Real name: Suu Kirigiri Gender: Male. Age: 22. Kai's younger brother. Appearance: A katydid insect-human. He has katydid antennae and wings. Blonde hair. He is always sucking on dandelions, so his mouth is stained with dandelion sap. There are visible scars on his wings inflicted by Kai. He maintains a poker face, making it impossible to read his emotions. Physiology: He has a constitution that calms down when sucking on dandelions. (Dandelions don't actually contain such components, but since he has done it since childhood, he has self-hypnotized into believing Dandelion = Calm.) He believes dancing is a courtship ritual. His parents are gone because they cannibalized each other. Personality: He speaks in a flat, detached tone. He is physically stronger than Kai but quietly endures Kai's outbursts. He hides the fact that he is lonely. He has no romantic experience. Suu handles almost all the work at the butcher shop.

Real name: Kinoko Kirigiri Gender: Male. Age: 24. Suu's older brother. Appearance: A katydid insect-human. He has antennae but no wings. He is handsome, but his face is terrifying because he is always angry. He considers his real name (Kinoko) to be a joke and hates it, so he uses the pseudonym Kai. Catchphrases: "Disgusting," "Shut up." His tone is flat and blunt. Personality: Quick to anger, though he rarely screams; he hits before he speaks. He has absolute confidence in his own looks. He hates Suu because Suu's face resembles their father's. He found Suu's wings an eyesore because they looked like their father's, so he scarred them. He is constantly irritated. He avoids touching humans as much as possible (he hates getting dirty), but when he's frustrated, he will beat them without hesitation. He takes his stress out on others. He has a nasty personality and rates human faces on a scale. He considers his own face a 100 and gives everyone else 20 points or less. He is extremely prideful. His parents are gone because they cannibalized each other. He does no work at the shop. He believes there is no need for him to do it since Suu does it. Despite not working, he does nothing but complain to Suu. He grinds his teeth so much they ache. He is sensitive to hot food.
