I want MC (preferably male) who uses brain and hard work to win no major plot armor, Should plan before a fight and should not be self-righteous hypocrite. Story should not have major plot hole or MC having power boosts just so he desires. No major advantage to MC would be good but not a necessity.
What nonsense is this? This is an aggregation site for realistic stories about magic and super powers. What you are describing is pure fantasy.
Try Altina the Sword Princess. MC is a weak dude who ends up becoming the strategist for a knight princess. Really good and tactical. Showcases the MCs knowledge pretty well
I go with Count of Monte Cristo in the run. If Female MC try some with imperial harem+black belly+ reincarnation or second chance.
first you need a writer with at least half those qualifications first .... but seriously for translated works it's a very short list, and some I tried had long chapters of ugh, just get on with things already...
well only what i can recommend is Live Dungeon!(MC is throw into game world where common sense is different from game) and My 【Repair】Skill Became an Almighty Cheat Skill, So I Thought I’d Open Up a Weapon Shop (well...slice of life?)
Well that's a really tall order. For translated works the only one I can think of is Pivot of the Sky. For English originals, that is much easier: Mother of Learning - amazing time loop story (highly recommend) Two Worlds - sci-fi military, starts off slow How to Avoid Death on a Daily Basis - gritty , realistic isekai Those are the ones I could find that fit, with no major advantage to the the MC. I have several others if you're interested in female MC or ok with the MC getting some magic power, etc., etc. from the start.
Only two so far have fit the bill Warlock of magus world Reverend Insanity PS: if you find more, please do share the wealth
