- Hiei: I am fighting without purpose, falling back into a life of meaningless killing, a life of dishonor and cowardice. There is no more dignity in this sort of existence, so I must find honor in death.
- Hiei: Even as a child I found tremendous pleasure in spilling my enemies' blood. Their screams of agony were my music box. Once I realized my mother's frozen teardrop was highly valuable, I would purposefully wear it in clear sight of everyone, hoping their greed would entice them to challenge me, thus giving me the opportunity to take another life. I suppose I wanted to prove that my mother's people were right to abandon me.
- Hiei: Simultaneous death - the highest honor one fighter can give another.
- Hiei: My mother's people were a gloomy, timid race. It seemed as if ice was pumping through their veins instead of blood, like their spirits had been frozen and they were incapable of love. My impulse to kill faded: they were already dead.
