Reborn as a Vending Machine, I Now Wander the Dungeon, Vol. 3 (light novel) - Hirukuma - Bog

I actually beat the lord of the Labyrinth stratum! This vending machine's not doing too bad for himself, huh? However, an increase in notoriety means an increase in requests. To name a few, we've got mapmaking, monster hunting, and...getting loaned out to the winner of an eating contest?!"Boxxo is all mine for the whole day!"...I guess I've got a date with Shui and her bottomless pit of a stomach. I'm up to the challenge, though. I just hope her boundless gluttony doesn't exhaust all the food (and points) I have!
