The official website for the [email protected] television anime began streaming the anime's second promotional video on Friday.

The story follows a hikikomori (shut-in) named Sasami who is unmotivated about even changing clothes or eating. Her brother Kamiomi takes care of her, even though she despises his slave-like nature. Sasami spends her days viewing the outside world via a "Brother Surveillance Tool" on her computer. In the outside world, the three beautiful Yagami sisters and Sasami's brother are in the middle of relationships worthy of a romantic comedy.

The new video gives the first preview of the voice cast:

Kana Asumi as Sasami Tsukuyomi, the hikikomori

Chiwa Saito as Tsurugi Yagami, the Yagamis' big sister who looks like a child but is as tall as an adult

Kana Hanazawa as Kagami Yagami, the middle sister and Sasami's always sleepy-looking classmate

Ai Nonaka as Tama Yagami, the little sister who is as tall as a child, but looks like an (well-endowed) adult

Houchu Ohtsuka as Kamiomi Tsukuyomi, Sasami's brother

Akiyuki Shinbo is teaming up again with his Madoka Magica and Bakemonogatari studio SHAFT to make the television anime of Akira's [email protected] light novel series. Katsuhiko Takayama (And Yet the Town Moves, Love, Election, & Chocolate) is in charge of the scripts, and Hiroki Harada (Romeo × Juliet, Yu-Gi-Oh! Zexal) is designing the characters.

After his earlier Kyōran Kazoku Nikki novels were adapted into anime in 2008, Akira launched the [email protected] light novel series in 2009. The ninth volume shipped in September.

The series will premiere on the TBS and BS-TBS channels in Japan on January 10.
