AN:I'm sorry for taking so long to update - I was stuck with this part, plus the world is in chaos right now.

Anyway, sorry if Mephisto is OOC (first time writing him) and the end sucks I think, but I hope you will enjoy this.

Stay safe, everyone!

Summary: Mephisto and Hibari meet.

Unseen and in dog form, Mephisto observed Hibari Kyoya, best friend of his half-brother, nephew of the Storm Arcobaleno and newly-appointed Cloud Guardian of the future Vongola Decimo.

He knew about the boy before, but he got curious when he found out Hibari Kyoya was childhood friends with the twins. After that, Mephisto decided to see the teenager (and maybe meet him) for himself, and there he was, in disguise, watching the mortal.

And hadn't regretted doing so. Hibari Kyoya was interesting. The boy appeared cold on the outside, but he cared for and protected those he called family fiercely, and was gentle to the animals. Not to mention, he was strong, and he would be even stronger once he mastered these Cloud Flames of his.

"Maybe you stop watching me and go over there?" The boy's calm voice broke through his reverie, grey eyes on the place where he was hiding.

Ohh, the mortal was good, the demon noted. Not many would notice he wasn't an ordinary dog, but this kid did.

Not upset in the least at being found out, Mephisto returned to his usual appearance, sitting down next to the teenager and introduced himself,"Mephisto Pheles at your service."

"Also known as Johann Faust V and Headmaster of the True Cross Academy where Okumuras are at the moment," Kyoya finished for him, reading a book and demon's reactions at the same time in case fight broke out. "And my name is Hibari Kyoya, but you're already know that."

"You're well informed."

"When you are best friends with the Okumura twins, one of which has the Blue Flames of the Satan, you tend to be prepared. I knew someone would come eventually, having discovered our connection. Not you certainly, but maybe one of the Exorcists or the demons of your father. "

"Hmm, I see. He told you of his origins?"

"Yes. And I accepted him as any friend should. Rin is not responsible for Satan's sins who may be his biological father, but not the true one — that's Fujimoto-san — and I will stand by him. He's still Rin, Satan's son or not. You have a problem with that? "

"Not at all," Mephisto said. "It's admirable, your loyalty. Rin is going to need friends like you if wants to defeat Satan like he told me," he stood up. "Well, time to go. It was nice meeting you, Hibari Kyoya. Ciao!"

With these words, he snapped his fingers and transformed back into the dog, pink smoke and all for effect, before going back to wherever he came from.

Left alone, Hibari rolled his eyes at Mephisto's theatrics. What a clown. Okumura was right about that. Dangerous one, but still acts like a clown. It's must be familial since Rin acts similar most of the time.

He's lucky what Mephisto just wanted to talk. From now on, he should be more cautious. Who knows what and who will come next to use the friendship between him and Rin.

All in all, Demons and all what was related to them, was weird.

How Okumura dealt with all this craziness?

Only God knew.

He really begins to prefer his kind of trouble — walking pineapples, Vongola, Flames and all.

With these thoughts, Hibari returned to reading.
