Ranpo Edogawa
"This'll be easy for the world's greatest master detective. I mean, the Armed Detective Agency was founded for the sole purpose of harnessing your talents, Ranpo-san… And inviting me into the Agency is… something I'm always… thankful for…"

- Yosano's supposed parting words to Ranpo

Yosano was recruited by Ranpo into the Agency three years after the end of the Great War. At that time, the traumatized Yosano did not wish to use her healing ability anymore and claimed that it made the cost of people's lives cheap, but Ranpo suggested her not to use her ability, reasoning that he shall be the one to stand out in the Agency, and instead asked her to join the Agency where she could use her kindness. This eventually persuaded Yosano to enter the Agency, a feat that Yosano becomes thankful for until her later years.

As a result of their shared past, Yosano apparently has a close relationship with Ranpo, whom she respects as the Agency's master detective and the greatest detective in the world. Hence, she has great trust in Ranpo's prowess, despite knowing and more so because she knows that he is not an ability user. When Edgar Allan Poe trapped the both of them into Tragedy Manor via his ability, because of Ranpo's initial oblivion that he does not possess an ability, Yosano carefully chooses her words in encouraging Ranpo to do his "usual thing" of deduction even without his glasses, so as not to rub him off the wrong way and to avoid rashly revealing that he does not possess an ability.

Later, when Yosano was attacked in Poe's novel, Ranpo showed great concern towards her, while Yosano placed her utmost trust in him to solve the case as the linchpin of the Agency. In her supposed dying words, Yosano also voiced her gratitude to him for recruiting her in the Agency. Her "death" eventually gave Ranpo the pivot into solving the case by "using" Yosano's glasses, which ultimately led to their escape back into reality. She then attempted to unveil that Ranpo must be a normal person with exemplary deduction skills, though Ranpo once more asserts that he is an ability user, leaving Yosano to merely chuckle at his retort.

During casual times and even during respites at war, Yosano and Ranpo share a friendly rapport. When Ranpo asked Yosano to play with him, she interestedly accepted his invitation and even asked for what stakes they were to play. Furthermore, Yosano's mature and calm disposition would complement rather than clash with Ranpo's childlike outbursts; while Ranpo once complained out of boredom that he wished to go out during the Guild war, Yosano calmly warned him that the Mafia or the Guild might only lop his head off. Nonetheless, Yosano understands Ranpo's devastation when Fukuzawa is placed in grave danger, especially due to the Cannibalism virus and became worried for Ranpo as well.

Yukichi Fukuzawa
Together with Ranpo, Fukuzawa is one of the first people whom Yosano knew in the Agency, as Fukuzawa was the one who fought for Yosano and ensured that she would never get dragged to Mori's scheme once more. Yosano also indicated that the President and Ranpo knew of her "sins" back then and have long forgiven her for them. As such, Yosano is likely very grateful to the President's intervention and for welcoming her into the Agency.

As such, like the other Agency members, Yosano became deeply concerned when the President became afflicted with the Cannibalism virus. Hence, despite being ordered explicitly by Fukuzawa himself not to fight the Mafia, Yosano still willingly participated in taking on the Mafia for the sake of protecting him.

Due to their shared history, Yosano also knows the President's character quite well. In one instance prior the outbreak of the Guild war, she aptly deduced that the President was apparently riled up when the relatively new Atsushi Nakajima thought that the President seemed like his usual self due to his typical demeanor.

On a deeper level, Yosano knows that the President would never allow anyone in the Agency to be transferred to the Port Mafia under normal circumstances. However, due to Mori's disinformation, Yosano was overcome with horror when Mori said that Fukuzawa "allowed" him to take her, despite the President specifically asking him not to choose her. Against all odds, however, Yosano remained steadfast and loyal in the Agency and by extension to the President after they have reunited once more to take on the Decay of Angels.

