c5: Melancholy Tsunade, Chat Group Shocked
But since the mission was posted by Tsunade, and he had personally come to her world, Karl felt that he should at least say something before leaving.
After speaking, Karl prepared to leave.
However, Tsunade set aside the wounded person in front of her and quickly ran toward him.
She bowed deeply, "Karl-kun, thank you for saving Nawaki!"
"What?"
Karl was stunned, looking at Tsunade with clear surprise in his eyes.
Logically speaking, at this point in time, Tsunade shouldn't know him at all.
Perhaps the Tsunade of this timeline hadn't even joined the Chat Group yet?
After all, from his perspective, she had joined at the same time as him.
But now… how did she know everything?
He looked at her and asked slowly, "You… recognize me?"
Tsunade nodded earnestly, her expression filled with gratitude.
"Of course. Karl is from the Chat Group and saved my brother."
Karl's brows furrowed slightly.
"How do you remember these things?"
"Huh?"
This time, Tsunade was the one left confused by Karl's question.
"Isn't… isn't this the mission I posted in the Chat Group? And then you came here?"
Karl looked at Tsunade for a moment.
Then suddenly, a faint smile appeared on his face.
"Mm, that's true."
Under normal circumstances, when someone travels through time and changes the past, only the traveler retains memories of the original timeline.
This was similar to certain events in DC Comics when The Flash altered timelines, creating paradoxes where only he remembered the erased reality.
But now…
Tsunade remembered as well.
Karl didn't fully understand why.
The only reasonable explanation was the Chat Group itself, a higher-dimensional existence that connected multiple universes, perhaps transcending even the laws of time and causality.
After all, even in Marvel, tampering with time such as using the Time Stone often created branching timelines rather than rewriting memory directly.
Yet here, something different had occurred.
At this moment, Tsunade looked at Karl with shining eyes.
"I didn't expect that you, Karl, could really resurrect Nawaki."
"And you didn't use any talismans or rituals at all… but actually used time travel!"
Her voice carried disbelief and awe.
This was something completely beyond the scope of ninjutsu.
Time travel… actually existed.
In any case, Tsunade found it hard to believe.
From her perspective, everything had happened in an instant.
Karl had just appeared in front of her, casually knocked away Jiraiya, and then suddenly disappeared.
The next moment her surroundings changed.
When she came back to her senses, she realized she was standing in a place she recognized.
Looking around carefully, she discovered this was the exact location she had been in a few hours earlier.
Even the sunlight, the atmosphere, the arrangement of people… everything matched.
Checking the time confirmed it.
It had indeed gone back several hours.
At the same time, she saw the Chat Group notification that Karl had completed the mission.
Which meant Karl had not only saved Nawaki…
He had reversed time itself.
In Tsunade's understanding, it even felt like Karl had brought her along through time, though in reality it was the timeline itself that had been rewritten.
Still, that didn't change one fact.
Karl was an existence that could freely manipulate time and space.
This kind of power…
Even among gods was rare.
Comparable perhaps only to beings like Superman in certain Silver Age depictions, or cosmic entities in Marvel capable of rewriting reality.
"Calm down, calm down," Karl said with a faint smile, facing the excited Tsunade.
Although this was also his first time truly using time travel in practice, he remained far more composed.
At this moment, the surrounding Konoha ninja began to notice the situation.
The ninja who had just been treated by Tsunade had already spread the news.
Soon, several ninja gathered nearby, all staring at Karl with vigilant expressions.
After all, his clothing and demeanor were completely different from theirs.
And during wartime, any unknown individual was a potential threat.
"Tsunade, who is this?"
Jiraiya approached slowly, lowering his voice as he spoke.
Tsunade glanced at Jiraiya, then turned to Karl.
A gentle and confident smile appeared on her face.
"This is Karl-kun, my friend."
"He is a very reliable person. Not an enemy.don't worry."
"Mm, that's right."
Seeing Tsunade's trust, Karl nodded slightly.
This trip to the ninja world had not been in vain.
Not only had he tested his abilities such as time reversal and high-speed movement but he had also completed his first Chat Group mission.
On the side, Jiraiya looked at the two smiling at each other and couldn't help but feel a trace of bitterness in his heart.
However, Tsunade's attitude was firm, and he didn't act rashly.
Karl then looked at Tsunade and said calmly,
"I've finished the mission. I'm leaving now."
