Lost Wings, Forgotten Deity

Monsters have suddenly appeared on Earth, destroying the lives of many people and living things; causing havoc and grief. Luckily, 5 people known as 'deities' appeared as well. Every generation, 5 special individuals are given this unique and unnatural gift to control a specific element (Air, Fire, Water, Earth and Ice). And it's up to HuProAM (Human Protection Against Monsters) to gather these five deities. Unfortunately, after the 3rd generation, only 4 deities remained up until the present. The last position had remained forgotten to some but still open for whoever will be given the power to control one of the elements. But just as then, rumors started spreading that this so called 'forgotten deity' has returned. Is it true? If so..who is it? How will the present generation deities react?
