Kiana and David started with a cross-strike, clashing with each other.
"Incandescent Flower, here I am!" Kiana then tried to stab David with the Abyss Flower.
David dodged with Sandevistan, so Kiana swung the Incandescence against him. David blocked the sword with Viola's sword, which...
activates Sandevistan?* "Whoa! Miss Viola's Witch Time automatically and forcefully activates Sandy!?" David gets the Witch Time from Viola, as a result of blocking dramatically.
David got the idea and now know Witch Time, so he fully dodged Kiana's sword and immediately slashed. This makes for a good hit, knocking Kiana off.
"Ugh! How do you even...!?" Kiana is hurt.
"I have Sandevistan, but this sword bright me the Witch Time, which forcefully activated the former." David explained.
"This is gonna be lunarly interesting fight." Kiana then hit David so much.
Kiana went out on striking David with what she got. So: manipulated fire, she generated technological guns, used portals and gravity wells, and manifested tangible illusions, all to hurt David over and over. But comes the Witch Time, David exchanged with that and slashed Kiana as well as shooting her, before Sandevistan deactivates and Kiana get to damage David again. This all turned into some almost-acrobatic mess, with the two fighters exchanging blows and counters, all inside the Purgatorio.
Meanwhile...
"You left because the cubes corrupts?" Genjitsu-no-Omnia questioned the Origin. "Fair point."
"What did you do to the island?" The Origin asked. "Is that was the first time it has been destroyed?"
"Actually, I have destroyed the island over a thousand of times, by breaking the Zero Point." Genjitsu-no-Omnia revealed. "That body Zero Point somehow remade the island everytime I did because of some shit!"
"That's why I burned the Reality Tree in its source variation. This was the true source." Genjitsu-no-Omnia continued. "Now that I've destroyed the true original source for that crazy island and devoured all its powers, the Zero Point is truly no more, and the island is existentially gone for real good!"
"Then... you killed almost all Loopers in all of existence!?" Geno is shocked.
"You disgusting abuser, trying to protect the island through nefarious means." Genjitsu-no-Omnia looked down upon Geno. "That's ironic of you, and ruinous for those shitty Loopers."
"As for you, the King... your departure frustrated me so much, the Queen should've comforted and allowed me instead of shunning me!" Genjitsu-no-Omnia vented her traumas. "And as for Ariana Grande... I hope you regret stealing the title 'Goddess of the Rift'!"
"So you're the true Goddess of the Rift!?" Geno asked back.
"The Last Reality treats the higher-ups and their trusted peoples as deities." Genjitsu-no-Omnia explained. "Me, in particular, because I'm the main caster of the dimensions, they once called me the title: Goddess of the Rift."
"It all changed because of my attitudes following your departure, your Highness." Omnia mocked the Origin, and kicked him in the helmet.
"You're far over the edge and over the holy range, even by the Last Reality's standards!" Geno then powered up and tried to tackle Omnia with his power of creation.
Genjitsu-no-Omnia effortlessly ripped Geno's right hand off with her bare hand, but his hand quickly regenerated. Omnia simply choked him in response.
"Urgh... You...!" Geno is stuck.
"Not even your over-the-limit, omnipotence, omnipresence and omniscience can ever save you from my wrath." Genjitsu-no-Omnia mocked Geno. "For me, even all the omnideities in every single worlds and realities are totally nothing but a literal negative asshole to 'nothing', let alone me! And are you even an omnideity at all? You suck!"
Genjitsu-no-Omnia punched repeatedly on Geno, eventually to the point blood gouged out (much to Origin's horror). Then she threw him into a load of CRT-TVs, destroying them and revealing a black hole that was previously sealed by the CRT-TVs. This sucked both Geno and the Origin out, though the latter managed to grab Omnia's leg.
"Thanks goodness, I have been grabbing and recording everything here all along!" The Origin revealed the Akasha Terminal.
"You disgust me!!!!!" Genjitsu-no-Omnia screamed.
"This is Origin, out least for now!" The Origin then deactivated Akasha Terminal and let go, getting sucked in as a result.
"Hmph." Genjitsu-no-Omnia then sealed the black hole and then left.
"Noooo...!!!" The Imagined and the Order, who happened to be the twin daughter of Geno, received everything the Origin sent.
The twins, totally broken in years, cried hard and crouched down in fear and despair. The rest of the Seven as well as SMG4 and friends, also all received everything the Origin just sent...
