In the "Mondaiji" universe, 3 troubled teens from various parallel planes of time and existence are summoned into the world of the "Garden" to join in various "Gift Games" being held. But beneath this story that the trio was told to believe is a defeated community that needs their help to reestablish themselves again as a relevant part of their society, and reclaim their honor and dignity.
Making the character development within the series interesting is the different "abilities" each teen possessed that sets them apart from the other. Asuka is an aristocratic beauty that has the gift of "Authority", which gives her reign over the mind of those of weaker persuasion than her. Yoh is a quiet, yet very strong girl, that can talk to animals and use their abilities in her attacks and defenses. Izayoi is a smart guy but easily resorts to violence, has immense attack strength, and has an unknown ability that seems to nullify other gifts.
Seeing this anime much later this year, it seems to posses many fantasy anime tropes within itself. It has the "summoned into the fantasy world" premise like "KonoSuba" and "Re:Zero", the eclectic mix of of folklore and mythology like "Danmachi", with the same mind game attitude displayed in "No Game No Life".
It doesn't mean this title derived its plot from them (evident in earlier release date of this light novel than the others). The story of the series does makes it stand on its own. And their interactions either in light moments and the tense moments does balance out the situation, making the whole series amusing. There's not much twists in the plot, but it does give interesting points throughout the series making it a good selection for casual viewers and anime fans alike.
Production-wise, nothing is ground breaking, average at best, but it does serve the theme and the mood of the story well. I am not too fond of the opening and ending theme, though.
