"Star Buddy" - people call it that to praise a buddy who solves a big case. In the United States of America, where humans and beastmen coexist, the police have introduced a buddy system between beastmen and humans as a symbol of equality and peace. Meanwhile, Dyna, a cop on the brink of breaking up with a buddy, meets Demio, a 3-inch long-nosed beastman who was caught in a suspicious panty business. I never thought I would have to risk my life with someone like this...! The uneven duo will protect the peace of this country and rise to become "Star Buddy"! ? Slapstick buddy fantasy!
