Rurouni Kenshin is the story of a revolutionary patriot fighting to conceal his bloody past in the new Meiji era of Japan. Battosai Himura's role in the revolution was so infamous that it earned him the title ‘Hitokiri' (Manslayer). To put that fearful name and his past behind him, Himura returned to his original name of Kenshin, reversing the blade on his sword to make it non-lethal, swearing to never take another life and beginning again as an ordinary rurouni (wandering samurai). He meets Kaoru Kamiya, a spirited girl who runs the local dojo and is the first of several friends to accept him for who he is, not who he was. But Kenshin's past will not leave him alone, and with old rivals remerging, groups attempting to shatter the hard earned peace, and those with desire to face the legendary Battousai, all chasing after Kenshin, can he protect those he cares about and still maintain his oath?

Also, both manga are full of action, adventure, romance, and take place in a historical setting. If you enjoyed one, you will enjoy the other.
