Naruto: The Medical Shinobi

"From all the people in my universe, why me?" Ken asked, trying to appear calm despite the rising tide of trepidation within him.

"And for what purpose?" he continued.

"Amusement, Mr. William," Mr. End drawled, popping another iridescent bubble with a casual flick of his finger. "Entertainment in this endless expanse can be scarce. It's not all fun and games, creating universes and ending them. Sometimes, we need a bit of... spice."

"You see, comic relief is what gets the two of us going in this vastness of the void. Even the architects of existence can succumb to boredom," Mr. Beginning explained, his tone laced with a hint of dry humor.

Unimpressed with their reasoning, Ken sarcastically retorted, "So you yank a random soul out of existence to play Jester? It seems a tad excessive, wouldn't you say? How about a good book, or perhaps a subscription to the latest multiversal Netflix? I hear 'Keeping Up with the Kardashians' is quite popular across multiple dimensions. Or maybe you could try knitting? I hear it's very relaxing, even for cosmic entities."

Mr. End chuckled at his humorous response and remarked, "This kid is funny; wouldn't you agree, brother?"

The beings exchanged amused glances at Ken's remarks, their amusement resonating through the endless expanse they inhabit. Ken couldn't help but feel a twinge of unease at their apparent delight in his predicament.

"Oh, that wit is certainly entertaining," Mr. Beginning agreed with a nod. "But rest assured, Mr. William, this is no mere joke. We have grand designs in mind, and you play a pivotal role."

Mr. End said, "Yes, Dear Ken. Either that, or we can create our own entertainment, and no, you were not chosen at random. We chose you for a reason."

A chill ran down Ken's spine at those ominous words. He couldn't shake the feeling that he was a pawn in some cosmic game, the stakes of which he couldn't begin to fathom.

"What am I, the story or the wager?" Ken asked, his voice wavering slightly.

"Both, my dear Ken," Mr. End retorted with a mischievous glint in his eye.

Ken felt his head spin at the implications. "Both? How can I be both the story and the wager? That doesn't make any sense!"

Mr. Beginning's form pulsed gently. "In the grand tapestry of existence, Mr. William, you are but a thread. Yet, it is the interweaving of these threads that creates the most fascinating patterns."

Mr. Beginning seemed to sense his confusion and clarified, saying, "Mr. William, you see, we have decided to use you for comedic relief. We will drop you into a story whose resolution is predetermined, yet we hope for a different outcome; therefore, your role comes into play, and we will watch to see how things play out with you in the story."

Ken's scientific mind rebelled against the concept. "But if the resolution is predetermined, how can there be a different outcome? Doesn't that violate the laws of causality?"

Mr. End's laughter boomed through the void. "Oh, Ken. Your understanding of causality is but a drop in the ocean of true cosmic law. In the multiverse, every possibility exists simultaneously. We merely... nudge things along."

"Just another reincarnation tale," Ken said, his expression emotionless. On the inside, though, he was intrigued. The concept of reincarnation had always captivated him, and now he had the chance to actually experience it, albeit under strange and unsettling circumstances.

Mr. Beginning answered, "Yes, Mr. William. A typical reincarnation story, as you said." "Are you up for it?" he enquired, his voice carrying a note of challenge.

Ken pretended to think about it, wanting to avoid appearing too eager. He knew that Mr. Beginning and Mr. End were watching his every move, studying his reactions like a pair of cosmic scientists observing an experiment.

"You know," Ken said, trying to keep his voice steady, "in all the reincarnation stories I've read, there's always a catch. Some cosmic joke or twist of fate that the protagonist has to overcome. What's mine going to be?"

Mr. End's form darkened slightly, and when he spoke, his voice was like gravel grinding together. "Ah, that would be telling, wouldn't it? Where's the fun in knowing all the plot twists before the story begins?"

Mr. Beginning leaned forward, his voice low and steady, carrying the weight of omniscience. "We've been watching you, Ken. Every decision you made, every victory and setback, all painstakingly documented in the fabric of your existence."

"You were always different," Mr. Beginning continued, his tone a mixture of admiration and pity. "The brightest are often the most burdened, you see, and the most driven. You dedicated your life to finding cures for diseases that plague humanity."

Mr. End, a being whose presence radiated an air of quiet observation, chimed in. "Qualified in chemistry, botany, biotechnology, and genetics," he listed, his voice tinged with admiration, "you were widely regarded as the century's genius. You even provided your results to the world for free, refusing to profit off of the suffering of others."

"In the end, you had an awful accident," he began, his voice heavy with sympathy, "and were completely paralyzed. You then donated all of your fortune to orphanages and organs for the destitute before ultimately meeting the end. Pun intended."

Ken listened intently. Finally, after a long silence, he broke the tension and asked, his voice barely a whisper, "So you are giving me this chance because I lived a good life?"

"We are offering you this chance because of the change you brought to the world, and we hope you will bring similar changes to your next world," Mr. Beginning continued.

Ken felt a wave of emotion wash over him, threatening to overwhelm him. "I never knew. Thank you for telling me this," he said quietly, his eyes filling with tears.

"So, are you up for it?" Mr. End asked, his voice filled with anticipation. "Ready to trade in your lab coat for a hero's cape in another world?"

Feeling the weight of the decision before him, Ken inhaled deeply. Finally, with a broad smile on his face, he said, "I am in. Let's see what you have in store for me. Let's do it."

As the words left his lips, Ken felt a sudden shift in the air around him. The void seemed to pulse with energy, and he could feel the very fabric of reality bending around him. He was about to embark on a journey that would challenge everything he thought he knew about science, reality, and himself.
