10: Bitter Apologetic Forgiveness

"Father" Ren whispered as he poked his father on the arm.

Turning his head away from the window, Hibari asked his son gently "What is it?"

Hopping onto the sofa his father was sitting on, Ren's eyes sparkled "I want to go to the park!"

Gracefully standing up, holding his son's hand, Hibari spoke with love "Do you want crepes?" knowing how much Ren adored desserts.

Nodding, the father and child walked out of the house, silently, towards the park.

"Hey, Father" Ren suddenly asked

Looking at his son, Hibari noted for his adorable son to continue

"I heard, from Dr Shamal, the last time he came around that you were a Universal Donor."

Hibari nodded, not quite sure how his son heard.

"Universal Donor, what's that, Father?"

"Sawada…Tsunayoshi?" Ren slowly stated, as if the name was taboo. Close anyway. Taking the lollypop out of his mouth, the young teenager narrowed his eyes, immediately suspicious of the man before him. "What do you want?"

Slightly taken aback by the frightening nature of such a young boy, Tsuna's eyes widened a little before sticking his hand out "It's nice to meet you" his eyes smiling.

Saying nothing, nor moving, Ren merely stared at the Vongola Boss.

It was a little later in which Tsuna took his hand back, realising that the child before him was in a foul mood and did not wish to cooperate. Much like Hibari-san when he was in his teenage years.

"Ren," Tsuna began, his eyes never leaving the face of said teenager "Why won't you join us?" A simple question that's to the point.

Ren scoffed, silently thinking Not him too. Putting his lollypop back into his mouth, his eyes not as narrowed and slit like cat eyes, Ren looked away, at the clouds before back at the Guardian of the Sky. "Why do you want me to join so badly?"

There was a silent and uncomfortable pause as a pair of eyes watched another pair of eyes. Tsuna was thinking, he did not know how to answer this question, especially to someone such as Ren. Dumbfounded that he could not put his thoughts and emotions into simple explanatory words, Tsuna frowned.

"You're forgiven" Ren said, calmly.

"What?" Tsuna asked, his eyes widening slightly with confusion, obviously puzzled with how the conversation had trailed to forgiveness.

"You're forgiven" repeated the rather impatient child.

Another hesitative decision, Tsuna asked, wearily "What for?" his tone indicating that he did not believe that he needed to be forgiven by such a child, especially when this was only their first meeting. It was not like Tsuna had done a lot of terrible things, no he hasn't.

Sort of half-knowing what Ren was hinting at, Tsuna asked, he wanted a confirmation, and the best candidate to get the confirmation from was none other than Hibari's very own treasure, his child. "Is this about Mukuro and Hibari-san?"

Ren sighed, taking a seat on a nearby bench, checking his watch. "Father once said, when I meet you, and if there's nothing to say, I was to tell you that you're forgiven."

Tsuna nodded, taking a spot next to the rather young boy.

Twirling his strawberry and cream flavoured lollypop in his mouth, Ren kept on talking "He said it's a part of my job to tell you, that you're forgiven, for what, I'm sure you know what it is too. For that part in your heart" Ren takes a finger and points to his chest and draws a circle "the heart that holds your conscience, guilt, perhaps, he said, that you would have felt guilty for knowing that Mukuro had left him for you." Ren stretched back, relaxing his limbs "But, Father said, it's not your fault, so you're forgiven."

Popping his lollypop from his mouth, Ren takes a look at Sawada Tsunayoshi, his hair hiding his eyes, his head nodding softly, his hands crumpled in fists, the knuckles showing under the pale skin; obviously knowing what Ren had said was really what he had thought of before.

"You have pale skin" Ren commented Father had pale skin too…

Tsuna looked up, query with the sudden comment. "Wha-?"

Jumping from the bench, Ren stood up, alarm on his face "Ah! Before I really do forget!" he said, holding his head, and in his case, just this time, he just does not want to remember, just not the blood, memories of Father's blood.

Narrowing his eyes further, the Cloud Guardian turned around, facing the boy that bore the same silky black hair. Embracing him fragilely as though he were to break, Hibari Kyoya spoke softly into his ear, his voice projecting the pain and sadness he was holding onto. "Look after Hibird for me" His arms tightened as he continued "If he asks, tell him I'm sorry, for everything."

Not knowing what was happening or going to happen, the young boy nodded, holding tightly onto his father's shirt for he felt like he'd never have another chance to do so.

"Father also said, Sorry, for everything" whispered Ren, trembling as he stared at his palms, eyes widened.

