Mizuki Yuiga
Age: Younger sister
Mizuki is Nariyuki's younger sister, though she's actually the oldest of his three siblings—she's got two younger brothers, Hazuki and Kazuki, below her. She's pretty much the glue holding the Yuiga household together, handling most of the cooking and cleaning while their parents are away working.
What's probably worth knowing is that she's got a pretty serious brother complex when it comes to Nariyuki. It's not subtle, and fans tend to notice it a lot. She's devoted to taking care of him, which ties into her whole role as the responsible one at home.
