Chapter 5

After they stopover in ice-cream parlor they finally make it in front of Takesushi. Walking inside Yamamoto greeted his father who turn around immediately about to greet his son back when he saw his son carrying a boy who was happily and messily eating ice-cream.

"Takeshi Who's that boy?" Tsuyoshi laid the knife he was holding down on the counter then walk his way next to his son.

"Oh his Ryuutsuki I found him this morning in school and he was under my care for awhile, while we search for his parent. Is it okay if he stays here for awhile?" He hesitantly asks.

"No problem. As long as no one demands about the kid or police knocking in our door accusing you of kidnapping its ok." He half-joke.

Ryuutsuki look up at his ice-cream for a second. "Ahh Grandpa looks what daddy brought me." Ryuutsuki beam at Tsuyoshi showing him the ice-cream.

Stun by the boy he ask dubiously. "Takeshi did the boy just call you d-daddy?"

"Haha yeah." His nervously admit when his father look at him silently asking for any explanation. "That's the other reason why his with me he think am his father."

Tsuyoshi just shift his gaze to the two as if he was connecting some puzzle 'Will if you look closely he kindda look like Takeshi when he was young especially the way they smile were the same.' He thought before sighing he just ignore his finding and grin at his son. "Nah its ok now. Are you hungry? I will make you some sushi."

"Oh Me! Me I want some grandpa." Ryuutsuki energetically answer waving his hand up ice-cream in his other hand.

Tsuyoshi laugh at the boy enthusiastic. "My what a lively kid. Wait here I make you my delicious sushi. Ok?"

The boy nods its head. "Can I watch you work grandpa please?" He look with puppy eyes expression.

Tsuyoshi can not say no to the cuteness the boy was radiating. "Of course. But your going to sit on here you can see me work and also you're in save distance." Tsuyoshi hoist the boy up in his arm and sit the boy on the stall next to his working station, near enough so the boy can see him work.

"Oh I almost forget." Catching his father attention. "Were going to Tsuna's house today for sleepover is that okay?"

"Hmm Sure. If that the case I make more sushi so you can all share."

"Thanks dad." Yamamoto run to his room to get the stuff he needed.

^-^ ^-^ ^-^
30 minute later… Yamamoto finishes his packing after double checking his thing he descendent the stair duffel bag on his shoulder only to be face to a sight of his father laughing and talking to Hibari Kyouya who was doing a pretty good job in attending Ryuutsuki while the boy eat at the same time having a conversation to his father. Amuse by the scene he skipped next to Hibari who took a second glance at him then return to his task.

"Takeshi what took you so long you make Hibari-kun wait."

'Hibari-kun? How long had Kyouya been here?' Looking at them Yamamoto scratch his neck in embarrassment. "Haha sorry I took shower first and check properly my things before going down. I didn't know that someone was waiting."

"Don't sweat it Takeshi I entertain Hibari-kun while you are busy and also you did not mention that Ryuu-kun have been calling someone as his mommy." 'and also a boy at that.' He silently thought. He pause for a moment to study the two teen. "Haha If I didn't know any better I say that the boy can pass as your son. What with the similar glint when you to look happy and the boy look similar to Hibari-kun." Tsuyoshi pause again he had thoughtfully look.

Seeing the look his father has Yamamoto decided to change the topic. "Haha sorry about that but we should be on our way. Come on Kyouya." He grab the plastic bag that contain the sushi he was going to bring with him.

"Kyouya? Eh" Tsuyoshi eyes have twinkle in mischief. "Takeshi are you hiding something for me?"

Feeling the awkward atmosphere and the blush creep up his face Yamamoto cough lightly and open his mouth to say something only to gap at his father next declaration along side him was Hibari that also a gap but he automatically put his mask of indifferent before any one can see but you can see small blush forming.

"Hmm If that the case then Welcome to the family Kyouya-kun you didn't mind if I call you by your name right?" He said flamboyantly grins and winks at the two blushing teens.

Wanting to escape the awkwardness he hoist Hibari up gently and motion to the prefect to carry Ryuutsuki who swiftly obeyed without complain. Hibari nod his head in gesture of good bye to the elder Yamamoto.

"Haha Bye dad we are going now see you tomorrow." He usher Hibari out he can hear his father teasing word about 'avoiding the question' and 'explaining something when he return' that he cheerfully ignore.

Tsuna hurriedly run to open the front door when he heard someone knocking, he was greeted by Yamamoto's smiling face that he return but turn to shock when he so who was next to the baseball lover it was Hibari and in his arm was a bubbly Ryuutsuki.

"Hi Uncle Tsuna." The boy greeted smiling at Tsuna.

"Yo Sorry if we were late." Smiling sheepishly. "Here dad sushi for us." He pass the bag to Tsuna.

Coming out of his astonish he tentatively nod at Hibari's direction then turn to Yamamoto taking the bag at the same time opening the door wider so the three can enter . "Hi. Thanks we can eat the sushi later and don't worry about it the girls went out to buy something so it's ok if you arrive late." Tsuna explain leading them to the living room.

Yamamoto looking around to see whose already in there it was occupied by Gokudera, Reborn, Lambo, Ipin and Ryohei. "Hey guys."

"Hello." Ryuutsuki greet with smile also looking at his surrounding his gaze halt at the three kids in the room recognizing one of them he tug at Hibari's sleeve signaling he want to be put down.

"Ciaossu"

Jumping out of his sit Ryohei enthusiastically greet them. "Extreme you're finally here Yamamoto and you also brought Hibari with you. How did you extremely convince him to come? Oh hello little Ryuutsuki." He said with one breath making the other occupant look at him in amazement –except Hibari that give him a glare for being noisy, Reborn that was smirking and Tsuna's panic shout when Ipin cling to his pants and saw her activate her time bomb then proceeded to throw her outside -.

