A fifteen years old male could only stare at the various buttons spread out before him.

Looking back at the redheaded scientist he was visiting, he thought of asking a few questions.

"Hey, Shou-nii. What are these blue buttons for?" he asked curiously.

Without looking up from the weapons he was working on, he answered calmly. "It's for the fountains, Lambo. And also other water-related stuff."

"The green one?"

"For gardening reasons, like sprinklers and something like that."

"Yellow?"

"Solar panels and medic bay."

"Oh. So... what's the little blinking light mean?"

"It means... wait, blinking?"

Shouichi whipped up his head to look at the red blinking light with Lambo hovering near it.

Without a second thought, he abandoned the weapons and scrambled towards the nearest phone he could reach.

Pushing the buttons on the phone frantically, he clutched his stomach as it lurched, praying he would be able to talk.

Lambo just stare at his proclaimed big brother with worry.

"Hello, Decimo speaking" a voice crackled.

Thanking his lucky stars, Shouichi quickly told his intentions.

"Tsuna! Someone broke into 'that' place again!"

The line went silent for awhile... until a low voice came through.

"Oh? Do you know who?"

Shouichi violently shook his head until he remembered the person on the other end can't see him.

"Umm, no! I can't see anyone but the sensors detect mist flames!"

"I see. Thank you for telling. I'll handle this myself. Good day," and the line promptly went dead.

Shouichi let out a sigh of relief as he collapsed to the floor. Lambo quickly went near him.

"What was that all about?" he asked.

Shouichi could only let out a dry laugh.

"You really don't want to know Lambo. At least, not now."

Lambo only raised an eyebrow at that but said nothing.

Meanwhile, in a hidden part of the mansion, a creepy laugh filled the now desserted corridors.

"Mukuro~ Come out, come out wherever you are~"

Said person only shivered in horror in his hiding spot. Once he thought he was safe, he carefully exited his hiding spot, only to stare straight into a pair of orange eyes.

"Found you~"

The mansion had never heard a manly scream like that until this day.
