Kaoruko Awata/Relationships

Sir Nighteye
Bubble Girl was one of Sir Nighteye's Sidekicks, and she was usually the one who would report any new information to him. Bubble Girl respected Sir Nighteye, but also held fear toward him because he usually punished her when she didn't show enough enthusiasm in her reports or failed to perform her tasks by his humorous standards.

In spite of everything, she appreciated her boss, leaving her heartbroken when he died from his injuries suffered during his confrontation against Overhaul.

Centipeder
Bubble Girl has a good relationship with her coworker Centipeder. The two usually collaborate together to perform tasks and support each other. Centipeder was comforting Bubble Girl the whole time when Sir Nighteye was on his deathbed.

When he takes over Nighteye Agency, she continues to work there, helping him with the pile of paperwork.

Mirio Togata
As a trainee of Sir Nighteye, Bubble Girl is very friendly towards Mirio due to his good mood, positive attitude, and because he usually pulled her out of Sir's punishment machines, although Bubble Girl admits that she is quite jealous towards the good treatment and preference that Nighteye professes for him. After Nighteye's death and despite Mirio losing his Quirk, Bubble Girl tells Mirio that she and Centipeder will welcome him back anytime to Nighteye's Office.

Izuku Midoriya
There weren't many interactions between her and Izuku during the Work-Studies program, but of the few there were between the two, Bubble Girl seemed to appreciate Deku.
