I think you were a bit generous with your name calling my padawan
Sorry about the delay, 'tis the season for such things. z.z
Hmm.. Kenjutsu is an oft-forgotten field utilized by some ninja that is essentially 'swordsmanship'. Whereas taijutsu focuses on hand-to-hand combat, kenjutsu is weapon-based - utilizing one or more swords. It is one combat method theoretically subordinate to the umbrella term entitled bukijutsu, but the overwhelming prevalence of swords somewhat distinguishes the art. As a puppeteer, I personally find standard kenjutsu to be.. primitive in a sense, given my access to significantly more sophisticated tools. That said, I have some ideas for innovative styles I'd like to pursue once I've attained a legitimate grasp of the art. Now, I'd imagine a two-handed grip generates more power than a single-handed grip, albeit at the expense of greater rigidity and less versatility. The latter offers the swordsman a free hand to do any number of varying tasks.
Observing Ace-sensei shift into a preparative stance, Koumei obliges by removing his own katana from its sheath with his right hand. Opting for a simple offense, he lunges forward and raises his sword arm up, before bringing it down in a diagonal slice. The motion would bring damage to Ace-sensei's left shoulder and then continue on until the blade reaches the right of his hip. All the while, he keeps the sheath of his blade ready to be used as a defense.
Koumei dashes toward Ace-sensei's clone, with chokutō firmly grasped within his dominanthand. Upon close proximity to his target, he shifts his right arm in such a way that the very same hand transitions to a position near his left shoulder, before promptly lashing out with the chokutō's handle, so as to momentarily stun the clone. Without faltering for even an instant, he chains the initial attack into a subsequent taijutsu sequence. He does so by first executing a simple front kick to the clone's chin with his right leg that knocks it into the air, then continues with a counterclockwise motion that terminates in a powerful jump spinning side kick with his left leg, aimed at the solar plexus. The force of the latter blow is sufficient enough in force to send Ace-sensei's clone flying in the direction of a nearby tree, with Koumei swiftly covering the newly made distance between his target in time to punch it into the tree. "Hmm.. a two-handed grip might've had more power, but only insofar as the first attack, thus not really changing much given a modest margin of difference in initial power. Moreover, this is a primarily taijutsu-orientated maneuver affected by leg strength."
