(Merlin was in her workshop and Y/N was sitting in the corner in a chair. His father was on a mission with the other sins and Merlin needed to stay back to work on a project she was working on.)

Y/N: Hey Auntie, what are you working on?

Merlin: Well, I guess you could call it a weapon to help up defeat our enemies.

Y/N: So, it's like a powerful weapon designed to kill demons.

Merlin: Exactly, smart as ever I see~

Y/N: (Rubs back of his head while blushing)

Merlin: (Chuckles, but soon notices that that the amulet was starting to form.) Gasp! It's working. (She soon levitates all the pieces and they all came together and formed the Demon-Hunter amulet.) It worked!

Y/N: (Walks up) Good job, Auntie! So, who are you going to pick to use it?

Merlin: That's the thing about this amulet, it chooses who it deems worthy. (Lifts the amulet) Find the one is worthy and can slay the demon king! (The amulet flies out of her hands and than out the window searching for who is worthy.)

Y/N: (Thoughts) I wonder who it will pick.

Timeskip: (The kingdom was under attack from a shadow demon that was summoned by a reckless person. It was laying waste to the land and sins were still on a mission. Merlin tried to kill, but it soon overwhelmed her. Now, she was laying on the ground unconscious. The Shadow Demon looked at her while licking her lips.)

(Y/N saw that it was going to kill Merlin and he ran in between the two. He looked at the thing with no fear in his eyes.)

Y/N: You're not going anywhere near her!

Merlin: (Weakily) Y/N, run.

Y/N: No! I won't let you die, (Back to the demon) If you want her you have to go through me!!! 

(The Demon charged at Y/N with the intent to kill and Y/N ran for it with no hesitation. As soon as the demon was going to claw Y/N's head off a red light and hit the demon which made it crash into a house. Y/N opened his eyes and saw that it was the Demon Hunter Amulet!!)

Y/N: The amulet! (Grabs it)

Merlin: (thoughts) It chose Y/N!? (Chuckled) Why am I not surprised~

Y/N: (The amulet switched turns and it says the words in english) For the Death of he Demon King, Eclipse is mine to Command?

Y/N: Incredible! I can feel my demonic energy surging through out the armour.

Shadow Demon: RAHHH!!!!

Y/N: (Looking at the demon) Alright, let's end this. (Holds hand out which makes eclipse appear)

(The Demon tries once again to kill Y/N, but the latter leaps forward and begins to slash it's body damaging it more and more.)

(Finally he leaps in the air and finishes it off with a-)

Y/N: Enchanted Hell Blaze!!!

(The move disintegrates the whole monster and once it disappears Y/N, helmets vanishes and looks at what he has done with a smile on his face.)

Y/N: Hell yeah!! Gasp! Auntie! (Runs to Merlin and helps her up) You okay?

Merlin: Yes, thanks to you Demon-Hunter. I should've known that the amulet was going to pick you. Use it wisely.

Y/N: I won't let you down! (Smiles as they walk to the king to inform him of the death of the demon.)

Hope you enjoyed the chapter!!!
