Kreist smiled at that "Fantastic." Adonis was curious "But how will we find Atlantia?" The rabbit boy smiled "Leave that to me."

Hokuto sighed "Okay but we can't all go. If we all disappear especially Trickstar. Nito will find out right away. Better a small group go."

"Yuu-kun~*" Everyone freeze while Yuuki sighed "Izumi-kun..." The Knights idol smiled "I've heard it all~* I'll go too~*"

"HEH!" Makoto looked on in horror.

Izumi smiled "If you refuse I'll have to tell Nito." Kreist all eyes "Great..." Makoto sighed "Alright.... You can come." Mao looked on uncomfortably as another person emerged behind the Knights idol.

Yuuki looked on in amazement "Mackie." His twin smiled "I'll come too, you'll need help in case of a fight."

Chiaki sighed disappointed "I'd like to join but it would raise suspicion if I'm not there, I'm the leader of Ryuseitai. I can't leave my Kohais and Kanata without more."

Subaru looked disappointed before nodding "Be careful then Ukki." Kreist smiled "Tomorrow meet at a square I will mark you by phone message."

They all nodded as they parted ways each returning to their respective homes.

The next day.

The whole group was in the square. Kreist had said that in order not to arouse suspicion he had asked them not to pack anything as he had prepared several outfits and what was needed for the trip.

They all followed the map leading them to the back of the Royal Academy where Kreist was waiting for them "Finally, it was time. I managed to fool Nito by saying I have business at home Ederigh. We can't waste any more time." He let them in and they entered a warehouse as Kreist touched the floor opening a slab where he revealed a fingerprint reader which he put his hand on.

BWOOOOMMM

In front of them the floor opened revealing a passageway descending as they all immediately entered before it closed behind them. They all continued down as light bulbs illuminated the passageway.

Izumi was curious "What this place?" Kreist smiled "My the secret lab~*" They all looked curious as they saw at the end the exit of the passageway being greeted by two academy scholars who nodded to Kreist.

Everyone looked on in amazement as they walked down the stairs leading to a dock. The group looked around as Izumi looked on in disbelief "Well?"

At that instant they heard another pair of footsteps as a boy appeared behind Kreist "Arr! Sailor~* So these are our first passengers, Kreist?"

"Greetings, Ensemble Square boys! I am Captain Nathan Kor. Captain of the Oceania." Everyone introduced themselves as Mackie looked around. "But I don't see any transports."

"Fufufufufu~*" Kreist crossed his arms as he smiled "Because this vessel also travels underwater." Everyone understood what he meant "I present you all the first underwater submarine of Luminaris~*."

FWOSSSSSHHH

(Oceania Submarine)

"..." Everyone didn't know how to react as Hokuto looked at the half-rabbit boy "Does Nito know or did you do it behind his back?"

"..." Kreist averted his gaze as he heard "Huh..." Chiaki scratched his head uncomfortably "I think Nito would end up pretty furious.... I mean you just recently built the Selene..."

The yellow-haired boy smiled "Well, that's a different thing. Ahem... I think we'd better get going."

Chiaki and Hokuto looked at four "Adonis, Makoto, Mackie, Izumi. Be careful." Hearing that the three of them said goodbye to everyone while Hokuto looked serious "Return safely."

Kreist nodded "We will. We'll be back before the chicken crows." After that they all boarded the sub and entered through the side airlock connected to a ramp with the dock before separating and closing the airlock as the sub began to submerge.

FWOSSSSSHHHH...

The Oceania began to move forward through an underwater tunnel as an underwater door opened in front of it, letting the huge submerged vessel get out into the open sea.

A few minutes later.

Nathan smiled at the view from the bridge of the deep sea.

A crew member who was listening on the phone nodded before hanging up, "Captain, we have just passed the storm that protects Luminaris. Hearing that Nathan smiled "To the surface!"

FWOSH.

Suddenly the submarine began to ascend and emerged on the surface of the sea.

Kreist who was also on the bridge looked on proudly "Looks like everything is going smoothly~*" Nathan gave the order. "Stop engines."

A few minutes later they all entered the bridge as they looked at the captain and Kreist who were waiting for them. The Royal Academy leader smiled "It's about time you guys showed up."

Yuuki smiled excitedly "It's amazing that for the first prototype it works great." Kreist laughed in amusement. "When I see those movies at Ensemble Square I knew my next project."

Nathan smiled crossing his arms "Although it doesn't look like it. It was secretly built it in only 3 weeks. And he tested for 1 more week."

Adonis, Yuuki, Mackie, Izumi: "WHAT?!"

Kreist coughed as he looked at a compass in front on the center table. "This is a special compass used to find Atlantica. It actually needs an object that came from Atlantia to work." He pulled out an object revealing a gem.

Yuuki looked confused "A gem?" Kreist denied putting it on the compass "Not just any gem, it was a gift from the leader of Atlantia who gave us the four or representatives of the four races. In total there are 5, the fifth is Nito's which represents a golden color. This has been kept by my family for hundreds of years. It was a symbol of unity among all and that includes Atlantia, the gem is made by a crystal that is only able to create in Atlantia itself. The compass where the element is no matter where it is."

At that instant the compass began to activate revealing an arrow pointing northwest. The rabbit boy nodded "We have a bearing."

Nathan smiled as he gave the command "ADVANCE ALL! Follow the arrow!"

Bridge crew "AYE CAPTAIN!"

The submarine began to move along the surface at high speed, moving deeper into the sea as far as the eye could see.

Arcaic City.

Nito was sitting in his office as he pulled out of his desk drawer a picture of him and a blond boy while in the background was Atlantia "..."

