Genkai:
To be brutally honest you shouldn't be ready for this until another ten years of my training, even IF you DID come to me with unusual talent. It's a secret of my power - Spirit Wave Orb. For years I toiled with this creation - energy of the spirit and of the body concentrated into the smallest space. It is both part of and separate from me, and it could power a whole city block. Your test is to incorporate this into your own body and hope it doesn't tear you apart. The agony of this absorption is beyond words. It could go on for hours or days. If your body can not handle it, you will be eaten away from the inside out. And the only thing you will pray for is a quicker death.

Yusuke Urameshi:
Well, Hell, if it's gonna be that exciting, I might as well order TWO of 'em.
