Shizuku's father and 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 childhood friends (especially Kaori) that often puts him in trouble. She is devastated when he falls into the abyss after protecting her and the rest of their class while also becoming angry towards those who were badmouthing him in the kingdom. At first she does not think much of Hajime besides being the love interest of her best friend, but after Hajime saves her and Kaori in Great Orcus Labyrinth, she feels great gratitude and drastically changes her impression of him. Unlike the rest of their classmates, Shizuku could still get along with Hajime with him even giving her a new enchanted sword that better suited her fighting style. She found herself very attracted to Hajime's crimson magic color and overwhelming strength, considering it beautiful. She starts to develop feelings for Hajime after the demon invasion to Heiligh's capital and becomes conscious of them during the Haltina Woods Labyrinth trial. Despite that, she refuses to acknowledge her feelings because she believes that as proof of betrayal towards Kaori. During her time in the Frost Caverns, she comes to terms with her feelings and confesses to Hajime. She falls in love with him because he is the only person that protects her and see through her strong cover, not expecting her to always be strong and expecting her to take care of the others all the time.

After returning to Earth, Shizuku has become one of Hajime's wives and is always happy whenever she's around him. 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. She's really caring towards Kaori and often supporting and helped her to get along with Hajime on how to win his affection. After Hajime fell into the abyss, Shizuku promised Kaori that she would help her discover Hajime's fate to give Kaori peace of knowing the truth about what happened to him. During the demon ambush of the Hero Party, Kaori managed to save Shizuku's life with her spells. When it seemed that Shizuku was about to be killed by the monsters that the demon 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 regretful about having to part from her best friend. When Kaori is killed by Daisuke Hiyama during the invasion of the demon race, 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 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 (Kaori) falls for him. Shizuku became also bothered when Kaori started suggesting they team up and assault Hajime at night together.

Yue
Shizuku gained the attention of Yue after she (Shizuku) 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 choosing Shea as a lover.

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

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

Kouki Amanogawa
Kouki is one of Shizuku's her 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 the start, Shizuku thought that she could 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 and the fact that her hopes were wrong. However, she continues being his friend, and 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.

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.

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.

Nia
Nia acts as Shizuku's personal maid. She feels a kinship with her since they were both trained in swordsmanship at an early age. At first, she is nervous serving someone that is considered to be one of Ehit’s chosen heroes, but she eventually comes to see Shizuku as a friend. She is worried about Shizuku when she and the other heroes explore the uncharted floors of the Great Orcus Labyrinth and 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.

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.

Soul Sisters
A (semi) secret organization formed from young females on both Earth and Tortus who worship Shizuku, calling her Oneesama (including the ones who are older than her). While Shizuku tries to be nice to them, she's usually disturbed by their affection for her. She's further annoyed by how they keep trying to break up her and Hajime, seeing him as no good for her. Whenever they try to do something to Hajime, Shizuku doesn't try to help them when Hajime harasses or punishes them in return.

Yaegashi Dojo Students
The students of her family's Dojo who are treated like family. All of the students greatly 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 attacks her lover, Hajime, every time he comes to her house.
