In 'Whose Item Is This?', players step into the shoes of Sam, a quirky and somewhat unreliable private detective known for losing things rather than finding them. Set in a bustling city full of eccentric characters, Sam is tasked with identifying the rightful owners of bizarre and random items that mysteriously appear in their cluttered office daily. Players must interact with the zany cast, gather clues, and participate in hilariously odd mini-games that reveal the backstories of the items and their owners. The more items they return, the closer they get to solving a grander mystery lurking above the city's chaotic underbelly.
