An Eternal King for the Throne of Heroes

By Try Another Time

With Eero.

Eero and his small group walked through the snow in search of supplies. It was a stressful task but necessary at least for a few days. Suddenly Sella stopped.

"Sella?" Eero asked after he saw her stop.

"Something is happening back in the base. Something or someone is moving from one place to another within the property." Sella explained after feeling how a strange presence was moving around her threads.

"Sella, Leysritt, go back right now. Although I trusted the others, I won't treat this as an easy mission. If it is an enemy, eliminate it right away and if you can't, escape with everyone and come to me. Got it? " Eero asked for a confirmation.

Both nodded before leaving the fishes and jumping away.

"Don't you want me to go with them?" I ask Altera.

"No, but just in case I want you to be ready. At the first sign, you see them coming with the group, get ready to activate your noble phantasm. If it's an enemy, we'll wipe it from the map." Eero said.

Altera understood why his serious attitude. Eero was someone who showed complete coldness to the enemy especially if it showed intentions of harming any member of his "family." Altera knew where this way of thinking came from since she acted like this under similar conditions. "You'll do everything to protect us. It's always been that way." She thought before helping him take the fishes that Sella and Leysritt had left behind.

Back on the property.

Tamamo moved quickly from place to place while shouting the names of the other girls present on the property. Within seconds, the other girls had met Tamamo.

"What's going on?" Nero asked.

"Something or someone crossed the barrier. I don't know what it is or where it is, but there's an intruder." Tamamo explained as she stretched her tails. "Take positions. Nero, Mashu, form a circle with me. Illya, Sakura, Miyu, inside the circle keep your eyes open and shoot when you get the chance."

They all nodded. Mashu extended her floating shields alongside Tamamo's mirrors around them while Sakura summoned her bow which was somewhat worn out. While the others did their preparations, Illya and Miyu were ready to fire their spells if needed.

"Are you sure about this, Tamamo-san?" Mashu asked.

"I am. My barrier was set to prevent any intruders from entering. I know the smell and the mana running all over the body of our group members. No one could come in without alerting me and breaking the barrier. And this intruder has entered without breaking it which makes me feel alarmed. I don't know anything capable of doing that." Tamamo explained.

"What about Abi?" Miyu asked while thinking of her servant's portals.

"Abi would break the barrier with her portals if I prevented her entrance. This intruder came in without doing it, which tells me it's not someone normal." Tamamo said while watching every place in front of her.

"Then what can be able to do something like that?" Sakura asked. The young girl prepared her bow with an arrow while searching for any sign of the potential enemy.

"I don't know," Tamamo said.

"Do you think it might be any of those guys?" Illya asked.

"The probability is not zero. We don't know what other things they can have under their sleeves." Nero suggested. "Let's go out into the garden, I need more space to be able to wield my sword effectively."

"All right. Don't break formation." Tamamo ordered. "Where the hell can it be?" She wondered as she searched for any sign that would tell her where it was this supposed enemy. "I wish I hadn't let Sella go with them."

"It's too late for that, though if her threads are still connected to her, she will have noticed what is happening," Illya said as she put a hand on her chest. "Arrive on time." The little girl as she thought about her servants.

All of them proceeded cautiously until they reached the garden. Once there, they had to take care of many more places, but it would be easier for them to move and fight if necessary.

"Open your eyes wide," Mashu said. Her helmet was back on.

They all looked around until Sakura with her slightly more sensitive vision notices a slight flash of light disappearing at an inhuman speed on the ceiling. But she wasn't the only one, Mashu, Nero, and Tamamo attacked the same place after feeling the presence.

"I saw it. Flash of light on the ceiling. That speed is not human." Sakura said.

"Did you notice the appearance?" Nero asked.

"It was too fast," Sakura replied.

"How or what the hell are you?" Tamamo asked. "If you are the enemy show up and face us."

Everyone waited for some response, but no one answered.

"It was to be expected," Nero said.

"Put your weapons away." Said a voice.

Everyone looked for the source of that voice, but it wasn't anywhere.

"Show yourself!" Mashu demanded. She didn't like how someone or something was playing with them.

"As you wish, although it won't help you at all." Explained the voice before appearing right in front of Tamamo.

Tamamo saw the sphere of light. She showed no hesitation and covered the rest with a sphere made of her tails before attacking the sphere with multiple elemental attacks thrown by her mirrors. A smokescreen formed before her.

