Kyōka Izumi/Relationships

Atsushi Nakajima
Atsushi first encounters Kyoka when he assisted Yosano in shopping. He later finds out that Kyoka has killed 35 people and wants to stop killing others, he then saves her from the bomb explosion. As someone who understands what she has gone through, Atsushi deeply cares about Kyoka as to accompanying her when they explored Yokohama. He also tries to protect her when someone tries to hurt her.

Yukichi Fukuzawa
Fukuzawa is fully aware of Kyoka's murder count and initially had no intention on letting her become a member of the Armed Detective Agency. However, he was easily swayed by Kyoka who looked at him in desperation.

Kōyō Ozaki
Koyo is extremely protective of Kyoka, acting as if she has the role of her mother. She believes that Kyoka's ability is only capable of killing and that she should succumb to the darkness of that reality. However, she is later willing to make a deal with Dazai to ensure Kyouka’s safety and to give her the chance that she herself never had to live a life in the light, showing that Kouyou does care about Kyouka and her happiness.

After Kyouka's first mission in the Armed Detective Agency, Kouyou steals classified files about Kyouka's parents as a gift for her, relieved to see that Kyouka is happy in the Agency and proud of her.

Kyoka's opinion on Koyo is extremely vague, but she is willing to go against her in order to protect Atsushi. Because of this, Koyo carries a grudge against the weretiger for influencing Kyoka.

Ryunosuke Akutagawa
Kyoka has had a hostile relationship with Akutagawa. The mafioso believed that Kyoka served no other purpose in life but to kill, and that's all she is capable of. Due the influence of Atsushi, Kyoka eventually stood up against Akutagawa, knowing her potential fate for doing so, but was saved by the agency member just in time. Kyoka later became determined to work hard to prove to herself that Akutagawa’s beliefs about her were wrong and that she could do more than just kill.

During the Cannibalism Arc, Kyoka crosses paths with Akutagawa yet again, fighting for their respective leaders. During the initial stages of their battle, Akutagawa still believed Kyōka was not fit to be with the Detective Agency and fought to test her combat skills. Filled with determination to prove him wrong, Kyōka cornered Akutagawa and filled with bitterness and vengeance towards his low views of her, attempted to assassinate him as she bid him farewell. However, Akutagawa stopped her and after seeing the life in her eyes, told her she had changed from their first encounter in which he saw the same eyes in her that he once he himself; eyes that had a desire to die. He told Kyōka even up to the end of the Guild arc, she constantly partook in actions that showed she had no values in her life, something he understood well. Recognizing that Kyōka was no longer suicidal and found meaning to her life, he stated his happiness for her which greatly shocked her and caused her to start reconsidering her views of Akutagawa.
