A Saving Menace on this Wonderful world (WTDSxKonosuba) (Hiatus)

Proluge

I had this idea for a while now so I wrote it now. As mentioned this story will have only Iruma from the WTDS universe. Iris will be 16 for convenience. To understand you need to have read Konosuba atleast until volume 16.

This is just after Kazuma left the services of Wiz and Vanir (when he kept decreasing and increasing his level).

"I know Kazuma-san's luck is very high but his chances for survival are quite slim" said a worried Wiz.

" Moi thinks so too... say do you want to help the brat kid?" Vanir said.

"I do but we can't defeat that big an army all on our own" said Wiz still racking her brains for a solution.

"Who said anything about us fighting alone" said a smirking Vanir.

"Vanir-san I know you well enough by now so I can easily tell you are plotting something" said Wiz.

"Shop owner who gives nothing but red digits you are indeed correct this time. Through Moi power of clairvoyance, a very interesting future is possible if we call in ........." Vanir said whispering the last words into Wiz's ear.

"W-What?! You can't be serious! It's him we are talking about!" Wiz said frantically.

"Ah yes! I see it, the look on that goddess's face and the reaction of the brat boy. Moi can't wait to taste their negative emotions" Vanir said while laughing hysterically.

Wiz sighed knowing there was no way to stop the devil now.

"Vanir-san you truly live up to the name of the duke of hell don't you?"  she questioned him.

"But of course shop owner who brought coolers in the winter season" Vanir replied in a matter-of-fact tone.

"........Could you please stop using your powers" Wiz said almost on the verge of crying.

"All jokings aside let's just call him already" Vanir said.

"How can you talk without showing respect to him?" said Wiz a bit curious.

"He is what you may call a friend of mine" Vanir replied nonchalantly.

"Yeah it does make sense to me now you being the strongest duke of hell and him being the Demon king" Wiz said the last part a bit low.

"Oh......"

"Something wrong Vanir-san?" Wiz asked concerned.

"It's nothing" He waved her off, "It's just that he has arrived" Vanir replied

"Oh...Wait-Wait Wh-" Wiz couldn't finish as the whole area was filled with falling dark feathers.

In front of them was a very young man who didn't look any more than 19. Behind him was a cape fluttering giving his overall outfit a very regal look while his blue hair with purple streaks covered the ends of his ears.

Wiz could do nothing but blush seeing the handsome yet beautiful man in front of her.

"Shop owner who is thinking about the handsome man let me introduce you, This is Iruma-sama ruler of the netherworld and king of all demons"

Iruma gave a charming smile while taking his hand out for a greeting "As Vanir-san already said I am Iruma the demon king from netherworld"

"O-Oh I am Wiz the lich I own this magic store" said a fumbling Wiz.

"This place looks great maybe I will buy a souvenir for grandpa while I am here" Iruma said looking around in amazement.

"Yeah so Vanir-san what was the favor you wanted from me?" Iruma asked a bit seriously

"About that........................" Vanir told the young demon king his role.

"Sure I am on board" Iruma replied

"Really?" Vanir asked surprised by the instant answer

"You are the strongest of the archduke's in hell, and above all my friend so of course I will help. Moreover, it is against my motto to not help people in need and this also solves a problem of mine" Iruma replied clearing any skepticism Vanir had.

"Strange" Wiz accidentally said out loud.

"Hm" Iruma tilted his head

"No, It's just that you are the least demon-like demon I have ever seen" Wiz added

"Hahaha shop owner you will get your answer from the fight that is going to happen" Vanir said laughing all the while.

"Eh?" Wiz stood there not understanding anything to which Iruma just nervously laughed.
