Yuichi Mitsui, an ordinary university student. He is currently living alone to attend college.
She isn’t there … or rather, my sister’s super love ♪
Therefore, he chose a university far from his parents’ house because he wanted to get rid of his younger sister, saying, “If nothing is done, it will be a forbidden act.”
However, one day during the summer vacation, Yuichi’s beloved sister visits.
The younger sister, who I saw for the first time in two years, wore a plump bust, a constricted waist, and a tight buttocks while maintaining her loveliness.
Hana, a younger sister with this strongest visual sense. But she had one drawback.
The only downside is that it’s … a ridiculous idiot.
If you walk three steps, you will forget everything you learned, you can hardly read Chinese characters, and he can not operate the remote control with three or more switches.
Yuichi decides to follow the thorny path in order to raise his younger sister, Baika, who is in danger of social life, into a good adult.
