Deca-Dence S01

Many years have passed since humanity was brought to the brink of extinction by the sudden and unexpected appearance of unknown living creatures called "Gadoll". Those who remain now live in a mobile fortress called Deca-Dence, 3,000 meters high, built to protect themselves from the threat of Gadoll. The residents of Deca-Dence are divided into two groups: the Gears, warriors who fight against Gadoll every day, and the Tankers, those who do not have combat skills. One day, Natsume, a Tanker girl who dreams of becoming a Gear, meets Kaburagi, a gruff engineer who is one of the maintenance workers for Deca-Dence's armor. This accidental meeting between two seemingly opposing and different people - a cheerful girl who never gives up on her dreams and a realist who has given up on his own dreams - will ultimately shake the course of this world.
