Currently it's good. MC really seems like someone who reincarnated and older. Seems level headed and mature which casts a big shadow on many other isekai stories. The downside is that he is limited by his age (11) but still it's quite promising considering his age constraints. Despite his limited freedom due to his age his proved and earned more leeway a freedom than most 15-17y olds.
And that's how you build a good reincarnator with memory intact, if you are a reincarnator in childs bodies that doesn't mean you will act like a child or be overly stupid it just means you will have to relive the hormonal disbalance age once again but booted with wisdom of a age it mostly affects you internally (you feel more emotions opposed to adult, it doesn't mean you will make stupid actions).
