The Cain Saga Vol 3

From the VIZ Media edition

More secrets of the Hargreaves legacy are revealed! Cain meets two people destined to impact the future of the family--one might be a vampire, and the other is much closer to Cain than he could imagine. And in a psychologically twisted tale of identity crisis, "Ellie in Summer Clothes," a young girl wakes up to discover she's not who or what she thought she was at all.
