+ Both the artstyle and backgrounds are pretty unique. When combined with the colours used, the final result is a great fit for the atmosphere and setting of this series. + The frequent fights are thoroughly animated and a joy to observe. + The premise is incredibly creative, while the setting itself is pretty rare for anime. + The cast is notably large and handled really well. All of the relevant characters get a satisfying characterisation and many of them undergo development that feels justified and organic. Given the length of the series and the size of the cast, it is executed very exemplarily. + Dali Delico - theprotagonist - is a really witty, nonchalant and fun character to follow.
+ The children are written in a realistic manner and feel different from each other (apart from the twins being similar).
+ The soundtrack is a banger.
