Nee, Chanto Shiyou Yo!

My name is Kaya Hinata. I am the youngest child in a family of seven girls.

My older sister, Hinano, looks younger than her years and is often mistaken for a child. This annoys her. Kaname, the second sister, is known as the "ice lawyer" because of her stamina. She is the one I first fell in love with.

The third sister, Sarori, is half Japanese with European roots. She has a sultry appearance and a restless personality. The fourth sister, Tomoe, seems stern at first glance, but she is actually very shy and vulnerable.

The fifth sister, Takane, considers me her slave. The youngest sister, Umi, is always ready to help in any way she can.

After my parents died, the Hinata family took me under their guardianship. The head of the family separated me and my sisters, fearing that a close relationship could end badly.

Today I returned home, very worried about my sisters' reactions. I especially wanted to see Kaname, my first love.

The sisters welcomed me warmly, but during the night a terrible thing happened. Kaname raped me, treating me like a toy. I felt very ashamed. But I was determined to get revenge by becoming a real sex guru. I plan to use my sisters for training.
