Tōwa launched the The World’s Strongest Rearguard novel on the Shōsetsuka ni Narō website in April 2017. Kadokawa published the novel’s first volume, featuring illustrations by Kazabana, in November 2017.
In March 2018, Rikizo launched the manga adaptation on Kadokawa’s Comic Walker web manga site. Kadokawa published the first compiled book volume in September 2018. Yen Press also publishes the manga adaptation in English.
Yen Press licenses the manga and novel in English and describes it as follows:
Corporate slave Arihito Atobe’s death in a freak bus accident marks the beginning of his new life as a kind of adventurer called a Seeker. Reborn into a fantasy world, he settles into a previously unknown job class called “rearguard,” capable of providing his (all-female) party with critical attack, defense, and recovery support. And it comes with an added bonus: Simply being at the back of the party line increases his companions’ fondness for him! Freed from the shackles of corporate life, Arihito is eager to start fresh as a newly minted Seeker!
