background art were also nice to look at. There were plenty of panoramics and art showcases that looked good. I'm not a fan of the earlier character anatomy and proportions as they looked a bit off in more than a few cases. Overall though I thought the art was good and is probably the best part about this manga.Panel Progression: 6/10There were a lot of flair in the panel layout. Some of the panel sequences were wild and nice to look at, especially during action and movement bits. The liberal use of panel cutting was much appreciated as well and added a nice touch to the generally bland storytelling. The pacing and clarity however were a bit off. The overall flow would change from a good pace to way too quick. Some details would be skipped as a result of the fluctuating pacing. Furthermore, there were some parts that could have used more time and clarity. I understand the time travel and whatnot twist, but the way the twist and its development were executed were a bit lacking and confusing.Characters: 5/10The characters were bland and one-dimensional. There was no foundation set for a lot of their motivations or personalities. The MC seemed like a cut and paste shounen teen aged boy. The female childhood friend was also cliche and nothing was done to give her any substance or diverge from the typical trope. Even the secondary female lead was typical and not much was done to make her valuable personally to the MC as well as to the overall plot and development of the story. The character designs were neat in a few bits. The older version of the MC looked cool and is a memorable look to me. The main monsters and villains too are a bit above average. Everyone else...very forgettable.Plot & Development: 5/10Average end-of-the world scenario with some gutsy pubescent MC. Either they're very much a human who tries to fight overwhelming odds with training and guts or they're some human who gains powers and goes down the slippery slope of fighting against the mental effects of dire state of the world and the power that may consume them. Luckily, this manga did exactly both of those which make it only average in terms of plot and development. Some examples of this setup are Dolly Kill Kill and Pygmalion which did essentially the exact same thing.Conclusion: 5/10A cop-out conclusion because either they had to end the series early or there wasn't enough foundation to keep the story going. It went from some linear standard development to some convoluted and poorly executed time travel development to finally a different timeline sort of thing. I feel that because the story couldn't be ended in a reasonably quick pace judging by how they initially introduced the idea of multiple hybrid-humans to where the were only able to defeat one by the end of the manga, the plot development went down this quick and easy, "Oh yeah, since we haven't actually gotten even close to saving the world in 114 chapters we're just going to save a different world in a stupid plan we're going to cover in 10 chapters."Overall: 6/10Average plot, below average development and conclusion, with average to impressive art. Only worth reading if you're really into the end-of-the-world setup.
