Heylel

Heylel (ヒーリール, Hiiriiru) is a demon leading the semi-organized Sheol. Originally a figure of little importance and power, he'd be encouraged to seek his fortunes elsewhere, self-preservation paramount as he hoped to avoid their quarrels. Thus, learning of Earthland and a way to get there proved a valuable opportunity. He was among the first to settle in Sheol, acclimating to Earthland's climate faster than his contemporaries. Through this, he would realize his greater affinity for Earthland's ethernano; with it came power. While initially founding Sheol to validate his own existence, he has come to care for the inhabitants as if they were his own kin, driving him to make their home the best it can be. Even if it comes at the cost of others.
