Venus Mission: I Was an Assassin-for-Hire Who Died, Now I'm Hunting Heroes in Another World (Light Novel) Vol. 2

AN ALLIANCE WITH THE DWARVES?

Awarded S-Rank for their heroics, Rei and Lydina are sent a special appraiser to make it official. Meet Eve—a sharp-eyed, blue-haired girl who wears an eye patch. She instantly identifies Rei’s apostle status and signs up for the cause with religious fervor. The new trio travel to the dwarven kingdom of Melgid, only to cross paths with heroes on a mission of their own.
A simple confrontation spirals into kingdom-wide conflict. Rei’s got the dwarves, magi-cannons, and golem troops on his side, but will that be enough to protect Melgid?
