Made in Abyss: Fukaki Tamashii no Reimei

Riko, Reg, and Nanachi have an important mission ahead: to traverse the depths of the Abyss. But standing between them and their mission is the mysterious and sinister Bondrewd. He has been a part of the children's lives since they first suffered a tragic loss and has now reappeared, blocking the way to the fifth layer of the Abyss.

The group gets a glimmer of hope when they meet Prushka, Bondrewd's daughter, who may prove to be their only weakness. After becoming close to Prushka, the group works together to pass the sixth layer of the Abyss, facing Bondrewd's machinations along the way. With bravery and determination, Riko, Reg, Nanachi, and Prushka all fight for their mission to succeed.
