What is The World’s Strongest Rearguard about?
Tōwa began serialising the story on the Shōsetsuka ni Narō platform in April 2017. Kadokawa later published the first light novel volume in November 2017, with illustrations by Huuka Kazabana. The ninth volume shipped on 10 September.
The manga adaptation by Rikizo launched on Kadokawa’s Comic Walker in March 2018. Its first compiled volume was released in September 2018, while the 10th volume shipped on 23 January. Yen Press also publishes the manga in English.
Yen Press, which publishes the light novels in English, describes the story as such:
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!
