Spoilers from included and/or represented works abound. Please read this fiction carefully.
Fighting for Rosalina, a group is bombarding Cursa, who fused with Rosalina now, through the power of Sparks. They dodged what it thrown into and focused on bringing the Sparks.
Saber, in particular, summoned copies of Seikens and Rider Swords to pick up the brilliance.
"Everyone, act with the projections and don't get hit!" Edge the Rabbid wielding the Flying Blade, also named 'EDGE'.
The blade flew over and cut off the Darkmess Tentacles and further activated the projections. One such tentacle, however, is about to stab Edge.
"Damn it!" Edge the Rabbid is about to be impaled.
System No. XX catches the tentacle with simply Waldstein's gauntlet, saving Edge the Rabbid.
"Darkmess incarnate, you think?" System No. XX crushed the tentacle.
"Die!" Rosalina/Cursa, now referred to as 'Dark Rosalina', summoned a dark meteor rain towards System and Edge.
"Dodge!" Beep-O and Jeanie shouted.
System No. XX summoned copies of the Investigation Team's Personas and then brought Edge the Rabbid out. The Meteor destroyed the Personas.
"Rabbid Rosalina! Shoot the projections!" Princess Peach told Rabbid Rosalina.
Rabbid Rosalina conceded and rapidly shot some projections, charging them even further. However...
"Argh! Why those nasty tentacles!" Rabbid Rosalina got caught in Darkmess Tentacles.
"Rabbid!" Zenkaiser approached Rabbid Rosalina.
A tentacle tripped Zenkaiser, causing him to fall out.
"You shall be stripped of all hope and existence!" Dark Rosalina is about to kill Rabbid Rosalina.
"No!!!" Rabbid Rosalina cried.
System No. XX summoned Ruby's Crescent Rose as a scythe, and slid through.
"Leave her alone!" System No. XX cut off the tentacles, saving Rabbid Rosalina.
"Wow, thanks!" Rabbid Rosalina thanked System No. XX. "You're so cool!"
"Look at who I brought!" Zanger appeared alongside a woman.
"Zanger Sanvolt!" System No. XX noticed. "She is..."
She is an energetic, spontaneous girl. She has light-pinkish hair, wearing a cool shade, and is an investigator for the Galactic Space Police Brotherhood. She's wielding a bass guitar.
"Haruko Haruhara!"/"ハルハラ・ハル子!" System No. XX noticed. "And a yellow Vespa SS 180!"
"Hello, System-san!" She greeted the System. "Haruha Raharu!"/"ハルハ・ラハル!"
"Actually, she is Haruko Haruhara and Julia Jinyu in one, and Angela summoned her, by the way." Sanger explained.
"That was unexpected." Dark Rosalina is confused.
"You see those projections with Rosalina's powers?" System No. XX told Raharu. "Cross All. And charge them all."
Raharu went through it, and played a bass with her guitar, quickly charging all the projections at once.
"Cross All!"
As a result, more and more Sparks fell into the projections, charging the projections at a exponentially increasing rate, assisted even further by Raharu playing. This play also...
"Uh... Gh... Gah... Ugh...!" System No. XX has N.O. manifesting in her.
Cross-trivia: N.O.is the power to mentally call other objects and energies through light years of space. It calls upon both sides of the user's brain's thought processing abilities to open channels through multiple dimensions to instantaneously pull things through. N.O. may be a metaphor for opening the mind.
A N.O. portal appeared in System's head, revealing a Rift Beacon, which fired upwards, piercing through Cursa's galactic body and summoning a portal far larger than galaxies.
"How!?" Dark Rosalina is angry.
"N.O. plus Sparks equals..." Zanger declared.
Several colossal swarms of Sparks then went inside Cursa and charged the projections.
"We call it... The 'Sparks of Hope'!" Zanger called it.
All Sparks near-instantaneously charged the projections. The Rift Beacon disappeared and N.O. closed, leaving System No. XX briefly fuzzy. "Uh... So much!"
"How many!? How much!?" Dark Rosalina cried.
"Rosalina, we told you that we'll save you." Edge the Rabbid told Dark Rosalina.
"Yeah! And we Sparks Hunters has since realized the folly!" Midnite, Bedrock and Daphne appeared alongside Edge.
"How could you, the Spark Hunters!?" Dark Rosalina is enraged.
"Huh, Cursa is nothing but a shitload." System No. XX recovered and took Rosalina's wand she summoned.
