Papa no Iu Koto wo Kikinasai! - Usagi no Mark

Papa no Iu Koto wo Kikinasai! - Usagi no Mark is a light novel volume authored by Tomohiro Matsu, serving as a spin-off to the main Papa no Iu Koto wo Kikinasai! series. Published by Shueisha under their Super Dash Bunko imprint, the volume focuses on Hina Takanashi, one of the younger nieces from the primary narrative. It was crafted to expand the character's internal development and provide readers with a deeper look into the domestic dynamics of the family unit, reflecting the series' thematic emphasis on unconventional parenting and personal growth.

The character illustrations for the series were handled by Yuka Nakajima, whose soft, expressive aesthetic became a defining visual element for the franchise. The designs were intended to capture the vulnerability and charm of the children in the story, balancing lighthearted moments with the more somber emotional beats inherent to Matsu’s writing style. The series as a whole was generally well-received by fans of the genre, contributing to a broader multimedia presence that included anime and manga adaptations.
