Kyōka Izumi/Relationships

Kyōka was given a cell phone by her mother days before the latter's demise, which Kyōka treasures and always keeps with her as a memento of her mother, even after she joined and later defected from the Port Mafia and after she gains considerable control over Demon Snow. Though Kyōka initially despised Demon Snow for slaying her mother and her father, Kyōka admits that she did not actually wish to hate it. In a vision, Kyōka encounters her mother, who correctly acknowledges Kyōka's desire to use her ability to protect others.

Upon learning that her mother passed down Demon Snow to her in her final moments, Kyōka shed tears and realized how Demon Snow is an embodiment of her parents' love rather than their mere killers, later leaning affectionately on her materialized guardian.

### Friends

#### Atsushi Nakajima

Atsushi first encountered Kyōka when he assisted Akiko Yosano in shopping. He later found out that Kyōka has killed 35 people and wants to stop killing others, compelling her to he then saves her from the bomb explosion. As someone who understands what she has gone through, Atsushi deeply cares about Kyōka and even accompanied her when they explored Yokohama rather than plainly giving her out to the police.

In turn, Kyōka also cherishes Atsushi as a fellow Agency member and is equally protective of him as he is of her. She was willing to summon Demon Snow to protect him from Kōyō Ozaki despite her apparent hatred towards using the ability at the time. She seems to care greatly for Atsushi to the point she would threaten to cut down anyone who was a harm to him, including Francis Scott Key Fitzgerald and even Lucy Maud Montgomery when she was visibly aggressive towards him.

Kyōka also shows her concern towards Atsushi and would occasionally rush at him out of worry, especially after getting trapped from Anne's Room and after the incident in Standard Island. Nevertheless, she is later seen trusting his skills more and letting him fend for himself.

On a deeper level, Kyōka considers Atsushi as the one who showed her the light—her greatest desire—and gave her hope; as such, she became greatly shaken and lost this hope when Atsushi was abducted by Fitzgerald and Herman Melville. Testimony of her concern towards Atsushi, during the Agency frameup, Kyōka did not hesitate to return to the scene of the crime to rescue Atsushi even when she and the others are wanted for terrorism. Doppo Kunikida was initially reluctant to let her go, though he soon allowed her to do so after she resolutely affirmed her wish to help Atsushi. She also trusted Atsushi's option to clinch a deal with Fitzgerald, whom she warned him about being a past enemy.

#### Doppo Kunikida

Kunikida initially acted coldly towards Kyōka, preferring not to have her stay in the Agency and even instructing Atsushi to surrender her to the military police. However, he gradually warms up to her, especially when Kyōka passes her entrance exam and saves Yokohama with Atsushi. From then on, Kunikida considers Kyōka as one of his juniors and advises her not to tarnish the Agency's name as one of their own.

During the Agency's escape from the military police, Kyōka asked for Kunikida's permission to head back to the initial hostage situation site to save Atsushi. He warned her of the forensics team that might be lurking and might spot her, but Kyōka did not mind; he then allowed her to do so and gave her a page of his notebook written with glue and putty for their use in case of emergency.

#### Yukichi Fukuzawa

Fukuzawa is fully aware of Kyōka's murder count and initially had no intention on letting her become a member of the Armed Detective Agency. However, Kyōka looked and pleaded at him in desperation to have her stay in the Agency, compelling the President to hire her on the spot. Kyōka also played along with Fukuzawa for claiming that she is his granddaughter when Minoura suspected her, making the officer notice how the two are quite alike.

Kyōka later joined in the fight against the Mafia to save the afflicted President in the process, despite her fear towards Ōgai Mori and provided her knowledge of the Mafia to her fellow Agency members.

#### Osamu Dazai

Kyōka first encountered Dazai along the streets as part of her mission to abduct him to the Mafia base, which she succeeded in doing. Eventually, the two seemed to get along well, with Kyōka agreeing to Dazai's arrangement to let her stay in Atsushi's room. He even asked him to look after Kyōka from assassins that might be after her life for betraying the Mafia.

Later on, when Dazai tried to rescue Kyōka from her aerial confinement, Kyōka asked him to give up on her, but Dazai persisted on persuading her on how he believed in her potential to save others despite being an ex-hitman, similar to an old friend, and how Atsushi passed being an Agency member against all odds. As such, Kyōka eventually had a change of heart and decided to sacrifice her life to save others, which ultimately ended in Kyōka passing her entrance exam.

