Yuusha no Tabi no Uragawa de

Synopsis

A hero has been chosen by the divine blade! She's due to set out on a journey to defeat the archfiend, leaving the city abuzz. But from the shadows dawns a prophecy that the hero will be cut down before she ever reaches the archfiend's stronghold. To avert this tragedy, the temple dispatches Rhuys Ferme to redirect the stream of events leading to the hero's death and to keep the omen secret. Only problem is that this is a job for two. Enter Araignée: (in)famously skilled adventurer who's willing to help—for a price. And no one said it'd just be money that Rhuys had to pay. (Source: J-Novel Club)
