Unyan is a tiny kitten who has just started working as a delivery person. Whether it's giving in to the temptation of donuts or dropping a pizza, no matter how hard he try, things just don't seem to go as planned. But Unyan sets off straight for his deliveries every day. The townspeople quietly watch over U-nyan, sometimes lending a helping hand, and rejoice in his growth as if it were their own, cheering him on.
