kunikida and dazai (and their baby daughter)

Dazai is a mysterious person, his true intentions are never revealed unless he himself reveals them. Dazai is usually called lazy as Kunikida always scolds him for being unproductive and slacking off. ​Nonetheless, he's quick on his feet, cocky at times, smart, clever and decisive. Aside from his quick thinking Dazai is the comic relief in the manga and at times Dazai's soft side can be seen, he also has caring side.

​In most occasions, Dazai is overly dramatic, he takes most of his actions as a joke, and although they are very thought out plans he does not credit himself for most of what he has done.

​Eventhough Dazai sounded unearthly, he has no embarrasses with his hobby; as suicidal freak, he's also trying to recruiting beauty to commit double suicide with him after meet Higuchi. He is lazy-ass with almost zero motivation, only while he awake or sleep he always is looking for a method of suicide. Yet he doesn't want the painful way to death.

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

His attire consists 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 comes to his job, because to him, the reputation of the agency takes precedence over anything else.[8][9] He constantly feels the need to organize, gather, and schedule everything,[1] which is why he may come off as somewhat strict and harsh during investigations.

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

He is almost never seen without his trademark notebook, which he believes to be an "ideal" and guide to life. He utilizes 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

Kunikida's typical annoyance towards Dazai. Though he often appears calm and careful, Kunikida is also known for his exasperated outbursts, which are primarily caused by his partner, Osamu Dazai, who constantly vexes him with his suicidal attempts. However, Kunikida does not genuinely dislike Dazai. He acknowledges Dazai's skill and knowledge when first working with him, and he continues to entrust much of the Agency's strategies to Dazai. Kunikida extends similar faith to Ranpo Edogawa, as Kunikida actively participates in letting Ranpo believe Super Deduction is a real ability, since Kunikida respects Ranpo's detective prowess and its value to the Agency.

He is also somewhat naïve and prone to easily believe Dazai's lies, including the "merit" of a noose when it comes to improving neck strength[10] and that extreme shouting can cause hemorrhoids, which he later jots down in his notebook for future reference
