They are Yuka's closest friends.

Aiko Hatayama
Yuka is overprotective of Aiko.

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 for his survival but was sadden 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 in coldblooded. She is shown to have a crush on him as time passes. Eventually, the two of them get along to the point where all of their classmates call her his 'Mistress' (though both deny any romantic involvement between each other).

Simon Levellair
Yuka first saves Simon from being mobbed by the citizens of the Heiligh Kingdom. She was grateful to him that he will listen to her dilemma with regards on how she is moving forward with her life and offered her words of encouragement.
