A fun series that handles a fairly simple and common isekai premise with only relatively slight twists. The overall plot is fairly simple following the MC as he finds new monsters and enemies to fight and eat growing stronger along the way and growing a group around himself. The story does slowly get slightly more mysterious but not much has come of that aspect as of yet though it is clearly setting things up for later. The characters are solid if simple none having significant depth but still largely fun to watch and read about. They have clear and straightforward dynamics between them which while not unique or complex are easy to understand and enjoyable. The protagonist in particular is fairly simple but could be a breath of fresh air for those used to extremely whitebread niceguy isekai protagonists. He is fairly curt at times but actually grows to care about the people around him despite being actually decisive when needed and having clear motivations both in wanting to grow stronger and why he wants to grow stronger. He doesnt fall into wimpy MC vibes that many more modern isekai do as he actually is a driving force in the story of his own will and is trying to accomplish things. The art is unremarkable but decidedly solid somewhat unique in going a bit more for grittiness at times. During the battle and action scenes the art occasionally shows weakness as it doesnt lend itself to overly clear fights or choreography but it also doesnt try to do those things instead electing for individually solid shots and results. One thing that does need to be warned is that the series covers some heavy topics and shows some dark things at times so be warned. In particular it doesnt shy away from showing fairly graphic wounds and deaths and due to the core premise has lots of consumption of sentient beings. Also it handles some more directly sensitive content particularly: However it does handle that topic roughly as well as it was likely going to and doesnt glorify or sexualize it. There also is some generally sexual content but its not directly shown on screen and is relatively inobtrusive overall. Overall this manga is nothing extremely special but it is a fun series to read that wont leave you bored if you enjoy fantasy series with powerful protagonists that grow in unique ways powerwise. Dont go into this looking for your next favorite story full of deep characters and plots or an expansive and detailed world but you dont need to completely turn your brain off as it has enough character/plot depth to keep things reasonable and enough worldbuilding to keep the story feeling grounded in a setting. The series should also be recognized for likely being a major player in actually starting some now common tropes in isekai the story format and concept is noticeably similar to that of the everpopular Slime isekai with the MC gaining the abilities of what they eat starting as a basic trash mob and growing to lead a group but it needs to be noted that Re:Monster started in 2012 while Slime started in 2014 making Slime the one whod have copied here though the two series are distinct enough in their details that Id say its more derivative than copying in this case. Fans of Slime will likely enjoy this series as well though the overall tone is a bit darker here.