"Everything?" Tsuna whispered in a daze as he watched the son of Hibari cradle his head in pain, obviously wanting to forget that certain part of his memories.

"Everything?" Ryohei asked, his voice thick with doubt

"Concerning me and him"

"Relationship" mumbled Ren as he brought himself back to composure, taking another quick glance at his watch, "Please, please" Ren begged "forgive my Father!" his lollypop dropping from his mouth, tears streaming unwilling down his face, in-synch with his heart, his thoughts and his memories.

"Forgive Hibari-san?" Tsuna asked, his face showing disbelief, and somewhat a little relieved, for being forgiven or for being asked for forgiveness, Ren could not see, his eyes were blurred with tears, his knowledge and understanding of his Father. His pain. He understood it all, he just could not feel it; the pain his Father bore.

Kneeling down, the Tenth placed his hands on the child's shoulders, an attempt to stop him from crying, an attempt to encourage Ren to speak to him, to answer Tsuna's rather desperate answers.

Holding onto Tsuna for support, Ren was kneeling as he hung his head down, crying silently. Somehow, the young teenager just knew, he just knew that he would probably not make it to school today.

Cursing softly, Mukuro ran out of the house he shared with Tsuna, unable to find him anywhere, Mukuro hastily pulled out his cell phone, frowned as he noticed that his phone was as good as dead, out of batteries. Shoving it back into his pocket, Mukuro came to a halt on the street next to his. "What the?"

"Mukuro?" Yamamoto asked, astonished

"Aren't you suppose to be running an errand for the tenth?" scoffed Gokudera, clearly unimpressed that he had to see the cursed illusionist so early into the day.

"Where's Tsuna?" Mukuro asked, alarmed with worry and confusion.

"Oi, oi, calm down to the EXTREME man!" Ryohei laughed, slapping Mukuro on the back.

Turning around, Mukuro looked at Chrome "Chrome darling" Mukuro ordered

Answering with unblinking eyes "Yes, Mukuro-sama?" Chrome took a step forward, ready to obey the person who once saved her 'pitiful' life.

"Tsuna-" Mukuro heaved as he felt a familiar weight clamping onto his back.

Gritting his teeth, Mukuro pushed Lambo off his back, "LAMBO!" the holder of the Mist Ring threatened.

"Oi! You!" Lambo pointed towards a clearly infuriated Mukuro "Where's the lollypop you promised me!?"

Pinching Lambo on the cheeks, Mukuro gritted his teeth, hissing "When did I PROMISE you ANYTHING?" unaware of the crowd of people backing away from Lambo and him. However he stopped as he realised that he had more important matters to address, he threw Lambo aside, though it was rather hard, as he had grown up to be quite the tall man.

Ignoring the cries of Lambo and suppressing the popping vein on his forehead, Mukuro forced a 'gentle' smile on his face, "Chrome darling"

"Mukuro-sama?"

"Where's Tsuna?" And why the hell are you all gathered in ONE SPOT!?

Chrome stayed silent as Yamamoto tried to explain, without really telling lies, but not the whole truth either. "Tsuna is out, on business"

Shifting, Mukuro did not buy Yamamoto's lousy explanation, so he decided to ask, in another way. "Then what are you all doing here?" a direct command, demanding for reasonable answers.

Clapping her hands together, I-pin smiled shyly "We're here on a-"

"DIVERSION!" shouted Lambo, bursting with happiness that he could actually answer a question. However his happiness did not last long as I-Pin and Gokudera simultaneously hit Lambo on the head, furious.

Raising an eyebrow, Mukuro's eyes narrowed "from Ren?" realisation slowly sinking in, cursing his outstanding understanding of Tsuna, Mukuro believed that it might have been better if he had not said immediately that Tsuna was on business, with Ren, for he really did not enjoy being pinned down by his fellow companions as he felt his body go numb, and he disliked the taste of dirt in his mouth even more so. "Shamal" Mukuro managed to gritted out

Laughing, Shamal apologised without sincerity "Sorry man, but we just gotta immobilise you for a while" as he closed his closed his pack of pills, owing up to his title, 'Trident Shamal'

"Universal Donor, what's that, Father?"

"There really is no real Universal Donor. Just a belief is all."

"Belief?"

"Experimental, I suppose could also work as a proactive adjective"

"Really?"

Ren watched as his Father nodded, sitting peacefully on the park bench, watching Ren attempt to reach the sky, swinging as high as he could. Just wondering out of curiosity, Ren turned his head around, so that he was facing the sky, and not his Father. "Father, does that mean I am one too?"

Hibari watched his son carefully, choosing his words wisely "You're not."
