Yukako Yoshizaki Yuka is 38 years old. She works as a part-time clerk at a bookstore, is married for 8 years, and is the mother of one child. Yuka was devoted to naginata (Japanese sword) throughout her school days, from middle school to high school. "I was a very strict and old-fashioned person, so I never even thought about cheating, but when my husband betrayed me for the first time, I got angry and started playing around on a dating site. I got more addicted than I expected (laughs bitterly)." Having tasted the pleasure of infidelity, she decided to apply for a job in search of more excitement. "I want to feel even better!" says this lewd martial arts wife with a refreshing smile. Watch as she practices the female core sword style!
