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.

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.

The Hero, Laidy, has two objectives: to have new mythril weapons made, and to find a new ally to help defeat the Demon King. Laidy becomes aware of Dariels true abilities and asks him to join her party. Dariel declines, but Laidy refuses to accept it.

Dariel and the others rush to the Mythril Mine on a rescue mission, but the Magical Fire Beast, Salamandra appears in their path. Dariel presses ahead with their rescue efforts, but Bashbarza, who has obtained tremendous power, has other ideas.
