Shizuku Yaegashi/Relationships

Shuuzou Yaegashi
Shizuku's grandfather and an instructor at their family's dojo. Shizuku have an extremely close bond with her grandfather ever since she was a toddler, when Shuuzou discovered Shizuku's prodigious talent for the Yaegashi-ryu at the age of 4. Because of this, Shizuku did her best to live up to her grandfather's expectations even if it meant suppressing her own desires and feelings. Shizuku also took to heart all of Shuuzou's teachings and values such as treating all disciples of Yaegashi-ryu as foster family regardless of how much trouble they caused or went astray. When her best friend Kaori scolded him for not allowing Shizuku to grow out her hair as a girl, Shuuzou made an exception for Shizuku.

Koichi Yaegashi
Shizuku's father and also an instructor at their family's dojo.

Kirino Yaegashi
Shizuku's mother.

Hajime Nagumo
Shizuku is one of Hajime's classmates that did not harass him, as she is always feeling apologetic towards the behavior of her best friend Kaori that often puts him in trouble. She is devastated when he falls into the Abyss after protecting her and the rest of their classmates from a Behemoth. She also becomes angry towards those who were badmouthing him in the Heiligh Kingdom. At first she does not think much of Hajime besides being the love interest of her best friend Kaori, but after Hajime saves her and Kaori from Cattleya's ambush in the Great Orcus Labyrinth, she feels great gratitude and drastically changes her impression of him.

Shizuku also became deeply impressed with Hajime for being able to survive his fall into the depths of the Great Orcus Labyrinth despite being the weakest, and is also the first to understand that Hajime must have suffered immense hardships that result in his complete change in his personality and Shizuku also knew that Hajime was dead serious in his claim of killing anyone else including his classmates if they dare to cross him and chose to take the warning seriously as she was fearful that the Holy Church and Heiligh Kingdom would send her to kill Hajime for heresy.

Unlike the rest of their classmates, Shizuku could still get along with Hajime with him even giving her one of his masterpieces: a new enchanted Black Blade Katana that better suited her fighting style. She found herself very attracted to Hajime's crimson magic color and overwhelming strength finding it beautiful. Unlike Kouki, Shizuku doesn't condemned Hajime after he murdered Hiyama for his betrayal and murder at Kaori, as she chose to never forgive him for what he have done at both school and Tortus. After he revived Kaori, Shizuku owes Hajime a great debt.

She later starts to develop feelings for Hajime after the Demon Invasion to Heiligh Kingdom's capital and becomes conscious of them during the Haltina Woods Labyrinth Trial. The reason Shizuku falls in love with him is because he is the only person that protects her and see through her strong cover, not expecting her to always be strong and instead expecting her to take care of the others all the time. Despite that, she refuses to acknowledge her feelings because she believes that as proof of betrayal towards Kaori.

In Volume 9, after Hajime saved Shizuku at the Frost Caverns of Schnee Labyrinth from being killed by her doppelganger and also gave Shizuku encouragement to accept her negative feelings that allow her to defeat her copy, it cemented Shizuku's resolve to pursue her love for Hajime. Shizuku flirtatiously request a hand-crafted hairclip type restoration magic Artifact from Hajime as his second present to her after the Black Blade Katana. After that Shizuku peacefully slept on Hajime's back as he carried her, to find the others. After Hajime has easily stopped a corrupt Kouki's rampage without killing him, with gratitude and love, Shizuku affectionately kissed Hajime on the cheek,while also confessing her love for him, and her resolve that she will do anything to become his lover.

After returning to Earth, Shizuku has become one of Hajime's wives and is always happy whenever she's around him. During her wedding photo shoot with Hajime, Shizuku remained by Hajime's side and refused to help her so-called "fans" from the Soul Sisters to get bullied and get completely humiliated by Hajime for their interruption. Unlike most of the other wives, Shizuku still tends to be too shy to openly flirt with Hajime around other people. Hajime usually shows Shizuku sympathy when it comes to dealing with the eccentric behavior of her family.

