Tomoe leaned back somewhat and ruffled his hair further with a sigh. He let the girl process her thoughts on the matter, as it seemed to hit her all at once like a speeding wagon. That was about the kind of reaction he expected, and while a part of him wished that maybe he could've just kept it a secret, it would've been impossible to hide forever. Little Rinni did seem to shut down however, which concerned Tomoe after a few moments of being unresponsive.
"Uh... yo, you good? Ya seem a bit out of it. You need to lie down or somethin'?", Tomoe questioned, leaning in closer and snapping his fingers in the space between them to test her reflexes.
It seemed as if the wily, or perhaps simply naive fox had caused her to stumble forward. The Joyan's warrior instinct kicked in for a brief moment as he used his arms and body weight to keep her steady while she tripped forward. Due to the reflexes needed to react in such a way and Tomoe's own incompetence and inexperience when it came to helping people avoid injury, he grasped too hard with his left hand and ended up squeezing her right shoulder.
Seeming to regain her own balance and wake up afterwards, the touch seemed to put her into a state of pain. This stood out as odd to Tomoe, and he began to piece together that perhaps she was hiding an injury beneath the armor and clothing. It was none of his business, but he felt the need to make sure anyway.
"Oh, shit. I'm still gettin' used to this whole side of the job, sorry. Are you hurt or somethin'?", Tomoe inquired further while pointing to her shoulder, partially to deflect the topic from him being a 'guild master' and the other part due to something resembling concern - not that he'd admit it or anything.
Inevitably, though, the conversation would eventually direct itself back towards his status as a 'guild master' and what that implied. That put a pit in his stomach but he'd ride it out. And then Rinni delivered her own verbal bullet in two parts: she wanted to join the guild, and she referred to him as 'master'. Both were things he wasn't expecting, and on the inside he reeled a bit from the girl's sudden burst of enthusiasm.
Tomoe had a small coughing fit by choking on his saliva while trying to hold in his surprise, quickly clearing his throat to save face in front of... his pupil? Ally? He didn't know. He wasn't used to getting new allies, really. After a moment he composed himself, his posture straightening in a way that he might envision Aegis to do.
"Nothing other than showing a desire to help your fellow people and beyond. We're the kind that protects, but also attack as needed. Hunt, in some cases. Above all though, to see justice done and to put yourself into danger so that others don't need to.", Tomoe spoke with an authoritative and formal tone, but quickly sighed and dropped the serious act, ceasing his stance reminiscent of a military general to become casual once again; almost as if he were mimicking something he'd seen done before.
"And while that's all good and well and true... don't get it twisted, but I just see myself as one of 'em. I ain't a leader and I don't really like this position either, to be honest. No false advertising. It will be dangerous. This line of work can be fun, but it doesn't come without its share of threats. In fact, most of it is threats.", the crimson cutthroat continued, back to a speech pattern more closely resembling his true self.
"But if you come along, we'll make sure you get all the knowledge and training ya could possibly want before we send ya out somewhere dangerous. Not gonna send someone in blind, 'n all that. Or hell, even alone. Some of us like to travel in groups at times."
After finishing his explanation, Tomoe's features warmed somewhat. Before him was an aspiring young adventurer, and if she wanted to join, he would do what he could to see her grow into the type of person she wanted to. His speech may have been equal parts reassuring and brutally honest, but he didn't like the idea of luring in people who didn't know what they were getting into. If such things were enough to deter the girl, she'd be all the better for it in the long run.
"If you still wanna join, then the only real tests are those of the pen. Paperwork 'n all that, gotta keep it official. And just to make sure you ain't crazy. Though considering this line of work at your age, maybe ya are!", Tomoe finished his final clarification with a playful wink, simultaneously teasing her and impressed by her even thinking about such a life at her age.
Afterwards, he went silent to await her answer in full. He stood with a relaxed posture, not wanting to play at being formal even with the truth revealed.
