3rd person pov

Y/N had been laying in bed, staring at the ceiling with a bored expression. No matter what he couldn't fall asleep, however a magic portal suddenly appeared in his room.

Looking over he saw Rias who grabbed his arm and pulled him off his bed and over to the portal. His eyes widened as they were suddenly transported somewhere.

Rias: I'm sorry Y/N, but we need the real you

She placed a hand on his chest before his hesd throbbed, Fenrir had been brought back by Loki and they were struggling to hold him off.

He fell to one knee, panting a bit as his memories came flooding back to him. Getting up he looked to her as she held a guilty expression.

Suddenly something crashed into the ground as they all looked over, a hammer implanted into the ground as he sighed.

Y/N: After this, no more

He began walking over as Rias sensed the change in his magic, now emitting a holy power. Bringing out his arrow he pierced his chest, Requiem appearing once again.

Loki: Oh, you're approaching me? Instead of running away you're coming closer?

Y/N: I can't beat the shit out of you without getting closer

Loki: Then come as close as you like

He quickly changed direction, approaching the hammer as Loki watched him with a smirk. Grabbing it he tried to pull it but it wouldn't budge.

Gritting his teeth he used his other arm, pulling harder as it moved slightly. Requiem grabbed on too before a dark wave came from him.

A moment later Y/N picked up the hammer, holding it up with his left arm. Loki looked to him in shock before Y/N started levitating off the ground.

Loki: How!? You're just a human!

Gold Experience Requiem: Reality is on our side, i returned it to a point where you didn't have to be worthy to wield it

Y/N: You disturbed my peace, so it's only fair that i get to do this

Fenrir lept at Y/N, going to clamp his teeth down on him before he was smashed across the face by Mjölnir.

He crashed into the ground before Y/N went towards Loki, he tried blasting him with a barrage of magic but Requiem used it's ability.

The magic began retreating back to Loki as Y/N got closer, his eyes widening upon witnessing Requiem's ability.

He went to escape but Y/N tossed Mjölnir, hitting him in the back before it went back to normal. Loki was forced into the ground as he couldn't move the hammer.

Y/N floated down and went over to Loki who was stuck on the ground. He looked up to him and Requiem in fear but he felt the holy magic eminating from his arm.

Loki: W-What are you?

Y/N: I'm Y/N, the strongest human you'll ever see, and this... is Gold Experience Requiem

Loki was assaulted by a series of kicks from Requiem as he let out a crt, Mjölnir preventing him from escaping the attack.

Gold Experience Requiem: MUDA MUDA MUDA MUDA MUDA MUDA MUDA MUDA!

Timeskip

Y/N sat up from his bed, holding his head as he looked to his left arm. After it had been finished, his memories had been blocked off again.

But before that happened, he swapped out his sacred gear, no longer having Requiem or any he knew of, he didn't check to see what it was.

Getting out of bed he walked out his room, seeing Trish who was walking towards the living room so he joined her.

Y/N: Hmm... morning

Trish: You sleep well?

Y/N: I think, i woke up and felt like i had barely slept for some reason

Trish: Must be because you slept weird... has anything changed because of the arm?

He shook his head as they entered the living room, Asia and Issei were sat down and eating breakfast

His phone vibrated so he looked, his eyes widening before he got up and ran over to his bedroom. A moment later he came out in regular clothes before going out the door.

Trish: Any idea for what that was about?

Y/N: Maybe he had to do something with his club

Glancing over to Asia she seemed a bit lonely so Y/N went over, sitting across from her so she looked up and smiled, the memory of what he did last night lingering.

Y/N: I was wondering if you want to come out with me and Trish

Asia: It's okay, i don't want to ruin your time together by being a third wheel

Trish: I don't mind, we should get to know eachother more anyway

Asia: Well... i've done my homework for the break

Timeskip

They were walking around Kuoh, chatting and seemingly having a good time. Asia had memories come back from when they first met.

When they met again before she was taken by Raynere, he remembered none of that which upset her, to have their moments purposely forgotten.

