CHANGE OF PLANS

"Special conditions? What special conditions do you mean? And what would happen if someone met those special conditions?" Zabuza asked.

"The special condition I mean is when someone has more than one Kekkei Genkai. If a person has two Kekkei Genkai, they will not be able to live more than 25 years." Emiya answered which surprised everyone.

"Eh? How come?" Midoriya asked.

"My parents said that this was a curse and punishment for greedy people. As I have observed over the past 5 years, many people in this world also marry because they want to give birth to strong descendants or be able to have children who have quirks from both parents. An example is Todoroki Shoto-sama who has two different quirks. This is no different from the conditions in Kirigakure Village before."

"Thousands of years ago, families from different clans also wanted to have descendants who could inherit two Kekkei Genkai because they wanted to have power over other clans. So the practice of intermarrying between Kekkei Genkai clans is not uncommon. However, getting descendants to inherit two Kekkei Genkai is very difficult, so even though most clans do it, it doesn't mean their descendants will definitely have two Kekkei Genkai. There's definitely only one of them that's dominant."

"And even if they have descendants that have two Kekkei Genkai, they definitely won't be able to live more than 25 years. Many records record the lives of people who have two Kekkei Genkai and none of them are recorded as being able to live more than 25 years. They were all recorded as having had serious illnesses before their deaths. And one sign that their illness is getting worse is when the person experiences headaches that appear more frequently." Emiya said which made everyone silent.

"That's not possible."

"Haku-kun…"

"Don't you have a way to save Haku?" Iida asked.

"Even now, I'm still looking for a way. But, the easiest way is to remove one of the Kekkei Genkai from his body. I lived with my grandfather who was the former owner of two Kekkei Genkai, and now he is still living healthy at the age of 79." Emiya said which made everyone have hope.

"How?" Uraraka asked.

"My grandfather was a descendant of the Uchiha and Yuki clans, just like me. In the past, he had a special Kekkei Genkai for the Yuki Clan, the ability to manipulate water and ice elements and a special Kekkei Genkai for the Uchiha Clan, the Mangekyou Sharingan. In the past, he also had the same signs, experiencing excruciating headaches. He was able to live until now because he gouged his own eyes which were the Kekkei Genkai of the Uchiha Clan, that way, he was able to survive the curse." It was Emiya who surprised everyone again.

"That's really reckless." Yaoyorozu said.

"So, that's the only way that can save Haku?" Todoroki asked.

"No. It's not certain that Haku has two Kekkei Genkai like that. It could be that the headache was because he was tired from work. Right?" Mineta said.

"That's right. "It's not certain that Haku has two Kekkei Genkai." Kirishima said.

"Currently, we already know that Haku has a Kekkei Genkai, the ability to control water and ice." Todoroki said.

"Zabuza-san, does Yuki-kun have…." Before Midoriya had finished asking, he immediately stopped when he saw the expression on Zabuza's face which looked regretful, annoyed, resigned, panicked and afraid all in one.

"Zabuza-san, don't tell me that Haku has two Kekkei Genkai like that?" Aizawa asked which made everyone start to get goosebumps and fear.

"Haku… He also has the Mangekyou Sharingan." Zabuza said which shocked everyone.

"That's not possible. He never showed us." Jiro said.

"Haku and I have agreed not to say this to anyone else for his own good. Because we still have Orochimaru who is our enemy. He might want Haku's eyes if the public finds out about this." Zabuza said which made everyone silent.

"Actually, there is another way to avoid the curse." Emiya said which made everyone see a little hope for Haku's safety.

"Is it true? How?" Kaminari asked.

"How do you know that?" Todoroki asked.

"I know because I myself also have two different Kekkei Genkai." Emiya said.

"Is it true?!!"

"I am a descendant of the Yuki and Uzumaki Clans. I have both Kekkei Genkai of both clans. The ice elemental power of the Yuki Clan, and the chakra chains of the Uzumaki Clan. You may have all seen it during the Kyuubi's attack, what holds it back is called a chakra chain. And I am now 30 years old." Emiya said.

"How do you break your curse?" Sato asked.

"I didn't break the curse. I just prevented the curse from attacking me. I am a researcher and I have been researching this curse for 13 years because I want to live longer with my lover. And the result is that this curse cannot be removed unless a Kekkei Genkai uses the eyes as a vessel to activate the Kekkei Genkai."

"The results of my research show that a shinobi's body is made to accommodate only one Kekkei Genkai, no matter what clan the shinobi belongs to. Because Kekkei Genkai is a very strong ability, a shinobi is only resist to have one Kekkei Genkai. If there is a shinobi who has two strong Kekkei Genkai, then their body will not be able to withstand the strength of the Kekkei Genkai that burdens their body. If two Kekkei Genkai are used simultaneously, it will be very taxing on the user's body because it uses a lot of chakra for two different usage focuses. If the user continues to use two Kekkei Genkai simultaneously it can damage the user's body."

"Basically, the Yuki Clan's Kekkei Genkai is a weak Kekkei Genkai, but because Haku-sama has been training it since childhood, this makes his ice element Kekkei Genkai become a strong kekkei genkai rooted in his body. Then Uchiha's Kekkei Genkai, Mangekyou Sharingan is a very strong Kekkei Genkai. So, this condition is very dangerous for Haku-sama. I was able to live until now because I had rarely used my ice element abilities and my chakra chains. It's been 7 years since I last used my Kekkei Genkai. I also came to the conclusion that this curse only appears when someone uses two Kekkei Genkai simultaneously in close proximity. So far I've only used normal techniques and I haven't felt any headaches." Emiya said.

"Then, if Haku fights without using his Kekkei Genkai again, he can avoid the curse! That's the easy way!" Mineta said.

