I Was Just About to Slay a Dragon, and You Tell Me My Fiancée Is a Dragon Girl?

[Reincarnated in Another World] [Protagonist with Absorption Powers] [Dragon-Slaying Expedition] [Mysterious Worldbuilding]

More than ten years had passed since Norun reincarnated in another world. He had been born into nobility from the start, but as an illegitimate child. What's more, this was a closed-off world surrounded by dragons, whose strength overwhelmingly surpassed that of humans. There were barely any dragon slayers.

But he discovered that he wasn't ordinary. This world had beings called "angels," blessed by the gods and endowed with special combat abilities. From childhood, Norun had noticed that his wounds healed on their own and that his body kept growing stronger. He began trying to earn a noble title, prove his strength, and uncover the secrets of the world.

Only later did he discover that his ability was to devour the powers of others.

A giant spiny-backed lizard? Eat it, and unlock the ability to control vines.

A phantom dragon? Eat it, and unlock the ability to control illusions.

A tyrannosaur beast? Eat it, and unlock...

Many years later, when he had become the empire's sole emperor and was called the "Heavenly Venerable Sacred Emperor," he would look back on that distant afternoon when he met his dragon-girl fiancée.
