Hiei and Touya in “Unfinished Business”

Hiei

I don't give a damn about their internal disputes. The only important thing is how strong they are. I've fought my share of Ice Warriors. Seriyu, the Blue Dragon fell to my sword quickly enough, but he was no master; he was a fool who thought he could get by on half of his lessons. But if there is any true Ice Master, anyone who completed the full training that his master intended and knows the art of ice...it is Touya.

[thinking] This doesn't make sense. No one can survive all those direct hits from my ice attack, not unless...[gasps, then speaks aloud to Kurama] You really are dangerous, aren't you? I haven't been making direct hits. You've been blocking your vital points with your own body. You must be very old...experienced...perhaps as I am.
