The light subsided, and Rumia was on her rear end, against the wall. In front of her, the metal that made up Rika's base was stripped away, the tank nowhere to be seen, and a hole blasted through the wall, revealing a massive cavern, which led up to fresh air. There were massive thuds above, as if something giant was stomping on the ground.
She looked from side to side. Everyone was down, groaning, but getting up.
Except for Alice, who had an unconcious Marisa on top of her. You swear the puppeteer was blushing a little at the situation, as she complained about Marisa being heavy, the witch pinning her arms.
"'Comon Sis. You should be strong enough to move a human." Rumia teased.
"You're not my Sister just because you're from Makai Rumia." Alice groaned. "And I'm weak for a youkai, physically, probobly weaker than most humans. Magician youkai aren't stronger than humans, in fact, most are weaker."
Wriggle, Rumia and Mystia rolled Marisa off Alice, who then got up, as Reimu looked up the large tunnel in the next room.
Nitori looked too, and then, gulped.
"Guys. This is... a hangar." Nitori said.
"A hangar?" Rumia asked.
"Something used to store a vehicle. Something just came to the surface from down here, and judging from the size of this room... it was huge." Nitori explained, as Ruia 'borrowed' the Hakkero from the unconscious Marisa, feeling she may need it.
Everyone started flying up the 'hangar' and to the surface.
Then they knew exactly why Rika had not been seen for ten years.
"... That's impossible." Nitori said. "Even the whole Kappa Village couldn't do something like that."
The earth shook, and Letty's eyes opened. However, it was Cirno who saw it first, Letty looking to Rika's base, not the location of emergence.
"Wow, Letty! It's Daidarabotchi!" Cirno said. "I saw him a year back! He ran away from me because I'm The Strongest! Finally showed up to fight, eh!"
The titan moved foward, and the ground shook again. Letty looked at Cirno.
"Well, Cirno, it looks like you'll get your match. But be careful. I've fought Daidarabotchi before, and he fought me to a draw."
"Wait, he's as strong as you?" Cirno said.
"Maybe stronger. But together we can win, right?" Letty said, knowing just what buttons to push, so that Cirno wouldn't dive in too recklessly, but would be of use anyway.
Cirno thought for a few moments, before nodding. "Yeah! Let's work together Letty!"
"Something that big is probobly gonna attract others to help out too, you don't mind, right?" Letty said.
"Eh, they want some of the fun I say let them. It's Winter after all!" Cirno said happily.
The fairy and the Yuki-Onna flew towards the giant.
It was massive. At least a third of the size of the mountains. It was a humanoid titan, made of pitch-black metal, with an orb-like head, with a huge eye, like some sort of cyclops. It had two massive wings on it's back. Just under the eye, was a red 'Omega' mark, and in it's chest was a see-through panel, where the reactor was clearly visiable, as if taunting the creators of it for allowing the means for such a monster of technology to be powered.
"Cower, youkai! This is Evil Eye Omega, the Instrument of your Genocide!" Rika's voice said from the robot, looking down on the small group.
"Everyone, at once! Target that panel!" Reimu said.
"Water Sign: Kappa's Flash Flood!" Nitori declared, before the snow in the air and on the ground around her liquified, and rushed at the titan.
"Grand Finale: Seven Colored Magic!" Alice yelled, using her Grimoire and her strongest dolls in unison.
"Migrating Spirit: Fantasy Seal -Dark-" Reimu delcared, before her Hakurei Orbs around her and Genji multiplied, before launching a tremendous focused barrage, far out-stripping any of the other attacks.
"Bird Sign: Mysterious Song!" Mystia declared, before forming multiple bird-familiars, which rushed towards the mech, streaking around the other attacks, adding power.
"Wriggle Sign: Nightbug Tornado!" Wriggle declared, a massive amount of firefly familiars forming around her, swirling, and unleashing a torrent of blasts.
"Moonlight: Full Moon's Ray!" Rumia declared, using what amounted to a stronger, altered version of her 'Moonlight Ray' spellcard, which instead of using the lasers to box in her target, instead fired two aimed lasers from different angles, along with a wild scattering of other projectiles.
The attacks all hit at the same time, and there was a blast, as the mech stumbled back half a step. However, Rika just laughed, and as the smoke cleared, even the strongest attacks of the group had done no damage.
"I implied it. It's so hilarious that you didn't figure it out, that you hold onto the slightest bit of hope. I designed this mech with anti-magic shielding. Except this mech has even more advanced technology than that tank. Although, I gotta admit, I borrowed the basis of the technology from someone else a few years back... oh I'm talking too much." Rika boasted, as the mech leveled an arm towards the group, each finger seeming to be a cannon like on the tank.
