Living in another world as an Oni!

Synopsis:

Rin thought her biggest struggle was camping for three days to snag a limited-edition novel. She didn’t expect her reading binge to be cut short by Car-kun. And to add insult to injury? Truck-kun let Car-kun have this one.

Now dead, bookless, and bitter, Rin finds herself whisked away by a snarky, glowing "recruiter" into a new world. Armed with the mysterious Gluttony System, she discovers she can grow stronger by eating… well, everything. From magic beasts to cursed fruit, Rin’s appetite becomes her ultimate weapon—unfortunately, it also makes her always hungry.

Her goal? Survive, evolve, and maybe, just maybe, find a way to get back to that book she never got to read. But as her hunger grows and she inches closer to becoming an oni, one thing becomes clear:

Death by Car-kun was the least of her worries.
