1) The author describes the MC as a "learning god" but never actually say what he was a learning god of. As for calligraphy, that was stated as the MC's hobby.
2) The cards gimmick is never delved into with any type of depth. Why are they necessary? How do they work? They don't seem to run on spiritual power because the MC has none. So are the words themselves spells? Then why do they need a mecha to activate? Why does a mecha enhanced by spell cards not fall apart since when moving beyond capacity. Why do you need a mecha to use summoning cards. The author never explains any of this and only tells us this is the complicated setting we are meant to believe.
3) Not only is the main gimmick not explained in enough detail, but the MC is never decribed beyond "Oriental teenager" - if this novel was written by a Chinese author the racism gauntlet would have been thrown. No characters looks are described much beyond the ML's eyes being green, you can guess the hair colour. And another character being blond. The MC is also not the only "Oriental teenager" around.
4) The MC goes off on bizarre tirades that last paragraphs explaining to other their logical falacies, because wasting time on minor grievances and petty nonsense is supposedly both smart and logical. This is a world with a "perfect" report system, which one would expect to deter foolish behaviour, but no.
5) Not only the MC, but many other characters talk about logic and reason in a very bizarre way, while doing very illogical things.
[collapse]In conclusion, the MC is seriously unlikable, and doesn't seem smart at all. He despises other people as not being good enough. And with a little success becomes vain and egotistical.
