Kazusa Yuu, a boy with rather unusual hobbies, was supposed to have died young... but before he knew it, he found himself in an unfamiliar forest.

Thrown into a world not only penniless but also without even the basic necessities of life, Yuu laughed, unable to hide his excitement. This was because he had found himself in an environment where his hobbies, once ridiculed as useless on Earth, could finally be put to good use.

Yuu's hobbies and special skills are "survival knowledge" and "an interest in unknown ingredients." To Yuu, this other world was a treasure trove of unknown ingredients and the first place where he truly felt affirmed.

Utilizing a simple cheat ability—gaining the power of any monster he ate, growing stronger with every bite—Yuu traversed one perilous monster-infested region after another, eventually devouring his way across the entire world.

"A-are you really going to eat that...?" "In this otherworld's monster-ridden lands, it's a valuable source of protein!"

Eat, grow stronger, and eat again! This is a story of consuming survival meals in a fantastical otherworld.
