Sakura and Shirou
Shirou could do nothing but watch as the hyperactive squirrel girl zipped up to him and pulled the radio out of the boy's pocket, her movements too fast for him to stop her. Fortunately, though, she didn't do anything bad or stupid, instead actually being helpful and asking them further questions, to which the voice responded, asking them to follow the road to a nearby mansion.
Shirou took no time at all to make a decision. Shady or not, he couldn't simply ignore someone who may be in danger. So, he turned to the bodyguards.
"I can't ignore someone in need of help, so I will accept", Shirou said.
Sakura, meanwhile, knowing full well what decision Shirou would make, had already begun retracting her shadow tendrils, releasing the men who she had been holding.
"Well, it seems like you are no threat to the boy, so I see no reason to keep you restrained", she said.
Meanwhile, Shirou turned to the boy, who had turned his head away.
"OK, if I let go of your arm, will you follow us quietly?" he said, smiling gently. "I'd rather not have to drag you all the way there."
At the same time, Sakura walked up to Nanako.
"Will you come with us as well? You don't have to if you don't want to, but extra help is always welcome", she said with a kind smile.
