The five were in Dumbledore's office still covered in grime and dirt. Dumbledore was returned to the school after news of two students being taken into the chamber of secrets. They were taken to his office after one of the teachers saw them all.

"Ingenious. Simply... ingenious", Dumbledore says inspecting the stabbed diary. "Of course, Tom Riddle was probably the most brilliant student Hogwarts has ever seen. I taught him myself fifty years ago. After he left, I occasionally heard stories of his activities and dark rumors, but after a while, even the rumors stopped. When he finally resurfaced as Lord Voldemort, most people had completely forgotten the clever Head Boy he'd once been", Dumbledore says with a wistful expression.

"I didn't know whose diary it was, sir. I swear. I found it inside my cauldron", Ginny says before turning to the other people in the room, "The day we all went to Diagon Alley...". Harry had a face of realization as Ginny continued turning back to the headmaster, "But I understand if... given all the trouble I've caused... if you".

"Wiser wizards than you have been hoodwinked by Lord Voldemort, Miss Weasley. No, I think you've endured enough. I would suggest a bit of bed rest, and perhaps a large mug of hot chocolate. I always find that cheers me up, but I believe it's time we discuss Young Kurayami's position here", interrupted Dumbledore reassuring the girl. "I believe that Mister Potter and Miss Weasley here witnessed Kurayami's Ability".

"Ability, what? Professor Dumbledore, what are you talking about?", Molly asks confused.

"When Tom was about to take me into the chamber Kaiyo walked in and he did something to the shadows. They started to wrap around Tom before I-", Ginny recalls.

"Wait—the shadow dogs in the chamber. You saved Ron and me in the forest and last year when we fought the troll!", Harry realizes looking at Kaiyo in shock.

"Dumbledore, what is the meaning of this", Arthur demanded.

"Let me start at the beginning then", Dumbledore started. "Before the start of last term Severus and I left for Japan to recruit help from people much more powerful than you could imagine—Ability Users. I struck a deal with the Port Mafia in Yokohama to have one of their assets sent here to Hogwarts for protection. Kaiyo is the asset they agreed to send here as a bodyguard of sorts", Dumbledore explained.

Everyone in the room was frozen in shock at the information. The adults were more concerned if anything. This boy, this child was sent to a foreign country to protect them. They all stood in silence before Dumbledore continued.

"Kaiyo will be here for all 7 years as an undercover student. I expect that none of you will say anything about this", Dumbledore says with a serious tone, the gentle grandfatherly tone of voice gone. The people in the room nodded their heads—the Weasley parents albeit hesitantly.

"Kaiyo, Escort the Weasleys to the infirmary to get Ginny, Ron and yourself checked out by Madam Pomfrey", Dumbledore said to Kaiyo. He gave a short nod before walking out with the Weasleys following behind him.

They walked in silence for a couple of minutes. Ginny was fidgeting with her fingers. Ron was staring at the ground as if it was the most interesting thing in the world. The two adults in the hall were staring at the boy leading them down the hall.

"Kurayami- um. Kaiyo?", Ginny asked nervously.

"Yes", Kaiyo responded.

"Thank you... for saving me", Ginny said with more gumption.

"... You have nothing to thank me for", Kaiyo said, walking along not turning his head.

"Come now dear. You saved our little girl. We owe you and Harry that and more", Mrs.Weasley said as they walked up to the infirmary.

"We're here", Kaiyo said, opening the door and letting the four in before walking in himself.

"Oh dear we're busy- Oh my! Come, come in. What on earth happened to you a lot?", Madam Pomfrey said, ushering them in. She ushered Ginny to an empty cot and her three family members followed.

"Kaiyo... Dear is there someone you'd like me to get for you?"Madam Pomfrey asked as she led him to another empty cot. He shook his head no lightly. "I'll be right back stay here", she said as she left to go check up on Ginny.

