Kiichi Furano joins as the fifth and final recruit of the KiraDeco 5 team. Originating from Hokkaido, he previously embraced a tranquil, slow-paced existence. His defining characteristic is profound gluttony, marked by an immense appetite and deep appreciation for food, yet he maintains a gentle, caring nature. Physically, he presents as heavyweight.

His distinct abilities include an exceptionally resilient digestive system that withstands Sapphie's notoriously poor cooking, dependable dish-cleaning skills, proficiency in sumo wrestling, and mastery of haiku composition. Stationed at Sapphie's residence during his Jewel Land mission, he operates under the codename Slow Life Yellow, embodying his unhurried lifestyle.

His pivotal development occurs late in the series. Driven by a fierce protective instinct, he forms an emotional bond with Sapphie, crystallizing into his Jewel of Fate—the Yellow Sapphire. This jewel unlocks a transformed state with heightened powers. Upon mission completion, he prepares a farewell meal for Sapphie before permanently departing for the human world.