"How ridiculous she is...! She beat up the wrong 'threats' in front of her king!" SMG4 complained.
"Oh. My. God!" Tari is shocked.
"What the hell!? She's even more deranged than we ever imagined, let alone thought!" The Paradigm is frustrated.
"Firstly, Genjitsu-no-Omnia is indeed deranged far beyond comprehension." The Scientist took note. "Secondly, we found out a bit of her backstories, and it matches a lot of what Miss Amaterasu described."
"Thirdly, she just offended and beat up both the Origin and Geno, both physically and mentally, all at a quick succession." The Scientist reported. "And finally, turns out that she intends to transcend even the omnideities and all the likes altogether."
"In addition... did she mention that Ariana Grande stole the title?" Meggy asked.
"That's really sus, you know..." SMG4 replied.
"The Loopers thought that Ariana Grande was the Goddess of the Rift?" The Paradigm questioned.
awkward silence*
"Wait... there's a concert held by Ariana Grande... on the Reality Zero!?" The Seven (except Imagined Order) and SMG4 and friends are shocked.
"Did I hear... the Goddess of the Rift?" Ms. Continuum appeared.
"What!?" SMG4 is shocked.
"Who are you?" The Foundation questioned.
"I am Miss Continuum, acting as an Akatsuki." Ms. Continuum introduced herself. "I am from the Continuum Exploitation Authority, or CXA, as a acronym."
"Oh, so you're the Seven, but no Origin anywhere." Ms. Continuum recognized. "What happened to the Origin?"
The Scientist explained the details of Genjitsu-no-Omnia abducting, disrespecting and beating up both Geno and the Origin.
"She just tried to get rid of the Origin and the leader of the Imagined Order!?" Ms. Continuum is shocked.
"Oh yeah, note that the Origin was the Cube King." SMG4 clarified. "Also, by the look of the backstory, it's clear that Omnia absolutely traumatized by the Last Reality, the Imagined Order, the Seven, the Loopers and the island, and hates them all from there on out."
"By the way... Have you watched the original livestream, which has Omnia destroying the Zero Point?" Tari asked Ms. Continuum.
"That's...!" Ms. Continuum is shocked. "There's Master Jones...!?"
"You mean Agent Jones?" The Foundation questioned.
Ms. Continuum kneeled down herself, feeling depressed.
"Genjitsu-no-Omnia killed Jonesy, and I'm terribly sorry for finding that out..." Meggy commented.
"How could Omnia did it to Master Jones..." Ms. Continuum cried. "Once I saw her killing him, shown in that livestream, I...!"
The Imagined and the Order quickly hugged Ms. Continuum.
"That bitch recently beat up our father, and sucked him and our fellow into a black hole!" The Twins told Ms. Continuum.
"And thanks to Omnia's insanity, the omniverse is broken!" SMG4 concurred.
"Therefore, we're officially joining the CXA!" SMG 4 and the rest saluted.
"Thank you...!" Miss Continuum thanked all. "You're welcome!"
Meanwhile...
Few minutes into the fight, both fighters are exhausting themselves upon counters and blockoff. David is especially tired, because he's pushing himself to fight, leading to him bleeding semi-internally (such as coughing blood). Just when he managed to throw Kiana completely over and off-balance, Kiana acrobatically recovered, then gets back up elegantly yet dominantly. David fears that she's not yet taking it seriously, as the intensity build up in the air... This is followed by a flaming torrent of starlights being blown into the air, knocking David out without the slightest understand if what's happening.
David blurred out as he's spun about, and before he can tell up from down, he impacted and slammed into the ground, collapsing as if he's losing.
"Am... I going to die... again?" David flashbacked at everything single thing he has experienced in his current life. Just like the story that you see your life flash before your eyes just before you die. "Am I dying...? Can I really accept that...?"
"I'll fight as much as I have to, in order to save our people and the reality!" David then resolved for it. "I have to keep going! I've come so far... I can't lose heart now!"
David desperately forced his legs to move, and managed to stand up again. Kiana stopped as well, and stored her weapons with an air of finality.
"Wow... you managed to back up and keep up with me." Kiana is impressive. "It seems you possess true strength, belies your... scary parts."
All the powers, even the unyielding torrent of burning starlight, suddenly ceased.
