@Kampfarsch Given that Keigo is Yukari's uncle and Keigo is the son of the previous Yakuza boss(Keigo yelled Papa during the flashback in chapter 3), then that makes Yukari the boss's granddaughter. Thus, the boss reincarnated as his own granddaughter not daughter. I could still be wrong, though. The author hasn't done character sheets or anything of the like yet, so I'm simply basing all this off of what's available so far.