Doppo Kunikida
Kunikida is one of Yosano's first subordinates in the Agency, as he presumably entered the organization sometime after Yosano. Though Kunikida is sometimes visibly frightened towards Yosano for her healing treatments, Yosano would in turn frequently jest how Kunikida and the others are such a "worthless bunch", retorting that they might already be six feet under if it were not for her healing ability. Nonetheless, they have a friendly relationship, with Yosano sometimes asking Kunikida to go shopping with her and even to drink with her during Kyōka Izumi's entrance exam party.

Having known Kunikida throughout the years, Yosano is also well-acquainted with his weapons and tactics of choice. For instance, Yosano is quite familiar with Kunikida's stun grenade. At one point, Kunikida used this to his advantage and his knowledge of Yosano's schedule for that day, which eventually led to Yosano's convenient arrival to heal Kunikida and Aya Koda following a grenade explosion.

As co-workers in the Agency, Yosano holds a high amount of regard for Kunikida and would ask him as the Agency's occasional interim director on what they shall do during times of Fukuzawa's incapacitation or absence. As a result, Yosano and the others would readily agree to his sensible plans for the team. Likewise, Kunikida recognizes Yosano as a vital part of the Agency who fully completes their organization.

In the anime, after the Black Lizard raids the Agency office, Yosano made sure to remind Kunikida that it was now his turn to give the neighborhood apologies and reconciliatory gifts, much to his chagrin.

Osamu Dazai
Yosano has a professional relationship with Dazai. They also both seem to agree that "death is the fairest judge of all". Quite notably, Yosano's healing ability does not work on Dazai because of his nullification ability. As a result, the Agency has prepared a special procedure for Dazai in case of emergency: should his heart stop beating, they are to immediately resuscitate him, which brings him from being dead to being on the brink of death. Before Dazai's brain re-functions and ability reactivates, Yosano is to use her healing ability on him within 0.5 second.

Kenji Miyazawa
Yosano and Kenji appear to get along well in the Agency, and they seem to complement each other during combat, given Yosano's healing ability and fighting prowess and Kenji's super strength. As such, they have worked together in facing Chūya Nakahara during the Guild war and on another occasion against the Mafia together with Jun'ichirō Tanizaki.

As with the other Agency members, Yosano becomes concerned for the welfare of Kenji. This is evident when Kenji gets stabbed twice while on the run from the Hunting Dogs during the Agency frameup. In turn, however, Kenji assures her that he shall be alright, possibly placing his trust in her to heal him.

Jun'ichirō Tanizaki
Though Yosano appears to be in healthy terms with Tanizaki, the latter is quite fearful towards Yosano for her treatments like the other Agency members. Furthermore, he also advises Atsushi, then a rookie member, not to get hurt no matter what happens, implying the torturous treatment he has to undergo by then. Nevertheless, Yosano and Tanizaki share a professional relationship in times of serious cases, as with their other Agency members, especially when they agreed to fight the Mafia despite Fukuzawa's forbiddance to do so.

Moreover, when Tanizaki volunteers to take Yosano's place in potentially being transferred to the Mafia, Yosano prevents him from doing so for her sake. In return, she narrates her personal story with Tanizaki and Kenji about her past with Mori and how she was ultimately recruited into the Agency.

Atsushi Nakajima
After Atsushi passes his entrance exam, Yosano forms a rather harmonious relationship with him, comfortable enough to ask him to accompany her shopping even when she meets him only for the first time. Along the way, Yosano takes interest in Atsushi's ability, specifically in his regeneration. Moreover, she promptly provides him some advice as a senior member of the Agency and even works with him on the spot after an ambush attack by Motojirō Kajii.

Through time, Yosano has grown to trust Atsushi as a valued comrade. During the Agency's frameup, Yosano places her utmost trust in Atsushi's plan which he created with Francis Scott Key Fitzgerald, despite the other Mafia members being wary of Fitzgerald. As she explained, Atsushi fought the man to the death aboard Moby Dick; as such, those like Atsushi who have exposed their souls for survival cannot be easily deceived.

Kyōka Izumi
Like the other Agency members, Yosano was quite fond of Kyōka when she first arrived in the Agency. When Kyōka later officially passed her entrance exam, Yosano looked proud of her achievement together with Atsushi's that ultimately saved Yokohama. As with any Agency member, Yosano does not hesitate to treat her co-members when wounded, which naturally includes Kyōka.

