Summary: It was an unspoken message. Its shape was always shifting but it was always understood. Everyone knew how to respond and dutifully did so. No one wanted to meet his wrath. Moreover, it was amusing to see how one stayed oblivious to it. Set 8YL! following the end of the manga.

A/N: It is an obvious Part 2, a bit silly. Hope that it will entertain a few of you. Please enjoy!

It was an unspoken message. Its shape was always shifting but it was always understood. Everyone knew how to respond and dutifully did so. No one wanted to meet his wrath. Moreover, it was amusing to see how one stayed oblivious to it.

The second time, it started with the Guardians. To be specific, it started with Lambo.

It was no secret for the family that Tsuna fell asleep on his work sometimes. One day, Lambo came into the office to complain about the lack of grape candies in the kitchens –Tsuna's order in an attempt to stop his youngest Guardian's unhealthy obsession- and found his big brother asleep, his head in his arms beneath a stack of signed documents. Being his usual mischievous self, Lambo immediately got an idea. Moving stealthily –not that Tsuna would wake up, since Lambo was family, his Hyper Intuition wouldn't bother him-, he reached for one of the pens on the desk. With an amused smile, he drew some lightning on his brother's face and a form looking vaguely like the head of his animal box –Gyûdon.

When Tsuna began to stir, Lambo hastily put down the pen and went in front of the desk, taking the most convincing innocent expression on his features.

"Tsuna-nii!" He called as he was used to since he reached seven years old. "You fell asleep on your papers again."

Tsuna blinked, rising his head. Yawning, he sent a smile at his young Guardian and stretched his stiff muscles. Lambo casually approached, one of his eyes closed. His lips twitched as he suppressed a smile in an attempt to keep his lazy demeanor.

"Good morning, Lambo." Tsuna greeted him, standing up. "I'm lucky that you awoke me. I'll have some time to change."

"Better me than Reborn." Lambo snickered.

A knock on the door followed by an "Excuse me, Jûdaime" alerted them of Gokudera's presence. The Storm Guardian entered the office and froze when his eyes fell on Tsuna's face.

"Good morning Hayato." The Sky boss smiled sheepishly, knowing that he had been caught by two of his Guardians. He tilted his head when he didn't receive any answer and noticed the stare. "Do I have something on the face?" He asked, unconsciously reaching for his mouth, thinking about drool.

Lambo met Gokudera's gaze and a silent message passed between them. When the Storm turned away to answer his best friend, the Lightening knew that his fellow Guardian wouldn't say anything. He failed to suppress his grin that went thankfully unnoticed.

"The Shimon are here, Jûdaime." He announced, avoiding the question and keeping a straight face even as he counted the numbers of lightening drawn on his boss's face –15. "I'm afraid you don't have time to change." He added then, just to have the pleasure to watch everyone's reactions.

Tsuna's eyebrows rose. "I didn't expect them so early." With a look at his watch, he instantly understood why. He had slept longer than he had expected. "Thank god Reborn isn't here or he would have taught me another lesson."

Lambo let escape a short laugh at that, seeing the almost horrified look on the brunet's face. That and Reborn would have probably reminded him that a "Mafia boss is always alert, even when sleeping." No doubt that the hitman would have taken great pleasure to also teach this lesson, especially considering how "a boss should always be perfect". Tsuna straightened his suit a bit. Enma wouldn't mind his slightly neglected look but he would prefer to avoid Adelheid's disapproving glance if she was there too. He left his office with both of his Guardians, oblivious to their amusement.

People were staring at him. Not that it wasn't anything new –being Vongola Decimo and all- but usually, they didn't giggle when meeting his eyes. On his way to the meeting room, the few maids, butlers and guards Tsuna met, quickly averted their eyes. Some giggled while others, more reserved, felt their lips twitch in visible amusement. At one point, a few feet before his destination, Tsuna thought that he had indeed something on his face. However, if that was the case, Gokudera or some of the boldest employees would have warned him. Shrugging and deciding to think about it later, he opened the door and smiled warmly, immediately spotting Enma.

The Shimon boss who was talking with Yamamoto, the Rain Guardian, turned cheerfully towards Tsuna. Whatever he wanted to say suddenly slipped from his mind when his eyes landed on his friend's face. Yamamoto instantly burst out laughing while Adelheid who had decided to accompany her boss glared disapprovingly at the Vongola Boss. Tsuna stopped walking and sent them a puzzled look.

"Tsuna-kun," Enman began, unable to hide his chuckle, "you didn't look at yourself in a mirror before coming, did you?"

Lambo went to join Yamamoto, quietly explaining him what he had done. The Rain patted his head in affection and amusement.

"Is it that obvious?" Tsuna asked sheepishly, ruffling his brown locks.

These few words were enough for Lambo, Yamamoto and Enma to openly laugh and Gokudera let his amusement show on his face. Adelheid simply glared harder, folding her arms.

"What?" Tsuna raised his eyebrows, watching them. "What did I do this time?"

Adelheid sighed in exasperation. Her ring briefly shone as she created a thin and reflective shard of ice. She handed it to him with a pointed look. Tsuna accepted it easily since he would finally obtain his answer –and promptly stifled an exclamation. His eyes widened as he noticed the drawings on his face. He instantly turned towards his Lightening.

"Lambo! Thank God I didn't have any important meeting with other Bosses!"

His Guardians snickered at his reaction.

"Come on, Tsuna-nii, you know I wouldn't do that if that was the case." Lambo retorted without missing a beat, smiling lazily.

"That sure explains everyone's reactions…" Tsuna sighed, passing a hand on his face and giving the shard back to Adelheid. "Thankfully Reborn isn't there to see this-"

"See what, Dame-Tsuna?" A deep voice interrupted him behind him.

Tsuna stiffened and a quick look of horror crossed his face. Trust the hitman to have the worst possible timing. He sent a pleading glance at Enma who winced in sympathy but crept away. He would do almost anything for Tsuna but going against Reborn? Nope, that was simply impossible. The man was just too terrifying. The Guardians weren't helping too. Upon seeing Reborn, Lambo had promptly vanished, as fast as his element. Yamamoto greeted cheerfully the hitman, deliberately ignoring the desperate look in Tsuna's eyes and swinging an arm around Gokudera's shoulders, successfully distracting the Storm.

Tsuna's shoulders slumped in resignation. He slowly turned around, facing Reborn with a weak "H-hello Reborn…" Reborn stared at him in complete silence before a smirk quirked his lips widely. Tsuna shuddered and went as white as a sheet.

"It seems that you need me to teach you some lessons, right, Dame-Tsuna?"

Tsuna could do nothing but shriek.

The following day, Tsuna woke up with chameleons everywhere on him. Face, arms, legs, chest… Every single area on his skin was covered with Reborn's favorite reptiles in indelible marker. The Vongola Boss cursed and sulked for the entire time the drawings stayed on him, pointedly ignoring his lover's smug look and glaring at the surprisingly diminished piles of paperwork –with three of his Guardians sent away, Tsuna's workload had shrunk, courtesy of Reborn.

Everyone knew that no one but Reborn could mark the Vongola Boss.
