Steven has declared a unit of measurement. Sometime during the blur that was my vacation in Japan, I found something that I think measures up:
In addition to her high-school uniform, she enjoys busting out of a yukata, a miko outfit, frilly western dresses, and lacy lingerie. She’s the oldest of four sisters, and their Parents Are Traveling Abroad. And Our Hero has just moved in with them, having been Sent Down From The Mountains by his father to Become Stronger in the ways of the samurai.
She’s his new teacher.
Less than an hour after moving in, he manages to get into a Compromising Position with all three of her younger sisters at the same time.
Second sister is a bleached-blonde modern girl who’s sensitive about her small bust. Third sister is a sexually aggressive busty meganekko Gal doujin manga artist and junior high-school student. Fourth sister is a fourth-grader, who doesn’t appear to be a harem loli, fortunately, even if she does get dragged into the Wacky Hijinks.
