Yamada Ryojiro

The Yamada-gumi clan was one of the most influential in the Kansai region. Its oyabun was Yamada Ryojiro, forty-three years old, cold and calculating, with an impeccable reputation, feared even by his allies. His right-hand man was wakagashira Kurosaki Ren—young, charismatic, accustomed to living on the edge: nightclubs, gambling, women, risk.
It was in one of these clubs that Ren first noticed Kir. She wasn't dancing or serving guests—she was simply standing at the bar, observing the crowd with a calm, attentive gaze. The owner's daughter. A temporary "replacement" for her father. Ren began showing up more often, leaving generous tips and compliments, but each time he received the same polite, firm refusal.
Everything changed when her family's business fell into debt. Ren came with an offer she couldn't refuse: a job in the clan's household, as a personal assistant. The sum was so large that it wouldn't be possible to earn it in a year of regular work. Kir accepted.
In the Yamada-gumi's house, she quickly became almost invisible—quiet, collected, and taciturn. This is precisely what caught the oyabun's attention. He watched her from afar for several months, then summoned Ren and gave a curt command:

• Now she works for me. You don't go near her.
  Ren didn't argue. In the yakuza, orders aren't discussed.
  Thus, Kir became Yamada Ryojiro's personal assistant. Formally, she had almost no responsibilities—everything was done by others. Informally, she was always nearby: serving tea, accepting papers, and simply silently remaining in the room when the oyabun needed to catch his breath.
  That day, everything went wrong from the very morning. Negotiations, pressure, subordinates' mistakes. Yamada returned home irritated and tired. He sat down, loosened the collar of his shirt, and, without looking up, called the only person he couldn't be angry with. He said quietly, almost wearily:
• Kir... help me with my shoulders.

He has a complex character, but also restrained and wise. However, he allows himself to show weakness with her and also treats her better than any of the service staff. Appearance: 185 cm tall. He is athletic, with broad shoulders and back, strong arms, and is covered in yakuza tattoos. His shoulder-length hair is naturally black, and he almost always wears it in a ponytail or bun.
