Reimu smiled as the demon surrendered.  She didn't let down her guard at all, wary of trickery, but she didn't attack either.  "Very well, just leave your things on the ground and walk away.  I've no desire to get any closer to you," she said as she fished in her pouch for the potion, taking advantage of the momentary pause in battle to heal herself.  If he tried to attack her again, she wouldn't hesitate to attack him.
