Hakuoro

Hakuowlo (ハクオロ) is the main character of Utawarerumono: Prelude to the Fallen. Once an amnesiac man found heavily injured in a forest, he was healed by Eruruu and led a rebellion before becoming the owlo of Tuskur. After a series of battles to defend his new country against external threats, he rediscovered the secrets of his own past, including his true identity as Uitsualnemetia's good half, before merging with the darker half and becoming the god united. Years after, Hakuowlo/Uitsualnemetia was sealed beneath Onkamiyamukai to prevent his other half from causing more havoc, a shrine was built around with Eruruu as its caretaker. He kept a watch over Tuskur and the world from within his domain. He then passed his mask and power over to Haku, becoming human in the process and leaving his domain/paradise.
