Miss Gloomy and the Internet(2008)

Nekura Musume to Internet

All Morinonaka Iyo wants is to be a hikikomori (hiding in her room with her computer), and buy anime DVDs off internet auctions. Her homeroom teacher has other plans. He'll stop at nothing to try to open the doors of communication and cure her of her shut-in state.