"It's over, Cursa!" Edge the Rabbid said. "This is the true end of your Spark-genocide!"
System No. XX inserts the wand into Raharu's guitar.
"Strum your bass hard!" System No. XX told Raharu.
"Bats. We calls those so-called guitars 'bats'." Raharu corrected.
"That's it!" Dark Rosalina then summoned Darkmess Tentacles under the over-charged projections, then absorbed the powers to get stronger.
"Not so fast!" The Hegemonies teleported and held the projections and together.
Mitra and Kouha held the first, Magsarion and Satanel held the second, Mercurius and Reinhard held the third, Hegemony Marie and Ren Fuji (as Tenma Yato) held the fourth, Hajun and Hirume held the fifth, and the Yatsukahagi and Yomi held the last.
"We emanate the laws, you do the ignition!" Ren Fuji told Raharu.
"Impossible!!!" Dark Rosalina cried.
"Not anymore!" Mario and Luigi argued with Dark Rosalina. "Everyone Cross All!"
The Hegemonies and friends chanted the emanations, and thus released their full powers the same time as Raharu strum out, all convinced with Cross All, igniting the projections altogether.
"Nooooo!!!!!!!!!!" Cursa screamed.
The explosion of Sparks' lights and powers and energies blasted Cursa altogether, resulting in a explosion that obliterated the universe is currently in, depicted as an exceedingly blindly bright flash engulfing the said universe.
The alliance in the Library celebrated.
"They did it!" The alliance celebrated.
"Yay! Good girl did it!" Ruby celebrated.
"Finally!" The In-Births celebrated.
"Success! Cursa is truly no more!" Beep-O and Jeanie celebrated. "The Darkmess isn't just dormant anymore, it's finally inactive for good!"
"They did it!!!" Saya then hugged her brothers.
"I'm proud of you, this violent System." Rachel saw the victory.
In that evening...
"Good girl, you did a good job!" Ruby complimented System No. XX.
"Ruby Rose, please thank the heroes, Haruko, Mario and friends, the Hegemony Gods and the Rabbids too." System No. XX told Ruby. "They helped me destroy Cursa and save Rosalina."
"And good thing us Spark Hunters has reformed." Edge the Rabbid commented.
giggles* "We sent regards to your participants as well." Midnite told System No. XX.
"Wait what?" System No. XX blushed. "You... mean the Keystone Scramble Tournaments?"
"We joined the alliance together, and we're looking forward to helping save the reality." Edge the Rabbid reported. "Trust us."
"Another client incoming!" Malkuth rushed, crashing into Bedrock. "Oops, sorry! But I gotta go!" *runs away*
"Is this one of the Patron Librarians?" Daphne asked.
"Ask Angelica." System No. XX. "She knows basically everything about this Library."
"Just Angela." Edge the Rabbid tried to correct System No. XX.
"Actually, her full name is basically Angelica, according to the datas." System No. XX corrected Edge the Rabbid.
"Call Angela whatever you want." The Spark Hunters then left to ask Angela.
Moments later...
"Hello? Can I rent a room?" An injured girl appears before Angela.
"Welcome to the Library of Ruina." Angela greeted the girl. "Who are you?"
"My name is Sakagami Ayumi." The girl introduced herself. "Recently, a girl named Ikue Higashi just betrayed me."
Angela is secretly shocked at Ayumi's report.
"Isn't she Cure Echo of Pretty Cure, betrayed by that Ikue Higashi, the non-existent Cure Union?" Angela thought.
"Ok, Cure Echo. Please take a seat." Angela offered Ayumi a seat.
"Huh!? You know my identity!?" Ayumi realized that Angela knows her Cure identity.
"Sit and talk." Angela responded.
Angela and Ayumi talked for a while. Ayumi learned that Ikue is actually a suspect, and may or may not actually exist as herself.
"Excuse us, what are Patrol Librarians?" The Spark Hunters asked Angela.
"It's 'Patron Librarians', not 'Patrol Librarians'." Angela corrected. "The Patron Librarians are the main librarians of the Floors of the original Library, being the ones who sort the Books obtained through the Receptions. There is one unique Patron Librarian for each Floor."
"Please refer to the Sephirot tree list shaped guide for more." Angela gave the Spark Hunters a guide.
"Ok. I'll go visit them." Edge the Rabbid took the guide.
The Spark Hunters left to visit the Sephirot, each Sephira.
