Grimoire is an upcoming fully voiced Magical School Academy game featuring cute Anime characters and seiyuus from Japan. Read on if you're interested in participating in the upcoming CBT.
My Japanese translation might be wrong, but the beta is only available for Android users with a Gmail account. Just Pre-Register like you normally would and enter your old or new Ggmail address instead. If you're lucky, they will send you a beta invite in your e-mail account asking to join a group with link to the CBT game APK or store.
