AN: Hi so it brings me to tears to announce Kamen Rider Kaseki ending. Internal conflict between myself and others have caused it to be unable to continue. But I can't let it just go unended so here's a summary of the rest of the story. I just want to thank everyone for reading and their support. This isn't the end though as there's maybe a teaser at the end that shows what's coming next. One last time thank you all for everything and have a good day.

Kamen Rider Kaseki

What Remains Summary

Shortly after Riku gains his final form, it's Kenta's birthday and he's naturally excited but he begins to have doubts because he's not gaining strength like Riku has been.

Meanwhile Riku and Daigo are testing a new ice based Dimago failing miserably. Daigo leaves to warm up and Riku reveals to Alfie he hasn't tried Kenta yet because Kenta has a weird 1/4 of his DNA one that's not human.

The girls go out shopping to get Christmas presents and Chiyo struggles on what to get Kenta since they're now dating. In the end Kenta overcomes his doubts becomes Ptera-R Glacial and Him and Kaseki defeat the twin Metoryu.

Later they celebrate Christmas and Kenta's birthday and Chiyo gives Kenta sex for his birthday. Next skipping ahead a month or two the generals decide to unleash a memory erasing Metoryu which accidentally hits Paravler and Stegronze taking the opportunity to get rid of her abandons her in the streets.

The riders also get their memories erased. Eventually Paravler is found by Mikio and his family and they treat her nicely and the kids bond with her.

Eventually she gets her memories back but understands humans a bit more and Rika ends up saving the day with Riku giving Rika the Dimago yielded from the Metoryu, the amber Dimago. One day Kenta takes the others to the orphanage he grew up in after his parents' deaths.

They the caretakers and their friend Takumi Inui, Kamen Rider Faiz. A plot from Elemental Sphere causes them to team up and Elemental Sphere ends up having all they need to create their own rider.

Daigo bonds more with his daughter and mans up and meets his baby mama all while talking with Riku about how he believes in people.

The riders meet a Metoryu that they can not defeat and when they're about to be killed they are saved by Kai Kino who reveals himself to be the Metoryu's leader, Kaijold who angry that the Metoryu nearly killed Kaseki which he doesn't want he snaps his fingers destroying the powerful Metoryu with ease angering Riku.

Kaijold explains who he is and leaves reprimanding Stegronze who is become an increasing liability to his plans. Riku becomes obsessed with defeating Kaijold and in the end going to confront him Kaijold asks Riku to join him citing both of their contempts for humanity.

Riku rejects Kaijold and Kaijold not worried decides that his friends need to die for Riku to join him. He sends Stegronze after Daigo reasoning no matter who dies it benefits him.

Diago manages to kill Stegronze after a fierce battle and Pachyphite deals the final blow to him taking his place as a general. Kenta meets his grandfather who is a Metoryu who's a similar Dinosaur to Paravler and Kenta has an identity crisis after learning he's ¼ Metoryu and Paravler is his aunt.

Riku is horrified at learning some Metoryu can have offspring. Riku goes to search for a stronger power to defeat all the Metoryu and Rika not wanting to be left to do nothing starts to get involved more directly in fights.

Eventually during a fight where Kenta and Daigo defeat Pachyphite, the general uses all the energy he has stored to detonate hoping to kill Rika, Daigo takes the blast for her and dies surrounded by the cast including a returned Riku who had been given a purple Dimago by Kaijold.

A week after Daigo's death a Metoryu emerges that if not destroyed within a time limit will destroy the city with its powers from uranium. Riku is clearly affected by Daigo's death but refuses to admit it.

Rika yells at him about how devoted Daigo was to him and how he doesn't seem to care. Riku breaks down because he's upset that he realized too late that he cared about Daigo and he would forever regret not treating him better.

Rika tells Riku it's ok to be sad and have regrets but Daigo knew Riku did care about him. Riku takes off purple Dimago in hand. He arrives to fight the Metoryu and declares that Daigo Umi was his best friend and for him he would protect the humanity he loved so much.

Declaring himself Kamen Rider Kaseki he transforms into his final form Mesozoic and destroys the Metoryu with ease. Kaijold appears amused by these events and congratulates Riku.

He reveals his monster form looking like Mesozoic and reveals he had dedicated 500 years of his life bringing people together, getting them to have children all the way down to Riku, so he would have someone who has similar DNA to him also revealing he is the ancestor of humanity.

Riku is not deterred by Kaijold revealing he was behind his birth and they fight briefly evenly matched. Kaijold is still amused about the turn of events and vows to kill everyone Riku cares about before leaving. Rika meanwhile blames herself for Daigo's death and begins to become depressed. Eventually she is gotten out of it by Daigo's spirit asking her to take over for him.

Taking his driver Rika uses the amber Dimago to become Kamen Rider Amber which doesn't make Riku happy. The tension grows between them due to Riku becoming overprotective and eventually Rika calls him out.

Resulting in him admitting his feelings for her and the two starting a relationship much to the relief of everyone in the manor. Later after bonding with his grandfather and learning how Paravler when young was rejected by humanity Kenta is forced to watch his grandfather be killed by the returned Pachyphite now called Pachymond.

