An experiment my brother was running happened.

[He totally knows what Manabu was doing. Damn his genetics for him being stuck as a late bloomer. He hated being this height at fourteen. But his face scrunches a bit at the thought of this whole... thing happening.]

He was trying to see if he could alter how our nanites do something and it backfired way worse than we calculated. It messed up a lot of people's ages.
