Hiko quotes from Rurouni Kenshin

Even when I wield my sword according to the teachings of Hiten Mitsurugi-Ryu, too many times I cannot save a soul. I kill and kill, and still the villains, like maggots, spring from the corpse of a Japan decomposing. There will be more and more acts like this...and all I can do is bury the victims.

I thought I taught you...Swords are weapons. The way of swords is the way to kill. However you try to dress it up in phony righteousness, killing is your truth.

[When asked who he is by a brigand] There is no point in naming myself to those who are about to die.

Man or woman, to attain buddhahood without knowing the taste of good sake is a crime. A good sake is the least I can do.

[a boy gives his name as Shinta] For Kenkaku or "sword arts," that's far too gentle. From now on, your name is to be "Kenshin." I shall also give you my most precious knowledge.

If you're to overcome this, you need to remember what you just saw. You need the will to live.
