One moment, he was sitting in the back seat with his brother and sister, watching them bicker over a toy. He couldn't understand what the big deal was, really...
And then the next moment, all he could hear was the screech of metal, agonized screams, and an inhuman roar. Something exploded near him, and all he could feel was pain across his throat.
There was a flash, white and yellow in the moonlight, and then there was the feeling of something being forced into him.
He screamed. He screamed in pain, in terror, trapped in the feeling of sensations no mortal body should feel.

... It took a long time for him to wake up, in a hospital bed with clean sheets and a scar around his throat. Minato gave him a scarf to hide the scar, and Minako told him stories of what she was doing all day until they let him out.
Their parents were dead, but even with that... something was different. Both more and less certain... but he couldn't put his finger on what it was. People shied away from him more... but his siblings stayed.
And that was enough for Ryoji.