"Tamamo!" Nero exclaimed. She didn't expect to be covered by such a defense method.

'I'm fine but I couldn't afford to trust whatever that thing was." Tamamo said. She had already learned to distrust many things, but above all to put the protection of others before her own.

"Are you done?" The voice said. The smokescreen cleared up before showing the sphere intact.

"How?" Tamamo said. She didn't expect that all her attacks to fail at such a close distance.

"Tamamo no Mae, no let's use your real name, Amaterasu. I have come here to be heard no to fight." Said the sphere.

Tamamo felt her anger increase. Only her husband had the right to call her that and only the adults in her group could have known about her past. "Who the hell are you?" Tamamo yell. She was ready to attack once more. Her tails moved aside thus allowing the others to see what was happening.

"Tamamo, calm down," Nero said as she moves to Tamamo right side with Mashu taking the left. The younger ones stood behind the adults still wary of the situation.

"Start talking," Mashu said still sounded alert. She had learned to distrust any unknown being under any situation unless her "Senpai" said otherwise.

"I will present myself properly, I am the unconsciousness of humanity, Alaya. The cause behind the continuation of the humanity of this world. Under normal conditions, I would not manifest myself before you, but time warrants extreme actions. I know that all of you except the little one who goes by the name of Miyu does not belong to this world. Under other conditions, I would ask all of you to leave this world or be ready to suffer the consequences, but I can deduce that all of you can help us. I need you to take Miyu to Fuyuki's High School." Alaya said.

"... You've got to be kidding me." Tamamo said. Now everything connected. Only an existence like Alaya is capable of such actions. Tamamo was proud of her abilities, but even she knew when her powers were ineffective against things such as this.

"Alaya?" Sakura asked after seeing the sphere. She turned to look at the other two young girls who shook their heads.

"Girls I hope you remember this moment for the rest of your lives. We are in front of the personification of existence behind the creation of miracles such as the Maiden of Orleans, Joan of Arc." Nero said. This was something she didn't expect, Alaya wasn't a force that acted so directly. In all her years it had never shown up in front of Hakuno or the servants of the moon cell. Yet they were sure it was watching everything that was going on around them.

"Wait a minute, why do you need Miyu?" Mashu asked. She admitted to being astonished by this thing, but that did not take away from the fact that this existence had directly asked for Miyu to be taken to a place without knowing anything.

"Gaia and I are forces that work for different objectives. Gaia focuses on the world and its creature's survival while I focus on the survival of humanity for as long as possible. Possibly in your world, the same forces continue to work separately, but in this world that is not the case. We're both working together, and we need Miyu to save this world." Alaya explained.

"Wait, do you know why the world is ending?" Miyu asked.

"Everything was caused by Darius Ainsworth and Pandora. We look forward to your presence tonight." Alaya said before it started to banish.

"Wait, you can't say something like that and just leave," Ilya screamed at the sphere.

"Tonight, bring her and everything will be unveiled." This was the last thing the sphere said before leaving the group with more questions than before.

Miyu didn't know what to think at the time.

Later.

Eero and Altera came back carrying as many supplies as they could. Before they even entered through the barrier, they saw how Leysritt and Sella surveilled the area from the roof.

"Looks like they're all here," Eero said. He felt that all his servants were inside the property. "Sella, Leysritt!" He screamed at them which gained their attention.

They both came down and approached them.

"Tell me everything that happened," Eero said.

They both looked at each other before starting to talk.

"It was not an enemy, but something even stranger. Alaya appeared before the group and asked that Miyu be taken to a location tonight." Sella said.

"Did it say anything else?" Eero asked. He was surprised at such an appearance, but he cared more about why something like Alaya had appeared before them.

"Mashu will be able to explain everything in more detail," Sella said.

"Well, let's go in and discuss this," Eero said while Altera was very curious about this unexpected meeting.

With no time to waste the four of them entered and went straight to the living room of the house. Once there they saw how everyone, including Abigail, were silent and waiting for him. Sella and Leysritt took the supplies and headed to the kitchen while Eero took his seat alongside Altera.

"Mashu, do you want to start?" Eero asked.

