Shades of Reality — Nobuhiro Watsuki

It began with a sin, committed by Kenshin, back during his bloody days as hitokiri or a government-sanctioned slayer of men. Although stopping most of the assassins who still come seeking revenge should be easy enough, what of the innocent--Sanosuke and Yahiko (Kenshin's comrades), everyone at Akabeko Inn (Kenshin's friends), Kaoru (Kenshin's...?). For once there was another love in Kenshin's life, one which--given his nature--must by definition have been tragic. Can Kenshin escape the shades of his past, and find the will to fight for the real world--for the living--for reality?!
