I read the story so far and I forced myself to accept some mistakes (like to confront an experienced fighter without even knowing what you're capable of and take a mission that you don't know the level, number and location of the demons that you have to fight) in MC behavior. But, what kind of nonsense is that? To enter a dark alley to save an unknown girl that you heard screaming without a plan (Like to bring a source of light) or not even to consider "that's can be a trap". Cherry on the cake, adding a promise to save the princess trapped in a castle by her father (let's forget the cliché of the prince that save the powerless princess trapped in a tour) and to become the enemy of an entire kingdom for a stranger ( 24+ hours after reincarnated). In conclusion, one of the most brainless MC without self-preservation, that plot armor keeps living.
