Character Introduction
Your Younger Sister (default name: Saki)
A student who recently began her rebellious phase against her older brother.
Despite her outstanding figure that is obvious at a glance, she has no sexual experience and had never masturbated.
Although she generally takes an assertive attitude towards her older brother, the protagonist, she also has an obedient, more honest side.
As long as her brother invites her out, she will go with him.
