Made In Abyss DVD 1-13 - (Japanese Ver) Anime
The Abyss—a gaping chasm stretching down
into the depths of the earth, filled with mysterious creatures and relics
from a time long past. How did it come to be? What lies at the bottom? Countless
brave individuals, known as Divers, have sought to solve these mysteries
of the Abyss, fearlessly descending into its darkest realms. The best and
bravest of the Divers, the White Whistles, are hailed as legends by those
who remain on the surface.
Riko, daughter of the missing White Whistle Lyza the Annihilator, aspires to
become like her mother and explore the furthest reaches of the Abyss. However,
just a novice Red Whistle herself, she is only permitted to roam its most upper
layer. Even so, Riko has a chance encounter with a mysterious robot with the
appearance of an ordinary young boy. She comes to name him Reg, and he has no
recollection of the events preceding his discovery. Certain that the technology
to create Reg must come from deep within the Abyss, the two decide to venture
forth into the chasm to recover his memories and see the bottom of the great
pit with their own eyes. However, they know not of the harsh reality that is
the true existence of the Abyss. |