Unexpectedly, Tsunade suddenly reached out and grabbed his arm.
"No rush, no rush."
"You saved my Nawaki, and I haven't properly thanked you yet."
"At least stay for a meal before you go."
Her tone was sincere and for the first time since arriving in this world,
Karl hesitated slightly.
Karl shook his head and politely declined, "No, I just ate not long ago."
"Ah?" Tsunade felt a trace of disappointment; she hadn't expected Karl to leave so soon.
"Then..."
"Remember to protect your brother well," Karl said calmly.
Subsequently, his figure vanished instantly.
Like a streak of light disappearing beyond perception—his speed and movement were comparable to the feats once displayed by Superman when crossing vast distances in an instant.
In the scene, only a faint voice remained,
"See you next time."
"Mm... see you next time."
Tsunade gazed at the place where Karl had been standing, murmuring softly.
For Karl, this mysterious, handsome, and overwhelmingly powerful existence, Tsunade naturally felt deep gratitude.
After all, he had saved Nawaki her only remaining family.
Deep in her heart, an indescribable feeling had quietly taken root.
Since he left so quickly, she couldn't help but feel reluctant.
But she knew there was nothing she could do.
All she could do…
Was wait for the next time they met.
...
Marvel Universe.
Karl's figure suddenly appeared in outer space.
Behind him floated the blue planet Earth, while in front of him burned a massive star, the Sun that continued to fuel his Kryptonian-like abilities.
This was the same universe where organizations like S.H.I.E.L.D. monitored extraterrestrial threats, and heroes such as Iron Man and Thor protected the world from cosmic dangers.
"Mm, I've moved around a bit… now it's time to get some good rest."
Looking at the Sun, Karl's figure flickered.
In an instant, he crossed the vacuum of space and returned to his apartment in New York.
While taking a shower, he suddenly sensed something.
His consciousness entered the Chat Group once more.
Just after entering, he noticed 99+ unread messages.
After a quick glance, he realized they were all discussions about the mission he had just completed.
The latest message came from Tsunade.
————
Senju Princess: Karl-kun, have you returned to your own world?
Senju Princess: Your kindness, I will remember forever. If you need anything in the future, you can find me @God of the Human Realm
What Should I Do If My Little Sister is a Middle Schooler??: Anything? Wow, that's really something...
Tenblade King: Shocked.jpg
Great Wall Guard Commander: What are you all thinking? Am I the only one curious about how the God of the Human Realm completed the mission?
Great Wall Guard Commander: Also, Karl... is this the name of the God of the Human Realm? @God of the Human Realm
Tenblade King: Curious +1
What Should I Do If My Little Sister is a Middle Schooler??: Curious +2!
What Should I Do If My Little Sister is a Middle Schooler??: I also want to know how Karl completed the resurrection mission! @Senju Princess @God of the Human Realm
Senju Princess: Karl-kun doesn't seem to be here, so I'll explain. It's like this...
Tsunade began recounting everything that had happened.
She described Karl's sudden arrival, his overwhelming presence, and how he effortlessly knocked away Jiraiya.
However, since the others were unfamiliar with Jiraiya's strength, they didn't fully grasp how shocking that feat actually was.
But when Tsunade described Karl flying away, reversing time, saving Nawaki, and even altering the past…
The entire Chat Group exploded.
Messages flooded in rapidly, almost faster than they could be read.
Great Wall Guard Commander: Really?
Great Wall Guard Commander: Resurrecting someone is one thing, but using time travel? Are you sure you're not joking?
Tenblade King: This… is indeed difficult to believe. Even divine beings or angelic entities cannot easily interfere with time like this.
Senju Princess: I was also shocked, but this is all true. I saw it with my own eyes.
What Should I Do If My Little Sister is a Middle Schooler??: Alright… as expected of a Chat Group that connects different worlds, there really are incredible experts here.
Great Wall Guard Commander: Alright, since the mission has already been completed, even if it's hard to believe… it must be true.
Great Wall Guard Commander: Looks like we now have a truly powerful member in the Chat Group—Karl.
At this moment, even across different worlds, all the members reached the same conclusion.
The so-called "God of the Human Realm"
Karl
Was an existence on a completely different level.
Someone who could casually accomplish feats that even cosmic beings in worlds like Marvel, those who wield artifacts such as the Infinity Stones would treat with extreme caution.
And for Karl himself…
This was only the beginning.
