Itʼs the first day of Planet Camp, and Aries Spring couldnʼt be more excited! She, along with eight other strangers, leave for Planet McPa for a weeklong excursion. Soon after they arrive, however, a mysterious orb appears and transports them into the depths of space, where they find an empty floating spaceship…
Shinohara (Sket Dance) launched the manga in May 2016 on Shueisha's Shonen Jump+ app. The manga launched simultaneously with its own voice drama, featuring Yūsuke Kobayashi as Kanata Hoshijima, Ayaka Suwa as Aries Spring, Lynn as Quitterie Raffaëlli, Aimi Tanaka as Funicia Raffaëlli, Daiki Hamano as Zack Walker, Ayumu Murase as Luca Esposito, Souichirou Hoshi as Charles Lacroix, and Kyousuke Kitayama as Ulgar Zweig.
The manga ended in December 2017, and Shueisha published five compiled book volumes for the manga. Viz Media began publishing the chapters online for free in August 2016, and published the fifth and final volume in print last December. The 2019 edition of Takarajimasha's Kono Manga ga Sugoi! (This Manga Is Amazing!) guidebook ranked the manga at #3, and the manga won the 12th Manga Taisho awards earlier this year.
