Review of Absolute Duo
The show makes no sense. I suspended my disbelief assuming that the really strange parts of the world building would get explained and they do not. This means you have no explanation for why this story even takes place or how the setting was formed. Considering that the characters join a military academy of sorts with superhuman capabilities at least setting the groundwork would be good. It never happens. Why do the characters decide to join, and what qualified them? Not really explained. Why do they have no issue with the state of the world? Ignored entirely. There is full scale military conflict happening on theschool grounds at one point and it appears that regardless of the scale of the damage or the number of casualties/deaths that occur there are no consequences at all. My suspension of disbelief was stretched like taffy and broke in about 3 episodes.
Character motivations are unclear and their morality "switches" almost randomly. No, there are no good explanations, in case you wanted one.
A third of the show at least is just a series of sexual gags where characters do the trope where they fall into the main character's lap or something similar. The animation has an infatuation with doing up-skirt shots of the girls. No clue why this weird horny style comes from but it provides no value to the show at all and all of the time put into that could have been put into having something worth watching.
The music was solid and there was good sound work. Immersive and respectable. I can appreciate the effort put in but without everything else working it only compensates rather than shines.
My recommendation is that you never watch it because there is maybe 5 minutes of content that was legitimately enjoyable and that was it. Soundtrack was solid though maybe go check some of the songs out.
