The blade catches him in the side. He falls, from surprise more than pain, but it's Naoto who cries out, and then—
He'll only remember it in snatches. There's a grin too wide. Naoto pointing his revolver. Someone speaks to him, and he understands the words, but they don't make sense ("Not so tough without your knives, huh? My son—").
Then a crack, and the voice goes away.
Someone's hurt, he thinks. He tries to stand, but there's a hand on his chest, keeping him down.
He stops trying only when he hears sirens.
