Made in Abyss (Japanese: Meido in Abisu) is a Japanese manga series by Akihito Tsukushi and published by Takeshobo. It has been serialized online in Takeshobo’s digital publication Web Comic Gamma since 2012 and has been collected into seven tankōbon volumes. An orphaned girl named Riko lives in the Belchero Orphanage in the town of Orth. The town surrounds a strange, giant hole going deep into the Earth, which is commonly called the Abyss. The Abyss harbors artifacts and remnants of a civilization long gone, and is, therefore, the popular hunting spot for so-called Cave Raiders, who undertake arduous and dangerous descents into the mist-filled pit to recover whatever relics they can find. Returning from the Abyss can be dangerous as “the Curse of the Abyss,” a mysterious and potentially fatal malady, manifests upon ascension. The deeper one goes, the more acute the effects of the curse; few who have descended into the lower regions have returned to tell of their experiences. Some legendary Cave Raiders earn the title of White Whistle, one of them being Riko’s mother, Lyza.