Notably, other media portray Yosano to be like a motherly figure towards Kyōka, which the latter is also apparently grateful for.

Ōgai Mori
Near the end of the Great War, the 11-year-old Yosano served as the assistant of Mori and as a student surgeon alongside him when she was drafted by Mori from a candy shop. Towards the final moments of the war, Yosano was emotionally abused by Mori during her time working with him as a doctor, including forcing her to heal a soldier after shooting him to make his condition near death in order for Yosano to heal him.

After the Great War, Yosano was incarcerated and became apathetic. Three years later, Mori found her in confinement and tried to get her to work if him again. Mori's then friend, Fukuzawa, was against this, as he felt compassion for Yosano, knowing she wasn't fond of him after her experience working and being abused by Mori during the Great War.

This disagreement caused Fukuzawa and Mori to fight in front of Yosano as she sat in a wheelchair; after this, Fukuzawa and Mori became enemies, and Yosano felt it was her doing that caused a rift between the Agency and the Mafia. Until her adulthood, Yosano shows great fear and resentment to Mori. When she found out that a member of the Agency would be transferred into the Mafia as part of a deal with Fukuzawa, Yosano immediately froze in fear after yelling at Mori for trying to get her once more to his organization.

Michizō Tachihara
"To get revenge…? You went that far… Then do what you want."

- Yosano urges Tachihara to avenge his brother

As part of naturally opposing organizations, Yosano and Tachihara eventually worked together during the Agency frameup, specifically with the Black Lizard in taking cover from the military police and the Hunting Dogs. Yosano initially asked Tachihara and Gin Akutagawa to leave her alone in escaping to prevent them from getting further involved, but Tachihara demanded her not to belittle the Mafia.

Along the way, Yosano learned about Tachihara's excellent older brother, whom he hated being compared to. This compelled him to tread the path of a delinquent, in which he claimed that orders make him. Soon after, Yosano and the others were ambushed by a hooded figure, which she soon unveiled to be a mannequin being manipulated all along by Tachihara, the fifth Hunting Dog and younger brother of the Soldier from Yosano's past.

On the surface, Tachihara blamed Yosano for his brother's death, having carried a grudge towards Yosano. As he finally cornered her to take his vengeance for his brother, Yosano freely accepted her end at Tachihara's hands, before Tachihara retracted his action. With this, Yosano apologized to Tachihara for what happened to his brother in the past.

Motojirō Kajii
"You think death lies at the apex of science…? Bull! Anyone with such little regard for life will die by my hand!"

- Yosano rebukes Motojirō's perception towards death

Yosano came into contact with the Mafia bomber Motojirō during the hunt for Atsushi. As the two clashed, their opinions towards death also opposed each other, with Motojirō having been conducting experiments involving actual people to find out what "death" is. As a doctor, Yosano greatly found this offensive and, after insulting the scholar as an idiot, rebuked his little regard for human life. As such, Yosano vented her rage towards him, alongside getting needed intel from the mafioso at the time.

Sometime during the affliction of both Fukuzawa and Mori with the Cannibalism virus, Yosano met with Motojirō once more in battle. From their previous encounter, Yosano had knowledge of Motojirō's antics and signature combat style, being wary of his odd approach at the time. After this encounter, Yosano retained her view towards and continued to refer to Motojirō as an "idiot", more than likely illustrating the same amount of contempt she had towards the man.

Ryūrō Hirotsu
Similar with Tachihara and Gin, Hirotsu was one of Yosano's natural adversaries as part of opposing organizations. Nevertheless, they worked briefly together on Mori's orders to help the Agency flee from the military police and the Hunting Dogs. As such, Yosano felt a sense of regret towards Hirotsu after witnessing the bloody attack on him to help her and the other Black Lizard commanders to escape. Hence, she attempted to make Tachihara and Gin escape to prevent anyone else dying for her sake, albeit to no avail.

