After descending for what felt like an eternity, the Hyperion finally reached the seafloor.
Outside the massive observation windows, darkness ruled the deep ocean.
Yet within that darkness shone a breathtaking sight.
The Deep.
A vast underwater city slept beneath the waves.
Ancient towers of silver-white metal rose from the seabed . Transparent crystal structures glowed softly with pale blue light, illuminating the surrounding waters. Massive arches connected towering buildings, while countless luminous particles drifted through the water like stars scattered across a night sky.
Schools of strange bioluminescent fish swam between the ruins, their light reflecting off polished surfaces that had somehow survived thousands of years beneath the sea.
Unlike most Previous Era ruins, which were little more than shattered remains, The Deep appeared remarkably intact.
It felt less like a ruin and more like a forgotten city frozen in time.
Even the surrounding water seemed strangely calm, as if the ocean itself respected the ancient civilization resting beneath it.
For a moment, everyone aboard the Hyperion simply stared in silence.
Einstein: "11°20.9′ N 142°11.5' Ε. 6152 meters below sea level. This is The Deep, ruins of the Previous Era found by AE. Te moana kino, the malevolent sea."
Outskirts of The Deep, a massive underwater ruin.
Theresa's eyes widened in amazement.
Theresa : "WHOAH! This looks awesome. I've seen plenty of Previous Era ruins myself, but The Deep seems so... undamaged!"
Einstein nodded.
Einstein : "Being underwater shielded it from much devastation."
Liliya looked toward the city.
Liliya : "To seize the Gem of Desire, Schicksal has been attacking AE bases for months."
Rozaliya crossed her arms.
Rozaliya : "More and more enemies came at us, so Matushka chose to keep the Gem here to protect it."
Theresa frowned.
Theresa : "That won't work forever. Schicksal will eventually find out."
Einstein checked her sensors.
Einstein : "No. They're already here. I've picked up signals from a large battle. Tactical mechs have engaged Schicksal Valkyries."
Liliya froze.
Liliya : "What...?!"
Rozaliya's face paled.
Rozaliya : "This shouldn't be happening! Everything was peaceful when we left."
She immediately turned toward the city.
Rozaliya : "Let's go! We must go down and save Matushka."
Theresa immediately switched into command mode.
Theresa : "All crew to battlestations! Assist the mech troops and fend off the hostile Valkyries!"
Everyone prepared for battle.
Rozaliya.
Liliya.
Theresa.
Bronya.
Moments later, the Hyperion landed near one of the city's entrances.
The group quickly entered The Deep.
The once-beautiful streets of the ancient city had become a battlefield.
Destroyed mechs littered the roads.
Energy blasts illuminated the underwater corridors.
And dozens of Schicksal Valkyries were pushing deeper into the ruins.
Theresa immediately assessed the situation.
Theresa: "We've arrived at The Deep. Hostiles have entered the ruins."
Seeing the sheer number of Valkyries, Bronya silently grabbed the blue crystal necklace hanging around her neck.
She focused her will into it.
Rozaliya noticed.
Rozaliya : "Bronya, what are you..."
Her voice slowly faded.
Six blue translucent silhouettes began forming beside Bronya.
Red Buster.
DekaBreak.
Kamen Rider Kabuto Rider Form.
Kamen Rider Drive Type Formula.
Kamen Rider Mach.
Kamen Rider Accel Trial.
The six warriors stood silently.
Rozaliya and Liliya stared with sparkling eyes.
Theresa nodded approvingly.
More allies were always welcome.
Theresa : "Okay everyone get rea...."
She never got to finish.
The six blue warriors vanished.
BOOM!
A sonic shockwave erupted through the corridor.
The next thing everyone heard were screams from the Valkyries.
Several minutes later.
The battle was over.
Almost every Schicksal Valkyrie encountered by the group had been defeated.
Many of them were tied together into one gigantic rope-like bundle.
Theresa couldn't help feeling a little bad for them.
Bronya noticed movement in the distance.
Bronya : "Hostile forces retreating."
The summoned Riders and Sentai warriors immediately prepared to pursue.
Einstein stopped them.
Einstein : "Cease pursuit. We have more important things to deal with. We need to find Cocolia."
At that moment, a familiar voice echoed through the corridor.
Cocolia : "Never expected people to care for a vixen like me."
Everyone immediately turned around.
Standing at the far end of the corridor was Cocolia.
Several Anti-Entropy mechs stood behind her as escorts.
She wore her usual confident smile despite the ongoing battle.
Cocolia slowly approached the group.
Cocolia: "You're most welcome, Dr. Einstein...and...the Hyperion crew."
