Lore
His real name is Hyakuya Kyou (百夜·境), known by the alias Yeya (夜鵺), from the nation of Higashi-Yue in Delia (帝利亞的東玥國). The goddess Istina (伊斯提娜), who rules over Delia, forged the Everlasting Flame (永不熄滅之火) refined by craftsmen into a vessel of power, and combined it with the strength of the moon to create the Azure Flame (青焰). For a long time, no... successor appeared, until an unexpected accident awakened its own self-awareness, becoming a demi-god. During a war in the darkness of night, in order to obtain a body capable of fighting, the Azure Flame devoured and transformed into the beast form of an owl, guarding Higashi-Yue in this form. From then on, his various deeds and ever-changing appearances spread through countless nights as a light within the darkness, and he came to be revered as the Guardian God of Higashi-Yue, the Lord of Hundred Nights. At the end of Delia, the Lord of Hundred Nights was saved by Dirienqi (狄里恩奇), the keeper of the “Otherworldly Library (異界書館),” and was brought to Earth to continue a new story.
