Yuka Sonobe/Relationships

Yuri & Hiroyuki Sonobe
They are Yuka's parents. Both love their daughter very much, Yuka also loves her parents very much. After the summoning, Yuri and Hiroyuki did everything they could to find Yuka, being relieved and happy after she returned. The two are well aware of their daughter's feelings for Hajime and appear to have nothing against her entering the boy's harem. Although it seems that her mother is more open about it than her father.

Nana Miyazaki
One Yuka's closest friends.

Taeko Sugawara
One Yuka's closest friends.

Aiko Hatayama
Yuka is overprotective of Aiko. Aiko sees Yuka as one of her students and worries a lot about her, after Hajime kills Shimizu, Yuka comforts her. After returning to Japan, Aiko is one of Hajime's wives while Yuka is a lover.

Hajime Nagumo
Yuka was grateful to Hajime for saving her in the Great Orcus Labyrinth and wishes to pay him back. When she meets him again in Ur, she was surprised that he survived but was saddened by how much he has changed. She further became shocked by how powerful he had become and how he had two beautiful girls with him who are in love with him. Despite this, she still took the time to thank him for saving her and vowed to him she wouldn't waste it. Hajime also gave her words of comfort that helped her with her trauma. She is terrified a little bit of Hajime when he murdered Hiyama. She is shown to have a crush on him as time passes. Yuka has shown to be afraid of Hajime due to his murdering intents and monstrous strength when he murdered both Yukitoshi Shimizu and later Daisuke Hiyama in coldblooded.

After returning to Japan, the two of them get along with each other to the point where all of their classmates call her his 'Mistress' (though both deny any romantic involvement between each other). Yuka also developed certain habits when returning to Japan such as fiddling with her scarf and tapping her foot on the ground and would only do it whenever Hajime was around. Though she probably still holds romantic interest in Hajime, she has also stated that she has no plan to enter his harem. Despite this statement,it is implied that she is likely to become his actual mistress someday.
