Reborn as a Vending Machine, I Now Wander the Dungeon (Japanese: 自動販売機に生まれ変わった俺は迷宮を彷徨う, Hepburn: Jidōhanbaiki ni Umarekawatta Ore wa Meikyū o Samayō, lit.

Reborn as a Vending Machine has been well received by critics, with particular praise being directed at the novels' unique take on the isekai genre.

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".

[3] 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.

[3] In the afterword of the first volume, Hirukuma describes his envisioning and road to publishing Reborn as a Vending Machine.

[5] He described Reborn as a Vending Machine as his final effort after four years of unsuccessfully getting his novels published.

[5] 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.

Theron Martin of Anime News Network reviewed the first volume positively, praising its unique take on the isekai genre, Hirukuma's writing style, and the relationship between Boxxo and Lammis, which he found to be impressive and not having to "resort to hackneyed gimmicks".

[3] Similarly, Robert Frazer of UK Anime Network found Reborn as a Vending Machine to be "a blast of fresh air to flush out the stale isekai genre", as "it’s fun and different to defeat the villain with Diet Coke and Mentos instead of just firing a Saiyan blast at a higher powerlevel".

[39] Rebecca Silverman and Lynzee Loveridge, in Anime News Network's Spring 2018 Light Novel Guide, also praised the setting but found the writing to "read like fan-fiction-level quality".
