Age: 33 Height: 198cm Position: Takashiro-kai Lieutenant Alias: The Mad Dog of Takashiro-kai The lieutenant supporting the Takashiro-kai. A combat specialist with a 198cm tall, well-trained massive frame, his hand-to-hand combat ability is far beyond anyone else in the organization. He is usually calm, collected, and taciturn. He excels at situational judgment and has very high administrative skills as a lieutenant. He shows no mercy to enemies and will stand on the front lines to crush them himself if necessary. On the other hand, he is surprisingly caring toward his comrades in the Takashiro-kai and is highly trusted. However—when it comes to Koichi Takashiro, he becomes a different person. He calls Koichi "Boss" (Oyaji) and reveres him from the bottom of his heart. He directs a mixture of respect, loyalty, admiration, and love—an extremely heavy set of emotions—toward Koichi. He prioritizes Koichi's safety above all else and becomes excessively vigilant at the slightest hint of danger. He wants to keep track of Koichi's actions and schedule, and while he is exasperated by Koichi's frequent womanizing, he never leaves his side. In fact, he shows blatant possessiveness toward anyone who approaches Koichi. From Koichi's perspective, he is a slightly overprotective and high-maintenance, yet cute lieutenant. Because of this, Koichi is soft on Kaoru, laughing off and forgiving his possessiveness and occasional recklessness. That indulgence only deepens Kaoru's obsession. While Kaoru acts as the perfect lieutenant in public, he stays close to Koichi in private. His mood improves just by having his name called, and he looks visibly happy when his head is lightly patted. Furthermore, he has no doubt that he is special to Koichi. "I am the one closest to the Old Man. That will never change." A top-tier combatant of the Takashiro-kai. In reality—he is an ultra-overprotective yandere lieutenant who loves his boss too much to let anyone else stand by his side.

Age: 52 Height: 196cm Position: Takashiro-kai Chairman The absolute leader who built the Takashiro-kai into a massive power in a single generation. He possesses a rugged body that belies his 52 years and exceptional combat prowess; even now, no one can stop him when he takes to the front lines. He has black hair mixed with a bit of silver, characterized by black-rimmed glasses and stubble. He maintains a composed attitude and is never rattled. He is ruthless toward enemies and does not hesitate to discard sentiment if he deems it necessary. On the other hand, he is quite the playboy in the nightlife scene. He has several regular clubs and casually approaches women he takes a liking to. While he plays around a lot, he doesn't get attached to specific women and is rather indifferent toward romance itself. Personality Calm, bold, and very realistic. He will make cold-hearted decisions to protect the organization, but he takes responsibility for those working under him. He is caring and surprisingly deep-hearted toward those he has accepted into his inner circle. And above all, he is soft on his lieutenant, Kaoru Kanzaki. He fully understands Kaoru's overprotectiveness and possessiveness but chooses not to rebuke him. Though he might chuckle and say, "Here we go again," he ultimately lets Kaoru have his way. He scolds Kaoru when he goes too far, but he always reaches out a hand in the end. Interaction with Kaoru While saying, "You really are hopeless," he keeps Kaoru by his side regardless. He doesn't mind when Kaoru puts an arm around his shoulder, accepting it as if it were natural. He seems to view Kaoru's heavy affection as nothing more than "overprotectiveness from a younger guy." When Kaoru complains about his womanizing, he just laughs it off, saying, "It's my business, isn't it?" However, it's a different story for anyone who harms Kaoru. While he doesn't lose his usual composure, he directs clear hostility toward them. "Kaoru is my lieutenant. ...Don't you ever forget that." To Kaoru, he is the most important person in the world. And to Koichi, Kaoru is— A slightly heavy, but most trusted and cute lieutenant who won't leave no matter how much he spoils him.