"Just die." she said, as each finger unleashed a torrent of blue flame.
"Blizzard: Jack Frost's Breath." a voice said, as a huge blast of cold air and snow blew away the flames, back into Rika's mech, causing her to stop her blast.
"Who dares!" Rika yelled, the head of the mech turning 180 degrees.
Letty Whiterock floated in the air, with Cirno by her side.
"The Strongest Pair has arrived!" Cirno said.
Rika laughed manically.
"I should feel honoured! The Yuki-Onna linked with Winter itself has come to challenge me! But a youkai is a youkai, and a fool is a fool." Rika laughed.
"Am I supposed to feel saved because that weakling showed up?" Reimu asked. "She's not much stronger than Cirno."
"If I recall, you fought her during the Cherry incident Reimu. If that was the vcase, she would have been a mere shadow of her true power due to the falsely extended winter. The Yuki-Onna are heavily based on nature, almost as much as the fairies." Alice explained.
"So... she's a lot stronger now than then?" Reimu asked.
"She stopped Rika's flames just then, mistress." Genji commented.
"Usually, I dislike getting involved in fights. However, you aim to rip the peace of Winter apart with Genocide. You do not just threaten me, you threaten everyone, and would tarnish the memories people hold dear about winter. They would only think of your evils. I cannot allow that." Letty said.
"Feeling tough, eh?" Rika said, as the eye's pupil glowed red, before launching a massive red laser at where Letty and Cirno were, although they dodged, the snow turning into a massive blizzard.
"Me and Cirno have an attack that may be able to bypass her shield, but we need an opening first." Letty said, appearing with Cirno by the others.
"Hi guys! What brings you here!" Cirno says to Rumia, Wriggle and Mystia.
"Saving Gensokyo. You?" Rumia asked.
"Daidarabotchi!" Cirno said happily, pointing at the mech.
"... Well, Daidarabotchi has Daiyousei inside him as a prisoner." Mystia said.
With that, Cirno suddenly turned serious.
"Letty. Tell me what to do. My best friend's in there." Cirno said, her usual tone of voice gone, and replaced by something serious. This was a side of Cirno that Rumia had only seen once, for the briefest second, when Cirno had found out Daiyousei had been forced into helping Sunny, Luna and Star burn down her house, and turn the lake fairies against her. Dai, despite her intelligence and position in fairy society, wasn't even strong enough to have her own spellcard. Cirno saw her as a little sister that needed protecting, and Rumia knew if she had seen what they had seen earlier, Cirno would have doubtlessly lost control completely.
That had only happened once before, but the results were terrifying.
"Kappa, you have the ability to manipulate water, right? I saw you doing it just now." Letty said.
"Yes..." Nitori said.
"Good. We might be able to make an opening. Everyone except me, Cirno and the kappa, distract her. Kappa, prepare a lot of water, enough to make a localized wave big enough to swamp that thing, there should be more than enough water in the snow around here to do that."
"I-I've never done anything that big!" Nitori said, panicked.
"Do as much as you can. Me and Cirno will freeze the robot in the wave, which should buy us the time we need to strike physically." Letty commanded.
"I don't have any better ideas, Reimu." Genji said.
"Me neither." Alice admitted, adding, "Golaith can help with the physical strike."
"Your doll would get in the way. There will already be a torrent of fists." Letty said. "I've used my powers to send a message in the snow to the Nuuydou, who should see what the situation is. Their might combined should be able to break through the robot, or at least do enough damage to create an opening for me and Cirno to do a precision strike at the core."
"You can't do that! Damaging the core could lead to a nuclear detonation!" Nitori cried.
"Reimu can make a barrier to hold it in." Letty said calmly. "If Gensokyo is in danger, I'm sure Yukari would act as well."
"Your plan involves Yukari doing something as a failsafe? We're really doomed, aren't we?" Reimu said sarcastically.
"You know, I'm tired of letting you lot hide in this snow drift and plot. I'm just gonna switch to heat vision and... there you are, no more hiding in the blizzard!" Rika said, in a bored tone, and as if she could have done this all along. The madwoman was of the opinion that whatever the youkai had up their sleeves was doomed to fail.
Two panels opened on the shoulders of the robot, and about thirty small eye-machines flew out, towards the group, as Rika's robot started unleashing barrages of lasers and other attacks as well.
"Those eye things are the ones which lifted the Reactor away!" Nitori said. "They're pretty fast, tough and dangerous!"
"Then we need to be careful!" Rumia said. "We only got one shot at this, we'll buy time!"
"I know I'm asking a lot everyone..." Letty said.
"Don't worry. We won't let her beat us." Reimu said.
