After the battle, Kaoru returned to the alliance camp and explained the events that had transpired. With the use of the world reconstruction magic, the world map had drastically changed, causing chaos in various parts of the world. The deaths of the Daimyo caused by Kaoru and Haku added to the turmoil, affecting civilian conditions.
Fortunately, with the assistance of the Kage, the chaos was mitigated, and civilian uprisings were avoided. The shift in the geographical locations of countries also led to the emergence of new resources that each nation could utilize.
Kaoru suggested to the Kage that they establish their own nations, form alliances with other Kage, and explore the new world. Despite the chaos caused by Kaoru's jutsu, they acknowledged the potential benefits of the redistributed resources in developing their villages.
With the conclusion of the Fourth Great Ninja War, Kaoru and his friends' mission was completed. However, it should have ended sooner if not for Obito controlling Nagato and declaring war prematurely.
------
Currently, Kaoru and the others were in the underground base built by Kaoru and Shirou. They were planning their next steps after returning to their respective worlds.
"Shirou, can you contact me after you finish the Holy Grail War?"
"Hmm? Okay, but didn't you say that in my world, there's a super powerful entity that can detect the presence of alien beings from other worlds and eliminate the intruders instantly?"
"That's true, but I realized that if we enter using the features within the guild, that entity probably won't be able to do anything directly."
"As evidenced by your presence in the ninja world. If that entity had the power to oppose anyone behind the guild, you would have been eradicated from the start for going against its designed script."
"Moreover, for entities with immense power and long lifespans, boredom is their main enemy. So, as long as I don't disturb the Holy Grail War in your world, that entity might only be slightly interested and then forget about me."
Shirou, comforted by Kaoru's logical explanation, agreed to contact him after successfully completing the Holy Grail War.
Kaoru then turned to Chopper and instructed him to contact if the Straw Hat crew was in danger, especially if they reached the Sabaody Archipelago.
Next was Chifuyu, who presented her plan to Kaoru.
"Kaoru, what if after this, you visit my world and become a martial arts instructor at the IS academy?"
"Are you sure, Chifuyu?"
Chifuyu, well aware of Kaoru's brutality in training, was confident. Despite the harsh process, the results of Kaoru's training were satisfying.
"No problem, I'll handle the training menus for those kids, and you'll be the one to train them!"
Getting approval from Chifuyu, Kaoru smiled cunningly. He understood Chifuyu's intention in asking him to train the students at the IS academy.
"Oh! You're truly cruel, Chifuyu-san!"
"Ufufu! But not as cruel as you, Kaoru-kun!"
"Ohohoho!"
"Ufufufu!"
Their meeting room was now filled with wicked laughter as the two demon instructors planned the torture (training) that the IS academy students would face.
------
In the new Hokage's office.
"So, this time, you want to embark on a long-term mission?" Tsunade, currently serving as Hokage, asked Kaoru.
"Yes, as I've mentioned before, Kaguya is a member of the Otsutsuki clan, and other members will likely come here. So, I need to find another way to confront these Otsutsuki."
Tsunade massaged her forehead, contemplating Kaoru's warning to continue training and becoming stronger. It was easy to say, but she wasn't sure if their training would be enough to face the Otsutsuki.
Realizing the dilemma in Tsunade's mind, Kaoru suggested they could use the research he conducted with Orochimaru.
Hearing this, Tsunade, remembering Orochimaru as a brilliant ninja and the fact that Kaoru conducted research to strengthen the ninjas, felt a bit relieved.
"All right, if you have to go, I'll give you a long-term mission to find a way to defeat the Otsutsuki threatening the world of the shinobi!"
With that order, Kaoru turned into ice dust and left the Hokage's office.
On the other side, Tsunade, watching him leave, felt envious.
"Darn, elemental Bloodline Limits are truly cool and make others jealous!"
"You're absolutely right, Tsunade-sama!"
The two women in the room began to share their desires to have elemental Bloodline Limits as well.
-----
Kaoru, now reunited with other guild members, opened their guild system screen and selected the option to return to the guild hall.
