Tio Klarus/Relationships

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

Kharge & Orna Klarus
Tio loved her late parents deeply. However, when her parents died along with her people by the manipulation of Ehit, their death has made Tio vengeful and she desires to find a very powerful group to ensure that her vengeance will be absolute as it was the reason why she joined Hajime's group. Both of her parents and people were later avenged when Hajime killed Ehit.

Hajime Nagumo
Her master and the one who awakens her perverted nature after he defeats her in battle. After defeating and arguably "tainting" her (which Tio even implies is what awakened his masochism), Tio decides to accompany Hajime 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, much to his dismay and the others. In his unofficial date with Shea in Fuhren, Hajime reveals that he thinks Tio is not a bad person, just a pervert. Later in Volume 4, Hajime entrusts her with Myu's safety when he and the others went into the Great Orcus Labyrinth to rescue Kaori and the rest of his classmates. In Volume 5, 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. Hajime later confesses that he loves her when her grandfather and the rest of the Dragonmen Tribe decided 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, but he still gets annoyed by her.

Yue
Yue greatly respects Tio as a member of the Dragonmen race, but is put off by her perverted antics. Despite Shea calling Tio crazy, Yue acknowledges Tio and sees her as a powerful asset in battle.

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. When Shea was on a unofficial date with Hajime, she says that 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 also have some perverted qualities as well, she tries to hide it behind Tio's antics hoping 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 over-responsible personality and encourages her to loosen up a bit, 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 first met Aiko in the mountains. And she later destroyed the Holy Church with a little help from Aiko.

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. Myu also sees Tio as a pervert and masochist, to the point where she recommended using her as a meatshield in a snowball fight.

Shuu Nagumo & Sumire Nagumo
The in-laws of Tio.

Ehit
As the mastermind who killed her parents and subjects, Tio holds a great hatred towards Ehit and sworn to avenge her parents and the people's deaths which ended to a success after Hajime killed Ehit.

Yukitoshi Shimizu
When he first encountered her, Tio was in a deep sleep. Using this chance, he brainwashed Tio into killing Will and all other witnesses. However, it later backfired after Tio, who was released from the brainwashing, helped Hajime and his comrades in defeating his Monster army. Tio later witnessed Hajime murdering him afterwards.

Venri Colt
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
Kuwaibel idolizes Tio and views her like a mother.

Suzu Taniguchi
Tio feels a sense of comradely 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.
