The creator known as Inu is a Japanese manga artist whose work spans both original serialized publications and adult-oriented material. The artist operates under the pen name Inu, which is written with the single Japanese character for dog, and has also been credited under the real name Oouchi Takamichi. Born on November 8, Inu has been active as a prolific artist contributing to various manga magazines, including publications such as Comic Megastore and Comic LO, and has also worked within the doujinshi, or self-published, circle Hohhe!! Dan.

Inu is best known for the manga series Hatsu Inu, a story arc that was collected into a tankoubon volume beginning in 2006. The series proved popular enough to span three volumes released between 2006 and 2008, and it was later republished as a two-volume complete edition in 2010. The popularity of this work led to its adaptation into anime. Pink Pineapple produced Hatsu Inu: The Animation and its sequel, Hatsu Inu 2: The Animation, which were released in 2007 and 2008 respectively. Another significant work by the creator is the manga Furueru Kuchibiru, which was adapted into the anime series Fuzzy Lips. For this production, Studio 1st handled the animation, and Inu was credited for the original manga and original character design.

Inu’s artistic identity is closely tied to the genres of comedy, romance, and school life, frequently with an adult or ecchi emphasis. Many of the artist’s published works fall under these categories, and the creator has maintained a consistent presence in the market for mature-themed manga and anime. The creator's significance within the industry is marked by the adaptation of multiple works into anime, a notable achievement within the field of adult-oriented original animation. An interview conducted in 2009 highlighted the international recognition of the Hatsu Inu series, noting the iconic status of its character Shion Fujimo within the hentai anime community.
