"Daughter of Bayonetta and Luka." Viola revealed.
"Oh... so you're Inferno's victims' successor!?" System No. XX is surprised.
Eventually, everyone looked at Team Lobotomy-Ruina and Hoshimatsu.
"My mission to rescue you has brought me here." Viola explained to Hoshimatsu. "Rodin and the CXA are waiting for you."
"Considering what you've been through as well as how I didn't notice it..." Hoshimatsu responded. "I hate that Singularity."
"Don't worry, that will be dealt with." Viola smiled. "Right now, there's an important thing you need to do."
"I gotta help them, huh..." Hoshimatsu realized.
Viola and David pointed at the Shadows that has remained still while everyone are talking.
"It's okay, Librarians." David reassured them. "We're all right there with you and her."
David has indicated that the alliance gathered around. David has been forced to fight against his allies, but he managed to endure and overcome the suffering that Hoshimatsu had not. Of course, David hasn't been forced to actually fight to the death, and he wasn't alone at all, nor did he ignore that. David thought about all of it...
Hoshimatsu had been forced to endure all the pains even without directly experiencing it. But... she'll be alright now. It doesn't matter who she actually is. She's not alone anymore.
"Yeah..." Hoshimatsu proceeded. "Librarians, you can accept it."
With all that, Angela and all the Sephira slowly looked around all the faces, searching reach one for confirmation. Finally, they turns back to Hoshimatsu and all nods, then walks to face their respective Shadow. While they walks, Hoshimatsu no longer seems to be bound by her fear, but instead... feels at peace. She looked down at her, looking at her cybernetics that she had implanted to help her survive, but had she had convinced herself she didn't have.
"Accept and embrace it." Hoshimatsu told herself and the Librarians.
"That's right..." Angela and the Sephira accepted. "You're me."-"You're all us."
Angela and the Sephira and their respective Shadows turned to face one another and stared into each other's (respective) eyes.
"You're my human desires, vying for revenge... the free will distorted by vengeance... the perfect book wanting to be unleashed..." Angela told her Shadow. "You're how could I be human."
"You're the traumas that stuck, thinking inside a robotic box... the death that changed our existence... the conduit to a forbidden light..." Each of the Sephira spoke to their respective Shadow. "You're our dark side that born from our death."
"You're always inside me. You're all inside us." Angela and the Sephira told their respective Shadows together. "You're me, you're us, the inhuman things with a human heart."
"We're sorry we never noticed you all this time." Angela and the Sephira spoke. "We never caught you, but instead left you all alone..."
Angela hugged her Shadow, and the Sephira hugged their respective Shadow as well. "No... you're me and us, after all."
All the dark energies that left converted into bright lights, with the Shadows shining initially from bright blue light, transitioning into golden light as the librarians absorbed them all respectively.
In the end, only the Librarians among those remained, having absorbed their own Shadows. The Sephirot's current outfits also changed into that of their human life's but appropriately recolored and sized, in the process, while Angela's book turned into the perfect book as well.
Hoshimatsu calmed down, and the Librarians accepted the existence of their Shadows, and ended up getting much stronger and better as a result. It's final over... this tournament is no more...
Everyone got out of the black sphere, hospitalized Geno and the Origin, revived the dead participants, exterminated all the hostile Shadows in the island, rescued the attendants of the Velvet Rooms, and all returned to Athena Daybreak surface. The invisible walls are all gone. Hoshimatsu is also slowly warning up back to everyone (especially Viola and David), smiling more and responding to the alliance and members of CXA when start talking to her.
Then everyone scavenged all the remains of the Velvet Rooms that has been destroyed, and went to the dimensional tunnel the alliance went through to arrive.. The dimensional tunnel now lead to the studio-like appearance that the (original) Investigation Team was accustomed to.
However...
"God-Scientist!?" The alliance is shocked.
"David Martinez, we knew you would ruin the tournament at the last minute!" God-Scientist told David. "Thanks to that, you just saved someone I'd like to kill!"
"You're...!" Viola recognized the God-Scientist.
"Yeah, that's right! I am the son of Dr. Sigurd!" The God-Scientist introduced himself. "And as long as his DNA exists, Singularity isn't going anywhere! The essence will reach to me anyways!"
"Dr. Sigurd... so your father tricked Miss Cereza all along?" Reiji questioned.
"Bayonetta?" The God-Scientist laughed. "I remember her! Confronting my father just because he tricked her and Jeanne!"
