The World’s Strongest Rearguard was originally a Shosetsuka ni Naro web novel by Towa, which began in 2017. A light novel series Illustrated by Huka Kazabana and published under the Kadokawa Books label followed the same year, and has nine volumes as of September 2025. Yen Press describes the light novel series’ synopsis 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.
The World’s Strongest Rearguard also has a manga by Rikizo.
