Like many with a haunted and troubled past, he tries his best to lead a simple, humble life with his friends Kaoru, Yahiko, Sanosuke and Megumi. But, such ghosts catch up with him eventually, and not only put his life at risk, but those he cares about at risk as well. And, as fate would have it, he is put to his ultimate test many times to stop enemies who have absolutely no conscience when it comes to killing, but use that weakness against Kenshin since they know he doesn't want to. For the record, this is a personal favorite series of mine. With one of the most intriguing casts of characters and the emotional and personal conflicts they deal with Kenshin and what his past has done and what it could do, you really get riveted into watching.
Fight scenes are spectacular with great description on each of the attacks and styles.
If you decide to watch, be prepared for a long haul, but it's worth every penny.