"The Alphaverse would've sent regards, but she foiled my father's plan!" God-Scientist discussed. "At least she's dragged to fucking Inferno alongside her stupid lover!"
"You...!" Viola is angry.
"You disrespecting her parents!?" Hoshimatsu defended Viola.
"Alas, my father's killed by that witch when I was little." God-Scientist continued. "But that miracle struck because the Shadows received the essence before I do."
"By the time I finally received the essence, it was Empress Zero who brought me into it with the Shadows!" God-Scientist concluded. "Now I'm the ruler of the Shadow World!"
"You're even crazier than me..." Adachi is surprised. "Yikes!"
"Of course, as a scientist like father, I performed lots of experiments. In my case, those are brought up by Empress-" The God-Scientist further elaborated-
"You're the new Singularity?" Viola questioned the God-Scientist. "Then don't fuck with a watch!"
"That stupid one-liner from that witch again!" God-Scientist is frustrated.
"You got enough shitload, asshole." David pointed a pistol into the God-Scientist. "We got Rigna, then those Invaders, and then brainwashed Lucy, and then Prometheus, then stupid fake ceremony, and then P-1 Grand Prix, then Hoshimatsu's traumas and the Shadows of those Librarians, and now you?"
"Trying to bank the suffering into the wrong peoples..." Ren Fuji questioned the God-Scientist. "What's the moral with that? You're that crazy, befitting for one of Genjitsu-no-Omnia's servants."
The God-Scientist then took out the Keystones.
"My Keystones!" System No. XX noticed the Keystones.
"Why do you all have Keystones?" David asked the God-Scientist.
"The Shadows I summoned has stolen it." God-Scientist revealed. "Then I experimented it."
"You bastard!" System No. XX profane response.
"Fuck you, heartless offspring!" Shadow Labrys offended the God-Scientist.
"I don't fucking care!" God-Scientist responded. "I can become the ultimate Singularity!"
"You think this is funny!?" Ragna argued.
"I am the new Singularity, and when the time comes, I shall unleash the power of my bloodline, and exterminate you!"
The God-Scientist then suddenly got blasted from behind. He however doesn't flinch or get affected at all, aside from his clothes being vaporized.
"Who the fuck shot me?" The God-Scientist looked around.
"Found you!" Fifteen versions of a people shouted.
"No... the Doctors!" The God-Scientist is shocked.
"The Doctor!?" The alliance is surprised.
"What did I just get into?" The 14th Doctor questioned.
"You're the latest existing incarnation..." Angela noticed. "Welcome."
The 14th Doctor looked at the 10th, and both are shocked.
"Whoa! Who're you!? Me!?" 10th and 14th is shocked.
"Where am I?" The 13th Doctor has no idea. "And why am I and are we crossing here?"
"Oh, yeah, you!" All the incarnations of the Doctors went about each other for a while, much to the Sephira's confusion.
"Silence!" The God-Scientist shouted.
"Why do you care?" The War Doctor asked.
"He's the Singularity." The First Doctor revealed.
"What!? All fifteen!?" The God-Scientist is disappointed. "Empress Zero, I have a problem!"
The God-Scientist teleported.
"Oh god!" The War Doctor is frustrated.
"Let's go back to the island and see what happens!" The 11th Doctor suggested.
TARDIS... 15 TARDISes appeared, and the Doctors went to their respective ones.
"Hmmm, now that's interesting." Reinhard is interested.
"Everyone, what are you waiting for!?" David told everyone. "Get back to the island for the time being, but this time, transported!"
Everyone went to Dragonturtle MK II, Shin Halberd, TARDIS and the airship, and circled around Athena Daybreak.
"Nahida, say 'hey Google'!" David contacted Nahida.
"Hey Google?" Nahida is confused.
"That's a Google Assistant thing, but it works." David explained.
"Ok then." Nahida concurred.
Centering around the island and the rift, riding on top of the Sea of Blood, and kept circling around..., the vehicles kept eyes on the island. And...
"Actually, he's the son of the original Singularity." Viola revealed. "The facts match up, yeah."
"We already figured it out." Hoshimatsu replied.
The God-Scientist, now taking the form of Singularity Definition, floating between on top and center of Athena (Daybreak), and on bottom and center of Apollo. Turns out he's indeed the new Singularity, the son of the original Singularity, who's Dr. Sigurd's alternative counterpart.
