Jidou Hanbaiki ni Umarekawatta Ore wa Meikyuu wo Samayou 3rd Season

An entire year has passed since Boxxo arrived at the village of Clearflow Lake. Alongside Lammis and his other friends, Boxxo has been able to create a steady customer base and even halt the Netherlord's evil plans to invade the different strata within the dungeon. However, some of the former members of Menagerie of Fools, who have joined the Netherlord's side, are still at large. Determined to protect everyone's safety and maintain the status quo of Clearflow Lake, Boxxo sets out to find the fugitives and put an end to the Netherlord's oppression—using the various vending machine forms at his disposal.