"You're right!" Kirishima said.

"You guys are stupid, aren't you? Didn't you hear what he said earlier? That person has been used to using his ice element Kekkei Genkai since childhood. It is impossible for someone to change their fighting style drastically in a short time. Habits are hard to change." Bakugo said.

"Will the curse still attack if Yuki-kun only uses one Kekkei Genkai?" Midoriya asked.

"Of course I thought about that too. And I also tried it with my own body as a bet after my two Kekkei Genkai awakened. The result is that I still have headaches, although they are not as severe as when I use both Kekkei Genkai at the same time or close to each other. So, in essence, using a Kekkei Genkai will only slow down the disease. The easiest way is to ask Haku-sama to stop fighting anymore." Emiya said which made everyone silent.

"Making Haku to stop fighting…"

"Then, if he wants to live a long life, that means he has to stop being a Hero or ask him to no longer use his Kekkei Genkai." Yaoyorozu.

"Or gouge out his own eyes so he can completely get rid of the curse." Bakugo said making everyone shiver.

"That's right." Emiya said.

"If that's the only way, we can't allow Haku to fight on the front lines during the war. If he couldn't use his full strength, then it would be better if he didn't participate at all. Looks like we have to report this to the commission so they can make a plan without Haku in it. Even though Haku has become a very great pro-hero, he still has the status of a student here. And as a school principal, I don't want any of my students to force themselves to fight when their lives are in danger. I also don't want any of my students to die again when they could have a good future. Zabuza-kun, is my decision acceptable?" Nezu asked.

"Yes, principal. He's worked hard before, now it's our turn, the adults, to finish what he started. I want Haku to live longer and enjoy the life he wants. I've had enough of seeing him battered from forcing himself again. This time, he must not oppose me again." Zabuza said seriously.

The next day, Nezu reported Haku's condition to the commission so they had to change their plans so that the war could still run well. At the same time, Zabuza and Haku had an argument in Haku's room. Everyone immediately knew that Haku was insisting on wanting to stay in the war later and Zabuza was also very insistent on Haku so that he just rest and not take part in the war.

In the end, Aizawa and Recovery Girl came to convince Haku that he must stay here and obey the decisions of the principal and other adults. Nezu's decision to leave Haku has also been heard by Hawks, Orca, Endeavor, and Edgeshot, they all also agree with Nezu's decision because they think that Haku's hard work over the last month has been very great and his performance has surpassed their performance so they allowing or participating in forcing Haku so that he does not participate in the war for his own safety. Even though they all know that a Hero's duty is to prioritize the safety of the people, they don't forget that Haku is still a student and very young. Not participating in the war later was a fitting reward for his very meritorious performance.

After hearing the decision from all of them, Haku finally gave up trying to force himself to take part in the upcoming fight. Even though many of his friends were sad to see Haku often gloomy and silent, they knew that this was for his own good, so Haku had to accept it even though his heart was against it.

=========================================================

Several days passed, and it was time for them to leave for the battlefield. In the morning, everyone was wearing their hero costumes in full. Many of class 1-A have upgrades on their costumes. Everyone has now gathered in front of the dormitory, including Haku's three wives and Zabuza.

"Will Yuki-kun be okay here alone?" Midoriya asked.

"He'll be with Eri and Recovery Girl, there are also some teachers staying with him, so he should be fine." Todoroki said. Then suddenly they saw Haku coming out of their dormitory in his white kimono.

"Yuki-kun." Midoriya said.

"Everyone. Please be careful." Haku said a little bitterly because he couldn't come with them.

"Unn… We will definitely come back safely." Iida said.

"Wait for us here and await our victory, Haku!!" Kirishima said.

"We will definitely win this battle you have prepared." Yaoyorozu said.

"We have been practicing for about a year. That training will not be in vain. We will come back and bring victory." Kaminari said.

"Trust us, Haku! We'll be fine there." Mineta said. Seeing all his friends who were confident made Haku's heart feel relieved.

'Their auras are already much stronger than when we first met. I just realized it now. All the dangerous enemies I could track down have been taken care of, the danger level should have been reduced a lot. They can definitely do it well.' Haku thought.

"I believe in you guys." Haku said with a smile. Then he turned to his three wives.

"Sasaki, Hanami, Masami..." Haku called, the three of them immediately approached Haku.

"Haku-sama…" Haku immediately kissed the three of them on their lips in turn and then hugged the three of them. His friends, who were not ready for Haku's bold treatment, immediately turned red, including Haku's three wives who were kissed on the lips for the first time. There is no visible lust, only sincere love and affection.

"Come back to me safely, you three." Haku said.

Haku's three wives immediately smiled brightly and said, "We will return to you, Haku-sama." said the three. Then finally Zabuza approached Haku. Haku's three wives stepped aside because they knew that Zabuza wanted to say goodbye to Haku too.

"Haku...".

"Ojisan…. I'm sorry that I was too stubborn yesterday. I know that you guys made that decision for my own good, but I stubbornly refused. I'm sorry if I've hurt your feelings, Ojisan." Haku said regretfully.

Zabuza looked closely at Haku's regretful face, then finally he sighed and patted Haku's head gently. "If you understand, then there is no problem. I'm also sorry for yelling at you too loudly yesterday." Zabuza said.

"Come back safely, Ojisan." Haku said.

"Yes. I will come back to you." Zabuza said then the two of them hugged.

After saying their farewells, everyone got on the bus to go to the battlefield. When their bus left, Haku waved with the teachers and Recovery Girl who came out shortly after Haku released his hug from Zabuza.

"Now, all we can do is pray that they will all be granted safety and victory." Recovery Girl said.

"Yes." Haku said as he watched the bus drive away from the dorm.
