Meitantei Conan: Zero no Tea Time

Zero no Tea Time emerged from the expansive Detective Conan universe as a spin-off focused on the character Rei Furuya, also known as Tooru Amuro. Authorized by series creator Gosho Aoyama and illustrated by Takahiro Arai, the manga debuted in Weekly Shonen Sunday in 2018. It was developed to explore the daily life and triple-layered identity of the character, providing a softer, slice-of-life look at a figure usually shrouded in the intrigue and espionage plots of the main series.

The design of the series centers on Arai's refined art style, which maintains the core aesthetic of the franchise while pivoting toward a more relaxed, episodic narrative structure. By shifting the focus from criminal investigations to the mundane and often humorous aspects of the protagonist's routines, Arai successfully expanded the appeal of the character to a wider audience. The work was well received for its ability to balance character development with the established tone of the original series, leading to a successful anime adaptation.