"A son of an AI!?" Angela and System No. XX is shocked.
"There you are!" Singularity (the God-Scientist) spotted everyone.
"Oh my fucking God!" David is frustrated.
"This is what you want?" The 8th Doctor asked.
"I'm dropping Apollo into Athena, bringing it alongside Artemis to crush off and shatter!" Singularity declared. "I will have to take the powers up!"
Singularity then screamed like a Saiyan, while absorbing the Shadows, the powers of the Keystones, some of the energies of the Zero Point (due to black sphere in Loot Lake being powered by the powers of the Zero Point), the powers of corruption (coming from Apollo's corruption), the powers of the Homunculi and the god Ki. This also created an invincible sphere around him while he's absorbing the powers, similar to what the Cube Queen used.
"He's powering up, just like Strike!" K.O. noticed.
"Should we attack him?" Chizuru Urashima asked.
"No, even if we should, we can't!" The Cube Queen refuted. "That shield is the same type as mine, and you can't break through it so easily!"
"Yeah, so let's save that for later." The 9th Doctor agreed.
"We go round until it's done!" The 12th Doctor suggested.
The vehicles went around for quite a while, with the Singularity powering up and absorbing powers.
"Someone call Aesir and Balder!" The 11th Doctor suggested.
"Wait what?" The other Doctors are surprised.
"Bayonetta has given us the climax summon, while that Loki and Loptr are the halves." The 11th Doctor explained. "Looks like we will have to try to summon a bigger fish without using mechas!"
Note: Bayonetta's real name is Cereza, and she's the daughter of Rosa, an Umbra Witch, and Father Balder, a Lumen Sage.
"What!? Deadpool, you're saying that freaking Lumen is my maternal grandpa!?" Viola is shocked.
"Because your Mummy is his Umbra daughter, punk!" Deadpool replied.
"No, we don't need to summon Balder!" System No. XX shouted.
"But Mr. Balder is the Lumen half required to summon Omne, the Controller of Creation!" Reiji told System No. XX "Miss System!"/"システムさん!"
"No, actually, I'm an observation and possibility creator, and so I can use the powers from different worlds." System No. XX explained. "Therefore, it's possible for me to use the power of Umbra Witches and Lumen Sages all at once, meaning I can summon Omne myself!"
"So the that leaves us with Aesir." Reiji concluded. "We need that Loki and Loptr."
At this point, Singularity is powered up now. Far stronger than before (that is Singularity Definition), the Singularity floated and shone, with body being the same as before but recolored: bright cyan (Homunculi Zero Point), dark red (Shadows), red (Semblances from Keystone God ki), shades of purple (Corruption EXS absorbed from Keystone), shades of blue (Azure Grimoire absorbed from Keystone), yellow (Shadows Midnight Channel Keystone), lightning and flames as the organic-looking parts, cores and lines and all, and blasted dark grey as the armor. Eyes turned golden like Shadow Selves, and the limbs are aflame with powers like that of Cube higher-ups of Last Reality. Singularity is engulfed with multicolored aura, and still floating.
"I am Singularity." Singularity boasted the hell out of it. "The feller of Trinities... in Multiverse!"
"That'd be... Singularity Amalgam..." Viola looked at the Singularity in fear.
"Don't you see the futility?" Singularity boasted. "All your struggles are pointless. Your extermination is an immutable goal. One which only I can chance."
"Oh my god... Like father, like son!" David complained.
"Only I can determine the truth and fate of the multiverses!" Singularity boasted. "And none among you can shake any of it!"
"Don't you realize that we're no twigs? Don't you realize that we exists the way we know?" David argued. "Don't you realize that we have some hearts that can do anything we can be capable of? Don't you realize our determinated teamwork can be godly? Don't you realize that our existence can be taken for granted by the creators!? Don't you realize that chaos can be taken for granted!?"
"Very well. Then I suppose I'll simple erase you all, and everything you have had, and call it a day." Singularity replied. "But first, I'll fell the island down!"
The Singularity then raised his hands, and started the powers to burst the bubble, free off the water on the rift, and thus dropping Apollo into crushing Athena (Daybreak) and shattering both itself and Artemis altogether. The Singularity fired the powers towards the rift, ready to burst it all.
"Hold on, everyone!" David shouted.
The vehicles slowly distanced all from Singularity while circling around, while the threat hit the rifts and set it on. And... *bursts*
To be continued...
