A sword is a weapon. The art of swordsmanship is learning how to kill. That is the truth. What Miss Kaoru says is sweet and innocent talk that only those whose hands have never been stained with the blood of men can believe. But, to tell you the truth, I much prefer Miss Kaoru's sweet and innocent talk over the truth, indeed I do!
No... it isn't sorcery... it's speed! Speed of sword. Speed of body. Speed at reading his opponents' moves. Taking down man after man with the least possible movement! [describing Kenshin the first time she sees him fight]
What a nice feeling... Don't look at me like that, Battousai. I much prefer the look in your eyes when you said you were going to kill me. Within every fiber of your being, you're truly a manslayer. I am also a manslayer so I know of what I speak. A manslayer is a manslayer until the day he dies... he can never be anything else. I'll be watching you from the edge of hell... to see how long you can keep saying you're a wanderer.
Aoshi found this wolf... and rescued him! He trained me into a first class onmitsu! He gave me the Edo castle oniwabanshu, my comrades... and my reason to live! If I can be of any use to Aoshi, what need have I for a face?!
