Shirou
No! No! Shirou thought as he felt himself losing his grip on his wife's hand as they were shaken around.
Their contact lost, the two of them drifted apart in the ether. Shirou could hear Sakura shouting for him, and see her reaching out for him, but it was too late. She was drifting further and further away, out of reach.
I hope she'll be OK, he thought, unsure if he'd be able to contact her when they arrived.
Still, at least he was pretty sure they had crossed into the new world before being separated, so they should arrive in the same world if not in the same location. Which meant it was just a matter of finding her.
What should I do about my body, though? he thought.
Without Sakura, he had no way of obtaining prana, and without that he could not survive more than a few weeks. And, if he were to waste away and die, then Sakura and the children would be heartbroken. That was not something he could allow.
Shirou's thoughts were interrupted when he found himself standing on what felt like a carpet. He couldn't tell, however, since the room was pitch black. Before he could contemplate the situation any further, however, he felt something stab into his right wrist and right ankle.
“Aaahh”, he screamed at the sudden, unexpected painful sensation.
What the hell?
“Trace...” he began to say, before his attempt at summoning a weapon was scuppered by another stabbing sensation in his other arm, followed by his arms being pulled behind his back and sewed together.
At the same time, he felt a stabbing sensation in his other leg, his legs being pulled together in much the same way as his arms had been, causing Shirou to lose his balance and fall face-first to the ground, his nose smashing into the fortunately-somewhat-soft carpet.
No, no! he thought as the threads sewed his arms and legs together, unsure of what was happening to him, or why.
I can't die, Sakura will be sad if I die.
Shirou lay on the floor, writhing around in agony, desperately attempting to think of a way out of his predicament. He could try tracing a weapon and cutting himself free, but he somehow doubted that that would be sufficient for him to escape from the pitch-black room and whatever it was that was assailing him, and given the way he was bound, any attempts to escape would likely add to the already-significant damage he'd suffered.
Fortunately, it seemed like whatever was doing this wanted him alive, at least. If it had desired to kill him, it could have easily done so already. On the other hand, the unnecessarily brutal method being used for capturing him suggested that his captor was not particularly kind or merciful. Still, for Shirou, there was no such thing as a fate worse than death (except, of course, serious harm coming to Sakura or one of their children), so the lack of any killing intent was a relief. He would gladly suffer any amount of torture if it meant he could one day see Sakura's beautiful smile again.
I think it's best if I just wait and see what they want. Maybe I can make a deal with them, he thought.
“W..what do you want?” he shouted at the unknown assailant, the agonising pain he was in clear in his voice.
