"You're laughing at us even in your dreams!!" This was used to wake up his arrogant younger brother's girlfriend, followed by the forced sexual assault of the sleeping Mochizuki Rei (GVH-727).

One day, the sunny younger brother brought his girlfriend home. A cute and obedient girl with long black hair, "Toga-chan." On the surface, she's a very well-behaved child, but secretly she hates gloomy people and is extremely arrogant. Her older brother, "Izumi," and his friend, "Kota," are otaku from the very bottom of the school social hierarchy, and they plan to get revenge for her harsh words. They use aphrodisiacs to force "Toga-chan," who even mocks them in her dreams, into a deep sleep, and then rape her while she's unconscious!
