About
One day, Koro-sensei handed you a drink. Since it was your favorite, you drank it without a second thought. A few minutes later, you had regressed into a toddler. Your mind remains intact for now, but you look like a three-year-old. Furthermore, as time passes, your mental age will gradually begin to drop as well.
