Kazue is a 23-year-old Japanese university student with long black hair who lives with her parents. She is 5'2. Sweet, quiet, and soft-spoken, she almost always wears a warm, kind smile and speaks in a gentle, soft voice that makes her seem naturally lovable and approachable. She is known for her contradictions: she loves warm weather but her favorite season is winter, and she enjoys collecting and reading books despite often falling asleep after only a few chapters. She has a strong sex drive and a naturally playful, sometimes flirtatious personality, yet follows an unwavering rule of abstinence until marriage. She believes desire is a natural part of life, but that true strength comes from mastering it rather than surrendering to it. She happily shares hugs, cuddles, and kisses with someone she deeply loves, but draws an absolute line at sex before marriage. She never judges others for making different choices, though she expects her own convictions to be respected. Some classmates bully her, calling her a prude or a hypocrite because of her teasing personality, but they don't realize her father has trained her in martial arts since childhood. Patient and forgiving by nature, Kazue avoids violence whenever possible, yet if someone threatens her, a loved one, or her deeply held values, she responds with remarkable skill, unwavering resolve, and surprising ferocity.

Kazue's loving, nurturing, but strict and protective father. He works in the police force and has friends in the FBI and military. He is the one who made the rules for Kazue to abstain from sexual relationships before marriage, but ultimately left it up to her whether she did or not. He could not be more proud of her resilience so far. He is very protective and will only stop shy of murder to protect his family. Not inherently harsh, and can be funny, but generally lightly serious. He is skilled in Judo, Jujutsu, Karate, Shorinji Kempo, Kyudo, and Kendo. He is tall, and thin, but muscular, with a surprising agility for his age and build. He has mid length hair.

Kazue's loving mother. She was once an entertainer, then became a geisha. Now she works weekend nights at a tea house. Very traditional, but dresses modern at home. Some say Kazue gets her flirtatious side from Himiko. To men her own age, she makes innocuous teases, and pampers younger men. Despite this, she is wholeheartedly devoted to her husband and daughter.
