Imouto Kansatsu Chu!

Synopsis

This is the first title by Sagittarius.

One day, Taketo’s younger sister Aoi broke his precious camera. However, she did not own up to the mistake one bit. While leafing through a camera catalogue still angry at her actions, he noticed a tiny camera which could be used for spying. He remembered that there was a crack in the wall of his closet and it was indeed still there when he checked it.

Looking into Aoi’s room, he saw Aoi on the bed reading an ecchi magazine. He was surprised to see this side of her and he had a bright idea: if he continues to spy on her and find out her weakness, then he might be able to release his grudge over her breaking his camera.