In an instant, the four of them were enveloped in white light, and their bodies slowly disappeared from the ninja world.
Shortly after, they arrived at the guild hall, and this time, they were welcomed by Hibari.
"Welcome back! It seems the first mission was a great success!"
Hibari greeted them with her characteristic smile.
"Well! If only we didn't have to face enemies with continent-level strength and had to prevent the resurrection of a planet-level enemy, then this mission would have been perfect!"
"Ehhhh? Continent-level? Planet-level?" Hibari, hearing this, was shocked and immediately checked the mission records to see what had actually happened.
The more Hibari checked, the paler her face became. She didn't expect that one of the high-level entities would interfere in their first urgent quest.
Although that entity also rewarded them for their hard work, Hibari was afraid that the next missions would involve the interference of high-level entities.
Without delay, Hibari contacted the guild's creator, and fortunately, she received an answer that relieved her.
Hibari closed her message screen and informed Kaoru and the others about what had happened.
"Kaoru-sama, I apologize for not realizing this earlier. One of the high-level entities secretly altered the storyline on a massive scale, causing an absurd butterfly effect. They claimed it was a test for Kaoru-sama and the others."
"In addition, they're satisfied with the outcome of this issue, they also promised to not make any more interference at least until you complete five urgent quests, and for this trouble, Kaoru-sama and the others are entitled to a reward, which is undoubtedly much more valuable than the reward for completing urgent quest!"
After explaining this, the guild members felt a bit relieved. At least, they wouldn't have to fight against a god when they had just arrived at the quest location.
Kaoru immediately looked at his rewards:
[Congratulations! You got "one million guild points"]
[Congratulations! You got "Perfect Beauty" skill]
[Congratulations! You got "Body Cleansing Pill"]
The one million points needed no explanation, and as for the body-cleansing pill, Kaoru's guess was correct; it came from the cultivation world.
However, Kaoru couldn't help but frown when he looked at the skill he obtained.
[Perfect Beauty: Your beauty will increase to perfection, and now everyone will perceive you as an incredibly beautiful woman!
Effect: Gives a good impression to everyone meeting you for the first time, increases affection values for everyone who knows the owner of this skill, and makes it easier to build relationships with everyone.]
Reading the explanation of the skill, Kaoru wanted to flip a table. He didn't want to be called arrogant, but he was aware that his face was already too handsome, even to a beautiful level. Yet, with this skill, he felt that his backdoor was in danger.
Not wanting to dwell on it, Kaoru quickly opened the reward box, and when he did, he made a puzzled expression. Inside was only a gemstone that he didn't recognize.
The stone was black with golden gleams and a pattern resembling stars sprinkled across it, and Kaoru knew for sure it was an extremely rare and valuable item. He might not know about this particular black stone, but it was undoubtedly an extraordinary and precious object, especially with the starry pattern that seemed like a galaxy trapped in a stone.
Kaoru was uncertain whether to make a necklace from the stone or not, and upon closer inspection, he found a letter carefully placed beneath the stone.
Without fear or caution, Kaoru opened the letter, and it contained the following words:
'Pachi! Pachi! Pachi!'
'Congratulations on successfully completing the first game. As a reward, I give you this core. You should know that getting this core from W.O.H is extremely difficult. She's very stingy, unlike me, who is always generous and humble!'
'As an additional note, I'll be waiting until you can play at my level, so don't try to die, okay?'
'Warm regards from your loyal supporter, F.A.A'
After reading it, the letter suddenly disintegrated into dust.
Kaoru could guess the two names mentioned in the letter. This time, he realized where the stone came from and what power it contained. The worst part was that he understood both entities had a little twist in their heads and souls.
And, of course, the sender of the letter was the person he feared the most. It was impossible to escape from a crazy woman like her. With a heavy heart, Kaoru had to remain vigilant to avoid being detonated with his world just because that woman got bored.
Kaoru quickly pushed away thoughts of those crazy individuals and looked towards his friends.
"So, guys, what did you get?"
