Youki

Youki met his end in an accident before being reborn into another world, where he eventually rose to become an elite commander within the Demon King's army. During a mission to intercept a hero's party, he fell instantly in love with the group's monk, Cecilia, even confessing his feelings openly on the spot — a moment that led him to abandon the Demon King's army entirely. Concealing his true identity, he entered the human world and quietly aided those around him, all in pursuit of the one who had captured his heart. His story is one of a supremely powerful demon who, when it comes to romance, is utterly clumsy and endearingly pure.
