This is a biased response as I only bothered the first half of the episode and skipped to the ending of ep20 to drop.

I am a person who doesn't watch anime as I don't have the time nor dedication to. I admit that I have managed to watch harem anime both knowingly and unknowingly, so my anime taste is poor. (Although, I watch them to pass the time, not analyize in any way)

However, from the first half episode, I thought it might be a intresting concept but then turn into 8th grade delusions about being the top.

Forwarded to ep 20/S1, 2 girls seem to be fighting him, and he doesn't break a sweat!

I know most harems are filled with OP Protaginists (Ayato from The Asterisk War [Don't watch] ), but they atleast struggle some way in the first half. This sequence felt boring and plain and I couldn't stand watching this.

Then? He puts a bubble and dissapears.

Throughout this, I never even smiled at any of the scenes, I just was confused (Why change your concept? How did he get strong? Limitations?). I had heard this anime was funny, but was dissapointed. I'd rather watch Princess Connect, a (non-harem) anime that made me belly laugh, or Overlord, a series I never watched, but had heard its similarity in a MAL review after thinking how this was up here.

If you enjoyied this, I won't rain on your parade, but I will never recommend this anime to anyone even with my low standards.

Take care, TesterJ.
