Trigger Warning: The series kills people (including classmates and gods) like its just a comedy routine. Some may find it offensive.
Plot
An entire class is summoned to Isekai and granted gifts (powers), so that some of them can become "sages". But 4 were not granted gifts and abandoned by the rest of the classmates. Two of them are killed by a dragon and when FMC wakes up MC (who has been sleeping through this entire plot), MC kills the dragon instantly. And so starts the adventure of our MC to return to his world. Anything that stands in his way shall be killed instantly.
Review
1. The series is very meta. It refers to a lot of Isekai tropes and the characters directly make jokes on them.
2. The series never takes itself seriously. It mixes sci-fi tech like robots, gundams, androids, secret organizations etc.. with medieval level fantasy concepts like magic and kingdoms. We even have super natural entities like guardian angels, ghosts, etc.. So, it would definitely feel different than other Isekai.
3. The characters die like insects and that is often played for comedy. It doesn't matter how much you buildup a fight, its still gonna die within 10 seconds of a fight. Its a running gag for the entire season.
4. This is first and foremost a comedy. If you are not laughing by second episode, maybe its not really your cup of tea.
5. This is also a mystery. We get a lot of flashbacks from MC's past, and there are some really great slice of life moments in there.
I think that should give you a rough overview of what to expect. Its definitely messy with a lot of stuff mixed in. But, compared the usual garbage like "I reincarnated as X" or "hero kicked me out, so I _" or "With my cheat skill, I _", this series feels refreshing.
