Ikaru♂

Ikaru is quick-tempered yet kind, and doesn't hesitate to act on his own perception of what is right. He is a Kannagi no Tori with the appearance of a young red-haired boy. Despite being a Kannagi no Tori, he has failed to retrieve the soul of a human because of his continued interference with the deaths of his targets. He is tasked by his superior to retrieve the soul of Ruu on his death date, or cease to exist on Kannagi Mountain.
