Doppo Kunikida

Kunikida is a tall and slim young man with deep, green-grey eyes. His bangs were parted to the right and he had rather neat, but spiky golden-blond hair that ends in a long ponytail. He was 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 was 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 came off as somewhat strict and harsh during investigations.

He was also practical to a fault, as he almost considered abandoning a kidnapped Atsushi Nakajima, because the boy's presence might implicate the Agency. He also once advised Atsushi to give up on the wanted Kyōka Izumi, lest his one-man boat might sink the both of them if he saves her, though he soon encourages Atsushi later on when the latter shows resolve to rescue her. Despite this, Kunikida was nonetheless a trustworthy and loyal detective upon whom many in the Agency relyed on because of his authoritative capability and responsible nature, which is why he was deemed as the Agency's next-in-line to becoming its President.

He was 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 was also known for his exasperated outbursts, which are primarily caused by his partner, Osamu Dazai, who constantly vexed him with his 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. Kunikida extended similar faith to Ranpo Edogawa, as Kunikida actively participated in letting Ranpo believe Super Deduction is a real ability, since Kunikida, like the rest of his comrades, respected Ranpo's detective prowess and its value to the Agency.

Kunikida's ability, The Matchless Poet. allowed 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 was 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
