Kaoru died at the hands of Enishi. Kenshin died a few years later, her loss and a love unfulfilled stained his soul. His heart searched for her even when he lost his memory of her. A series of inter-connected bite-sized one-shots.
[One-Shot] He's been alone before. He doesn't know when, or how, but he has. Fortunately, that rare kind of people always seem to fish him out of the sea of sorrow. Sequel is in progress.
