"What?! Why me," Harlequin, also known as King: The Grizzly Sin of Sloth, shouts at he looks at Meliodas: The Dragon Sin of Wrath and Captain of the Seven Deadly Sins.

"Because you're the only one that looks 13," Meliodas tells him as he cleans a mug.

"You look like a kid too," King says as he floats a bit above Meliodas.

"But I'm busy looking after the Seven Deadly Sins' agency and running my bar on the side," Meliodas explains as he finish cleaning the glass.

"What about the forest? I can't leave it unprotected," King argues back, trying to back out of the mission.

"I don't think Elaine would mind watching it. If she needs help, we can always help her. Plus you can always use Oslo to hurry back if need be."

"Why not someone else?"

"Ban wouldn't fit in as a student, plus he stinks at teaching. Escanor and Gowther are helping Merlin with her experiments. And I need Diane to stay here and help me hold down our agency. Out of the seven sins, Diane is third person that I trust the most with making sure it runs smoothly. No offense King," Meliodas tells him.

"None taken. I'm just glad that I'm above Ban with trustworthiness over our agency."

"I HEARD THAT," Ban: The Fox Sin of Greed shouts from the kitchen.

"Sir Meliodas," Elizabeth Linoes, the third princess, says as she walks over to them. "Everything is ready for the bar to open."

"That's great to here. Oh yeah, you should probably head to UA now. I told them that you would be there in an hour."

"What?! Why didn't you tell me this earlier?!"

"I forgot. Also, Nezu want's to meet Oslo."

"I was planning on having Oslo take me there anyways. Flying would take too long, since I need to be there in an hour."

"Good. Here's everything you need to know about the mission. It also has your background so remember that," Meliodas tells King as he hands him a folder. "UA has found you a place to stay while you work on the mission. You and Oslo will meet them at the front gate of UA in...45 minutes. I would pack anything you need and then talk to Gowther."

"Talk to Gowther? Why," King ask.

"He told me that he needed to give you something for the mission," Meliodas says as he shrugs his shoulders.

"Ok? I'll go pack then," King says as he flies towards his/Ban's room above the bar. "I should stop by Gerheade's house and tell her about the mission. I have a feeling that Elaine already knows."

"Of course I do," Elaine: Holy Maiden of the Fountain of Youth, says as King enters his room. "Ban explained and I thought I would help you pack. We cann then visit Aunt Gerheade and tell her. I already texted Uncle Gloxinia and told him."

"Oh. Thanks Elaine," King says as he floats to his closet. "But um...did you have to tell Uncle Glox?"

"Well, I told Uncle Drole and you know that he will tell Uncle Gloxinia."

"Oh...ok," King mutters as he grabs his backpack. "Anyways, I better pack. We can visit Gerheade after I talk to Gowther. Apparently he wants to give me something."

"So what is this mission you're going on Harlequin," a voice says from behind them.

Elaine and King turns to see Oslo and Gerheade standing there.

"Aunt Gerheade? What are you doing here," King ask in surprise.

"Oslo told me about how you're going on a mission to UA. I thought I'd come and make sure you have everything you need. And yes, you need to bring underwear," Gerheade tells King.

"But they feel so weird and I don't like them," King says as Gerheade puts them in his bag.

"You are going to be wearing a uniform. It's probably not going to be as thick as your clothing. So yes, you are going to need to wear underwear."

"But-!"

"No 'buts' Harlequin. I am your guardian and you will listen to me," Gerheade says.

King sighs, realizing that he won't be able to win the argument.

"...Fine, but only this one time!"

"Good. If you ever need help, don't hesitate to call me, Gloxinia, Drole, Elaine or one of your comrades. I need to head back to the forest now. I'll see you later," with that said, Gerheade flies through Oslo's mouth and back home.

King finish packing everything he need into his bag. He grabs Chastiefol and they siblings head towards Merlin's laboratory, seeing as there was a high chance that Gowther would be there.

"You got everything Harlequin," Elaine ask him for the 5th time as they reach their destination.

"Yes Elaine. I promise that I have everything I need."

"You have money?"

"Yes."

"Clothing?"

"Yes."

"You didn't unpack the underwear, right?"

"I didn't. Gerheade would have my head if she finds out that I unpacked it."

"Ok. You got your phone and everything you need for it?"

"Yes Elaine. Why are you the one acting older? I'm the older brother," King says as they enter the room.

"Hello King, Elaine. Gowther is in his reading area," Merlin: The Boar Sin of Gluttony, tells them as she works on an experiment with Escanor: The Lion Sin of Pride.

"G-good luck w-with the mission K-King," Escanor tells him as he gives him a thumbs up.

"Thanks Escanor. I'll see you guys later," King says as he, Elaine and Oslo floats over to Gowther's reading corner.

"Just on time King. You have exactly 3 minutes to get to UA," Gowther: The Goat Sin of Lust, tells King as he looks up from The Princess Bride.

"Thanks Gowther. So, why did you want to see me."

"There is a high possibility that you don't know Japanese, the language that is spoken in Japan. I will be giving you the knowledge of the language right now. Tap! Broadcast," Gowther says as a pink light hits King in the head.

He blinks in surprise, then the knowledge about Japanese appears in his mind. He groans and grabs his head at the sudden onslaught of what Gowther gave him.

"A warning would have been nice when you were going to give me the knowledge. My head hurts now," King say as Gowther holds a Tylenol for him to take.

"This will help with your headache. You have 2 minutes and 42 seconds until you need to be in UA."

"Thanks," King says as he takes the Tylenol and swallows it dry.

"It will take the Tylenol 2 minutes to work. You now have 2 minutes and 19 seconds to get to UA. Want to say something in Japanese so that I know it worked?"

"Ok. Um," King says as he thinks about what to say. "I am the Pro Hero King: The Grizzly Sin of Sloth. I am also the Fairy King: Harlequin. My sister is Elaine and my Uncles are overprotective."

"Good, it works. You better head on out now. You have 1 minute and 51 seconds until you need to be at UA. Tata," Gowther says as he goes back to reading his book.

Elaine and King hurries off to The Boar's Hat to say goodbye to Captain and so that Elaine can spend some time with her boyfriend, Ban.

"Alright King! Safe travels! Make sure I get the weekly reports on time. Have fun," Meliodas tells King.

King waves goodbye as he flies into Oslo's mouth.

"Bafoo," Oslo says as they appear outside of UA.

"Yeah. I wonder where they are," King mutters as two people approach them.

"Grizzly Sin King. Nice of you to join us. I see Oslo is with you," a voice says as a small animal in a suit walks over to them. "My name is Nezu and I am the principal at UA High School."

"Hi. It's nice to meet you," King says as he smiles.

"Bafoo!"

"It is a pleasure to meet you too Oslo. I'm so glad to meet another animal with a Quirk," Nezu says as he smiles at Oslo. "Now then, follow me and I will show you to your apartment."
