Senju Kawaragi/Relationships

Haruchiyo Sanzu
Sanzu is Senju's second older brother. Not much is known about their relationship except for Sanzu's withdrawal from the Akashi family and his indifference toward Senju and Brahman as a whole. While out on a date with Takemichi, Senju tells him that Sanzu could not care less about her status as Brahman's strongest and current boss.

Takeomi Akashi
It is clear that Senju holds a deep bond with Takeomi as seen in their interactions. Takeomi is Senju's right-hand man and her oldest brother. Their relationship seems to be good and he seems to be in disbelief when Senju lets out her emotions when they're doing business.

Takemichi Hanagaki
Senju and Takemichi never met in the previous timeline or future. Takemichi was only Senju's target to recruit due being the former 1st Division Captain of Toman and the last successor of the Black Dragon to defeated Mikey and Kanto Manji Gang. After Takemichi joined Brahman and being Senju's gopher, he was shocked that she was girl and having a different personality from being Brahman's boss.

They end up quickly becoming friends as she vowed to protect him.
