Far in the future, the lifeforms known as Gadoll suddenly arose as a threat to humanity. The last surviving humans on Earth confine themselves to the Tank, a lower district in the giant mobile fortress Deca-Dence. While the Gears who live on the upper floors are warriors who go out to fight as part of the Power, most Tankers are content to provide support from the backlines, butchering Gadoll meat and reinforcing defenses. Natsume is among those who would rather go to the front lines; undeterred by her prosthetic right arm, she seeks to join the small number of Tanker soldiers who join the Gears in combat.

But despite her peers at the orphanage each receiving their work assignments, Natsume’s enlistment to the Power remains unapproved. In the meantime, she begins a job as a cleaner in an armor repair team led by the hard-nosed and apathetic Kaburagi, who seems to be more than he lets on. Though initially cold to his idealistic subordinate, he soon recognizes in her the potential to upset the status quo of the world. As Natsume’s new mentor, Kaburagi prepares her for the special and unique role as a game-changing bug in the system.

One of the best works of dystopian fiction I've ever had the pleasure of watching. Title has a neat dual meaning. The beginning is incredibly well-done. While many write off the ending as "convenient", the commitment to the final decision involving one of the main trope characters arguably denies that. Fumiyuki did an awesome job with the OST as well.

My only rationale for not rating this 10/10 is due to the ending being on the weaker side, as well as the characters beginning to make less-believable decisions that I feel were not objectively cohesive with their originally defined predispositions. Kurita's characters usually appeal to me ...

Mixed Feelings
Deca-Dence = Kabaneri of the Iron Fortress = Knights of Sidonia = Attack on Titan. Yes, there's a "twist" (if you can even call it that) that gets revealed very early on that makes this setup technically different from the aforementioned anime that this is clearly copying, but at the end of the day this anime is far more similar to its influences than it is in any way original and it simply never escapes that. It also doesn't help matters that the female lead here, Natsume, looks like several other characters from different anime as well. Throughout the entirety of my viewing experience of ...

*Spoilers Ahead*

Deca-Dence is best described as an ambitious amalgamation of Gurren Lagann, Attack on Titan, and The Matrix, that still falls quite short of the quality, impact, and timelessness those stories have. The story is, on the face of it, an adventurous and creative concept. Giant robots fighting giant monsters is a tried-and-true formula, and not just in the Mecha genre. The world that is constructed here is engaging and lore-filled, which often distracts from some of the drawbacks the show has on display. However, despite the dynamic nature of the story, I only found myself enjoying half the show, and that is this anime's ...