Kaori Shirasaki
Kaori is Shizuku's most beloved best friend, due to Kaori being the first girl to showed her kindness and compassion during her childhood time. Instead of persecution like most other girls her age for her friendship with Kouki as well as her brave efforts, Kaori was able to encourage Shizuku to get her own desires as she wants to be more girlish. This is seen when Kaori was scolding Shizuku's grandfather Shuuzou for not letting Shizuku grow out her hair as a girl. Because of this Shizuku is extremely devoted towards Kaori, often supporting her attempts to get along with Hajime to win his affection. After Hajime fell into the Abyss, Shizuku promised Kaori that she would help her discover the truth what happened to Hajime and to give Kaori peace.

In Volume 4, during Cattleya's ambush of the "Hero Party", when it seemed that Shizuku was about to be killed by the monsters that Cattleya brought, Kaori rushed to Shizuku's side, determined to stay at her best friend's side at the end of their lives. After Hajime saved the "Hero Party" and Kaori decided to go with him, Shizuku was the main person supporting her decision as Kaori was thankful for her support but was regretful about having to part from her best friend.

In Volume 6, when Kaori is killed by Daisuke Hiyama during the Demon Invasion, she is really devastated and almost breaks down if Hajime did not console her. After Kaori is revived, Shizuku is extremely happy and hugged her while crying loudly. Shizuku is very loyal to her as seen on her attitude that she refused to accept that she loves Hajime because that would mean that she betrayed Kaori and will make her hate Shizuku. After Shizuku tells Kaori her feelings for Hajime, Kaori does not condemn her and instead asks her to rival against Yue and Shea along with her as comrades, stating that she is happy that Shizuku has started to put her desires above always helping others.

However, Shizuku became disturbed when Kaori started displaying the qualities of a yandere and a stalker. She even felt sorry for Hajime when Kaori starts making plans to get closer to him after she falls for him. Shizuku became also bothered when Kaori started suggesting they team up and assault Hajime at night together.

In the After Story, Shizuku and Kaori live together with Hajime as his wives.

Yue
Shizuku gained the attention of Yue after she brought Hajime to his knees with words alone. Hearing more about Shizuku from Kaori and seeing Hajime give her a new sword caused Yue to see Shizuku as the last boss for Hajime's affection.

Shea Haulia
She has a close friendship with her. Initially though, Shizuku is subconsciously jealous of Shea due to Hajime also choosing Shea as a lover.

Tio Klarus
She shares the opinion of everyone with regards that Tio is a pervert.

Aiko Hatayama
Shizuku has a close friendship with Aiko, as she is the only one Aiko would discuss her thoughts and worries with. Aiko also trusted Shizuku enough to asked her to gather her classmates in to order to reveal what Hajime learned about Ehit. While Shizuku also care dearly about Aiko but was dismayed when she learned that Aiko has fallen for Hajime as well.

Myu
Shizuku is won over by Myu's cuteness during their brief encounter in Horaud.

Liliana S. B. Heiligh
Shizuku finds Liliana to be one of her best friends after she is summoned to Tortus.

Kouki Amanogawa
Kouki is one of Shizuku's oldest friends who is usually the one who is forced to deal with the consequences of his constant dense outbursts and his constant habit of interpreting any situation to his own convenience. The two met each other when they were little when Kouki started to train in her family's dojo. At first, Shizuku thought that she would fall in love with Kouki, thinking that he could be the special one that would understand her and accept her even if she wasn't strong. Nevertheless, shortly after she understood Kouki's nature, she realized that her hopes were wrong. However, she continues being his friend as she saved him from Eri's Soul Bind mind control and stated that she views Kouki as family while she is in love with Hajime. Eventually their relationship becomes something more similar to an elder sister and younger brother with Shizuku taking care of Kouki and giving him advice when he needs it.

Ryutarou Sakagami
Ryutarou is one of her childhood friends and fellow Returnees group. Unlike Kouki, Ryutarou only considered Shizuku as a friend, as he allowed Shizuku to be in love with Hajime to ensure his safety from Hajime's bad side after murdering Hiyama.

