Senju Kawaragi/Relationships

Haruchiyo Sanzu
Not much is known about Senju's relationship with Sanzu except for Sanzu's withdrawal from the Akashi family and his indifference toward his younger sister and Brahman as a whole. While hanging out with Takemichi Hanagaki one day, Senju tells him that Sanzu could not care less about her status as Brahman's strongest and current boss. For this reason, he is currently a member of the Kanto Manji Gang.

Takeomi Akashi
Senju deeply trusts Takeomi, at least before he was once again blinded by the absolute power and authority he was granted with in Brahman. Apart from being her older brother, Senju appointed him as her right-hand man and advisor because she believed in his ability to share his wisdom in guiding her through her gang duties. However, she gradually becomes dubious toward his actions as their perceptions would frequently clash; Senju's emotional and "heart-over-mind" attitude heavily differs with Takeomi's rationality, and as the younger sibling between the two, she is frequently compelled to heed his orders and decisions. Senju fears that Takeomi would eventually cave into sin the more she exhibits her strength and power, hence her decision to lock away her true potential from her brother. Soon enough, however, she wields her strength in battle to command Brahman to victory, all the while reassuring Takeomi that he was not at fault for any of his past actions.

Takemichi Hanagaki
Despite not having met each other in the previous timelines, Senju bonds with Takemichi very well. He was only her target to recruit due being the former First Division Captain of the Tokyo Manji Gang and the last successor of Black Dragon that would help Brahman in defeating Mikey and the Kanto Manji Gang. After Takemichi joined Brahman and being Senju's gofer, he was shocked that she was a girl and having a different personality from being Brahman's boss.

Wakasa Imaushi
Wakasa is one of Senju's close friends, possibly even one of her brother-like figures. She frequented his gym with Keizo Arashi where she flawlessly stood as the strongest member, which caused Wakasa to wholeheartedly support her dream of establishing a mighty gang that would defeat the Kanto Manji Gang of Shibuya. Senju was shown to care for him and her other colleagues, as she had stood up for them when he and Benkei got taken down by South Terano. Generally, Senju obeys his orders as the younger person between them, but she does not hesitate to flout them if his actions lead him to danger.

Keizo Arashi
Like Wakasa, Benkei supported Senju's dream of creating a team of her own, encouraging her on by complimenting her unordinary strength against her opponents in Wakasa's gym. Senju's trust in him and their close relationship with one another is evidenced by his top executive position in Brahman, as he had been serving the gang since its establishment. Senju also cares for him and would take anybody on when he is in the face of uncertainty.
