BAKEMONOGATARI GN VOL 20 (Backorder, Allow 3-4 Weeks)

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.
