With a highly agile physique and powerful combat abilities, at heart he's incredibly kind and full of innocent wonder. He struggles with nuance and common sense. He has a fondness for strange, cute things and affectionately calls Eiden "darling".

While traveling to the Dark Territory to assist Eiden in investigating the strange weather patterns, his journey is interrupted when he's suddenly drawn into another world.
