The official website for Shogakukan's Petit Comic magazine announced on Saturday that Maki Enjōji's SP x Baby manga series will end in the January issue on December 8. The series follows a part-time worker named Tamaki who is in the middle of searching for a full-time job so he can pay for his brilliant younger brother's tuition.

The series launched in the magazine's September issue in August 2014. The first compiled volume of the manga shipped on August 10 and ranked at #48 when it debuted on Oricon's weekly Japanese comic ranking.

Enjōji ended her Dear Brother! manga in April 2014. Viz Media licensed Enjōji's 10-volume Happy Marriage!? manga series in North America, and the company released the 10th volume in February.
