All the same, Mitsubachi was not so foolhardy as to confront his foe triumphantly; he could not beat an enemy who both Kamakiri and Chocho had failed to beat, not when she had assimilated their ninpo.
Kamakiri’s Mantis Talons.
Chocho’s Harlequin Butterfly.
Mitsubachi had seen her use both, and perfectly, when she dominated Chocho – it was unbelievable, but judging from what he had heard them say, this woman could adopt the moves of her opponents.
He could understand her learning the Harlequin Butterfly – that much was understandable. It was a question of how you walked. Mitsubachi might noe be able to cross an ocean, but he could keep it going for a few steps. The Mantis Talons, however, were another story. They demanded conditioning of the physiology. How could she make it look so easy, like it was nothing?
What a nightmare.
