[X] Let's see what you can do. Take it away!
There is some token protest and questioning as to how you got backstage, but for the most part no one cares as long as you stay out of the way. The elderly stunt-master is just happy someone wants to talk to him instead of the actors for once. "Sure, kid, I'll show you a trick or two."
And
does he. He throws around the burly rigger he ropes into helping like the guy's made of paper.
"You've gotta remember to watch the blade, not their hands - very important. The weapon can be in
either hand. Once I met a fellow in the circus who could even hold knives between his toes, so watch out if your opponent is barefoot." He winks at you.
He shows you how to turn people's grips on kunai and swords against them, and even demonstrates a breakdown of how to break someone's arm or wrist to get them to let go. When he sets you loose on his 'lovely assistant Saburo', it's less than two minutes before he pronounces the lesson ended.
"Thanks for your time," you say, ducking your head. You're a little disappointed you couldn't learn anything more complicated, but hey, he's a busy guy and you have to get back to mom.
"Mm," he replies, looking at you for a moment, his expression unreadable. Finally nodding, as if coming to a decision, he hands you a business card. "If you ever find ninja-ing doesn't agree with you, that's my address in the capital. I run a self-defense school for noblewomen and courtesans and their fathers are always complaining about all my assistants being male."
"... I didn't say I was a shinobi," you say.
He just laughs.
But then, he didn't say he was, either.
You grin.
"Thanks for the invite, jii-san. Maybe I'll stop in for a visit sometime." You run for the door. "Abayo!"

"Who're you calling jii-san?! My mental age is young!"
As you emerge back in the lobby, scanning the crowd for mom, you're surprised to suddenly feel her hand in yours. You barely have a moment to look up at her in surprise before she's dragging you (and, with her other hand, Ami) out of the theatre.
You shoot Ami an inquiring look, but she shakes her head.
Mom vetos a late-night soak when you suggest it, and sends the two of you to bed immediately after you fold your dresses and pack them away.
"What the hell happened when I was 'in the bathroom'?" you whisper when you and Ami are finally alone.
Ami sighs. "That lady, Oshibe-san, your mom called her, showed up and had a conversation with your mom."
"Oshibe... that was the name of that woman she and Kurioka talked about this morning."
"She said something about how the next game had been scheduled, and asked if she'd be sending a substitute."
You frown. "A game?"
"Yeah." Ami rolls onto her side to face you in the dark. "Is your mom always... like that when she's mad?"
You shudder reflexively. "You mean the yuki-onna routine? Yeah. Dad's the same way."
"I can't believe the lady just laughed it off," Ami says, sounding a little creeped out. "I wasn't even on the receiving end and I was nervous; normal civilian women don't usually give off killing intent like that."
Now you're worried.
"What did this Oshibe look like?" Blah. Why can't everyone be a sensor? Normal people's senses are always so unclear on whether someone's dangerous or not.
Ami gets what you mean. "She didn't look like a kunoichi; not even a genjutsu specialist would have arms that soft."
Which means she's either a really fucking
good genjutsu specialist, she was under a henge (Ami isn't great with details, she might have missed it), or she's some new, non-shinobi type of dangerous person.
"Wait," Ami says, remembering something. "Her eyes were like yours."
"What? She was a Yamanaka?" The pupil-less eye thing is particular to the main line of the family; that narrows down the list of who she could be quite a bit.
Ami frowns, thinking back. "I don't think so... I mean, she didn't look like your family otherwise. Her hair was black, not blonde or red. And she was wearing it loose; I've never seen any Yamanaka wear their hair down."
"Could she have been a Branch House Hyuuga?" Your mind is trending in a direction that you'd really wish it'd cut out until all hope is definitely lost.
She snorts. "I think I'd have remembered seeing a green-eyed Hyuuga around town."
Aaaand there goes your last hope; there're lots of normal dark-eyed people who seem not to have pupils, but aside from the Hyuuga, you and your dad, you've never met anyone with light-coloured pupil-less eyes.
Except for Mom.
"Did she say anything else?" you ask.
Ami makes noises to the effect that she did, but Ami doesn't remember the specifics. "They used a lot of metaphors and stuff," she says, embarrassed. "It was over my head a bit."
You sigh.
Well. You were the one who was so curious about why your mother was banished. Looks like the mystery's brought itself to you.
In the morning, you
[X] Go about the day as normal. It's really unlikely Mom's going to want to talk about this now and you'll just spoil the rest of your vacation. (Skip to next set of options)
[X] Talk to Mom before breakfast.
[X] Talk to Mom after dinner.
What's on tap for this fine Saturday?
[X] It's the peak day of the market! Let's go check it out!
[X] Der Kestle! Maybe there's a dungeon with traps you can test!
