The weird magic of AiPri is that it treats costume transformations like they're the most natural thing in the world, then builds genuine friendships around them. New characters keep arriving with their own ridiculous gimmicks, and instead of feeling bloated, the show gets looser and funnier with each one. By the time a mysterious princess shows up to run a contest nobody asked for, you're already invested enough that you want to see what ridiculous outfit she makes them wear next.

Himari and Mitsuki step into their second year at Paradise Private Academy, where a wave of new underclassmen, each with a strong personality of their own, makes school life livelier than ever. Over in the AiPri-Verse, new AiPri keep turning up, and everyone tries a brand new kind of Buzzrium Change. Meanwhile the mysterious Princess Ring Clover and her butler Shimitsuu are holding an AiPri contest, promising that the winner will become a celebrated Eternal AiPri. Himari and Mitsuki throw themselves into it with plenty of fighting spirit. Yet Princess Ring seems to be hiding a big secret, and as their circle of friends grows, so do the mysteries surrounding the ring. This second season of Himitsu no AiPri is a music and slice of life series.
