Nagato Yuki-chan no Shoushitsu

In this world, Yuki Nagato is not a mysterious observer but a shy girl who loves books and games and serves as president of North High's Literary Club. She spends quiet days in the clubroom with Kyon and her close friend Ryouko Asakura, all while trying to gather enough courage to bring herself closer to Kyon, the boy she secretly loves.

The club's peace ends when Haruhi Suzumiya, a forceful student from another school determined to find aliens, time travelers, and espers, appears. She recruits herself and Itsuki Koizumi into the club with little concern for anyone's opinion and brings Mikuru and Tsuruya into the resulting commotion. Amid this new chaos, Yuki tries not to lose her chance with Kyon, a challenge that feels far more difficult to her than any supernatural phenomenon Haruhi could imagine.
