The first thing anyone thinks of when they think of Kunikida is his notebook, full of a number of ideals for his life. He is very focused in this manner, and knows exactly what he wants out of life, as well as what it is he believes. Because he is one of the more responsible members of the agency, he is seen as a leader and is able to organize missions efficiently thanks to his familiarity with each of the members of his team.

Kunikida uses his notebook as his guide to life, which can make him seem obsessive and strict at times. However, this chasing of ideals makes Kunikida a focused and driven person overall, one who is able to go with the flow or trust his comrades over his notebook when the occasion calls for it.

Kunikida often works with Dazai, since Dazai is one of the more powerful and cunning members of the agency. Since the two are opposites in many ways, Kunikida can easily fall into Dazai’s lies and as a result, he reacts with more emotion than one might expect from the normally serious man!

Despite this, Kunikida respects Dazai for his abilities to solve conflict without fighting. They work well together, complementing one another in both intelligence and combat style. No matter what Dazai might do, Kunkida trusts him in the end, which makes the two of them the strongest pair by far among the agency.

Kunikida’s ability, Doppo Poet, is activated through the use of words written in his notebook, usually manifesting as weapons like guns or grenades. Though he cannot make objects larger than the pages of the notebook, his ability is still useful in many situations and displays his more creative side in solving problems. He can even use pre-written notes to plan out events in battle, and can activate his ability remotely as well to give his comrades something to use in a fight.

Kunikida does not have a world-changing ability or intelligence off the charts. However, thanks to his levelheadedness in drastic situations and responsible nature, he is called as the next leader of the agency. He has learned from the struggles he has been through, and leads his comrades efficiently in every crisis since he already leads each team meeting for new missions. Of course, he was the obvious choice as a successor to his mentor Yukichi Fukuzawa!

Desiring justice and valuing the sanctity of human lives, Kunikida works hard to follow his ideals by helping the people of Yokohama as much as he can. He is dedicated to his work at the agency but tries to complete every mission with no bloodshed, even when others are killed in front of him. Kunikida is haunted by deaths from those he has tried to save in the past, but he continues to try for justice in the world again and again.
