“Your majesty demon lord, please sign a document here. But please be careful not to put your hand at the wrong place.”

“Your majesty Ya Lin, human army are invading us but I will protect you with my life!”

O God, what is this? I just wish to be an ordinary person with carefree life and stuffed with food till death. Why I am the one who will become the future husband of the demon princess, the future demon lord? And also completing a near impossible task ——-resurrecting my mother-in-law? Luckily becoming a demon does have its own benefits, granting each demon ability to cultivate skills.

However, what type of circumstances are this, mission going to other worlds and conquer them?

I have a senior sister who taught me boxing, her name is Mai Shiranui!

I have a teacher who teaches me swordsmanship, her name is - Denise!

Hello everyone, I'm Surtur, a professional toolman for five years... or even many. My contracting services include, but are not limited to, spreading the flames, destroying worlds, rescuing damsels in distress, playing cards with Slaanesh, slacking off, shipbuilding, driving, card-drawing, human-reason repairs, and so on. If needed, please post a notice in any tavern in Terra (the more shabby Terra) frequented by bounty hunters. Of course, I personally recommend contacting them through dreams. Our shop is short on staff, and I'm too busy on Terra to be an account manager. What? You want me to prove my skills? Come on, Levantine. Show this guy a Ragnarok! Tell him why I dare to take on such a delicate task! No reason. Simply because I'm Surtur!

The good news is that this thing can eat anything!

Whether it's animals, plants, or various elements, you can extract energy from anything you eat, and it can even strengthen your body and evolve your life level.

The bad news is that this thing replenishes what you eat...

Are the Sharingan and Byakugan strong? You'll grow as many as you eat!

Are tailed beast chakra strong? Then you probably wouldn't mind having a few more tails, right?

Are Devil Fruits powerful? Would it be okay to have more markings on my body?
