Shunsuke Sarai is the credited author of the light novel series and original creator behind the multimedia franchise known as Dog & Scissors, also titled Inu to Hasami wa Tsukaiyō. This name represents a collaborative writing duo consisting of two individuals, one who graduated from an engineering department and the other who graduated from a literature department, both from a university in Chiba Prefecture. The pair formed several years after graduation when the engineering graduate proposed they pursue careers as novelists together.

The series Dog & Scissors serves as their debut work and the foundation of their public creative identity. The light novels began publication on February 28, 2011, through Enterbrain under their Famitsu Bunko imprint, with illustrations provided by Tetsuhiro Nabeshima. The series concluded on January 30, 2015, comprising fourteen volumes in total, which includes ten main story volumes and four short story collections. The work earned the 12th Entame Awards Grand Prize in the novel category.

From this original source material, an adaptation history developed across multiple media. A manga adaptation illustrated by Kamon Ōniwa was serialized in Kadokawa Shoten’s Shōnen Ace magazine from May 2012 to March 2014, later compiled into four tankōbon volumes. A twelve-episode anime television adaptation produced by the studio Gonzo aired from July 1 to September 16, 2013, directed by Yukio Takahashi with series composition by Toshizo Nemoto.

The creative identity of Shunsuke Sarai reflects the combined backgrounds of its two members, blending perspectives from both technical and literary disciplines. Their stated mutual interests include reading books and exploring bookstores, a shared enthusiasm they note has earned them a poor reputation among traveling companions due to their tendency to seek out bookshops even while on vacation. This thematic preoccupation with books, reading, and the relationship between authors and their audience is central to Dog & Scissors, which follows a book-loving protagonist who is reincarnated as a dog and becomes the pet of his favorite novelist.

Beyond their signature work, the creative partnership has contributed to other projects. The duo is credited with script work for the video game Star Ocean 6: The Divine Force, demonstrating their continued activity within the entertainment industry.
