The Disappearance of Nagato Yuki-chan I
As Ryoko suspected, Yuki IS different from who she used to be. While Ryoko and Kyon are worried that Yuki might behave so differently that their classmates may figure it out, she plays the role of the old Yuki just fine and no one notices anything.

The Disappearance of Nagato Yuki-chan
This spin-off of the Haruhi Suzumiya series takes place in the world of the "Disappearance" arc of the original novels, focusing on the high school life (and romance!) of a tentative and bashful Yuki Nagato quite unlike the one you've come to know and love through the usual exploits of the SOS Brigade... but no less charming!
As the shy head of the Literature Club, Nagato has had a hard time recruiting members. Her close friend Ryoko Asakura supports her in this. Drafting Kyon, she eventually meets up with Haruhi Suzumiya, Tsuruya, Mikuru Asahina and Itsuki Koizumi, and has to put up with their hijinks while trying to romance Kyon. Asakura seems ambivalent about the latter prospect.
