This isekai is pretty good, cause you does'nt have to "know" how the MC could get transfer into isekai. But according to Cefiro phrase on last sentence in eps 12, i think Ike is got reincarnate as human in this world. Overall this anime is conclude warfare tactical kingdom, and Ike wanna create his kingdom with all types of race no matter what. If you watching this for batch i think you will looks the storyline kinda slow phase, but the plus is you can known what the MC is trying to think according to what circumstances is having problematic. Not so comprehensive but look so tightthe storyline will capable if you just wanna simply watch but does'nt want to think much, let us hear what MC are trying to do and we just look with different view what the cost and what the merit.
