Kashira, also referred to as Baba Kashira, is a supporting character within the yakuza organization that serves as the setting for much of the series. He holds the position directly under the leader of the Ashikawa-gumi, making him one of the ranking men in charge of operations and personnel. His appearance and demeanor are those of a traditional, stern yakuza captain, deeply rooted in the organization's hierarchy and code of conduct.

In terms of personality, Kashira is defined by his powerful convictions and a strict, no-nonsense approach to leadership. He carries his beliefs vehemently and is known for handling his underlings roughly, demanding discipline and respect. Despite this tough exterior, his judgment is shown to be nuanced. He holds a genuine approval for Nitta, one of his men, recognizing his value and character. However, this approval is conditional and situational; he is prepared to treat Nitta like a bullet depending on the circumstances, meaning he values Nitta as a tool to be used when needed but would not hesitate to discard him for the good of the organization.

Kashira's primary role in the story is to represent the yakuza world that Nitta is a part of. He acts as a balancing force, swinging between providing support for Nitta and reminding him of the dangerous reality of his profession. His presence injects moments of tension and dark comedy, as his fierce demeanor clashes with the increasingly absurd domestic life Nitta is forced to lead in order to care for Hina. The character’s trajectory shows a leader who is constantly adapting to the bizarre situations brought on by the psychic girls, often with a gruff resignation that underscores his loyalty to his men and his organization.

His most significant relationship is with Yoshifumi Nitta, whom he supervises directly. While he approves of and trusts Nitta more than other subordinates, he is also willing to make difficult decisions involving him for the sake of the family. Kashira also interacts with the upper echelons of the organization and is involved in critical events such as the election of a successor, highlighting his importance within the group's internal politics. Notably, some storylines also involve Kashira interacting more directly with Hina, the protagonist, showcasing his ability to tolerate her unusual presence. Regarding notable abilities, Kashira does not possess any supernatural powers like the main characters, but his influence and authority as a high-ranking yakuza officer are his primary strengths.