"So you probably were at the limits of your stamina and resistance after the battle against that punky witch earlier." Kiana noticed Viola. "In fact, it seems like you nearly gave in during this foregone sparring we just did."
"But... just as I have experienced and what Velvet Room said," Kiana continued. "each time you faltered, the many supporting you gave you more strength to protect, helping you to get back and rise again." *nods*
"This was a good fight." Kiana concluded her speech. "I'm glad that our encounter has done favors."
David silently took a break, alongside Viola who's lying collapsed.
"May I ask you something?" Kiana noted David. "To continue fighting in order to protect all that's beautiful in the world from an undesirable future... A path of endless hardship."
"Have you choose to walk it?" Kiana asked. "I already did."
"Yeah, learned it from Mr. Narukami and the Velvet Room." David agreed. "Working a better tomorrow isn't just a one-time thing, 'cause tomorrows just keep coming."
"Therefore, going beyond the edge, with a path beyond that door... I would keep fighting." David concluded. "For the future safe from unwanted hell!"
Kiana smiled at the answer.
"We'll meet again, David Martinez." Kiana said bye. "By your leave, I, Kiana Kaslana, am out of here!"
With this, Kiana entered a portal, then it closed. Another portal is left behind, leading to the other side of the invisible wall. David also realized what Yu meant about true strength, as well as something the Velvet Room taught this far.
David called that fight a draw. And as he waved goodbye to Kiana, he heard Viola getting to her feet behind him.
"Ugh... My name is Viola, amd I'm an Umbra Witch!" Viola recovered. "And what?"
"Are you alright?" David went to Viola. "You shouldn't force yourself to move."
"I'm fine, you idiot! But you're very kind..." Viola shrugged David. "We've only just met, and yet you are worried about a daughter like me, just like Mummy..."
"Miss Viola, isn't that normal?" David asked back.
Viola simply laughed off the confusion.
"Seeing you smile like that... duh." David responded. "I just think of you as someone I needed to protect."
"You still have a great, right?" David continued. "Then it doesn't matter who you really are."
Viola stopped laughing and thinks deeply for a moment. Then...
"Now that you've beat me in the combat, the rules mean I cannot continue forward!" Viola questioned. "However, I believe you. Will you listen to the mission directive?"
"Yes." David agreed.
Viola said the directive, and it's surprising to David: it involved a certain combination of angels, demons and even Homunculi. Viola previously fought alongside versions of her mother, Cereza (a.k.a. Bayonetta) against various versions of Dr. Sigurd as the Singularity, in the Multiverse belonging to, involving the Trinity of Realms. Viola suggested that the current situation came to be because some certain version of Singularity sabotaged the TV world and caused it to be fused with the remains of Reality Zero, creating more Shadows in the process.
"So... there's Singularity... fusing the TV world with the island and created some Shadows, and that's the reason why this all happened?" David asked.
"We came to this to eliminate the Singularity and the Shadows." Viola replied. "My colleague, the descendant of the cowherd and the weaving girl, 'Hoshimatsu'/'星祭', is in this somewhere..."
David realized that it's about Nanako, the Cube Queen, some Shadows, the Singularity, and now... Hoshimatsu.
"Tell me more about Hoshimatsu, and I'll do what what I can to help you get her back." David suggested.
"Unfortunately, she's missing for..." Viola responded.
Viola's expression clouded.
"So you don't know what she looks like, what she can do, or what equipment she's having." David concluded that all Viola could tell was that Hoshimatsu is a descendant of the cowherd and the weaving girl. However, he realizes that he met a girl who's a descendant of the Summer Triangle... it's Miss President!
So David connected proofs with the story of Summer Triangle, 'the Cowherd and the Weaver Princess'... could Miss President be Hoshimatsu?
Miss President, with her spiky, perhaps starry, ponytail, came to mind.
"Is there a possibility that she's well... an edgerunner nowadays?" David questioned. "You mentioned earlier that she was your colleague, so I assume she's also your partner, but..."
"She was my partner who went through many worlds." Viola discussed. "It's doubtful that she'd become a cyberpunk though."
David then realized that it's complicated.
"Alright. In any case, I'll keep an eye out for her." David decided. "But right now, I'm heading to the Announcement Room, inside the Announcement Zone. I'm bound to meet up with Hoshimatsu eventually."
"Thanks. I'll trust her fate to you." Viola nodded.
David gave a determined nod and entered the portal.
