This show utilizes essential anime elements of fan service, comedy and action. Every character is likeable, including the antagonists because each of them are unique and bizarre in their own way, but that's not to say how some of them do have some questionable traits, however it helps moves the plot forward.
Adult humor us inevitable, given this show is geared towards teens and young adults, it's not usually empty and can be used to point out some of the characters personalities. E.i. unfaithful spouses and sadistic parents.
Power of friendship trope is highly subtle, usually put into action rather than turning it into a cringeworthy motivational speech that nearly takes up half the episode like other anime I know (looking at you, Fairy Tail.) It also leads to some very heartwarming, and maybe tearjerking moments, including the concept of family and bonding that leads to powering up.
Comedy is decent, running gag is the protagonist's bestie interfering during a fight to either give praise or motivate her, being funny and or a driving force to the plot.
World building pretty straightforward, but some questions are left unanswered, just not enough to being the plot down. I do like the elements of capitalism and caste system being used to build the plot and the setting.
Plot is also straightforward with its share of twists and revelations that keeps teh viewers hooked viewers hooked for more episode such that they end up binge watching it on Netflix (guilty as charged)
I would definitely recommend
