Takahiro Kafū operates the Rabbit House cafe, transforming it into a bar at night where he works as the bartender, typically dressed in his uniform. He is the father of Chino Kafū, the husband of the late Saki Kafū—who designed Rabbit House's work uniforms and attended high school with Cocoa Hoto's mother—and the son of the individual inhabiting the rabbit mascot Tippy's body.

Physically, Takahiro possesses fair-tan skin, small grey eyes, and short, dull brown-grey hair, usually maintaining a very light layer of facial hair above his lip and around his chin.

He shares a likely military history and ongoing rivalry with Rize Tedeza's father, evidenced by challenges like, "Fine. But if I win, you pay five times the price. [...] This takes me back to that deserted battlefield. Just like back then, the winner will be me." Takahiro is exceptionally skilled with blow darts.

His role centers on supporting the main cast, overseeing the younger employees—Cocoa Hoto, Rize Tedeza, Chiya Ujimatsu, Syaro Kirima, Maya Jōga, and Megumi Natsu—during their shifts. He is acquainted with Midori Aoyama, a regular at the bar who writes there.
