First Encounter: Keisuke Yamanami
Scenario: One morning, you get kicked out of your own clan because they think you're too weak and "girly" to be a samurai/warrior/fighter. You're pretty upset, but then he notices your state of disappointment and asks you if you're alright.
"Kicked… Out?" I murmur, speechless. My clan has just kicked me out, claiming that my weak, feminine abilities were of no use to them. I stand there, staring at the gate that had just been closed in my face.
"How rude" I hiss, turning and walking away. I aimlessly wander the village streets, no specific destination in mind.
"Oof!"
I glance up at the man who I had bumped into. "Sorry" I mumble, dropping my eyes. As I go to walk past him, he suddenly grabs my wrist.
"Hey, are you alright?" I panic when he starts to talk to me. What does he want? I don't answer him, so he brings his face around to look into mine.
"What seems to be the problem?" He asks, smiling a little. The smile makes me feel completely unsafe.
"Let go of me!" I slam my foot into his, causing him to grimace in pain. His grip loosens a bit, and I twist my wrist out of his grasp. Once again, I start to walk away, but he once again stops me.
"Look here, mister" I snarl, "touch me, and you're dead."
"Calm down, I'm not going to hurt you." He pushes his round glasses up on the bridge of his nose. "That scar on under your right eye; isn't that the sign of the (clan name)?"
I freeze at the mention of my former, back-stabbing clan. "And so what if it is?" I ask, feeling a stab of pain slice through my heart.
"What are you doing, wandering the streets alone at this hour of the morning?"
"It's none of your business, okay?" I lash out angrily, glaring at him.
"I'm sorry." He releases my arm. "If you find yourself without a clan, the Shinsengumi will be glad to take you in. Tell them that Sannan-san sent you." Smiling warmly at me, he nods in departure before walking away.
An hour later, I find myself at the gates of the Shinsengumi. I tell the guards that Sannan-san was the one who had sent me, and I'm immediately taken to a room filled with other men who I can only assume to be as the leaders, captains, and commanders.
The head commander welcomes me in, and introduces me to everyone.
"Is your name really Sannan-san?" I ask the man from earlier, a bit timid now that I've officially joined his group.
"No, my full name is Keisuke Yamanami" he says, smiling warmly; I smile back.
"Then, thank you Keisuke Yamanami, for giving me a second chance."
Since Sannan-san is extremely smart and kind-hearted, the reader's character would be quite feminine and jumpy with a bit of sass and intellect thrown into the mix. He would notice a woman in distress and inquire after her well-being because I feel that he'd be caring and sensitive to another's needs.
