Zach no Koi

A vampire named Zach, close to completing his quest for a lost love, encounters an old house in a peaceful Japanese town. Inside, three individuals live— an elderly woman and her two granddaughters. Though vastly different in longevity and values, Zach chooses to reside with them. Over time, he gains insight into humanity by observing the lives of the people he grows attached to, particularly the woman he cherishes.
