>>5787532As for Naoki, he's gingerly picking up some shuriken like he's secretly expecting that they'll be burning hot freezing cold enough to possibly damage his fingers... Well, his wooden fingers, because he tries to use his wooden hands at first. You notice that the dexterity of that hand is pretty limited, its fingers twitching and spasming as they try and fail to grab one. Eventually he just uses his good arm and gets ready.
"Alright... Stand back."
He throws a shuriken. It glides depressingly into the dirt. He picks up another one. It flies wide left by like a mile and lands in a bush. Not only was he EXTREMELY bad at this, but he had an uneasy look about doing as well, like he was completely terrified they were going to frisbee back towards him and cut him in half. You look at his wooden arm. The fuma shuriken. Wooden arm. Fuma shuriken. He's from the Fuma clan. Ah.
"Naoki, this might sound rude, so feel free to not answer, but... did a fuma shuriken take your arm."
He winces as if he's in intense agony, stops what he's doing, and turns to look at you as if he's guilty about it.
"... I've always been strong. Because of that, my clan taught me to use fuma shuriken when I was a little boy. Very little. I had the strength to sail one like it was made of paper, but... I lacked control. One day I was practicing, I sent the fuma away, but it came back for me." He explains, reflexively rubbing his prosthetic. "I'm terrified of these things. I'm scared of anything that has a blade, especially something that can be thrown at me. Not just because I might get maimed again if they're used against me, but because if I use them against others I might hit an ally, a bystander, or even hurt an opponent in a way beyond what I intended. Part of the reason I studied taijutsu so aggressively is because I never wanted to feel that unsafe in the face of danger again, but I just can't get over it."
