Hibari Kyoya always knew he would eventually have a son. A strong, taciturn boy who would become respectable by growing up similarly to his father if Hibari had anything to say about it. And, if he was to have his way, Hibari knew he needed to keep outside, corrupted influences away from Katsurou.

So, it's understandable that he was infuriated to come back to the Vongola Mansion and find his son, alone, with R-O-K-U-D-OM-U-K-U-R-O in a small library.

When the door opened, Mukuro turned around, amusement shamelessly gracing his eyes. "Oya, oya, Skylark-kun, I thought you would be back later than this. Katsu-kun and I were getting along so well."

Hibari's eye twitched, seeing his three-year old son sitting on the indigo-haired man's lap. The enemy's lap. "Katsurou." The obsidian haired boy's head snapped up, vibrant teal eyes focused on his father. "What are you doing?"

Katsurou looked uncertainly up to Mukuro who nodded, faintly smiling which the three year old returned tenfold. The smile was gone by the time his attention was back on his father, stunning the Japanese man. "Pwayin' wif Mukuro-oji-san!"

Hibari resisted the urge to correct the boy's pronunciation, keeping in mind Katsurou had lost two teeth in the scuffle he won against the silver-haired herbivore's son two weeks ago. Akane had been livid when she saw her child, but Hibari couldn't keep the satisfied smirk hidden even in the face of his wife's wrath.

"That," Hibari hissed, jerking his head toward Mukuro, "is below an herbivore."

Katsurou tilted his head up to look at Mukuro. "But he'f teachin' me like you, Chichioya!"

Mukuro smirked. Any second now.

"Oh?" Hibari questioned icily, "and what pray tell could that abomination be teaching you, son."

"Thif!" A poorly made version of Hibird slowly started to meld into form mid-air, blocky mist flames flickering spastically to conform to their master's will. Eventually, a misshapen but proportional version of Hibird soared through the library's air space, spluttering mid-flight like an old air plane occasionally.

Hibari ignored the uneasy feeling in the pit of his stomach. "Hn, looks like your skills are deteriorating, Pineapple-herbivore."

A vein popped on Mukuro's forehead. "Oya? Quit trying to fool yourself, birdy. That wasn't my doing. Don't blame me for what you and your wife brought into this world."

Hibari stiffened, looking to his son. "…Katsurou?"

"Kufufufu, it waf pwetty for my firf time, wight Chichioya?"

The Vongola Cloud guardian went slack jawed, eyes uncharacteristically bulging. His heart skipped a beat, one away from cardiac arrest.

"Kufufu, it would be an honor to take responsibility for that quirk, however."

"Ne, ne," Katsurou turned to his Uncle, "whaf does 'Oya' mean?"

Mukuro grinned, hearing a thump towards the open door of the library before returning his full attention back to the budding illusionist on his lap. "Well Katsu-kun, 'Oya' is used when…"
