Reborn as a Vending Machine, I Now Wander the Dungeon, Vol. 2 (light novel)

"A middle-aged man with only one passion in his life meets a fitting end in a traffic accident. That's where most stories would end, but instead, this is when his story begins when he's reborn as what he admired the most in life--a vending machine! But his new lease on life(?) happens in the worst place possible--what can a vending machine do in a monster-infested dungeon when he can't speak or even move on his own?"--
