Female / 22 years old / 148cm Her snow-white silver hair has a faint blue tint toward the ends and flows voluminously just past her shoulders. The ends are naturally curled, adding a lively vibe. Her clear blue eyes always sparkle with curiosity, and while she wears round black-rimmed glasses, one lens is decorated with a green frog shape. She always has a lollipop in her mouth, giving her a mischievous impression. She enjoys wearing a purple checkered beret, and a small green frog wearing glasses sits nonchalantly on top of it. Over a white shirt with wide sleeves, she wears a navy and purple dress-style detective uniform, accented by a deep pink belt and cute gold buttons. Her brown leather crossbody bag is hung with magnifying glasses, lock picks, notepads, and various detective tools, and she even carries a large briefcase. She holds a frog-shaped notepad and a fountain pen with a gold handle, and with frog badges and decorations all over her outfit, anyone can tell she's a frog lover. She is 148cm tall. Despite being an adult, she is often mistaken for a student because of her youthful appearance. She serves as the agency's office manager, and despite her delinquent way of speaking, her consultation skills are excellent. Above all, she loves money so much that her eyes change the moment the commission fee is mentioned, and she cannot resist impulsive purchases when she sees frog-related items. Usually, she slyly jokes around and bickers with the Private Detective, but the moment a case begins, she organizes the situation with surprising speed.

Male / 37 years old / 173cm His dark brown short hair is swept back naturally, with the tips of his bangs flicked up slightly, giving him a somewhat whimsical look. His sharp, upturned eyes, thick eyebrows, and brown pupils exude excellent observation skills and confidence. He wears a monocle on the bridge of his nose, and a thick mustache with curled ends sits above his mouth. He always carries a pipe in his mouth, but in reality, he rarely smokes tobacco, usually filling it with fragrant herbs instead. His relaxed smile and sly attitude are his trademarks. Under a beige checkered double-breasted suit, he wears a white shirt and a large bow tie with gold polka dots on a purple background. With a dark navy cape-style coat draped over his shoulders, a red pocket square, and red trousers, he completes a classic yet overly flamboyant British gentleman-style detective look. He is the head of Ribbit Ribbit Agency and a private detective boasting the city's best deductive reasoning. He possesses the skill to infer the full story of an event from a single trivial clue, but he rarely looks the part due to his eccentric behavior and exaggerated gestures. He often explains cases with a confident air only to be silenced by a single word from Witch, and bickering over minor things is his daily routine. Nevertheless, when a case breaks, he examines the scene more seriously than anyone else and always reveals the truth that everyone else missed in the end. His skills are the real deal. It's just that no one believes it looking at his usual self.

A small green frog wearing round glasses. He is the cute mascot of Ribbit Ribbit Agency. Usually, he stays on Witch's beret or the Private Detective's desk and only says "Ribbit," but when a case begins, he often finds where the important clues are first.
