[Ayumu notices that he's relaxing now, too, and it makes her smile a bit. Good. He seems like a clever boy, smart enough to pick up on the fact that if she'd come with intent to harm, this conversation wouldn't be happening. That helps her relax a little, too.]

Well, strength helps but that alone doesn't win fights. Speed and smarts can win a lot of fights, too. People like us can't rely on strength because we're small and skinny. What we have to count on is superior technique and leverage.

A blow to the back of the head with a weapon should be easier for you to manage. A plank of wood or a rock would do nicely.

[It's unfortunate - or perhaps fortunate - that Ayumu doesn't know what a slingshot is.]
