"Yuusuke... Dammit Yuusuke, listen to me! Everyone has to fight with time to find their place before their inevitable death. Toguro... he ran away from that fight. Don't you ever do the same. No human is ever a one man show. Every decision that you make will affect the countless people who care about you. Do you understand? You can't be a cocky kid anymore."

"Even as a child, I found tremendous pleasure in spilling my enemy's blood. Their screams of agony were my music. Once I learned that my mother's frozen tear drop was valuable, I began wearing in open sight of everyone, hoping their greed would entice them to challenge me, thus giving me the opportunity for my next kill."

"*to Urameshi* Sacrificing your life to save billions of others. You've lit our torches and I won't let your death be in vain... even if it means I'll be joining you soon."
