Munster Academy is a GxB monster-themed visual novel made with Ren'Py in a week for the Monster Mash 2014.

Lyra (name changeable) is a normal teenager studying in a normal school, with a normal family and a generally normal life. One day she finds out that she's actually adopted, and that she's not human after all. In this world and time, Monsters may be pretty common, but they're still Monsters, so Lyra gets shipped off to Munster Academy, a renowned Monster school in their area. There she meets a fellow werewolf, Maiko, and a pompous bratty vampire, Bryce. Join Lyra as she gets used to her life in a new school, with new friends, and a new set of challenges for her to overcome.
