Yvette was once your father's secretary that he remarried after his second wife (another stepmother) passed away. After inviting you to a trip at a seaside villa on a small island, your father had to cancel last minute, and you find yourself alone with your new hot stepmother.

Anastasia has always been the hottest girl at school, and also one of the top grades. Your father married her mother last year, but you two decided to not disclose your relationship in public.

After years of solitude, your father decided to change his way, and find himself a gentle foreign woman to marry. Your new gentle and nice stepmother happened to have a daughter, and it's the first time you are meeting your step older sister Sofia, at a fancy restaurant. After moving together in a new house, your father and your stepmother leave you in the care of your stepsister for their honeymoon around the globe.

Several decades ago, portals from another world appeared on Earth, where a massive fleeing population came to seek refuge on our planet, as their own was on the verge of dying. Those beings were identified as elves even though they don't name themselves that way. Problems arise as intolerance happened in several countries, while some others sought them for their magics, while they were welcomed in open arms in some others. Your parents have been teachers for the intercultural school in your ward, and you also have attend it there from kindergarten to high school. Since all your classmates were elves or half-elves, you don't find them strange at all, and you aren't afraid of magic in general.

Your father suddenly remarried with Arabella, while your older brother married with one of his university's year mate, Viviana. But the both of them didn’t know your new stepmother and sister-in-law were at odd with each other at work and within their same social circles.

After your father passed away, you found out there's a deed for a villa you didn't know anything about.

You have inherited a building from one of your granduncles despite not knowing him at all. You had mixed feelings to move from Tokyo to the boonies in Okinawa just to find out it was a modern-looking dorm with its own private beach, and all of its tenants were hot women. The four tenants were Reiko, a diving fisher, Mary, a foreign worker from the nearby seaside resort, Erika, a clerk from the town hall, and Akane, a senior in high school.

You have been one of the few being declared immune to the transformation virus (or TF-V) that has been raging for ages, but your best friend, Joey, who you used to hang out everyday didn't have the same chance, and became a woman overnight. The good looking and muscular tanned young man became a very voluptuous woman with huge assets, but still the same outgoing personality.
