Right after I sent them back

"Look you guys we're in the Capital."
"We can see that Asta."
"What do you guys say we patrol for a bit?"
"Good idea Yuki." Nero praised

After 10 minutes of them walking around the capital hoping to rack up some merits they finally came across something

"Cap! Look over there. The one with the robe. He has a demon with him."
"Is that so? Finally we found someone. Yuki, whoever beats that guy first wins."
"Stakes are still the same!"

"Yep all brawns and no brain." Nero and Noelle insulted

• Both Yuki and Asta jumped on the mysterious man hoping to take him down but was stopped and were taken down by lots of shadow hands that pinned them down •

"Sleep now young ones"
"Wait you?.." Yuki asked but before he can answer he passes out
"Get back here damn it!" And Asta also falls

•The two made a big scene in the middle of the capital and the residents freaked out since the Captain and Vice Captain couldn't take down a single robbed man. Everyone avoided the mysterious man and made a way for him since he was just about to enter the palace. He was met by a familiar face though.•

"Asta-Kun. I know you did your best. Now let me handle this."
"Oh sir Vangeance."
"You...! How do you know my name?! Explain!"

• And thus the man took off the robe and revealed himself •

"...! You're back. Welcome back Natch. How did it go?"
"Pretty well sir! Do you happen to know where the captain is?"
"The current or the past one?"
"What do you mean?"
"Well.... if you're talking about Yami. You should go see him inside the Wizard King's room, and if you're looking for the current one. He's currently right there on the floor." He answered pointing down on Asta

"So he's finally made it huh? I'm so glad. Please excuse me for a bit. I'm going to stop by our HQ to drop my items off then I'll visit Yami"

"Go on right ahead. I'm sure you'll be surprised to see lots of unfamiliar faces there. Have fun and welcome back."

"Thanks a lot sir, and I can't wait to meet my new juniors."

•There's Nacth again as he snatched Asta and Yuki on the floor with his shadow hands and carried them all the way back to the HQ.•

"Hmm.... hey miss. That robe you belong to the Black Bulls right?"
"That's right now who are you and what are you planning on doing to our captain?" Noelle asked

•Nacth then fully takes off his robe to reveal the infamous black bull robe. •

"There's no time to explain right now. Let's save it for later once we get to the HQ. Oh and by the way, do you know where it is? Henry do like switching the place all the time."

"Uh-... sure. Nero. Come here enough Mongu seeds for now, let's head back."
"Nom?"

Back at the HQ

•*knock* *knock*•

"Welcome back, you four and Oh? Who's this?"
"Hey there Mrs Charlotte. What are you doing here?"
"Oh it's you. Uhh Vice Captain of the Black Bulls right?"
"That's right ma'am. I heard you retired from you're work. Oh and one more question, what are you doing here"

Instead of answering straight-forwadly, she instead showed her official Black Bulls robe.

"Pfft... Hahahahahah!"
"What's so funny you jerk? Is there something wrong with Mom? Huh?!"
"Calm down Magna. Let's hear him out first."

"Sorry sorry ma'aam. That just caught me off guard. I mean, you lead an all girls squad so I thought it might be impossibe for you to have a family since you've hated men."

"Lots of thing happened when you were gone. Hubby's kinda working right now, managing the kingdom."

"Oh you mean Yami? Why him though? He's an indecent person. He's reckless, violent, and verbally hurtful."

"Oh that will always be a secret. Now what business do you have with those two?"

"These guys? Oh these two tried killing me so I knocked them out and I had this girl take me here. I'm just here to drop my item off and visit Yami."

So Nacth dropped off his belongings and made his way back to the royal capital and visit Yami.
Before Nacht could make it out of the HQ, Asta and Yuki awoke and proceded to rush Nacht again.

"You never learn do you? Can't be helped then"

Shadow Magic: Shadow Binding:
Releases lots of shadow hands from the ground to pin down the targets

"Listen Kids. Do you know who I am?"

"No! Who are you?! What business do you have with my members!"
"Shut up for a seccy Cap'. Yo whoever you are inside that grimoire, how you doin'?"

"Ah! So you must be a demon! That's really interesting. Where's you're host?" Nacht asked
"Right here." Yuki replied by pointing at Asta
"Ohh... where's your Weg?"

A weg is basically the horn that grows when Asta enters his black form

Asta looked at Yuki signaling him to enter black form. Yuki caught on to this and lent him his power. During the demonstration their power increases until it reaches it peak. Asta noticed a major difference, he now has two large horn instead of one

"Ohhh... fantastic. Leviathan, show them."
"Whatever you say....."

"THAT'S IT. IT'S YOU! LEVIATHAN!"

"Who are you? How to do you know my name?"
"Oh let's just say we're old acquaintance."
"Hmmm..... do you happen to be a stupid demon named Satan aka Sin of Wrath who stole all the glory from me?"
"Bingo! Wait what...?!"

"You're still an idiot up until now"
"Tch... at least I have a physical body. Unlike a coward like you staying inside a grimoire."

"Yo how y'all doing?"

"Ah shit it's him again." Asta complained

"I've already shut your mouth many times, want me to do it again?"

"Try me—! Mhpmh mhphm!"

"Take him away Noelle. Right where we're we? Oh right. Leviathan was it?"

"That's me. What do you want?"

"Girl or Boy?"

"I'm assuming you mean my gender, if so I'm a girl"

"Huh?! I thought all demons are boys!"
"Shut up Natch. You sexist piece of crap"

"Mhmhp mhpmh mph"
(I thought so too.)

"What'd he say?" Yuki questioned

He said he thought so too

"Sexist. How do you think we populate?"

*sigh* Release

"*pant* *pant*. I dunno Magic maybe?"

I'll cut it off short here for today. I know this has nothing to do with Asta and Noelle but I promise the last chapter would have at least 5000 words and I'll start on a huge time skip. Like the 6 months time skip for example. Don't worry you won't get lost reading it. I'll try to explain it throughly as we go on. That's it for me bye