Mashu nodded and began to speak. "This afternoon, as almost everyone knows, we were visited by Alaya, the force behind the continuation of humanity in this world. Normally based on the knowledge we possess this force doesn't present itself before almost anyone, but for some reason, it did before us. Alaya explained that it is working with Gaia to save this world, but for some reason, it said that they need Miyu. Alaya also said that whatever is happening in this world is because of someone named Darius Ainsworth and Pandora. About Darius Ainsworth, we can only infer that he is part of the family looking for Miyu, but about Pandora, we know much more." Mashu explained.

"Darius Ainsworth? Mashu please continue." Eero said as he thought about what connection there might be between the Ainsworths and Pandora.

"Pandora in the legends of our world is the person created by the gods and put in charge of pandora's box. Created by the gods, this box contains the worst of the world and by being open, its contents will affect the world in the worst ways possible. Illness, chaos, among other things, are contained within the box. Now there's something I discovered in this book about Greek history and mythology. What do we know about Pandora in our worlds?" Mashu asked.

"The box was opened by Pandora and the world suffered for it," Altera said. She remembered her time as Attila the Hun and her duel against Ares.

"Exactly. That has always happened in my original world, the world we call home and in your world." Mashu said as she pointed to Altera, Nero, and Tamamo who nodded. "Miyu in the case of your world, according to what is in this book, there is no legend that the box was opened."

"How can that be possible?" Altera asked. "It was something that had to happen sooner or later before the age of the gods ended. It's something necessary for the world."

"I know, but in this world that doesn't seem to be the case. In the legend of this world, Pandora never opened the box or nor anyone else. It was left close and forgotten by the rest of the world." Mashu explained.

"So, does that mean the world is running out of time because the box wasn't opened?" Illya asked.

"I'm not sure, but if it is because of this small change why wait until now to open it. The box had to be opened during the era of the gods and not after. There were heroes like Heracles and other things capable of facing everything inside the box which could be the insurance that would prevent the extinction of humanity. This era wouldn't be able to do it, much less in this state." Mashu explained. "My theory is that this world didn't need the box, or something stopped it from being opened."

"Then that cube we saw when we arrived, is that the box?" Sakura asked.

"It may be. But who brought it here? It was created in Greece and only Pandora could move it according to legend." Tamamo wondered.

"There is only one possibility, Pandora is still alive," Eero said.

"But she was human." Nero object.

"Nero she was created by the gods just like the box. There is a high chance they put a curse on her to prevent her death until her mission was accomplished." Altera said while sounding annoyed. "I should have hit Ares even more." Altera thought after remembering how much she hated the gods of that pantheon.

"Altera, relax. No one wants you to think about them." Nero said, knowing very well how bad her companion relationship with that pantheon was. "Just think of nice things." She continues trying to calm her down and prevent a catastrophe.

"Then the reason they are looking for Miyu is to open the box?" Illya asked.

"That's a possibility. But what should matter to us right now is what is the reason behind Alaya and Gaia needing Miyu." Tamamo said as she looked at the young girl who could only hear the argument.

Standing by her side, Abigail grabbed her hands trying to comfort the girl.

"Eer- No master, what do you plan to do?" Abigail asked with a more serious tone.

"It's an object of the age of the gods which is quite dangerous. Destroying the box is something I don't want to do without the assurance that the contents will be destroyed alongside it. Also, there is a possibility that it cannot be destroyed. Perhaps only eliminating all the Ainswoths would be the easiest option? But we don't know the full extent of their forces either. Abigail, did you find anything during your mission?" Eero asked. He was considering every possibility especially with the little time they had left.

"Near the "Box" there is an area protected by a barrier. Some of my snakes entered with little resistance and as far as I could learn from them, it is a separate property from the rest of the world. It doesn't seem to be being affected by the weather or what's happening in the rest of the world. "Abigail explained.

"We have where they are... Miyu?" Eero said.

Miyu stared at him.

"Alaya and Gaia are not forces I would trust myself. I would decide to go for the Ainsworths directly and not paying attention to any of those forces because the box doesn't look like it's going to be opened without you. If we eliminate the Ainsworths, we can leave this place. The box is not our priority right now." Eero admitted, but he wanted to see what Miyu would decide.

"But If that box stays there, what about the rest of the world?" Miyu asked.

"The box won't open. They haven't done it in over 1000 years, and without you, I don't think they can do it. If we eliminate Julian and his followers, no one will come looking for you or use you. I don't know if the world would be saved by that, but your safety is something that matters most to me right now." Eero continues.