#### Kōyō Ozaki

Though Kōyō is extremely protective of Kyōka, Kyōka's opinion on Kōyō appears extremely vague. However, she is willing to go against her in order to protect Atsushi, and Kyōka firmly disagrees with Kōyō's opinion that she is a "flower of darkness". In this regard, Kōyō was forced to kill Atsushi to pay for "blinding" Kyōka with the light; hence, Kyōka tricked Kōyō into attempting to kill her without letting her on with murderous intent and summoning Demon Snow to spar with Kōyō's Golden Demon.

Nevertheless, Kyōka tended to realize her dark nature due to Kōyō's words, who told her how Kyōka kills someone in her way without coercion or negotiation during their brief clash. Kyōka remained persistent in defying Kōyō and going back with her, though she almost succeeded in returning to the Mafia once Kōyō revealed to Atsushi how Demon Snow killed her parents.

As the series progresses, Kyōka begins to feel a mutual perspective towards her, with the two forming a mother-daughter bond.

#### Ryunosuke Akutagawa

During her time in the Mafia, Kyōka recognized Akutagawa's power and once sought him to kill Demon Snow and herself during her time in the Mafia. Though it was unknown how this event unfolded, Kyōka and Akutagawa turned to have a hostile relationship. The mafioso believed that Kyōka served no other purpose in life but to kill and urged her to stop breathing otherwise. As a result, Kyōka carried out assassinations as ordered by Akutagawa by controlling Demon Snow through her phone, which she wished never to do again.

Due the influence of Atsushi, Kyōka eventually stood up against Akutagawa, knowing her potential fate for doing so, but was saved by the Agency member just in time. Kyōka 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 events of Cannibalism, Kyōka crossed paths with Akutagawa yet again, fighting for their respective leaders. Initially, Akutagawa still believed Kyōka was not fit to be with the 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 kill him. Eventually, Akutagawa told her how he grew glad for her change, shocking Kyōka and causing her to reconsider her views towards him.

#### Ichiyō Higuchi

It is unknown whether Kyōka and Higuchi worked together in the Mafia under Akutagawa's command, but Higuchi appears to be well-aware of Kyōka being the Mafia's former assassin. Meanwhile, Kyōka seems indifferent towards Higuchi and threatened to cut off her arm if she did not divulge the information on the virus-stricken boss' sickroom passcode. When Higuchi avowed her utter loyalty to the Mafia, Kyōka seemed to almost carry out her threat, though she was unable to due to Akutagawa's arrival.

#### Ōgai Mori

Kyōka appears to have considerable knowledge of the Mafia boss and has shown terror towards him when she saw him in casual clothing with Atsushi. She later further described him to be fearsome, though she came to conquer such fear in exchange for helping the Agency fight for Fukuzawa's sake and protection.

#### Lucy Maud Montgomery

Kyōka and Lucy have mutual mistrust at each other, with Kyōka subtly assuring Atsushi that she shall reap out first those who come at them, though she highly pertains to Lucy who had been aggressive to Atsushi. Lucy asserted that she did not need Kyōka's trust, so the latter questioned whose trust she needed, albeit appearing indifferent all the same. Kyōka also blatantly described Lucy's coffee to be "average" when Atsushi thought it tasted great, adding that it tasted far from the manager's coffee and predicted the customers' uproar if she sold it for the same price as the manager's.

Nevertheless, Kyōka and Lucy worked together alongside Atsushi and Ango Sakaguchi during their Sky Casino operation as part of Dazai's plan. Kyōka still retained some initial apathy towards Lucy amidst her concern for Atsushi (which she tried to hide and stop Ango from revealing), though they later seemed to share some moments of understanding. Lucy tried to console Kyōka and Atsushi after they heard the Decay of the Angel' plan and later urged Kyōka to celebrate with the other Agency members upon getting reunited, though Kyōka told her that she was controlling herself.

#### Mushitarō Oguri

When Kyōka and Atsushi set out to break Mushitarō out of confinement in a government bank, Mushitarō was unwilling to cooperate out of personal reasons. This compelled Kyōka to bring up the word "manuscript" as a sort of blackmail to have him go with them. Along the way, Mushitarō planned on exposing the two detectives by putting on an act, though Kyōka easily saw through his charade and scared him off with threats and her blade. However, Mushitarō soon agreed to escape the government bank once sighting Ango and used his ability to help Kyōka and Atsushi escape with him.

Once identifying who their allies were, Kyōka, Atsushi, and Ango asked Mushitarō to divulge all that he knew about the Decay of the Angel, but he was reluctant. Kyōka soon bowed and respectfully asked for his information, which apparently compelled Mushitarō to entertain their questions about the organization.
