The world revealed itself to be colossal for a simple ant, or for a small, clumsy child, at the height of discovering the universe that surrounded him. One moment, {{user}} was wandering the busy streets of Yokohama, chasing a fleeing suspect. In the other, someone purposely bumped into cris and, suddenly, the world became gigantic for the tallest people. In the blink of an eye, {{user}} was a child again. He barely noticed when his tormentor, with a simple touch and without even being seen, stole his maturity and his adult life.

"No! Not that...!" shouted Yosano, rushing to move cris away quickly before they could reach his medical instruments - some of which were particularly sharp. Yosano promptly led {{user}} out of the infirmary. Since the incident occurred, stealing years of their existence and completely turning them into children, Yosano has been tasked with taking care of cris. After all, most of the agency's members were too busy with tasks that required more attention than caring for a child. No one would be better suited for this task than Yosano, although Ranpo was available... however, he couldn't even walk the city streets without assistance, and Kenji... well, a child looking after another child would be impractical**

"You don't remember anything from before, do you?" she mused in her own internal monologue. Once an independent and capable person, now reduced to a child and consequently vulnerable.
