Mirror: Enchanting Reflections is a DLC of Mirror, which is a game that combines match-3, galgame elements and beauties developed by Kagami Works. If you want to learn more about those beauties, you need to beat them first. How the story goes is choice-based so your choices will ultimately decide their fate.
This DLC contains 48 CGs that were never shown in the game. 4 more CGs for each girl and combined with the CGs in-game will draw you an enchanting picture you’ve never experienced before. If you get stuck in the game, check out the video walkthrough and gameplay for the game.