Returned with the others on the submarine.

The Oceania was moving through the waves of the sea following the compass. In the superstructure of the submarine Makoto was observing the sea "..."

"You are very distracted. Makoto." Kreist came up beside her watching the scenery. "I feel guilty for secretly leaving without saying anything to Nito..." Hearing that the boy next to him denied "Truth be told your anger is understandable after the Savanaclaw incident. But there is something else he didn't tell you about Atlantia. The leader of the city and the Lux Archon were close friends, besides that.... He partly feels guilty for not arriving in time to protect Atlantia in the Archon War."

Yuuki lowered her gaze somewhat sadly "I didn't know about that." Kreist a surged as he looked up at the sky "Yuuki.... Nito has been through a lot during these 4,600 years there are things he doesn't prefer to talk about."

"I see."

DING!

The speakers in the superstructure blared as a Nathan voice came out of them "Lord Kreist, Yuuki. Enter the submarine immediately. We dive." They both nodded as they quickly entered the sub securing the hatches.

Slowly the submarine began to sink below the depth is the sea and finally end up underwater. They didn't know how long the trip would last but they had enough food for three months.

Days passed and Yuuki had time after time every night the same dreams. "..."

Yuuki looked around. He was standing in front of a huge hall as he saw in front of him a huge pedestal filled with beautiful crystals. "How beautiful..."

In that instant all the crystals started to turn black.

PWOSSHHHHH!

Out of nowhere, water began to fill the room as Yuuki for some reason knew where he was and ran through the gardens until he reached the outside only to see something horrible.

"Atlantia... Is it sinking!" Yuuki looked at how the upper barrier there were holes where a large amount of water began to fall from the holes flooding the city.

The blond looked alerted "I don't remember dreaming this the other nights."

PWOSH!

Yuuki noticed a wave heading towards it which he quickly covered himself "AAAAHHHHHHHH!"

PWOSH!

The idol immediately woke up tense and scared".... What was that... Did Atlantia..."

"Yuu?" Mackie who was on the side bed woke up "Are you okay? You had the Atlantia dream again?" The Trickstar idols nodded "But it was more like a nightmare."

Mackie looked serious as he threw off the covers and sat on the edge of his bed "Tell me about it." Yuuki explained somewhat panicked as his twin looked serious "Atlantia was sinking.... It's kind of late to explain, how about you tell Kreist and Nathan tomorrow?"

He nodded as Mackie noticed Yuuki's hands were shaking in fear "..... Come." He got into bed as he pointed to a space inviting him to share his bed.

Yuuki nodded as she laid down next to him covering herself with the blankets. Mackie smiled "Yuuki, whatever happens when we get there you're not alone. Myself, Izumi, Kreist, Nathan and the crew of the Oceania will be by your side to help you."

He nodded as they both fell asleep while the submarine advanced beneath the surface.

The next day...

Kreist and Nathan were meditating on what Yuuki had just described in his dream. Kreist looked serious "I think I know what you saw about the crystals. They were created by Nito to control the city a long time ago, we were testing on seeing if Atlantia could submerge and with your dreams you can tell it worked but hearing that they turned black and the barrier around the city has started to dissipate is not a good sign."

"What are those crystals that Yuu-kun dreamed of?" Adonis was curious as Kreist spoke seriously "It is known as the Crown of the Sea. The crystals were created directly from Nito's power. We also needed time for them to work with the city and allow it to submerge but don't expect it to actually work or it could be..."

Nathan looked serious "It submerged to protect itself, but didn't you say they were not strong enough?" Kreist nodded as he looked out of the window of the Oceania "That's right but.... We're not sure how, it was impossible unless something had to happen that time."

Nathan nodded seriously "I'll order us to move forward at maximum speed." Hearing that Kreist nodded in agreement.

Archaic City
Valyrie Palace

Nito walked along with Rukio and Nicredo through the corridors. Nicredo crossed his arms "I heard Kreist is in Elderigh on urgent business so he must be very busy." At that Nito denied "Hopefully he's not making up another one of his crazy inventions.... That boy needs to learn self-control."

Rukio then remembered "Come to think of it. Yesterday I went to see Uncle Hajime, Uncle Tomoya and Uncle Mitsuru and there was no sign of Uncle Izumi, Uncle Mackie and Uncle Makoto." The blond looked curious "Weren't they at Ensemble Square, son?"

His son denied "Nope, they say they're busy to something like that..." Hearing that Nito had a bad feeling and looked at one of the guards "You." The Celest Knight's approached "Yes, your majesty?" Tell Kreist for me to head immediately to Elderigh to see how is Kreist. And tell Leon to investigate Royal Academy if he is there and tell them to contact me as soon as possible if they know anything." Hearing that the Knight nodded withdrawing.

Nicredo looked serious "Dad?" The Ra*bits idol nodded "Let's go to Ensemble Square."

Ensemble Square.

At the entrance a woman stood at the counter "I'm sorry your excellency. Eichi is in a meeting right now so he can't attend to you." Nito sighed as he nodded "I see." The three of them walked out while Nito knew another person he could ask.

Yumenosaki.

Nito stood at the entrance "It's been a while since I came here..." He smiled wistfully before walking inside along with his two sons. He remembered the copy he created in his Plane of Euthymia but nothing could compare to the real one.

The students who were in the hallway and even some teachers froze when they saw Nito who had a serious look "..."

At that moment he and his two sons stopped as Nito stopped a certain door "Nicredo, take care of your brother and wait for me out here."

The dragon boy nodded as the blond burst in.

BLAM!
