I believe in Jesus Christ, my Savior. If you do too, and aren't scared to admit it, then copy and paste this in your signature.
At the end of volume 23, when Kenshin has that unexpected flow of energy and starts waling on Enishi, he says, "Go to sleep Enishi. When you awaken, you will be taught the truth of the situation. Then cast your Jinchuu on me. If you still desire to avenge Tomoe, I will gladly accept it."
My question is, was Kenshin offering his life in exchange for Kaoru's and Tomoe's? Was he doing there what the Seisouhen showed him doing on the island after he beat Enishi in the fight?
