Speed-You-Up X (ハヤクウゴケールX, Hayaku Ugokēru Ekkusu) are a type of experimental magical medicine that alter a person's sense of time.


Speed-You-Up X are small cylindrical pills whose halves are of different colors. One pill can alter a person's sense of time such that one second seems like thirty. From an observer's perspective, they basically speed up the user, hence their name. These pills are still under development.[1]
