Chillin' in My 30s After Getting Fired From the Demon King's Army

Dariel is fired from his position as a dark soldier in the Demon King’s army and finds himself at a complete loss. In the forest, he happens to rescue a girl named Malika, who takes him to a human village called Lux where his hectic second life begins.

Dariel's first quests as an adventurer go smoothly, but the village's other adventurer, Gashita, continues to see him as the enemy. Word that a high level monster has appeared near the village arrives. Dariel heads into the forest to bring Gashita back.

Dariel learns that Lux Village once flourished due to a nearby mine. When the demons took it, they condemned the village to a slow death. As the mine is Dariel’s old workplace, he decides to visit it to see if there’s anything he can do for his new home.

Bashbarza is in a rage after being reprimanded by the Demon King for losing the mythril mine. Meanwhile, in Lux Village, the mood is a celebratory one. Dariel runs into an old coworker and sees an opportunity to prevent conflict between humans and demons.

Lux Village is starting to thrive, thanks to the Mythril Mine, but Fittbitan has taken control of the forge. The arrival of a legendary swordsmith makes Fittbitan view Dariel with even more hostility, and so the adventurer challenges Dariel to a duel.

Dariel is shocked at the identity of his unexpected sauna companion. How will this affect their future? Dariel stands at a crossroads in his life and Lux Village begins to change. Then, one day, Dariel hears that the Hero’s party is visiting the village.
