Misha is a little girl who lost her mother at an early age, and now lives with her father. Her father employs a maid named Tsubame, who was a former Self-Defense Force official, and is also a lolicon.
Washiwashi and Yui end up going into Misha’s very special room that no one is allowed to enter. Misha finds out that someone entered the room without permission and Tsubame immediately takes the blame, saying that she was the one who entered the room. Misha ends up going into the room and locking herself in. Yasuhiro gets a call about this and comes home. Why doesn’t Misha want anyone to ever enter that room?