"Ikue Higashi is suspicious?" Ayumi asked back. "Hence why she betrayed me?"
"We're finding how she came to be, as well as what's inside such situation." Angela concluded.
Meanwhile, at Shinra HQ...
"Rosalina! We're glad you're back!" Hirume told Rosalina. "Hehehe...!"
"Miss Rosalina, welcome to the alliance." Reiji welcomed Rosalina. "I am Reiji Arisu, an agent of Shinra."
"It's me, Xiaomu of Shinra!" Xiaomu introduces herself.
"It's Shinra of Cross, not Shinra Industries." Cloud Strife clarified.
"Known that you've saved the Rabbids and Mushroom Kingdom, and they gave the favor back by killing Cursa off." Reiji discussed.
"I sincerely thanks Mario and friends for saving me from that." Rosalina replied. "It's a pleasure to be given the privilege."
"It's our mission to keep the appropriate dimensions in control." Xiaomu said. "That's the spirit of Shinra!"
"Ok, so I am considered a Warrior of Light." Cloud discussed about his place. "There's others that seemed to have been given such titles."
"Come to think about it, well... the other Champions can relate." Reiji discussed.
"We want to ask Materia or Cosmos, but where are they?" Cloud asked.
"Shin Halberd has been reconstructed from the ground up!" Frieza reported. "Now we can transport so much!"
"Wow! Dragonturtle MK. II, Super Galaxy Dai-Gurren and Shin Halberd, all capable!" Xiaomu exclaimed.
"So what's the plans?" Cloud asked.
"Another news is about Ikue Higashi, who recently betrayed Sakagami Ayumi for some unknown... reasons." Frieza continued. "Lobotomy's Angela gave the news."
"Two cases now?" Cloud noticed.
"Anyways, bye!" Frieza then flew away.
"Let's get into both soon." Reiji told everyone.
"Cases incoming!" Xiaomu responded.
"I bless you upon stars." Rosalina wished for.
"Should we forget that Sparks is fusions of Rabbids and Lumas?" Xiaomu asked.
"Ask the Spark Hunters." Reiji replied.
"Wait a second..." Reiji realized something. "There was a rumor?"
"Huh? What's wrong?" Xiaomu wondered.
"Some strange rumor someone's talking about..." Reiji considered something.
"Oh, I kinda know what's going on." Cloud replied. "I'll let's you see it." *shows Mate 50 Pro*
A TikTok video is played. "Duuuude! You know what's crazy!? You actually get... to watch Midnight Channel! Yeah, it's real! Midnight Channel will return to air to the omniverse!!!"
"What!?" Reiji and Xiaomu are shocked.
"So these are the rumor you're thinking about." Cloud responded.
"Unbelievable...!" Rosalina is shocked.
"And just recently, the video I shown to you guys are now viral across several worlds." Cloud continued.
Cloud then replayed the same video.
"So these are the rumor..." Reiji replied. "We'll keep an eye on this."
"Good luck, mates." Cloud then walked away.
"This is getting complicated..." Xiaomu quietly complained.
Nighttime...
"The Library is closed." Carmen compacted and collapsed the Library, putting it into light for Carmen. "It's time to go home."
Carmen, Angela, Ayin, Roland, the Sephirot and Raiden went back to District 12, the place where Lobotomy Corporation was. Now dubbed themselves as Team Lobotomy-Ruina, the group sheltered in the ruins, and coincidentally found a working cathode-ray-tube television. They also found David and Rebecca.
"Um... why are you lugging that CRT-TV around?" Hod asked.
"We're scavenging it." David replied. "Even though it's still working."
"I'm tired..." Rebecca is tired.
"It's nighttime, and we're quite fed up with the day." Netzach commented.
"Let's shelter in." Carmen suggested.
Everyone went to the shelter, and put the CRT-TV inside.
"Sorry, but I couldn't turn it off." David told the Lobotomy-Ruina.
"This seems like a late CRT-TV." Hokma observed. "It appears to have been made in the turn of the millennium."
"Year 2000?" David asked.
"Likely. However, somehow, it's turned on and stayed so ever since the noon." Hokma suspected.
"Let's have a dinner." Angela told everyone.
While waiting for the CRT-TV, David, Rebecca and Team Lobotomy-Ruina had a dinner. A couple of hours after the dinner, it's 11 P.M.
"So far, so static." David noticed.
And then...

"What's on the omniverse is that!?" Those who watched the commercial are all shocked.
