In the first half there is a little bit of fan service the worst is barbie doll nudy of Cecil Suu after she take a shower. She does has important roll in series but she comes off as intj and does not show a lot emotion. the first half of the series is ok. it starts of in post apocalypse world with monster of the week plot.
those plots usually feel Cliche. how ever the plot thickens by mid point of the series. The 2nd half the fan service is toned down which is good thing because usually with action anime it just get in the way of the story. I really wanting to know what happens at the end most of 2nd half episodes.
our hero is intp personality with all strengths and flaws that come with it. Which found likeable and relatable being intp my self. How ever I am no super genius. I like interactions between him and Chloe. Chloe is and ESFJ and why she bring up family contract so much at first. the other characters are fleshed out too and likable. how ever the show at time spends too much time on small things than the action.