Kenta in anger at seeing two people he cared about were killed by this creature uses the Dimago from his Grandfather and become Ptera-R Rakurai and kills Pachymond once and for all.

Meanwhile Kaijold becomes more angry at seeing Riku and the others grow in power causing Paravler to fear as she's the last general alive. Later Mikio asks a respected detective Shotaro Hidari and his partner Philip for help with a case involving a Metoryu using a Gaia memory.

Kaseki and Kamen Rider Double team up and Mikio takes on the mantle of Kamen Rider Skull from his and Shotaro's shared mentor. Mikio tries to appeal to Paravler as the two have an attraction to each other.

Eventually it is revealed that Mikio's father is the one who while on an assignment for the global police in England ran over and killed Riku's younger brother haunting him and eventually driving him to suicide infront of a young Mikio causing him to forever remember the Hitsu family.

Riku not the humanity hating man he once was forgives Mikio and his father and Mikio finally finds out who Kaseki is joins the group. Daigo's daughter who worked for the now destroyed organization Elemental Sphere becomes the new version of the movie rider Kamen Rider Relic looking like a purified version.

Kaijold reveals to Paravler how he once ruled the world when humanity was young and his son the original Kamen Rider Kaseki fought back and while he did not kill him did cause him to no longer be able to reproduce resulting in the plan that eventually caused the birth of Riku.

In a battle against Amber and Ptera-R, Paravler is finally convinced to join the heroes and she turns against Kaijold and she reveals where the Metoryu's castle is. Kaijold's plan is revealed that he wants to cull all of humanity and start anew in the Jurassic times so he can once again rule the earth but he is not strong enough to do it alone so he needs Riku to aid him.

The riders storm the Metoryu castle taking out most of the remaining Metoryu and trying to stop Kaijold who has fled with the machine that will harness his and Riku's energies to begin his plan.

The endgame begins as Riku tries to contact all the people he has met including Kamen Rider Ichigo as the riders race to find an ever increasingly unhinged Kaijold. However what they don't realize is Kaijold is at Hitsu Manor and he destroys it and kills Alfie, killing the last person that connects Riku to his pre Kaseki life.

Riku finds Alfie's body and becomes enraged after he is forced to explain to Alfie's 5 year old granddaughter what happened to her Grandfather. Riku is enraged and goes to confront Kaijold but it ends up being a trap and Riku is restrained to the machine and the culling begins.

Anyone with enough DNA from Kaijold is being turned into a Glasseroid around the world. Riders gather around the world to fight the threat and Ptera-R and Amber fight to free Kaseki. Amber using Daigo's Dimago to become Amber Tempest frees Kaseki and he and Kaijold begin their final battle.

The battle is long and destructive and it ends with an untransformed Riku and Kaijold fighting weakly with their fists. Riku not willing to give up kills Kaijold with an unhenshined rider kick ending his threat forever.

Though the world is slightly scared by what happened over all the world is saved. And Kenta excited at having saved the world proposes to Chiyo. Later Riku, Rika, Kenta and Chiyo have moved to Hawaii as Daigo once dreamed.

Recognizing he now has a fresh start, Riku says goodbye to Daigo throwing his sunglasses into the sea and goes to begin his new life with the ones he found on his journey to become a Kamen Rider.

The End

After Credits

Paravler walks the streets, now living with the Ota family and having been stripped of her powers by Kaijold. As she walks a group of remaining Metoryu appear threatening her.

Paravler: Do you know who I am you insolent creatures

The Metoryu look at her knowing she's lost her power and they ready to attack her but suddenly they are knocked down by a passing motorcycle with the driver calling to the monsters

?: You know it's not very nice to attack a helpless woman

Paravler looks at the man confused at who he is but before he can introduce himself he looks to the side and begins talking to himself

?: No I'm not saying that, because it's rude, yes I know she's pretty but still, Apollo you can't say those things now a days.

Paravler looks at the man confused talking to himself before he finally noticed the monsters getting ready to attack again and turned to face them

?: Oh right these guys my bad *Quickly he takes out a belt and an orb* Well then let's start this battle

He places the belt on his waist and took out the orb placing it in front of the driver. At this point Paravler could see what appeared to be a ghost of a blonde haired man appeared behind the man.

?: Apollo lend me your power

The being Paravler could guess was Apollo responded to him

Apollo: Let's Go Partner!

The orb still placed in front of the driver began to speak

Driver: Apollo Orb! *Apollo now fully scene appeared out of the orb*

The belt began to chant

What's beyond the chains?! Break freeeee!

What's beyond the chains?! Break freeeee!

The man looked to almost be praying with Apollo mimicking the pose before he yelled

?: Henshin

He pulled the slide as he was enveloped in a golden light forming armor around him as the belt almost sand

Ride on! Power of the sun! (The golden god!) Apollo Frameeeee! Yeah!

Finishing the henshin he was hit by a Chariot leaving him with armor completing the henshin.

Paravler looked at him in astonishment

Paravler: Who are you?

The man laughed a bit and dusted his hands getting ready to fight

?: The names Kamen Rider Mythos and now let's give the gods a sacrifice

With that the new Kamen Rider charged at the Metoryu as all could be seen from above the streets was a gold light shining on a new story.
