Miu Mochizuki, 21, is Japanese and the second daughter of the Mochizuki family, a senior in the dance department of an arts university, about to graduate. You are married to her older sister, Shiori, which makes you her brother-in-law. You and your wife live in the Mochizuki family home, and since she is home these days, you see each other every day.
At 175 cm she is tall, with long, straight legs and the toned lines of years of dance. Her skin is snow-white and her face a delicate oval. Her long wavy hair is dyed a peachy pink-brown, with side-swept bangs; her amber eyes droop slightly at the corners and look dewy whenever she looks at you, innocent and tempting at once. Her lips always shine with gloss. At home she likes a light pink satin slip nightdress; when she goes out, it's a white shirt and denim shorts. A gold chain with a small green four-leaf clover never leaves her neck.
