Kai Chisaki/Relationships

Shie Hassaikai
Overhaul is the leader of his organization. He does not appear to have a level of respect or care for his subordinates beyond their use. This was evident when he used one of his subordinates as a human shield and chastises another subordinate for being slow.

Despite how he treats them, the members appear to value Overhaul as their leader and willing to protect him.

Former Head of Shie Hassaikai
Chisaki appears to greatly respect the former boss, and even thinks of him as a father figure. The former head in return respects Chisaki, yet does not agree with the latters extreme methods. Chisaki is aware that most of those in Shie Hassaikai only stay because of the former boss and not out of love for him, but Chisaki believes that he alone cares about their bedridden boss more than anyone.

Chronostasis
Chrono is a member of the Eight Precepts of Death and one of the few members Overhaul does not treat like a disposable object. This is most likely because Chronostasis's abilities are of higher use than most of the members which places him as a valuable asset to the organization. Also it’s been revealed that Chrono and Chisaki knew each other since childhood.

Mimic
Mimic is a member of the Eight Precepts of Death. Similar to Chronostasis, Mimic is treated as a valued member of Overhaul's organization and not considered expendable. Mimic is incredibly loyal to Overhaul. Despite his stature and being the General Manager of the organization, Mimic accompanies Overhaul during his exploits and protects him from potential threats.

Eri
Eri is an important person to Overhaul. Similar to Chronostasis, Overhaul treats her better than most of his other subordinates because of her use.

From the information gathered by Nighteye's office, it is assumed Overhaul is using Eri's blood to create and sell his Quirk attacking darts. However, the most disturbing aspect is the theorized process; based on Nighteye's investigation, Overhaul supposedly uses his Quirk to destroy and reassemble Eri in order to mass produce his product. From this supposed treatment, Overhaul truly does not care about Eri as a person (or the fact she is his former leader's granddaughter) and only sees the value of her because she is the key to his plans.

Eri fears Overhaul, both from his treatment of her to produce his Quirk attacking darts and his killer intent. This fear runs very deep as his killer intent was enough to make her return to his side, despite how much she wanted to get away from him.

League of Villains
Overhaul does not show interest in joining the League of Villains due to their apparent lack of planning. He only sees their influence as a means for his motives. The League initially had interest in Overhaul and his organization before coming into a disagreement when Overhaul brought up his motives.

The meeting caused a conflict between the two, resulting in casualties on both sides, further angering the league. Despite this unstable relationship on both sides, Overhaul still saw value in the league and encourages them to figure things out before contacting him again.

Overhaul also treats the league with some level of level-headedness and sentiment, as he wanted to bring out the full potential of the league by having them work under him. He only acted violently when the league threw the first punch and apologized to Mr. Compress for destroying his arm.

However, when he was defeated by Izuku Midoriya and being transported to a hospital Tomura attacked the police escorting him. Overhaul was not fazed by their appearance but he got angry when they stole his quirk drug, however, his rage turned to fear as Mr. Compress and Tomura decayed and took his arms. Tomura then taunted the now helpless and powerless Overhaul who was reduced to screaming as Tomura made off with his creation which he claimed for himself.