Miyu was silent. She didn't want to be used, but only saving herself without knowing what would happen to the rest of the world was something she didn't want. Maybe listening to what Alaya wanted would be a good option? "I want to know what Alaya and Gaia want from me. I can't decide without knowing if there's a better option. This is my homeworld and although nothing is left to me in this place, I don't want to turn my back on it without trying at least once." Miyu said.

Everyone else present was silent. The adults understood the girl's desire so they couldn't judge her for thinking this way while Illya and Sakura could only be astonished at such maturity.

"If you want to do it, we will follow you, but if I feel it's something that will put you in danger, I won't hesitate to take drastic action. Abigail, you know what I mean?" Eero asked.

"I understand. Miyu, I will not separate myself from you for the rest of our stay in this world." Abigail said. She knew what she had to do to ensure Miyu's survival if things took a dangerous course.

"Thank you," Miyu said. She felt that Eero was taking her seriously and not just ignoring her for being just a child.

"Well, if there are no other things to discuss, let's eat and get ready to go to the high school in this world," Eero said.

"Eero?" Sakura said.

"What's going on?" Eero replied.

"My bow," Sakura said as she summoned it. "I don't think it's going to survive much longer without some repairs."

"I should have imagined," Eero said as he watched carefully. Some cracks had appeared. It was a bow that he had created for her to practice with normal arrows and the elemental arrows made by magic were too much for the bow. "Come with me and Illya you will come with us as well."

"Why me?" Illya said.

"Do you think you can keep fighting without a mana transfer?" Eero asked.

"Hey? But I'm fine." Illya said. She didn't like where this was going.

"Leysritt grabbed your lady and follow us," Eero said when he stood up.

Without hesitation, Leysritt left the kitchen and went to grabbed Illya before following Eero to Sakura.

"Let go of me!" Illya exclaimed.

The others could only laugh at the tantrums of Kiritsugu's daughter.

"Stop yelling," Eero said as they moved into another room a little secluded from the living room. Once inside they all took their seats, although Leysritt kept her grip on Illya.

"Leysritt!" Illya yelled.

"Turn her around and show me her back," Eero ordered. "We have already done this several times for two years, so stop acting this way. You need to have as much mana as possible."

"I don't like you doing it," Illya said. There were only two people who could pass mana for her survival, one was Sakura and the other was Eero. She normally received a transfer every two weeks, but if she was practicing magic for long periods, she required an immediate transfer. Kiritsugu had taught her the need to use as little mana as possible in any situation because if she ran out of reserves she would be in serious trouble.

"Sakura?" Eero asked.

Sakura shook her head. "It's okay for you to do it."

"There you have it. Just relax and let me get this over with." Eero said as he placed his hand on his adopted sister's back.

In seconds, Illya's magical circuits shone alongside Eero's. The mana inside Eero ran in a continuous flow to Illya which blushed as Eero's mana warmed her up. While Sakura's mana felt more like a cold flow of water yet when Eero's entered her body it always caused her body to burn from within. This feeling was something Illya disliked because it wasn't something, she wanted to feel with him.

It was wrong, but once it started, she couldn't do anything but accept him.

The transfer continued for several minutes until Eero felt that Illya couldn't hold on any more mana. While this was happening Illya felt as if her body was melting. She could feel her body overflowing with energy.

When Eero removed his hand Illya felt she couldn't even move or stand up. Leysritt held her in place after watching this event several times over the past two years.

"See it wasn't that hard?" Eero said. Before directing his attention to Sakura's bow.

"... You idiot." Illya replied with difficulty.

"Well let's see what we can do," Eero said as he used his ability to feel every detail of the bow structure. "I think I should have used a stronger composition for this work. When we get Tristan's bow, I'll make sure that the material can withstand your attacks."

"Wouldn't it be easier if you created a copy of that bow for me?" Sakura asked.

"I could do it, but it wouldn't be the same. Failnaught holds power and was used by one of the greatest archers in the history of the world. I want you to have it in your hands so you can feel the experiences the bow has endured. I want you to practice and one day make it yours and not just the weapon that you were given. I'm confident that one day you'll be able to use it as well or better than him, maybe even better than me with the copy." Eero admitted.

"..." Sakura could only hear and feel how much hope he had in her. Since she started this training regimen with him, there was not a single time in which he showed disappointment in her performance. Even though she sometimes felt that she was unable to achieve his expectations, he always assured her that she could do it and that she just needed to keep trying. He was the person that made her improved the most alongside Leonne. He was someone who she wanted to continue to follow for as long as he would allow it. "I will not fail you and I will always try to be of some use to you." Sakura thought.

