The first promotional video for The Invisible Man and His Soon-to-Be Wife has been released, offering a glimpse into Project No.9's adaptation of the urban fantasy romance. The trailer highlights the central dynamic between Yakou, a human detective, and Tounome, her invisible partner whose abilities prove surprisingly useful in their line of work. Despite Tounome's invisibility, the blind Yakou can sense his presence, hinting at the unique connection that will form the core of the series.

Adapted from the manga of the same name, the series explores the developing relationship between the two protagonists. The PV suggests a blend of detective work and gentle romance, aligning with its Iyashikei and Urban Fantasy tags. Project No.9, known for their work on series like Bottom-Tier Character Tomozaki and My Senpai Is Annoying, will handle the animation.

The trailer also sets a soft, character-focused tone, emphasizing the developing attraction between Yakou and Tounome. With a MAL score of 7.62 from over 13,000 voters, the source material has already garnered interest, and this adaptation is poised to bring its unique premise to viewers when it premieres in Winter 2026.
