Synopsis

An unnamed Japanese vending machine otaku is crushed to death by a falling vending machine. He then finds himself reincarnated in a fantasy world dungeon as a sentient vending machine. He can see and hear but is immobile, with his speech being limited to stock Japanese vending machine phrases, such as "Hello there" or "Too bad". As a vending machine, he discovers he can dispense any item he has bought in his previous life, and can convert such sales to points, thus sustaining his existence. He is also able to use excess coins to add additional features to his vending machine body, and is able to choose which items he stocks or the prices of the items. Furthermore, he is able to use some magical abilities, including shapeshifting, invisibility, telekinesis, and a defensive force field.

Stuck in the middle of the wilderness, he encounters Lammis, a young female hunter. Lammis has a skill known as the Blessing of Might, which makes her ridiculously strong, but is still a novice at managing her own strength. The two quickly become friends after he dispenses some food items to the hungry Lammis. Calling him "Boxxo", she starts carrying him around on her back, which allows Boxxo to move, with his weight allowing her to more easily control her strength. The series chronicle their adventures as they start exploring the world's dungeon, and the characters they meet on the way.

Background

In the afterword of the first volume, Hirukuma describes his envisioning and road to publishing Reborn as a Vending Machine. He at first helped out with his father's independent business, though after the death of his father from a high fall, he closed down the business and began pursuing his ambition as a writer. He described his father's death as giving him acrophobia, and recalled thinking "I don't know when I'm going to die like my father did. One question went through my mind: Have I done everything I've wanted to in life?" On a site for submitting novels called Shōsetsuka ni Narō, he submitted several works of fiction, including another isekai piece and a battle-themed novel set in the near future, but was initially unsuccessful.

He described Reborn as a Vending Machine as his final effort after four years of unsuccessfully getting his novels published. Hirukuma wrote that "[it was] one that was fantastical and original, and one that I wanted to write [...] This wasn't a novel where I adjusted for the readers' needs, or had to think long and hard about constructing a plot. Instead, I pursued my own style for it, and it garnered the most popularity of all my work".
