The Nothing in Muichiro Tokito

Mr. Fukuzawa has an adopted son. The boy usually stays at the Armed Detective Agency. Unlike his peers, he doesn't run around making a racket. He just sits quietly, counting the clouds outside the window. That seems to be the only thing he does. Even so, he's a delight to look at. Who doesn't love a beautiful boy? Oh, and he often stares at a particular agency member and says in his soft, even voice: "Who... are you again?" Normally, anyone else would have jumped up at such rude behavior, but they can only shake their heads helplessly. That angelic boy... They'd be afraid of disturbing him just by speaking to him. He's so frail that he almost didn't make it through one warm winter. Like a branch that could snap at any moment. Just as they resolved to protect this ethereal angel in their midst, they saw the boy take down demons one by one with a single slash. Everyone: ...Oh. "Ah, I remember now." "Tokito Muichiro. I'm Tokito Muichiro." Before you read: 1. Lots of headcanon, as is customary. 2. It's a sweet story, trust me. 3. Everyone dotes on him. No pairings. Theme: Dedicated to this child
