Colette the Al-cum-ist

When a mysterious visitor sends master Priscilla off on a journey with no clear return date, apprentice alchemist Colette suddenly finds herself running the workshop alone. Left to manage everything herself, Colette starts taking on jobs and adventuring to help people — which sounds wholesome enough until you realize this is an adult fantasy OVA adapted from an erotic RPG by Acerola. The setup is genuinely charming in that classic fantasy RPG way: a young woman finding her footing, meeting adventurers, dealing with monsters, slowly growing into her own. But the show doesn't pretend to be anything other than what it is. The alchemy angle is a fun detail that carries through the fantasy worldbuilding rather than just being window dressing, and the character roster — including a well-known hero named Sylvia and a fellow adventurer, Lyle — gives it more texture than the average entry in this genre. If you've watched Kyonyuu Fantasy or Isekai Harem Monogatari and wanted something with a slightly more grounded RPG aesthetic, this fits that niche. Fans of Kuroinu who prefer a lighter, less dark tone will probably find Colette's world easier to sit with. It's a 4-episode OVA from studio Majin, so it's a short commitment. Just go in knowing what kind of show it is and you'll get exactly what you're looking for.
