Made in Abyss - S01

After surviving the brutal challenges of Idofront, Riko now has a White Whistle, which lets her descend to the Abyss's sixth layer, "The Capital of the Unreturned." Together with Reg and Nanachi, she starts to explore this uncharted domain, where the ruins of the promised Golden City lie. As the trio begins to adapt to the harsh environment, they soon run into dangerous creatures and treacherous landscapes. Their journey brings them to a village inhabited by strange beings called "hollows." Even with the creeping unease that greets them, the three press on to uncover the mysteries of the settlement and the long-lost legacies of the forgotten adventurers who once descended into the horrors of the unexplored Abyss.
