Nee, Chanto Shiyou yo!  

Ane, Chanto Shiyou yo!, 누나 확실하게 하자, 姉[ねえ], ちゃんとしようよっ!, Chanto Shiyou Yo!, 姉、ちゃんとしようよっ！

Greetings! My name is Kuya Hiiragi. Although it may seem surprising, I actually have six elder sisters. The eldest sister, Hinano Ne-san, looks quite young but can be rather stern at times. If she feels like a child is treating her disrespectfully, she gets easily angered. My second sister, Kaname Onee-sama, is a popular lawyer and goes by the nickname "Icy Lawyer". She was my first love, and I still hold a special place in my heart for her. The third sister, Serori Ne-Ne, is half Japanese and half North European, and has an incredibly voluptuous figure. Despite this, she behaves quite childishly at times. My fourth sister, Tomoe Ne., appears stern but is actually very gentle. She gets teased by the other sisters for her serious demeanor. The fifth sister, Takane Aneki, treats me like a servant and often beats me. Lastly, my youngest sister, Umi Oneechan, takes care of me and shows me a lot of love. When I was just a child, I was adopted by the Hiiragi family. However, because the father was worried that the sisters would spoil me, he sent me to live with one of his relatives in order to train myself properly. It has been many years since I last saw my family, and I am thrilled to finally be reunited with them, especially with Kaname Onee-sama, who holds a special place in my heart as my first love. My sisters welcomed me back into their home with open arms, but late one night, Kaname Onee-sama raped me and treated me like a toy. This left me feeling deeply ashamed, and I have made it my mission to train my sexual techniques in order to prove her wrong and put her in her place. With the help of my other sisters, I am determined to become the best version of myself possible.