He watched as she walked away and she was at her cot. He closed the curtains around his cot. After he was sure the curtains were closed he took off his robes, took off his green vest, and unbuttoned his shirt.

He used his shadows to look at his back to see the damage. He had a large bruise on his right shoulder blade where his body collided with the ground. He had a slight headache from when he was knocked out. He let out a light sigh before taking his shirt and putting it back on, but he didn't button the shirt back up.

"All right now let's get you all fixed up", Madam Pomfrey says before taking off the shirt. She inspected his bruise before lathering a cream of some sort onto his bruise. The light throbbing in his shoulder slowly stopped.

"That should deal with that nasty bruise on your back. Now if you feel a headache forming that is normal for someone knocked out", she said. "You should be all good to go, just remember to rest", she said before leaving the closed area.

He put on all his clothes before leaving. He walked down the halls before rapid footsteps came up to him.

"Kaiyo!", Kaiyo turned around to see Harry running up to him before they were lying on the ground. "Itai...", Kaiyo says quietly as he tries to sit up. The two were on the ground with Kaiyo slowly sitting up and Harry leaning over his arm on either side of his torso.

"I'm so sorry. I didn't mean to crash into you again", Harry says embarrassed with a light pink blush getting up and reaching a hand out to Kaiyo.

"It's fine. I suppose you have questions for me?", Kaiyo asked, fixing his clothes before crossing his arms.

"You're right I have a lot of questions, but can we talk about this with Ron and Hermoine-"

"Absolutely not!", Kaiyo interrupted.

"Why?", Harry demanded.

"You weren't even supposed to know about my mission let alone Weasley", Kaiyo says with a glare. "The more people who know why I'm here the more my undercover status is at risk".

"Fine... Then after the feast I want you to meet me at Hagrid's hut", Harry says. His tone left no room for negotiation.

"Fine... After the feast, I'll go to Hagrid's hut. If you're not there I won't wait for you", Kaiyo says relenting to Gryffindor. He turned back around walking to the Slytherin Common room.

The room was empty. He assumed the entire dorm was already at the feast waiting for the petrified students to join them. He walked into his dorm room before grabbing a clean uniform and walking into the shower.

He quickly stripped before stepping into the warm water. He let himself relax for a moment before reality came crashing down on him and he collapsed to the floor of the shower.

The boss would know he blew his cover...

He'd be returning to Yokohama this summer not long from now.

What'll happen to him...

Fear welled up in his system. He was terrified of returning to Yokohama. Reporting to Mori how he managed to expose his cover to two students.

The hot water shocked him back to sanity as the heat began to burn. He turned the nozzle and the water started to cool down. He finished his business in the bathroom, changing and leaving the dorm.

He walked in as Hagrid was giving the three a hug and complaining about an old owl. He walked over to the Slytherin table before being tackled by a short blur.

"Pansy?"Kaiyo questioned the blur that knocked him over.

"Where have you been?! Professor McGonagall and Snape were telling everyone to start packing up and how two people were missing and no one's seen you in days-", Pansy says before a hand covers her mouth.

"We were all worried about you", Theo says from beside her.

"I...I'm sorry for making you all worry", Kaiyo said, looking solemn. They continued with the feast as Dumbledore announced the cancellation of their exams. They continued with the feast as Kaiyo would glance at Harry occasionally when the boy returned. Soon enough the feast ended and Kaiyo prepared to meet Harry.

"Kaiyo?", Draco asked the boy concerned.

"Yes?"Kaiyo responded, turning to face Draco.

"Is there something you aren't telling us?", Draco asked. Kaiyo froze at that moment. He couldn't answer. He couldn't lie to his face not like this. His mouth trembled as he tried to say something but could only stumble on his word. Before he smiled, but Draco could see it never reached his eyes.

"I'll be back in a bit, I promise", Kaiyo said. Drac didn't know why a chill came up his spine when he saw that smile.

"Okay", Draco said reluctantly, turning to return to the dorms.
