Ozen/Relationships

Jiruo
Ever since Jiruo declined Ozen's offer to become her apprentice she only refers to him as "brat". However, when Jiruo visited her in the Seeker Camp, it was shown that she doesn't actually hold a grudge against him.

Lyza
Before becoming a White Whistle Delver herself, Lyza studied under Ozen as an apprentice. They became very close friends, and Ozen is very fond of Lyza. When Lyza introduced her husband, it greatly stunned Ozen at first and she appeared dismayed and unaccepting of the decision.

Marulk
As her student, Ozen is very fond of Marulk and strict with him at times. She takes teaching him seriously.

Nishagora
Nishagora seems to have crossed paths with the Unmoveable Sovereign at some point, as she has some knowledge of the White Whistle's physical limits.

Reg
Despite Reg being a valuable "Treasure of the Abyss", Ozen instructs him normally, like any other Delver, and only showed interest in helping to develop his abilities.

Riko
When Riko was stillborn, Ozen thought of the child as a nuisance due to causing Lyza grief. However, she promised Lyza to tell Riko the truth about her birth when the right time came. During Riko's and Reg's training she seems to have grown more fond and accepting of Riko.

Subterranean Bandits
They respect Ozen and follow her instructions. Despite her calling them "good for nothings", it is seen that she cares for them too.

Torka
Ozen was dismayed and disdainful of Lyza's marriage to Torka and thus not very fond of him. After his death, she cursed Torka for impregnating Lyza before dying and leaving Lyza alone.
