I Offer Despair to the Villain

From running a quiet café to becoming the ultimate puppet master across dimensions—Mizukawa Yuki's rise begins with a mysterious cat and a door to infinite worlds. Her deal? Fulfill wishes, but leave the villains something special. At first, they laugh: "Who's this nobody?" Then they beg: "Stay away!" With each cat she brings along, Yuki gains new powers, turning her into the most unpredictable force any world has ever seen. She may not be the strongest, but she's definitely the most troublesome.
