The Difference of the Mist

Sawada Tsunayoshi was doing his usual job (signing paperwork) when a crash was heard from the room and followed by a groan. "Ouch, what hit me this time?" blinked at the non Italian voice with a little accent, Tsuna looked up from his papers to the corner of the room only to see a lanky boy around 13-14 years old with pale skin, messy black hair, wears a faded orange t-shirt and denim jeans, and currently clutching onto a bookshelf for support.

"Hello." The boy notices Tsuna, "Are you alright?" The brunet asked in English, he stands up but still didn't approach the boy. Normally the Vongola Decimo would be on the alert if someone suddenly appeared in front of him, but because of his Intuition didn't give a warning, and the person in front of him was the younger than him, Tsuna tried to calm down.

"Uhhh..." the boy tried to talk, his eyes looked around carefully. Realizing where he is, the boy mumbled "Oh great, I landed in someone's house." then finally turned his attention to Tsuna, "You will forget about meeting me today," and the boy snaps his fingers.

Tsuna gave him a strange look. "Are you really okay?" is it possible that the boy hit his head somewhere?

This time, the boy looked confused and shocked. "Why isn't the Mist working?!"

The brunet looked at his 'visitor' surprises, "You're the Mist user?" It can't be... The boy is from Mafia?! It explains how he can suddenly appear without Tsuna's knowledge, only the Mist user can do it.

The fourteen years old boy frowned, "You know about the Mist?" his body becomes tense and brown eyes widen in alertness, "Who are you?!"

Tsuna rolled his eyes at the unknown boy, "I should be the one asking, it was you who suddenly appeared in my room from nowhere. Anyway, I am Tsunayoshi."

The boy's glare lesses, "My name is Nico Di Angelo." paused, "Can you tell me where I am? What country?"

"You're currently in my mansion in Venice, Italy," Tsuna answered patiently. If he's someone who has a bad temper (like his Storm), he has blown up to that boy.

The boy, on the other hand, just sighed hearing Tsuna's answer, "At least the right country this time." this time, he said in Italian.

"What do you-" before Tsuna finished his words, a knock on the door made him and the boy freeze.

"Hide!" the brunet whispered to the boy.

His day definitely didn't go as planned. Seriously, Nico Di Angelo needed a break.

Chiron had been giving him a quest, to look for someone who is suspected of being a demigod. Why Nico? Well, that's because Nico himself submitted it' this time the mission is located in Italy, in other words, his hometown. And this mission will be faster because the son of Hades is the only one who can shadow travel

Percy had offered to accompany him, but Nico waved him off.

It had been a month since the war against the Mother of Earth. The Seven were busy with their respective activities and quests in Camp Half-Blood and Camp Jupiter with Percy and Jason as leader of the demigod at both camps. Thalia has been away with the Hunters like usual, and Nico himself? Well, if he is not too busy helping his father, Nico usually spends most of his time in CHB, watching his cousin training the new and young demigod (sometimes he also helps give 'lessons' to the arrogant newbies).

"It's a simple quest," he said to Percy. "Don't worry."

Of course, for the demigods, there is no such thing as a 'simple quest'.
