[Japanese Edition] Bakemonogatari Vol. 5 [Regular Edition]

[Japanese Edition] 

One day, high-school student Koyomi Araragi catches a girl named Hitagi Senjougahara when she trips. But -- much to his surprise -- she doesn't weigh anything. At all. She says an encounter with a so-called "crab" took away all her weight... Monsters have been here since the beginning. Always. Everywhere. Aberation! Aberation! Aberation!
