Yuuto is a shy and timid boy coming from a linage of powerful demon
slayers. Being a pacifist of nature, he is unwilling to bring harm to
anyone crossing his path, be it demon or human. He is allergic to cats,
often leading to violent sneeze attacks whenever his cat-demon
companion Himari is near. Full of good intentions, he gives everyone a
chance, even if it means putting himself and those around him at risk.
