Made in Abyss is set in the town of Orth, built around the Abyss, an enormous and largely unexplored pit full of strange creatures and ancient relics. Cave raiders who explore it are ranked by the colour of their whistle, with White Whistles at the top. The story follows Riko, an orphan who dreams of becoming a White Whistle like her missing mother, and Reg, a robot boy she finds in the pit. Together they descend layer by layer and meet explorers, guardians and residents of the deep. This page covers 12 characters, from the travelling party to the people they meet across both TV seasons. Profiles describe each character as introduced, without spoilers for later events. Note that despite its soft art style, the series contains intense and sometimes disturbing scenes.