Hibari settle the boy down stride to the couch he nod to Reborn in acknowledgment and unceremoniously sit down he continued to ignore the other occupant he glare at Yamamoto a moment when said person bravely sat down next to him then he ignore him also he content himself in watching Ryuutsuki interact.

Lambo gallantly walk next to Ryuutsuki analyzing the kid. "Yama-chan whose this kid?" Not waiting at Yamamoto's replied he continuo. "It doesn't matter. Hehe am Lambo-san if you want to be my friend your going to be my servant." He get two answer a confuse look and a whack in the head courtesy of Reborn. Lambo immediately tear up mumbling "Gotta… be… calm…" Gokudera aggravate it more when he shout "That what you get stupid cow." He wails loudly. "WAAAHH…! I CAN'T!" Pulling the 10-year bazooka out his afro he jumps inside it covering his spot with pink smoke.

Hibari instantly grab Ryuutsuki away shielding him behind when Lambo pull the bazooka out. They heard some panting inside the smoke then a loud thud and a yelp when the person trip on something when the pink smoke clear they saw adult Lambo sprawl on the floor he slowly sit up rubbing his hurt face.

"HEII… adult Lambo are you ok?" Tsuna worriedly run to adult Lambo checking if the other has acquired other injury.

Adult Lambo blink first tried to process the concern question with his dizzy mind. "Yare… yare don't worry Vongola am ok for now." Unfortunately his mind has not yet fully processes his surrounding.

Confuse by the word 'for now' he ask again. "Eh what do you mean 'for now'?"

Instead answering Tsuna Adult Lambo practically look wildly remembers something spotting Yamamoto he hastily launch himself at the baseball lover tugging at the sleeve. "Takeshi-niisan! Hurry Hibari-san was on labor. NOW." He hysterically yells. When he felt the other become stiff he turns to whine loudly. "Why aren't you moving? Come on." He groans loudly in exasperation. "Your 'wife' is calling for you he asks me or more like threatening me to 'fetch' and 'deposit' you to him even if you are kicking and screaming his word not mine he also add that if needed I should just knock you unconscious so I can drag you he suggested that I use my electrocution or beat you to bump just to get you there, really your wife can be exaggerated sometime." He continued his ranting lost on his world not noticing the dark aura that forming in Hibari, confuse Ryuutsuki that was trying to peer behind Hibari, Tsuna's sweat dropping, bewilder Ryohei and Gokudera, and amuse looking Yamamoto and Reborn. "Yare yare really as if his in being giving birth to your son didn't freak you out lots of course you will run full speedahead to him. Goodness he alsothreatens me that if I failed the task he will skin me alive or his almighty praise 'I bite you to death' really am starting to question your taste Takeshi-niisan or your sanity for starter." He halt for a moment to catch his breath then he snort. "His just brave because of his tonfa if he doesn't it will be a fair fight. Tch I personally teach him a lesson he will never forget." He laugh evilly he was about to continued his heart pouring and revenge skim or more like misery situation and dream revenge when Hibari had have enough he swing his tonfa then smack the ranting teen in the head. Hard. "Ouch you-" Turning around to give the person some piece of his mind for hitting him for unknown reason his breath caught in his throat when he saw the culprit. "Wha-" Cutting himself he look at Hibari form up and down looking intently specially on the prefect stomach then look around his expression turn to recognition to horrified in second. "Don't tell me." He blurted out he nervously turn his gaze at the fuming Hibari.

"What. Did. You. Said. Herbivore."

The heavy atmosphere spread and the silent hung, oblivious by this Ryuutsuki tackle the cow clad teen making them stumble in the floor. Adult Lambo let out a surprise 'oof' and Ryuutsuki with his "Uncle Lambo." gleeful squeal recognizing his favorite Uncle –since Lambo indulge him in sweet food everytime they hang-out and it's EVERYDAY and the teen acted like his age so they are buddy-buddy-.

Before Adult Lambo thought to open his mouth to speak he was interrupted when the pink smoke envelop him again. Tsuna anxiously wait for the smoke to disappear when it did they saw Lambo crying and squirming under the weight of confuse looking Ryuutsuki trying to get out. "WAHH get off your heavy!" He was about to push the other boy when Yamamoto lifted Ryuutsuki up on his arm when he felt that no weight is holding him down he run toward the kitchen. "WAHH… MAMA THEY BULLYING LAMBO-SAN." The sound of his cry echo in the silent room and its occupant. The heavy silent only break when Nana goes in the living room with Lambo in her arm sobbing loudly.

"Tsu-kun why is Lambo-kun crying you shouldn't bully him." She scolded playfully hushing Lambo to calm him down.

"Ahh that's not it mom it was all misunderstanding." Tsuna try to explain.

"Shush Tsu-kun say sorry now. See Lambo-kun I scolded him so it's alright." She reassures him she turns to look at the new faces. "Hello dear your Tsu-kun's new friend right. I'm Nana his mom and who's this adorable boy?" She smiles at them warmly.

"Ah mom this is Hibari-san and Ryuutsuki his…" Tsuna pause he didn't know if he should say the word 'son' luckily Ryuutsuki help him intentionally or not.

"Hello. I'm Ryuutsuki nice to meet you." He shyly said bowing slightly smiling when he look at her again.

Cooing at the cute boy she squeal, pinching the boy cheek. "What an adorable boy you are and smart too." The three exchange look while Yamamoto beam, Hibari and Reborn hide there smirk. Nana set the sniffing Lambo down. "Well while waiting for the girls to return am going to go back in the kitchen to make cookie for the little once ok?" She didn't wait for the answer she just processed to make her way.

They can hear her giggle about dressing up, camera and picture later they can not help sweat dropping at the women's retracting back.
