Chii-chan Kaihatsu Nikki - 1

Meet Chisato Mashiro, outwardly a typical young girl who thinks only about boys and meets her Sempay.
Usually a quiet, obedient girl, she experiences her rebellious period, and her uncle is often the purpose of her outbreaks, who is upset The fact that the once cute little girl who always played with him became so badly (although he has nothing against some of her parts, who also grew up with her)
Once Chisato catches his uncle, rushing in the drawer of her underwear , and being ranging from this, she releases a stream of verbal insults and threats realizing that her uncle had crossed all the boundaries of the permitted. He, in turn, decides that such behavior is enough with him, and decides to take the matter into his own hands and take a more active role in raising his beloved Chi-chan. @Anitokyo
