such hardships in his job while claiming that he is a mere public servant, but takes pride in carrying out his objectives.

Due to the stressful nature of his work, Koutaro tries to find joy wherever he can as a coping mechanism, even when faced with a life or death situation. Even so, he still maintains a high level of competency while doing his work. Another source of his stress is the growing distance with his family due to the secret nature of his work.

Koutaro can be merciless when confronting his enemies. When he interrogates someone that presents a threat to Japan, his methods to extract information out of them can border on torture.

Koutaro is also a bit of an otaku, as he is a huge fan of the franchise, and often uses the names of various mobiles suits for him and his subordinate as codename when they are on secret missions.

Chronology
When Liliana was targeted by various foreign government black ops units due to her aid network's influence, Koutaro attempted to intercept them before Hajime could. Unfortunately, they arrive to the point where Hajime had to intervene. Koutaro then met up with Hajime and apologized for his failure to stop the incident and offered to temporarily relocate his family to a government-owned safe house to which Hajime accepted. Later, Koutaro and his team kept surveillance at the safe house until all of the foreign agents were killed by the Fleur Knights.

Hajime Nagumo
Koutaro has been in contact with Hajime for a few years as part of his job, which is impressive by most standards since his predecessor could not even handle his job for three months. He is extremely scared of Hajime and always takes stomach medication at even the slightest gesture that is made by the demon lord. Nevertheless, Koutaro is vehemently against his daughter Reina seeking to be in a relationship with Hajime.

Kousuke Endou
Koutaro is well-acquainted with Kousuke due to his role as liaison to the Returnees. Unlike his relationship with Hajime, Koutaro is more laid-back and mischievous in his interactions with Kousuke, and is not afraid to tease him at times.

Reina Hattori
Koutaro has a strained relationship with his daughter. She deeply resents him for having been absent throughout much of her life due to his work, but she unaware of her father's true job. After getting a first-hand look at how serious her father does his job, she begins to see him in a new light, but is still hostile towards him. Despite her harsh treatment of him, Koutaro loves his daughter and is willing to support her with her future goals. He also forbids her to be in a relationship with Hajime.
