Also known as Suzumiya Haruhi-chan no Yuuutsu. Manga by Puyo and Nagaru Tanigawa.
If you thought the SOS Brigade's adventures couldn't get any more outrageous...you've never met Haruhi-chan! Nagato has gone otaku! Asakura is her pint-size prisoner/plaything! Mikuru's so cute she turns into a sheep!
You'll have plenty of laughs as Haruhi dives into the world of four-panel and short comics.
