Kyofu is the guardian of fear, but is also one of the more dangerous of the seven. He is a boogeyman, who is able to manipulate one's darkest fears and nightmares and bring them to life, with Kyofu getting sadistic pleasure from this. He is able to hide in the shadows, create illusions, and shapeshift. Kyofu likes to add bpdy parts to their own body, forming a "collection". Kyofu shapeshifts much easier and more often than the others, leaning into the uncanny valley.