?: Excuse me

Turning they saw someone with dark green hair and eyes that looked like they were closed. Asia gasped, remembering who this was

Diodora: Ah, i knew it was you

Y/N: Who... are you?

He glanced to Y/N, sensing the holy magic within him which confused him since Asia was a devil, however he kept his smile.

Asia: Y/N, i think we should go

Diodora: Please hear me out, ever since you healed me i've been searching for you

She turned around, going to walk away but he grabbed her wrist as he hid an irritated expression. Y/N pushed him back making the devil look to him.

Y/N: Look, she isn't interested bud-

He held his hand out, a magic circle appeared in front of his palm. Y/N was flung away making Asia and Trish look in shock before turning to Diodora.

Trish went to summon Spice Girl but something came flying towards Diodora, it cut his cheek before they looked over as hr held his cheek.

Y/N stood there as he held out a hand, a finger pointing at the devil as a small pink sacred gear with stars on it floated beside him.

Y/N: She isn't interested

The devil nearly lost his cool but let out a breath, his smile reappearing before straightened himself out.

Diodora: I suppose i'll talk to you another time, until then Asia

He vanished with a magic portal, the sacred gear disappearing as Y/N looked to his hand and arm, a small wound healing as his nail grew back.

Timeskip

Trish: Who was he...?

The two girls sat across from eachother at the table, Y/N had gone to his room to do the homework for the break.

Asia: He... before i was a devil, i was a nun. And my sacred gear allowed me to heal people so others came to gwt healed by me. One day a devil stumbled in and he was injured, i healed him but they found out and i was expedited from the church

Trish: He was that devil... why do you think he's looking for you?

Asia: Maybe it's to say sorry, it maybe he wants something else. But, i want to stay close to Y/N

Trish raised an eyebrow, confused to why before Asia took a breath and fiddled with her hands.

Asia: Lately, he gives off a vibe... one that reminds me of the church and i like that, it makes me feel at peace

Thinking it was probably due to the corpse part Trish let out a breath, looking to Asia before nodding.

Smiling Asia thanked her before Trish went up to Y/N's room, she went inside so he turned to look at her.

Y/N: Yeah?

Trish: About what happened...

She shut the door before sitting on his bed  he turned in his chair so they were facing eachother, Y/N rubbed his left arm gently.

Trish: The sacred gear you had... why wasn't it your old one?

Y/N:... I think the corpse part gave me a new one

Trish: What do you mean?

Y/N: It appeared out my arm, the sacred gear. A cut opened up on my arm before it came out

Trish: Then... do you think all of the corpse parts grant sacred gears.

Y/N: Maybe, but that's a scary thing to think about

She nodded before Y/N looked to his left hand, letting go of his arm he clenched his fist and sighed.

Y/N: No one else should have the corpse parts, you can only wonder of the danger it'll bring if they fell into the wrong hands

In another place, a man sat in a dark room with a few candles illuminating the place. He had a book in his hand, a dark glint in his eyes.

Diodora kneeled down, looking to the man who was sitting down as the man closed his book, glancing to the devil.

?: Mr. Diodora Astaroth, what is the purpose of this?

Diodora: Shalba told me... that once you collect them, you'll give the descendants their rightful places

?: That's right, what of it?

Diodora: Where does that leave me...?

?: There are many pillars of hell, need i remind you that you can be replaced by another? My actions are rightous, unclouded in the slightest. They're for the best for all species

A being appearing behind him, his colour and figure unable to be seen but it's eyes glowed in the darkness

Diodora: O-Of course, forgive me.

The man got up, walking over to the devil before he span what looked like an arrow with a broken shaft in his hand.

?: To assure your victory, i will grant you your own sacred gear. Use it against me, and you won't live to regret it

He pierced him through the back of his neck, choking on it as he ciughed out blood. Pulling it away the wound healed before he rubbed his neck.

Turning around the man sat back in his chair, picking up the book as he made the arrow disappear somehow.

?: Fail me in this, and you won't a place in the new world i'm making... Mr. Diodora Astaroth

(Lemme know what you think)
