Reincarnated as a noble thanks to a goddess!

It should have gone smoothly, but the skill I received—[Toxin Decomposition EX]—was too unremarkable, leading to days of being ridiculed at home...

However, one day he discovers that he can absorb monster abilities by eating their magic stones with that skill,

and is informed that he is the prince of a neighboring country!

What awaited him at the royal castle was an environment where he could experiment and train with abundant magic stones, allowing him to unlock his ultimate powers—

Eventually, he even acquires the abilities of the legendary monster Dullahan!

Surrounded by an assertive fiancée and a clumsy female knight,

the boy's new life to become "King" begins!!

While the early chapters are told from the protagonist's perspective, it shifts to a third-person narrative partway through.

We apologize for this change, but the third-person perspective will be the primary narrative style going forward.

※What is referred to as the "original work" is the published novel version.

As this is the web version, its content differs entirely from the published novel.

Furthermore, as the comic adaptation adheres to the published novel, its content also completely differs from this web version; please understand this as well.
