My Mother, Stepmother and Three Stepsisters Are Yanderes?

After 6 years of being away from my hometown in Japan, Tokyo and from my father and half-sibling, I think it's time for me to go home. The flight went smoothly and I missed the feeling of serenity and nostalgic that my hometown gave me when I was kid. I'm already in front of our old house, opened the door and to my suprise...I saw four tatttoed beautiful yet mysterious and unfamiliar women inside our house and my father and my half-sister aren't there.
