Having found the room he'd take a peek inside and quickly tense up a little as he saw his instructor, Miss Chinoike. He wouldn't linger very long at the doorway though and would quickly find a place to sit, his eyes only briefly breaking contact with her location when he had to turn his back. He knew of the Chinoike clan's dojutsu, and while he couldn't recall the exact specifics of what kind of genjutsu it had power over, making eye to eye contact was almost never good. As such he bore his sight into her chest area, wondering why in the heck she'd be so unprofessional with her choice of clothing. Unfortunately for him, his answer would come in the form of his mental co-host.
"Oh wow, yeah I thought it was just me messing with your head but She really does radiate 'The Kage is my Bitch'. Such shame that a teacher that hot also happens to be someone you loathe. Truly that has to eat you up inside. I mean, there's a reason she kept her shirt unbuttoned, and it sure isn't because of unprofessionalism!"
Of all the times. At least it had the decency to not manifest and just speak inside his mind, but having to hear it make a meta-commentary on what he saw sucked. He also knew that the Id was right in regards to her clothing choice as well. Attempting to appeal to the more carnal desires of a person was one of many ways one could extract information from a target. It was also why he was attracted to weapons as a poor attempt to screw over his own Id. Sadly it hadn't quite worked as attempting to screw yourself over, even if it is a different part of yourself now attempting to kill your true personality and take over you body, is still yourself, and due to that he now-
"You! What is your name?"
Without skipping a beat he'd stand at attention and place his right fist over his heart while bringing his left behind him and holding the sword & scabbard with it. In his attempts to drown out his Id he'd lost track of time and hadn't realized class had just begun. Attempting to sound professional while trying to hide his obvious fear & surprise, he'd state his name a bit too loudly.
"M-Mōtimā Midori-Okō Kurama Ma'am!"
Why him why him??? Did she recognize him? Could she read minds? Did she catch him looking at her bosom? Sure she was good-looking, but was she like one of those spiders who seeked out those who were infatuated and ate them afterwards?? To any onlookers his face would turn several shades of red, while internally he could hear his Id laugh it's mostly nonexistent ass off.
