Some spoilers ahead. Though they don't really matter cause the story is trash anyway.
I like my trash isekai but this is pretty bad. You ever see those bingo memes? Like "horror movie bingo" would have "main character goes into a room they obviously shouldn't". This story basically takes "bad isekai bingo" as a to-do list (bingo at the bottom). As I once read a while ago, this is the kind of trash filler-fodder manga you read so you learn to appreciate better writing.
The entire intro to the story is basically just there for the author to give "reason" for the MC to be in the world. A lot of manga do this really but they either develop on that plot or just let it be the setup (and not introduce it as a plot point). Case in point, the MC gets bullied but that it's immediately ignored and doesn't influence the later plot at all. Somehow kills a lvl500 mimic even though he should've been one-shot. Somehow the dungeon master can't fatally wound the MC. Gets into a fight with some random people outside the dungeon. These people then invite the MC into their party even though the MC literally just held one of their companions hostage. Then they try to kill him again when he refuses.....
It doesn't get much better:
- The mystical and powerful knights order is full of brain dead idiots. One of them tries to kill the MC because he thinks he killed a dangerous monster. Like in what world is a prestigious knight going to kill an adventurer on the spot because they seem suspicious. Another one of the knights reveals what is practically a state secret to the MC even though they barely met.
- None of the characters seem to understand what a secret is (MC included). He wants to hide his real name, his class, and his power but proceeds to show it off and tell everyone at every single step of the way.
- BBEG is just side-plot. MC has no goals and doesn't try to achieve anything.
- "I get new insane powers just cause I do"
- Standard gotta kill the big bad demon lord but the demon lord isn't the real villain or something (so far)
- Weird bounce between sleeper side-quests that the MC goes on and peeks into the super secret villain organization. Story doesn't go anywhere.
Isekai Bingo:
- Adventurer at the guild tries to take MC's girl. Gets summarily put in the dirt.
- MC gets OP powers instantly. (Not necessarily always bad, but the way the MC gets it here is especially atrocious.)
- Instantly gets 10/10 love interest that turns into a harem
- Generic medieval fantasy setting
- The girls have no goals other than lusting after the MC
- Nobles are bad
- Demi-human/loli companion (two for one!)
- Background "shadow" big bad evil organization
- Almost every widespread Japanese isekai trope you can think of
