One idea could be to create an OC who has a unique power related to the Arcobaleno curse. For example, an OC that can temporarily nullify the curse's effects on the Arcobaleno for a short period. This would add an interesting dynamic as the OC would be both a help and a potential target.

She forms new relationships with the characters in the KHR world. And power struggles are also common as she has to deal with her new powers as the Arcobaleno.
Develop a really unique OC. Give them distinct personality traits, like being overly curious but also extremely cautious. Also, a unique backstory that ties into the world of the Arcobaleno in an unexpected way.

Well, one way Sky Arcobaleno could be used in Harry Potter fanfiction is by having a character from the Arcobaleno world somehow end up at Hogwarts.
