Vali Lafey

"I'll be the next Overlord, and I won't let anyone get in my way...!"

The protagonist of the game. A descendant of the founder of Asgard—Overlord Loki. Despite being born in one of the most prestigious houses of the empire, the strong demonic blood he inherited gave him demonic features, earning him the ire of his family who were all Divine-leaning in terms of inherited blood. As such, he was eventually disowned by his own family. When civil unrest broke out as the result of the Chief God Odin's death, he gathered an army of his own for the sake of Divine-Demon Unification. He was gifted the Key of Yggdrasil by a youth sharing the same name as the former Overlord, Loki, and as a result was given the power to carve open a path towards his own destiny. Beginning with his sister-in-law Brunhilde, he turns the goddesses into his servant deities and walks the path of becoming the Overlord of a New Generation.
