2 years, 5 months, 16 days, 02:34:23 after the Third Honkai Eruption.
It began as a normal, peaceful day for the residents of Soukai City.
People were busy with their daily lives—school, work, and everything that kept them occupied.But that peace shattered the moment a massive shadow passed over the city, forcing everyone to look up.
A colossal, alien-like battleship hovered above Soukai City, descending slowly as swarms of Honkai beasts and mech units poured out around it.
Immediately, the Soukai City alarm blared to life.The emergency broadcast system crackled:
"Major, unidentified flying object sighted above Soukai City! Location: SH0639. Optical readings cannot discern the nature of this UFO. No bio-energy readings. Scans of the interior have failed. Clusters of small Honkai Beasts and Mech units detected. Battle plan deployed and validated. Deploying drones to cover Valkyrie boarding action."
Evacuation began at once, civilians fleeing while drones soared into the sky to assist incoming Valkyries.
On the rooftop of a smaller building, a familiar figure stepped forward to observe the threat—Kiana, wearing her White Comet battlesuit.
From her earpiece came Himeko's voice:"Double time, Kiana."
"Aye, aye, madam! Don't rush me. It's hard work out here!"Kiana inhaled deeply, opened her eyes with a confident smirk, and watched the drones streak past her, firing at Honkai beasts.
A drone exploded in front of her, the blast wind whipping her hair, but she remained unfazed. She tapped her earpiece, brought up her visor, and sprinted forward. With a flip and a jump, she raised her leg as a drone jet passed beneath her—
And a giant, metallic cat paw materialized and smashed the drone aside.
Himeko's voice crackled immediately:"Geez. Maintain discipline, soldier."
The resulting shockwave sent Kiana flying, but she landed perfectly atop another drone jet.
"Himeko, I'm off!" she shouted as Honkai beasts swooped toward her.She opened fire with her twin guns, mowing down enemies with ease.
"Haha, piece of cake!" Kiana laughed.
"Kiana, activate the burst system and get this battle over with!" Himeko ordered.
Orange light surged around Kiana as she activated the burst system, summoning massive mechanical cat paws to crush anything coming near her.
But despite her efforts, the sheer number of Honkai beasts overwhelmed the drone, causing it to spiral down and crash into a building. The impact toppled one structure into another—but the second building miraculously held.
Kiana leapt out unharmed, landing on the remaining platform.
Surrounded again, she defeated the Honkai beasts swiftly before contacting Himeko:
"Himeko… The aircraft was destroyed…"
Himeko groaned audibly through the earpiece."(Groan) Save the explanations for later. I'll send someone to get you now."
Kiana nodded and continued fighting, holding her ground until—
"Kiana, your ride has arrived. Keep moving forward."
Kiana hurried ahead, stepping onto a bar hanging over the ruined edge. From there, she saw hundreds of Honkai beasts filling the sky. She was about to retreat when—
A giant flaming bird burst through the clouds, incinerating every Honkai beast in its path before descending toward her.
Kiana relaxed. She knew exactly who this was.
As the firebird approached, its flames dimmed and its form shrank—until floating before her was Kouga, clad in Kamen Rider OOO's Tajador Combo.
"Did I keep you waiting?" Kouga asked, the smile behind the mask practically audible.
Kiana grinned."Nope, not at all, Kouga-senpai."
Himeko interrupted their brief moment:"Kiana, you and Kouga need to enter the Selena ship."
"Understood, Himeko."
Kouga nodded toward her."Well then, let's go, Kiana."
He wrapped his right arm around her waist and lifted them both into the sky, heading straight for the massive battleship now identified as Selena.
The two flew high above the clouds and descended toward the enormous battleship Selena.
Kouga opened a comm channel."Major Himeko, the Selena is within sight!"
"Roger. Prepare to land, Kouga, Kiana." Himeko replied.
Once they were close enough, Kiana removed the visor from her eyes as she and Kouga touched down on one of Selena's outer passageways.
The moment they landed, Kiana received a call. She answered it, and a hologram of Himeko flickered into view.
"Kiana, status report."
Kiana replied confidently while Kouga scanned the surroundings for enemies."Kouga and I are on deck! Everything's going smooth, Himeko!"
Himeko's expression sharpened."I've said it many times, but I'll say it again: You may only address me as 'Major Himeko!'"She took a breath to calm herself before continuing."Ahem. 30 minutes before the battleship crashes. We must seize the helm of this battleship. We cannot let it destroy Soukai City! Your teammates are in position. They will rendezvous with you in a while."
Kiana's eyes lit up with excitement."Mei!! You're talking about Mei, right? I'll be meeting up with Mei, right?"
Himeko sighed."Ok you need to calm down. And stop being so obsessed about Mei! And besides, Kouga is here too, isn't he."
Kouga was still quietly observing the area.
With another sigh, Himeko continued."Stay vigilant. We've lost track of that Emperor-class Honkai Beast you've fought."
Kiana scoffed, full of confidence."Pfft. By the time that idiot comes around, I'll be riding this battleship home."She ended the call herself and rushed forward, darting past Kouga.
Kouga's own call came in. He answered immediately."Yes, Major Himeko."
"Kouga, please watch over the girl."
Kouga nodded."Yes, I have always been doing that."
He quickly followed Kiana.
As they advanced, Kouga shifted from Tajadol Combo to Ryusoul Red, wielding the Ryusoul Ken to slice down Honkai beasts, while Kiana cleared the rest with her twin pistols.
After a short while, Kiana received another call. Mei's hologram appeared—she was in her Crimson Impulse battlesuit.
"Kiana, Mei reporting. I'm safely in position."
Kiana's face lit up."Mei!! Awesome! I'll head over right now!"
"Hey, wait. We should follow the battle plan…" Mei tried to explain.
"We're the bestest partners! We must stick together to make things easier for them." Kiana insisted.
Mei corrected her gently."I think it should be 'make things easier for us.'"
"Oh dear! Whatever. The battle plan also allowed us to be 'flexible and respond as required', right? Just wait for me!"
Mei then glanced to her left and saw Kouga approaching. She smiled as he greeted her.
"Hey, Mei, how's it going?"
"I'm in a safe position."
Kouga nodded."I see, please be careful, Mei."
"Thank you, Kouga-kun."
They were interrupted when Kiana suddenly pouted."Hey, don't ignore me."
Kouga and Mei shared a small laugh before Mei closed the call.
Kiana and Kouga continued forward, heading toward Mei's location. Kiana could barely contain herself."Can't wait any longer! It's already been 2 hours, 27 minutes, and 38 seconds since I've last seen Mei!"
Kouga could only sweatdrop.
They fought their way through zombies and Honkai beasts until finally reaching the hallway where Mei had finished her own battle.
Mei stood calmly, sheathing her sword."Hmm, that's about it."
Before she could turn fully, a Honkai beast lunged from behind—but Kiana burst in, kicking it away, with Kouga following through with an energy slash that obliterated the creature midair.
Before Mei could react, Kiana wrapped her arms around her from behind in a tight hug. Kouga watched and chuckled at the scene.
"Mei! We'll get the strength of a hundred warriors if Mei's around!" Kiana declared proudly.
Mei blinked."A hundred? I'm no ultra woman…"
"I meant that if Mei's around me, I can feel my power increase one-hundred fold!"
Mei giggled softly."That's really something only you would say, Kiana."