Suzu Taniguchi
One of her fellow classmates that were transported to Tortus. She is usually the one to stop Suzu and her perverted attacks on the other girls in their party.

Eri Nakamura (Deceased)
Shizuku was a close friend of Eri Nakamura. However, their friendship was only one sided on Shizuku's part as Eri has always been murderously jealous of her and Kaori's close friendship with Kouki to the point Eri holds absolute hatred towards Shizuku and Kaori that she wished to kill Shizuku and Kaori with her own hands, considering her to be worthless trash alongside the rest of her classmates, and even outright stated that pretending to be her friend was really sickening. Along with Daisuke Hiyama, Eri chose to give her allegiances to Ehit and backstabbed Shizuku and her fellow classmates in order to massacred and zombify them into her personal undead army. Eri even planned to zombify Shizuku and then to kill her best friend Kaori but failed due to Hajime's arrival.

Daisuke Hiyama (Deceased)
Despite being her classmate, Shizuku holds great hatred and disdain towards Daisuke for his cruelty towards Hajime for his bullying and his flirting with Kaori which was scaring her. After Daisuke killed Kaori in order to make her his undead slave, Shizuku's hatred towards Daisuke increased even more. After witnessing Hajime killed Daisuke by throwing him to be eaten alive by monsters, she has no qualms or sympathies about it as she could never forgive him or anyone else who hurts her best friend. Unlike Kouki, Shizuku doesn't condemned Hajime for his murder.

Ehit (Deceased)
Shizuku once respected Ehit under the "Hero Party". After learning from Aiko and Princess Liliana what Hajime had told them of Ehit's true nature as an Evil God and how she was used as a pawn in his game of death like the rest of her classmates, Shizuku lost all of her respects for Ehit and sided with Hajime.

Soul Sisters
Shizuku's so called fan club and later her enemies after she married Hajime.

A (semi) secret organization formed from young females on both Japan and Tortus who once idolized Shizuku, calling her Oneesama (including the ones who are older than her). While Shizuku tries to be nice to them, she's usually annoyed by their affection for her. She's further annoyed by how they keep trying to break her relationship with Hajime, seeing him as no good for her. When they were bullied by Hajime, Shizuku refused to help them when Hajime humiliating the Soul Sisters in public for their interruption at their wedding ceremony. Because of this, her so-called "fans" lose all their respects for her and became her enemies instead.

Gahard D. Hoelscher
Gahard is infatuated with Shizuku and has made repeated attempts to make her his mistress, but Shizuku always refuses his offer and has made it clear to him that she is not interested in him.

Nia (Deceased)
Nia acted as Shizuku's personal maid. She feeled a kinship with Shizuku since they were both trained in swordsmanship at an early age. At first, Nia was nervous serving someone that is considered to be one of Ehit’s chosen Heroes, but she eventually came to see Shizuku as a friend. She was worried about Shizuku when she and the other heroes explore the uncharted floors of the Great Orcus Labyrinth and was bothered when everyone treats Shizuku like she is a special being since all of those expectations would wear her down. Unfortunately, Eri used Shizuku's friendship with Nia against her during the Demon Invasion to make Shizuku lower her guard so the reanimated Nia could stab her in the back. When Nia attempted to kill Shizuku, Hajime arrived and went berserk destroying Nia's body and the rest of the undead when he witnessed Kaori's (temporarily) death.

Akari Fudo
Shizuku and Akari have competed against each other at kendo tournaments for years. Akira has an inferiority complex with Shizuku due to always losing to her. Shizuku does not hold any animosity towards Akari and tries everything to help her overcome her negative emotions.

Yaegashi Dojo Students
The students of her family's Dojo who are treated like family. All of the students immensely admire Shizuku, referring to her as Ojou. Despite some of them having government jobs, they prioritize the Yaegashi family over their positions, which is why they are also told about Tortus and Shizuku's abilities. However, Shizuku has grown increasingly annoyed by how they repeatedly attack her lover/husband, Hajime, every time he comes to her house only for them to be easily defeated by him.
