"Men sometimes only get stronger so they can conquer and destroy the weak." He said. He looked back before returning his gaze to Kohaku, "I'll train you."
"You aren't weak...and yes, I am...I need your help to protect Kairi and the clinic. I'll teach you all that I know in the art of swordsmanship..." Tesla told him
Kohaku rubbed the back of his hair, which was in need of a haircut. "You've taken care of Kairi and me and you've protected our clinic... You aren't such a bad.. Arrancar... And, well.. You know.. I guess I don't entirely hate you."
Tesla was honestly taken aback by this, "Really? Well, then..." He bowed slightly, "Arigatou...your intentions were always well placed so I never begrudged you."
Tesla stood straight and put his hand on Kohaku's head, pressing down, "I could be an asshole like my master taught me to be, if that'll suit your fancy."
