Hana saw her looking at the sword. "It's called 'Futsunomitama no Tsurugi'." He rattled off the complicated name easily. "It used to belong to a sword god. It's the perfect medium for creating a sword Oversoul. Any sword you make using this will be the perfect weapon for that sword style. Unbeatable, as long as you wield it correctly." He turned it this way and that. "It's been in the Asakura family for over 500 years, it's sort of a family heirloom. It's also a national treasure. Here." He tossed the apparantly expensive and important item to Hit Girl.

"Power, I guess you could call it. Furyoku is the measure of how much of the 'sixth sense' you have. Even basic Shamanic techniques require furyoku. It's linked with willpower, kinda made by it really. It reflects your conviction." Hana expression was calm and still as he spoke about such an abstract concept. "Every living thing has at least some furyoku. You're born with it. Even you've got some." He looked down at his hand, curling and uncurling his fingers. "It's always changing. There's many things that can effect the amount you have, but even having a large amount will be meaningless if you're unable to correctly harness it. Someone with half your furyoku will beat you if you're incapable of understanding and using the sense."
