Futuristic post-war Japan is divided into four military regions, each led by conflicting nations trying to gain complete control over the country. While the Boundary War—fought with the help of humanoid mecha weapons called AMAIM—has long been over, the rivalry between these factions is still ongoing, and, as a result, the Japanese are heavily oppressed.

Amou Shiiba, a 16-year-old orphan boy who is secretly rebuilding an abandoned AMAIM named Kenbu, stumbles upon Gai, an autonomous AI in need of battery power. By choosing to help one another, Amou and Gai find themselves at the center of a disaster, and Amou is labeled a terrorist and cast out of society. Even so, Amou refuses to remain idle in the face of injustice, and he embarks on a long journey rife with struggle and companionship. His aim transitions from leading a peaceful life to liberating the Japanese people.

We know, we know. The Gundam franchise that started way back in 1979, that was a massive success of a franchise that tied in all the anime, movies, Gunpla merchandise, video games, heck even the long-lasting relationship and sponsorship with Bandai, that spawned THE generation of what the mecha genre should be defined as. Years later, with the many iterations of Mobile Suit Gundam, and with the recent purchase and closure of defunct studio Xebec to turn that around as yet another subsidiary studio of yours by the name of Sunrise Beyond, the Gundam franchise continued from there with the ...

Kyoukai Senki is so painfully bland I had to drag myself to finish it. The constant "Amou saves the day" and slice of life like episodes dragged it down too much. The plot progresses so slowly, and though I tried to be patient and give it a chance, it just wasn't done well at all. It was exciting to see a mecha series that would focus on 2D animation and completely ditch CGI, but it did an awful job in doing that. Lots of times the animation is Scarlet Nexus tier bad in that it uses still frame fights with flashy lights and cheap effects ...

Mixed Feelings
Sir Killalot’s Japan.

I was surprised at how hyped I felt by the end of the first episode of AMAIM. It establishes it's world and military problems well, Amou and Gai, a super AI meeting and helping each other even under the reality of becoming terrorists was well set up and animation seemed to be pretty good.
The real problem with AMAIM is it’s pacing. After around the 5th episode the story hops from mecha, military action to a strange mesh between a slice of life and boy scouts genre… thing. It doesn’t really work.

Amou is a pretty okay lead protagonist. He’s shy and indecisive, but ...
