Kunikida Doppo

Kunikida is a 22 year old young man, tall and slim with deep, green-grey eyes. His bangs is parted to the right and he had rather neat, but spiky golden-blond hair that ends in a long ponytail. He is always seen wearing his glasses.

His attire consisted of a beige vest over a black long-sleeved dress shirt, a red ribbon tied into a bow around the collar, beige pants, and plain brown shoes.

As a member of the Armed Detective Agency, Kunikida is very professional and diligent when it came to his job, because to him, the reputation of the agency takes precedence over anything else. He constantly felt the need to organize, gather, and schedule everything, which is why he comes off as somewhat strict and harsh during investigations.

He is also practical to a fault. Despite this, Kunikida is nonetheless a trustworthy and loyal detective upon whom many in the Agency relied on because of his authoritative capability and responsible nature, which is why he is deemed as the Agency's next-in-line to becoming its President.

He is almost never seen without his trademark notebook, which he believed to be an "ideal" and guide to life. He utilized it for several reasons, such as data-gathering, planning, making the world a better place, and most importantly, a medium for his ability, The Matchless Poet.

Though he often appeared calm and careful, Kunikida is also known for his exasperated outbursts, which are primarily caused by his partner, Osamu Dazai, who constantly vexed him with his comical suicidal attempts. However, Kunikida never genuinely disliked Dazai. He acknowledged Dazai's skill and knowledge when first working with him, and he entrusted much of the Agency's strategies to Dazai.

Despite his well-rounded maturity level, Kunikida was also somewhat naïve and prone to easily believe lies, including the "merit" of a noose when it comes to improving neck strength and that extreme shouting can cause hemorrhoids, which he later jots down in his notebook for future reference.

Kunikida valued human life, as he strived to save all innocent people during dangerous events in Yokohama. He stuck to this belief after seeing young people injured or killed in front of him. As a result, Kunikida never thought killing his opponents is the only option, and constantly looked to solve problems without bloodshed. Due to Kunikida's passion to try to protect the city and its people, his colleagues believe he is the strongest and most virtuous person in the Agency.

The Matchless Poet, his ability, allows Kunikida to make objects written on the papers of his notebook come into existence. However, it does not work on objects larger than the notebook. Such objects include wire guns, handguns, grenades, and flashbangs.

He is shown to be able to use pre-written notes as a means for his object summons, which can be especially convenient if one of his hands is bound and incapacitated. Also, he was able to remotely activate his ability, transforming pre-written notes into objects, which come in handy when supporting other members from afar

Before working for the Agency, he was a math teacher in an Academy.

He is also shown to be skilled in martial arts. Kunikida has 58 conditions for an ideal partner, which spans eight pages and 15 topics written on the section titled "Spouse" in his notebook. His likes are his notebook, fishing, and seared tataki bonito.
