Onji:
[chuckles] So, it's the Unmasked Warrior's turn to meet her doom. Isn't this a riot - the Battle of the Elderly?

Genkai:
Why don't you drop your tired act and lose the disguise? You won't be fooling anyone else with that crappy mask.

Onji:
Hmm?

Kurama:
Disguise?

Genkai:
I don't know who you are, but you're no old man. And in case you haven't noticed, I'm not the kind of person who will underestimate you based on false age.

Onji:
You've got a pretty sharp eye there for such an ugly, worn, past-its-prime body. You're the first to notice. I even masked my own energy. You see, disguise is one of my favorite hobbies.

[Onji tears off half his face]

Juri:
Ugh-gh-gh-gh.

Onji:
To be brutally honest, there are few things I find more repulsive than old people. That moth ball smell that hovers around them makes me absolutely wretch. That's why I chose this get-up: I thought wearing the skin of something I abhorred would all the more fuel my rage.