That said, Eero began to repair the bow. He easily began to reposition each atom and bow component in a new configuration capable of withstanding Sakura's shots.

It would be a quick job, but he expected it to serve her well for the rest of this situation.

After a quiet dinner.

The group exited a portal right in front of the school that Mashu remembered well back at home. The only difference is that this seemed to have been a battlefield of some sort. There were several holes in the building, slash marks and it even seemed to be close to collapsing.

"That doesn't seem to be weather damage," Sakura said.

"Someone fought in this place. Sella spread out your threads. Look for any presence." Eero ordered.

Without wasting time, Sella pulled out as many threads as she could, letting them spread throughout the property. In seconds, the place was under her control. She looks for any presence in the place until she felt two.

"In the back, on the second floor, there are two. One of them is Alaya, the other one is strange. It doesn't seem to be human." Sella said.

"Not human? This is getting weirder." Tamamo said.

"Abigail take us to them," Miyu said. She didn't want to waste any more time.

Without hesitation, Abigail opened a portal right into the room where Alaya was alongside someone in chains. Everyone saw them and pass through the portal. They saw Alaya and chained female figure who remained silent. Her gaze was fixed on Miyu, which caused a chill to run through Miyu's back.

"Alaya," Eero said when he saw the sphere of light.

"Shirou Emiya? No, you look different. Your soul is too. Who or what are you? " Alaya asked.

"That's not necessary. Start talking. What is the connection between the Ainsworths, Pandora and what is happening to this world?" Eero asked. He was sure that Alaya had all the answers behind what was going on.

"... During the age of the gods, Gaia and I saw the creation of Pandora and her box. The Greek gods in this world created it as a way to force humans to need them. Alaya and I decided the box shouldn't be opened. We devised a method in which to snatch Pandora's ability to open the box." Alaya said.

"What did you two do?" Mashu asked.

"An army of humans was influenced by us and guided to the place where Pandora waited for the signal to open the box. That army attacked Pandora putting their lives at risk until they gave a certain magus a chance to use a magical circle, we created to steal Pandora's memories. The key to opening the box was always on her mind. That magus stole Pandora's memories related to how to open the box and committed suicide to make sure she never got them back." Alaya continues.

"You two were the cause of the box not being opened. Why doing that?" Nero asked.

"Humanity and the world didn't need to suffer because of the gods. The contents of the box would only cause destruction. Just opening the box wouldn't prevent the end of the age of the gods. We did it to make sure the world didn't suffer because of the contents of the box. It was all for the greater good. Killing Pandora wouldn't be possible, but her memories were the easiest way to prevent the box from being opened, although we never expected the gods to decide not to order her to open it. Pandora continued to wait for the signal or the return of her creators for centuries, but this never happened. Gaia and I were sure we'd never have to worry about the box, so we didn't pay it attention. All that changed the day Darius Ainsworth found Pandora. " Alaya said.

"Darius Ainsworth? Was he an ancestor of Julian Ainsworth?" Eero asked.

"He was the founder of the Ainsworth family. Darius was a magus who lived more than 1000 years ago with great skill and attitude for magic. His greatest desire was to become a legend. Someone capable of being engraved on the throne of heroes. But even with his skill, he felt that he had not achieved anything worthy of being remembered as someone who left a mark in human history. His quest for glory led him to Pandora." Alaya said.

"But the box has not been opened and no one can live for so long. His goal failed." Altera said.

"Darius knew he wouldn't live for so long so to make sure he would be able to open the box someday he decided to use his family to make sure of it. He created the closest magic to immortality in this world. Each of his descendants is a new anchor to keep his soul in this world. For more than a thousand years, Darius Ainsworth continued to research and look for ways to open the box. His quest led him to the creation of the war for the grail of this world." Alaya's words hit Miyu the most. The person who has caused her so much pain only did it to secure his legend. Not for the good of the world, but for his glory.

"All this for such a pathetic goal. Those who manage to reach the throne of heroes do not think about reaching it. Each of us lived a life following our ideals and desires not for our legend to reach the throne." Altera said. She was disliked the actions of Darius. Things like this were the ones that had driven her to eliminate entire civilizations.

"Alaya this doesn't explain why the world is ending or why you two need Miyu," Eero said still trying to stay calm.

