Okay, it seems Kiritsugu was approved, so I'll use him for the first time. :3
Darkened times, Kiritsugu had begun a new venture in his life. Teaching. Something he never thought he'd do. However, he was now going to pass on some knowledge, something that not many knew. A specific skill, known as Kaito's Taijutsu, derived from the legendary Kaito, a man who was a master of Taijutsu. The Sage of Mind, Body and Soul. Kiritsugu shook his head as he got lost in thought, and with his dark attire, he made his way to the training field. Kiritsugu could taste the chakra signature from afar.
"He's already here.."
He thought. No worries, he was prepared. His hair was messy as usual, and his demeanor, serious.
"Manasseth, was it? Let's get straight to it. Kaito's Taijutsu, a very rare skill. What do you know about it?"
He asks, having already read a bit on the man. Kiritsugu always did research before facing someone, or in this case, teaching someone.
