Ōgai Mori
"But sad to say, I need to help our unreliable boss get this organization back in order."

- Kōyō affirms her loyalty to Mori in the Mafia

Kōyō and Mori have a harmonious professional relationship as fellow higher-ups in the Port Mafia. For instance, they once spent time with each other amidst the falling cherry blossom petals. While Mori perceives Kōyō an indispensable, strong, and proficient individual, Kōyō teasingly views Mori as an "unreliable boss" whom she must help in stitching back the Mafia in order. Nonetheless, she professes her loyalty to him as the current Mafia boss quite different from his predecessor whom she held a grudge on, and she trusts Mori's judgment as Mafia boss ever since Osamu Dazai's and Chūya Nakahara's entrance in the Mafia.

Though Kōyō opts to speak to Mori blatantly at times, for example once dryly threatening to "sew his mouth shut", she retains a formal rapport with him and appears to hold respect for him behind his back. In addition, during Mori's virus affliction, Kōyō personally guarded his chamber and almost killed Jun'ichirō Tanizaki, despite not wanting to cut down one of Kyōka Izumi's colleagues, for the sake of protecting Mori.

Chūya Nakahara
"We'll cross that bridge if we need to. If the boat is so easily tipped over, the best course of action would be to destroy it now in a blaze of glory."

- Kōyō advises Chūya en route to one of his first Mafia meeting attendances

Kōyō was tasked to oversee Chūya upon his entrance in the Mafia. As Chūya usually called her ane-san (姐さん,), Kōyō didn't prefer it initially, though she would later accept it over time. Kōyō once brought the newcomer Chūya to a meeting for him to gain experience, advising him how their guest was important to the Mafia albeit expendable should they display hints of aggression to anyone like Chūya. Furthermore, Kōyō voiced out her concern to Mori about having Chūya and Dazai work together in the Mafia after seeing their mutual disapproval towards each other, to which Mori ambiguously responded as a seeming test to figure out whether "only a diamond can polish another diamond".

Eventually, as Chūya rose in the ranks as Mafia executive like Kōyō, they appear to have mutual respect and professionalism towards each other, occasionally seen working together personally. For instance, Kōyō and Chūya were both informed of the Cannibalism virus that plagued both Mori and Armed Detective Agency president Yukichi Fukuzawa, making them deliberate on the optimal solution. While Chūya immediately displayed willingness to crush the Agency, Kōyō showed reluctance in playing right into the enemy's hands, albeit ultimately having no choice but to wage war on the Agency.

Ace
"My, someone's excited! Were you not the first in the shelter during the Guild war?"

- Kōyō insults Ace

Port Mafia's Previous Boss
"I rather like it here now. My grudge was with the previous boss."

- Kōyō's preference in the present Mafia compared to its previous iteration

Kyōka Izumi
"Listen to me, Kyōka. I know how you feel. But… some things are simply impossible. No matter how much a natural-born assassin like you seeks light… A flower that blooms in the dark can survive only within the dark. If you pursue the light, its heat will burn you up in the end."

- Kōyō tries to empathize with Kyōka

Kōyō is very protective of Kyōka, having taken a liking to her due to their similar abilities and seems to see her past self in her, acting as a maternal figure to Kyōka. Initially, she fights to bring Kyōka back to the Mafia, as she strongly believes due to her past that killers like herself and Kyōka can only ever live in darkness. As such, Kōyō is well-aware of Kyōka's natural instincts of harming or killing other people on account of self-preservation, once asserting during their encounter how Kyōka instantly engaged in combat rather than first resorting to negotiation or even coercion and likening her to a demon.

However, Kōyō apparently wishes to genuinely give Kyōka the chance to live a life in the light that she herself never had. Hence, she is later willing to make a deal with Dazai to ensure Kyōka's safety and even asked Atsushi Nakajima, a previous opponent and now the girl's colleague, to look after Kyōka, showing that she cares very much for Kyōka.

Atsushi Nakajima
"Before long, in this war, Kyōka will kill a great number of people. Once she does, she'll never be able to live 'in the light,' as she desires. Just as I once wished for. Child, I leave Kyōka in your hands."

- Kōyō entrusts Kyōka to Atsushi

Osamu Dazai
"Have you forgotten the rules of the Mafia, boy? Blabbing would be a death sentence."

- Kōyō refuses to divulge Mafia intel to Dazai

Kōyō's Admiree
"He said that he'd show me the brilliance of the outside world."

- Kōyō recounts her beloved's promise
