The animation opener was produced by one of the more prominent anime studios.
Animation studio Madhouse was hired by Atlus to create animated cut-scenes, including the spiffy opener, for the upcoming Etrian Odyssey: Millennium Girl. This comes via Famitsu, who also showcased some scenes from the game.
Meanwhile, Etrian Odyssey: Millennium Girl is a remake of the first Etrian Odyssey, which released on the DS not too long ago. Unlike the original, you can also play with an original cast of characters in the single-player mode along with being able to play the game with your own custom-made heroes. The game is essentially a dungeon crawler with turn based combat featuring five different cast members. Let’s not forge the collection of different classes one can choose from.
