I'm already not really an isekai power-fantasy kinda guy, but this seemed like bottom of the barrel even for the genre. I really liked the opening scene and was intrigued by the mystery of the main character's origins, but the isekai part seemed aggressively generic. I've heard it's supposed to be a comedy/parody type of vibe, but I couldn't even really identify when it was trying to make jokes. This premiere gets a 1/5 from me.

Like a lot of isekai first episodes, this was a good start.

I do like the evil-classmates-kill-em-all idea

But of course, it's all about whether the writing can sustain the quality and surprise.

Enjoyed the first episode, it looks fun enough to continue to watch to see where it goes, even if the overpowered-skills-in-an-isekai premise is so overdone by this point. Plus I know someone who is familiar with the source material and he is quite enthusiastic about it so hopefully it's been adapted well.
