Yoshimitsu watches as Fuu stares into his eyes. This look on her face was cool, calm, and collect. But she suddenly swung her sword, and released chakra from it that cut a tree in half. That was pretty freaking awesome! But since that is raw chakra coming from the blade, it is weak to all elemental chakra right? So any C-rank elemental ninjutsu can counter it, as long as the description fits with common sense? Yoshimitsu starts molding his physical and spiritual energy to create chakra within himself. As he does this, Yoshimitsu grips his sword in his right hand, not breaking eye contact with Fuu. Yoshimitsu channels the chakra into his sword and horizontally swings it at the same tree Fuu did. Yoshimitsu made sure it was not a huge, wide arc so Fuu wouldn't get hit. As he swung, the chakra he channeled into the blade left it, and with shape manipulation, Yoshimitsu willed the chakra to form a crescent shape. Like that?
