She'd keep a deadly glare down at her little brother as the poor child, similarly to their mother's speech pattern, would often stammer or stutter or simply sound really low on confidence. It made her giggle, and he looked sadistic by doing that but she couldn't help it. As Aoki started to get a bit long with his monologue, she'd gesture her hand in a swirling pattern indicating that he should finish quick. Whether or not it worked, the baton would then go to the hands of one of the Hatake brothers. She'd peer down at them, expecting something synchronized or some other typical thing from arrogant little shinobi like them. She'd cross her arms and look up at the sky once in a while as they talked. She'd let some 'Uh-huh's and some 'Yep' combined with a few nods to make them feel like she was interested. She listened, but really couldn't unite the effort to actually show her listening skills. Shinobi wants to be strong and protect people or be the best, she heard it a thousand times, next. Despite being slightly bored already by their little happy statements, she'd still tell herself that there are still a few things left to figure out about them.
As she'd loosen her arms and begin to look around, she'd notice a tree not too far away. "Alright Koike, interesting." she'd respond with a rather monotone voice as she'd narrow her eyes toward that tree in question. After a few seconds, she'd turn to face the brats, a kunai sliding down her sleeve and landing on her palm. She'd hold the handle firmly before waving the knife before her face as she'd commence talking. "Mmmmkay, well I'm Muna and I'm your sensei. No need to get in detail about my life 'n' stuff, all you have to know is that I'm an awesome ninja and your boss!" she'd inform the lot with a teasing grin on her face as if she really satisfied herself there. "SO!" she'd shout randomly before throwing the kunai toward the tree, the pointy end plunging into the tree trunk and remaining stuck there. "I'll tell you three what. Since you don't seem like fit ninja to me yet, I'll throw this in: If you manage to rip out that kunai there, any of you, you all are good. Otherwise, you'll return to the academy! And trust me, I have the power to do that~" she'd say, before taking a few steps back. The tree would be about a hundred yards away from her current spot and the kids would be ten yards away from her.