"Gaia sees humans as a nuisance to the world. The fact that Darius continued his investigation nearly breaks our alliance. I proposed sending my counter guardians to eliminate Darius, but my proposal was denied. Gaia wants to eliminate the box. To make sure this happens, for centuries the energy of the planet and the energy I would use to empower counter guardians were redirected to the creation of a weapon capable of destroying the box and its contents. All the natural disasters that have occurred have been because of the planet's energy was being redirected to that weapon. This being by my side is that weapon, "the truth of the world." Alaya said.

"You can call me Tanaka." Said the weapon.

"All those disasters and destruction to create a weapon?" Miyu asked still sounding incredulous.

"The box and its contents must be destroyed. If the box opens, it all ends for the remaining humanity and the world. The world will not be able to endure the contents of the box in this state, Tanaka's creation has left Gaia weakened. Humans who are touched by the contents of the box will cease to be human and without humans, I do not exist." Alaya explained. "The deal behind this plan was that both forces would work to create the weapon and a human would use it to bring the end of this nightmare. Without a box, Darius will not be able to reach his goal."

"We understand that part well, but why must it be Miyu? There are other humans in the world." Abigail said. It bothered her that they wanted to use Miyu.

"There are no humans in Japan anymore. In the last five months, humans have left Japan and other places in search of a place to restart their lives. The world will recover, but that will take time and only the strong will be able to survive the next decades until the world recovers." Alaya said.

"That... can't be true," Miyu said.

Alaya said nothing and only showed images from different parts of the world in front of them. Tokyo was an ice city like other places around the globe such as Hong Kong, New York, Madrid, and even Egypt.

"In five months, things have gotten worse than what you think. And if you let the box and Darius exist, this will never end. There's only one way, Miyu Emiya, you have to accept the weapon and sink it deep within the box." Alaya said.

"Don't even think about it. If you need someone to do it, I'll do it myself, but Miyu won't go into that place." Eero said by having Bahamut appear in front of her as a sign for Alaya to stay away from Miyu.

"Only she can do it. The weapon is only compatible with humans and none of you are. Each of you is an organism that goes against the natural order of things, servants, homunculus and a species unknown to me. None of you can use it." Alaya said.

"Just watch me do it," Eero said before moving at an inhuman speed and standing in front of Tanaka.

"Boy, you don't know what you're doing," Tanaka said sounding annoyed.

"I know very well what I do," Eero said before putting his hand on Tanaka's chest. Within seconds Eero's magical circuits shone as Tanaka was analyzed.

"You're playing with fire," Tanaka said. She felt how Eero was deciphering her secrets. Tanaka's chest began to shine, and several cracks appeared around Eero's hand. The cracks began to slowly expand as his arm seemed to begin to burn.

Eero felt an indescribable pain but did not stop.

"Eero stop!" Miyu said. She saw how his arm begins to be consumed.

Just as fast, Nero moved, and she cut Eero's arm off without hesitation when she saw the cracks were approaching his shoulder. "I don't know what the hell you are, but you're dangerous," Nero said while looking at Tanaka and helping Eero to stand.

"I warned you. I was created to destroy the box, its contents, and Darius Ainsworth. I'm the virus created at the center of this planet. Burning as hot as the center of the earth. A weapon with many shapes and a single purpose. I'm the truth of the world. The world that refuses to allow the opening of that box." Tanaka said. "That girl is the only one who can end this. Take me inside you and let's get this over with."

Miyu felt more afraid of Tanaka's words. She felt how the fate of the world seemed to fall into her hands and only hers.

"She won't. I saw it in there. That virus will not only destroy the box and content, but also its user. If someone accepts you inside of them, they'll surely die when it's all over. No human could survive that mission." Eero said as his arm was reconstructed from the ashes. "Alaya, you created this weapon to make sure no one uses it for anything else after the box is destroyed or I am wrong?"

"It was the only way. Tanaka must return to the place where it was created when is all over. It's not a toy for a human to do what he wants with it." Alaya admitted.

"Abigail. Open the portal, we're leaving." Eero said. "Don't even think about it." Bahamut disappeared.

Without objection from anyone, Abigail opened a portal and took Miyu's hand leading her into it.

"Miyu! We'll see each other again." Tanaka said with a smile.

Nobody said anything and they just left that place. They had all the pieces, but this discovery had forced them on a single path forward or so they thought.
