Hajime Nagumo/Relationships

Yue
Yue became Hajime's most important person after he fell into the Abyss. The two quickly grew close due to their similar backgrounds and similar circumstances. Even in public, they tend to go into their own "pink world" and ignore everything in their surroundings. Whenever there is danger Hajime and Yue always prioritize the other's safety. Even though Hajime is surrounded by women who want to be his lovers and Yue herself wants him to be intimate with Shia, he has never wavered. His reasoning being that he is a man who would never cheat on the woman he loves and wants to be monopolized by Yue since, if the situation was reversed, he would never want Yue to be with anyone but him. It is Hajime's wish to bring Yue and the other girls back to his world.

Kaori Shirasaki
Hajime has always seen Kaori as a friend even though her attention brought him nothing but trouble. When Hajime began his travels he had decided to discard his former classmates after his transformation but the moment he heard Kaori was in trouble he went into a dungeon to save her to repay her kindness. In the end, Kaori decided to travel with him determined to win his affection despite his drastically different personality.

Shea Haulia
During their first meeting Hajime's impression of Shia was bad due to her excessive clingy attitude. Hajime wouldn't allow Shia to travel with him until she became strong so she trained with Yue so that one day she could stand next to them in battle. As time passed Hajime and Yue began to see Shia as part of their family but to Shia's and shockingly Yue's great disappointment Hajime could not see Shia in a romantic light. However. that began to change when Hajime realized that Shia is just as important and irreplaceable to him as Yue and has begun to show his previously hidden feelings for her. Without realizing it the two have created their own "pink world" while they are alone.

Tio Klarus
After defeating and arguably "tainting" her, Hajime has been followed by the masochistic and incredibly perverted Tio who refers to him as her "master". Hajime constantly finds himself punishing her for her various misdeeds during their travels which makes Tio incredibly happy and disgusts everyone else. During their fight against Freid Bagwa, Tio admitted 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 Myuu's safety while he and the others went into a dungeon. Hajime later confesses that he loves her when her father and the rest of the dragon race decide to help him wage war on Ehito.

Shizuku Yaegashi
Hajime cannot handle Shizuku for she knows his secrets such as chuunibyuu stuff. Shizuku later admits to him that she has feelings for him.

Myu
Hajime and Shia saved her from a sewage system after she escaped from slavers. Myuu immediately bonded with them and began called them "Onii-chan" and "Onee-chan". Later on, after Hajime and co. once again saved her from slavery she began calling him "Papa" much to Hajime's chagrin. As they travelled together Hajime began acting more and more like her father, from being incredibly overprotective to scolding and subsequently comforting her when she put herself in danger. After returning Myuu to her mother, Lemia, who started referring to Hajime as her husband, Hajime decided to take them with him once he returns to his world which both mother and daughter happily agreed to.

Kouki Amanogawa
Hajime has a neutral standing about Kouki and ignores the fact that Kouki envies him. He only has a bit of good intent to Kouki because he is a close friend of Kaori.
