"A Noble Phantasm!?" Rider's face turns pale the moment I tell him what I think just happened. I, on the other hand, regain my cool (as much as my migraine lets me) and nod to him.
"Yes, apparently. It's too early to say anything for sure because I'm having difficulties reading the data from the runes set inside Shinto... That bound field is somehow jamming them. But since I felt it at that one moment, I'm rather sure it was a large and sudden surge of prana which activated it. Also, I believe you've heard that crackling sound a few moments ago." While his face remains dumbfounded, his eyes clear up a bit and he gives back a nod. "Your puzzled look is justified. I was also struck unprepared." I reply with a smirk as I walk to the sofa and pick up my bag. "I mean, who would have thought some Servant would have revealed their strongest weapon on the first day? But it's also unsettling... Their Master must be very confident in their abilities if he let something like that happen." I walk up to the door and open them, ready to leave. "Shall we?" I gesture him to come.
His reaction though... is unexpected. A wide grin appears on his face, replacing the look of worry as he stretches his arms behind his back. His black shirt unbuttoned at the top dissapears in a flurry of white sparks, replaced by a simple white shirt coupled with a sleeveless vest. His trousers turn into baggy pants tied by a piece of rope around his waist and ankles, and a single unsheated saber with a beautifully crafted hilt appears in his left hand. He calmly ties it with the rope around his waist and speaks in a smirky tone. "I thought you'd never ask."
