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 primarily her target because of his necessary alliance with Brahman that would help the gang in defeating Manjiro Sano and the Kanto Manji Gang, but she soon comes to trust him as they hang out and become friends. Senju is devout to their friendship despite only knowing each other for a short amount of time; she promised to protect him as she had written and wished on a Tanzaku, and eventually fulfilled this wish as she rescued him from danger moments later. Senju was not reluctant to save him from Rokuhara Tandai's cronies who planned to kill him in exchange for high merit in the gang, proving her trueheartedness at being his friend.

When Senju revealed the truth of Mikey's Dark Impulses, claims it to be her fault and calls herself a loser, Takemichi says that he is also a loser and their pasts can be changed. She is deeply motivated and impressed by him, thus, joining the 2nd Generation of Tokyo Manji Gang as the Head of 5th division.

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 support her dream of establishing a mighty gang that would defeat the Kanto Manji Gang of Shibuya. Senju has been shown to care for him and her other colleagues, as she had stood up for Wakasa when he and Benkei got taken down by South Terano. Generally, Senju obeys his orders as the younger person, 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.
