The Melancholy of Haruhi Suzumiya I

Kyon enters high school as a first year student and meets a strange girl by the name of Haruhi Suzumiya. During her class introduction, she states that she has no time for normal humans and asks that any time-travelers, aliens, or espers come out and join her. Interested in her, Kyon becomes the first person to solicit a normal conversation from Haruhi. This leads Haruhi to form the SOS Brigade.
