So, while the story is mostly enjoyable, I have been having trouble with the mindset of the MC. he was raised as an assassin. From 3 years old. While I don't know what a child assassin mindset would be like...I would assume he was trained to be patient, listen, be aware, take in information before acting, and would generally be colder and more indifferent to people. Unfortunately, while he has his moments of brilliance in planning and fighting, his overall attitude, intelligence, social perception, and thoughtfulness are equivalent to some of the worst Japanese isekai protagonist s I have ever read. In other words...he's dumber than a baked potato. Then there are the side characters...everyone has this laissez faire, forgetful attitude that makes it near impossible to treat all but a few of the characters with any sort of seriousness...no matter their importance or power level. That, and the translation quality make me rate this book lower than it could be.
