Fanfic / Oscura's Encore the Movie: Return to the Boiling Isles

Oscura's Encore the Movie: Return to the Boiling Isles is a Fusion Fic between The Owl House and Kamen Rider, specifically Kamen Rider Geats, co-written by Dr. Exposition and Michael Ravencroft.

The latest round of the Desire Grand Prix sends the four remaining Riders for the round (Luz Noceda/Kamen Rider Oscura, Amity Blight/Kamen Rider Gato, Sasha Waybright/Kamen Rider Soaron, and Marcy Wu/Kamen Rider Newtonne) to the Boiling Isles. Given their past in this world, Luz and Amity are naturally nervous to return and want to get out as soon as they can. Unfortunately, not only is there now a cult dedicated to worshipping Luz's past identity as Empress Oscura, former Head Witch Terra Snapdragon manages to abduct a Jyamato to use to enhance her magic. Can the Riders put a stop to these threats to the Boiling Isles?

The fic, part of the Disney Riders series, can be read on Archive of Our Own here and on FanFiction.Net here.

Oscura's Encore the Movie: Return to the Boiling Isles contains examples of:

• Adaptational Villainy: Bria was more of a bully who was far from a threat in canon, but in this fic, she's the leader of a cult dedicated to worshipping Oscura.
• Big Bad Duumvirate: The fic estsblishes two different villains responding to Oscura's return. Bria, who leads a cult dedicated to worshipping Oscura, and Terra, who managed to capture a Pawn Jyamato and plans to use it to enhance her magic.
• Big Damn Reunion: Luz reunites with Eda and King after four years, while Amity reunites with her father and older siblings.
• Boisterous Weakling: Despite the punk look, Lumina says that Amara actually has no idea how to break free from her family's influence and be independent.
• Canon Character All Along: After a lot of ambiguity surrounding his identity, this fic finally confirms that the King of Amphibia and Marcy’s supporter is King Andrias.
• Cheerful Child: Eda and Raine’s daughter, Little Luz, is this.
• Christmas Episode: An In-Universe example with the DGP. The Jyamato the Riders fight for this round are themed after Santa’s elves.
• Cutting the Knot: Because she doesn't want to have to explain everything they've been through to them after they just recapped their adventures to Eda and King, Sasha makes Gus and Willow touch her ID Core so they'll automatically remember their time in the DGP.
• Evil Cannot Comprehend Good: In the narration, Woz, a former follower of Oma Zi-O, fails to see the problem with Luz getting a cult of worshippers in the form of the Children of Oscura.
• Four-Temperament Ensemble: The four remaining Riders featured in this fic are this.
  • Luz/Kamen Rider Oscura: Melancholic
  • Amity/Kamen Rider Gato: Phlegmatic
  • Sasha/Kamen Rider Soaron: Choleric
  • Marcy/Kamen Rider Newtonne: Sanguine
• Heroic BSoD: Luz discovers she can do glyphs again after four years. When Amity sees this, at first she’s proud for Luz but then she thinks back to that duel with Luz four years ago. And like that, the full weight of what she had done to Luz drops down on her like a ton of bricks and Amity has a full on breakdown. Amity is in so much despair she even says she doesn’t deserve someone as loving as Luz. Thankfully Luz is there to help pull Amity back from the brink.
• Hotter and Sexier: This fic features several sex scenes, though the reader has an option to read a version without them on FanFiction.Net.
• How the Mighty Have Fallen: Terra Snapdragon and Adrien Graye. Once two of Belos’ top underlings as heads of the Plant and Pllusion Covens, respected and feared. Now? Stuck living together in a small apartment, hardly even tolerated, and can’t even hold down jobs as elementary school level or even kindergarten teachers ever since the coven system was abolished.
• If Only You Knew: As the characters are eating dinner and theorizing just how the DGP grants wishes, Sasha suggests the idea of them using a god to grant wishes, which viewers of Kamen Rider Geats will know is the correct answer. Tsumuri, the only DGP staff member in the room, nearly chokes on her food when she hears this, but says nothing else.
• Mass "Oh, Crap!": The Coven Scouts working for the “United Covens of the Boiling Isles” panic when they see Oscura has returned.
• Nice Job Breaking It, Hero: A rather literal example occurs when Luz accidentally steps on Tsumuri’s tablet, the one thing capable of contacting the DGP and getting them out of the Demon Realm. Of course, Luz also accidentally draws a lot of attention to her team when she transforms using the Oscura Buckle, even though she meant to transform using the Fantasy Buckle.
• Nightmare Fetishist: While Sasha is horrified to learn that the Boiling Isles is a giant corpse, Marcy is far more interested in learning about the Demon Realm.
• O.O.C. Is Serious Business: Tsumuri begins uncharacteristically panicking when her tablet is broken.
• Oh, Crap!: Luz has this reaction when she realizes the DGP sent her and the others to the Boiling Isles after her exile.
• Our Demons Are Different: Discussed. When told the Boiling Isles is home to all sorts of demons, Sasha assumes the demons in question are “Goat-horned creatures with pitchforks or any of those succubus or incubus things”. Luz responds by explaining that the Boiling Isles is home to all sorts of demons, though Amity chimes in by claiming that succubi and incubi aren’t real... Although Krampus is.
• Power Perversion Potential: When Luz and Amity have sex, Amity uses her Abomination goo to spice up their lovemaking session.
• Relationship-Salvaging Disaster: Because Tsumuri's tablet was broken, Lumina and Amara were forced to travel to the Boiling Isles to help the DGP Riders. This gives Luz and Amity the chance to talk to their Supporters and help them work through their issues and become a couple again.
• Religion of Evil: Oscura has a cult of worshippers who believe she is still the rightful ruler of the Boiling Isles.
• The Reveal: King Andrias isn't just Marcy's Supporter. He also chose Anne and Sasha as participants for the DGP.
• Right Through the Wall: Tsumuri struggled to sleep at the Blight Manor thanks to the loud noises of the two couples (Lumuty and Sasharcy) having sex at night.
  Tsumuri: If I may be honest, the source of my sleep depravity was more due to the noise.
  (Luz and Amity gulp)
  Luz: W-What noise exactly?
  Tsumuri: Hmm, let me see. There was certainly a lot of screaming and moaning, the constant squeaking of bedsprings, and of course, the rather vulgar language used such as, ahem, "Fuck me harder, Amity!!!" and "You want me to fill you up?!".
• Shipper on Deck: Luz and Amity help Lumina and Amara realize they still love each other in order to get back together.
• Winds of Destiny, Change!: Lumina and Amara's Kamen Rider forms have this ability, with Lumina's "Curse" focusing on creating bad luck for her enemies and Amara's "Charm" focusing on creating good luck for herself.
