Bakemonogatari
The short stories in the two volumes of Bakemonogatari deal with a high school boy named Koyomi Araragi and strange students he encounters. ("Bakemonogatari" is a wordplay on the Japanese term bakemono for supernatural creatures and the term monogatari for stories.) One student, a girl named Hitagi Senjōgahara, almost literally falls into his lap, only to have him discover she has no weight.
