Tio Klarus/Relationships

Adul Klarus
Her grandfather. Adul vows to protect his granddaughter after the death of her parents and will do anything for her happiness.

Hajime Nagumo
Her master and the one who awakens her perverted nature after he defeats her in battle. After defeating and arguably "tainting" her, Tio decides to accompany on his journey while constantly expressing her perverted nature. Hajime constantly finds himself punishing her for her various misdeeds during their travels, which makes Tio incredibly happy. In his unofficial date with Shea, Hajime thinks Tio was not a bad person, but still a pervert. During their fight against Freid Bagwa, Tio admits her true love for Hajime before escaping per his orders. Since then, Hajime has become "slightly" more tolerant of her and sees Tio as a member of their group, even going so far as to trust her with Myu's safety while he and the others went into the Great Orcus Labyrinth to rescue Kaori and the rest of his classmates. Hajime later confesses that he loves her when her grandfather and the rest of the dragon race decide to help him wage war on Ehit. While Hajime still punishes Tio like he did before, he does it with more affection compared to how he mainly did out of annoyance before (not that he still doesn't get annoyed with her).

Yue
Yue greatly respects Tio as a member of the dragonman race, but is put off by her perverted antics. Despite of Shea called Tio crazy, Yue acknowledged of Tio will be a powerful asset.

Shea Haulia
Like everyone else, Shea considers Tio to be a huge pervert, but she also views her to be the wisest and most composed of her companions. While Shea dating Hajime, she likes Tio in spite of being a pervert. Shea sees a lot of her mother in Tio and feels safe whenever she is around.

Kaori Shirasaki
One of Tio's companions. She shares the same opinion with everyone with regards of Tio being a pervert. Though Kaori is shown to have some perverted qualities as well, she tries to hide behind Tio's antics in the hopes that it would overshadow hers. After Hajime accepts Shea as a lover, Kaori and Tio constantly support each other in order for him to accept them as well.

Shizuku Yaegashi
One of Tio's companions. She shares the same opinion with everyone with regards of Tio being a pervert. They are also similar due to the fact that each of them acts like a older sister towards their individual group. Tio sees that Shizuku tends to worry a lot due to her overresponsible personality and encourages her to loosen up so that she doesn't worry those close to her. Tio was able to notice Shizuku's hidden feelings of love for Hajime and subtly encourages her to pursue them so she can find her own happiness.

Aiko Hatayama
Tio

Remia
Tio and Remia work alongside Hajime on his business ventures after they go to Earth with him. The two of them have also created their own line of clothing. While they are close, Remia tends to get sucked into various mischief that Tio causes due to her perverted personality such as dressing like a sailor girl when Tio did, a event which caused deep trauma and a scar on her heart. While she is normally tolerant of Tio's perverted personality, Remia is very strict with her if it seems like she is going to influence Myu with it due to Remia wanting to maintain Myu's innocence.

Myu
Like Hajime and the wives, Tio is protective of her.

Ehit T
As the mastermind who killed her parents and subjects, Tio holds a great hatred toward the so-called "god" and sworn to avenged her parents and peoples' deaths which ended to a success after Hajime killed Ehit.

She also eventually hates the Holy Church killing her parents and people. For the Church's interference in Hajime's fight with Noint, Tio was ordered by the latter to destroy the Church's temple which purposely kills both the pope and his bishops to exacted her revenge for killing her parents and people.

Freid Bagwa
After he ambushed and injured Hajime, Tio, in her dragon form, attacked and severely injured Freid but unable to kill him after he got away but leaving scars on him from Tio's wrath.

Venri
Tio's caretaker since childhood. Venri is like a second mother to her.

Ristan
Ristan loves Tio, but Tio considers him to be like a younger brother.

Kuwaibel

Suzu Taniguchi
Tio feels a sense of comradery with Suzu since they both have perverted qualities. Tio has also taken a liking to her as Tio helps to make Suzu grow stronger by offering advice and teaching her how to use metamorphosis magic. Later, they become close friends.

Will Cudeta
Will resents Tio at first since she is the one who killed his comrades (albeit while mind-controlled), but he forgives her after she help saves the town of Ur from Yukitoshi Shimizu's monster army.

Kouki Amanogawa
Like her lover/master/husband, Hajime, Tio is annoyed of Kouki's annoying sense of "justice". When Kouki tries to "convince" her of leaving Hajime and join him to treat her better, Tio is furthermore annoyed by his ignorance and refused his offer due to her absolute loyalty to her master.
