Rurouni Kenshin: Reflection - Season 1 (2001)

Rurouni Kenshin is a wanderer, a lost soul, cursed to seek atonement for his life in the bloody trade of the samurai. During the long war to overthrow the corrupt government, he was known throughout all Japan as the Hitokiri Battousai ("sword-bearing master assassin"). But the end of the war has brought no peace to Kenshin, despite a vow to draw his sword only for the protection of those in need. Now his wife Kaoru steadfastly awaits his return, mourning his absence as well as that of their son, Kenji. Will Kenshin return before she dies of grief? The past meets the present fifteen years after Kenshin first left.
