Recommendations Isekai/portal with op mc that makes sense

[TheJudger]

I want an isekai/portal with an op mc, and what has to have in it:

- An unique power that only the MC has
- Good dialogues
- Mc has to be more logical than emotional

What i don't want it to have:

- Harem
- Forced romance/illogical romance(like when the girl/the guy fall in love for literal no reason the second that they see each other)
- Passive MC(the type that doesn't have their own opinion and just follows what their group wants him to do)
- Hero Mc(Now, don't misundertand me, i don't want they to be only an evil Mc, they can be good, but not an ideal hero like superman that wants to save anyone and sacrifices himself to do it, it is too unreal, human beings are egoist, and i want him to be the most realistic possible on this aspect)
- An second MC that is just unbearable and their only reason to exist is to piss off the primary MC and the readers

What i don't mind to have:

- Romance
- Gender Bender
- Cliche story construction(as long as it has good execution)
- Non Human Mc(I personally like it)

I feel that everything that MelasD has written works here

Had one, but then I realized it wasn't a unique power.
