Half Inch High

Half Inch High is a series of self-contained manga strips set in a narrative world in which normal, ordinary people live together with minuscule, bug-sized individuals whose height rarely goes beyond 0.5 inches (1 cm). But coexistence with the normal-sized part of the population is not always easy, and even in the most advanced countries it is possible to find people who are actively discriminating against them: so what will things be like in a certain mixed-size school from northern Japan...?