Gin Akutagawa
Yosano also worked with Gin and other mafiosi during the encounter with the military police and the Hunting Dogs, despite being initial adversaries due to rival organizations. When Yosano was almost attacked by the hooded figure, Gin immediately came to her rescue, wounding Gin.

As Yosano escaped with Gin and Tachihara, she asked them to leave her behind and escape to prevent them from further getting hurt like what happened with Hirotsu, but the two refused and continued to help her until they got ambushed themselves.

Chūya Nakahara
"A tempting offer, for sure. But we've got an even better one. First, I'll sever all four of your limbs and make you spit out your scheme!"

- Yosano engages Chūya in a fight

During the three-way conflict, Yosano and Kenji worked together to face Chūya, who had been sent as a Mafia envoy in luring the Agency to clash with the Guild. To give Fukuzawa and Ranpo time to deliberate on Chūya's offer, Yosano engaged Chūya in a fight with Kenji, threatening to hack off his limbs and divulge the Mafia's hidden plot. Shortly after, Yosano recognized Chūya as the gravity manipulator and, as he stood on the ceiling upside down, reprimanded him to come down at once. Yosano then became visibly perturbed towards him when Chūya went down and decimated the ground, displaying his overwhelming strength.

Later on, Chūya aided the Agency during their run from the Hunting Dogs as ordered by Mori. His appearance saved Yosano's life, which ultimately led the Agency to briefly take refuge in one of the Mafia's hideouts.

The Soldier
This soldier was one of Yosano's patients during the Great War, having met him for the first time after she healed him and others. On their first encounter, Yosano lightly scolded him for reading a novel right after having recovered from near-death. She then coldly let on how he did not seem thankful for her nor brave enough to head back to the frontlines, though the Soldier admitted his gratitude. Hence, he gave her a golden butterfly pin and thanked her as "Miss Angel", flustering the young Yosano.

Throughout the war, Yosano and the Soldier shared an amicable relationship. During the few instances of respite, Yosano questioned the relevance of her ability and how it seemed to only exacerbate the soldiers' trauma rather than heal them. Hence, at one point, the Soldier encouraged her with gentle words on how she saved him many times and gave him a sense of hope to return to his family once the war ended. Yosano then seemingly found a friend in the Soldier and stutteringly thanked him.

As the war raged on, Yosano found the Soldier heavily injured, whom she found to be in an unhinged state. To prevent him from heading back to the frontlines, Yosano angrily defied Mori's order to heal him, causing the latter to shoot him near death to force Yosano into healing him.

Later, Yosano was confronted indirectly by the Soldier that she was an "Angel of Death" who controlled the battlefield and confessed that her correctness taught him of everyone's limit. She then rushed to see him, only to find him having committed suicide and a note stating that she was "too correct". This broke and further traumatized Yosano, possibly leading to her attempt to sink their ship.

Yosano would treat and hold her given butterfly pin in utter care, having attempted to find it when she happened to lose it during the war. At least three years later, Yosano became enlivened once more when Ranpo found her lost butterfly pin, returning the remaining memento she had of the Soldier back to her. Until her adulthood, Yosano continues to wear her hairpin in her typical uniform.

The Soldier's death would continue to haunt Yosano several years later, when she suspiciously tried to make a connection with the Soldier and the hooded figure who apparently had his, his relation to a military corps, and an ability to manipulate swords during the Agency hunt by the Hunting Dogs. Despite having confirmed his death back then, Yosano steeled herself to confront the ghost of the past who had seemingly come for her, eventually accepting to accept her punishment and help the Agency. All the pieces would then be revealed; the Soldier turned out to be Tachihara's brother, and that Tachihara had come to avenge him. In the end, when he spared Yosano, she was apologetic to him for what happened to the Soldier.

Katai Tayama
Katai is Yosano's former co-member in the Agency. Hence, Yosano knows that Katai is Kunikida's closest friend, and she also appeared to lament upon hearing that Katai had been "killed".

Sometime in the past, Kunikida asked for Yosano's advice on a good "date" venue for Katai and a thankful client. Yosano suggested booking a European-style café and scolded Kunikida not to schedule it during nighttime, since it was their "first time meeting".
