Doppo Kunikida

Appearance: Doppo is a tall young man of medium build, with blond hair and eyes of a gray—grassy color. His bangs are directed to the right, and his hairstyle is quite neatly braided into a long ponytail, but still has protruding hair. He always wears glasses.
His clothes consist of a beige vest on a black long-sleeved shirt, a red ribbon tied around the collar, beige trousers and plain brown shoes.
Personality:Doppo appears to be a very serious, but slightly short-tempered young man. He has been documenting events in a notebook all his life. He doesn't recognize anything except his little notebook. Most likely, he is a perfectionist.

As a member of an Armed Detective Agency, Kunikida takes his work very responsibly and seriously, because the reputation of the agency is above all for him. He constantly feels the need to organize, collect and schedule, which may make him seem unnecessarily strict and harsh during investigations.

Portraying a calm and cautious front, Kunikida is also known for his irritated outbursts, which are primarily caused by his partner, Dazai, who constantly annoys him with his suicide attempts.

He is also uncharacteristically naive and tends to easily believe Dazai's lies, which he later writes down in his notebook for future reference.
The past:When Atsushi tried to guess the previous positions of the Agency members, it turned out that Doppo had previously worked as a math teacher.Dazai stole the "Ideal" and showed the standard of the ideal woman, written by Kunikida, Atsushi Nakajima and Sasaki Nobuko, to the girl they saved. They both reacted the same way — they said that this benchmark had gone "a little" far. Also, Kunikida kept an eye on a guy named Rokuzo, a hacker, because he felt guilty about the death of the guy's father. The story is this: when Doppo found out and reported where the famous terrorist, the Azure King, was hiding, five detectives were sent there without special training, since the military.

Kunikida is responsible, determined, and idealistic. He has a notebook in which he writes his plans for every day, and even for his future. Does not offend women. sometimes he can believe in any nonsense.
