Story
Skull: Message for W

Akiko finds herself in the past, witnessing her father Sokichi Narumi during a case regarding an opera singer named Melissa and a stalker called the "Spider-man." Heading to city hall for Melissa's performance, with a young Shotaro Hidari among the audience, Sokichi meets Melissa's seedy manager Kozo Yaguchi before Melissa's stalker, the Spider Dopant, appears and attacks the police. Sokichi fights the criminal before a Gaia Memory dealer named Eren Komori appears and the two take their leave. Though his partner Seiichiro "Matsu" Matsui suggests to leave it to the cops, Sokichi returns to the detective agency to meet his benefactor Shroud, who reveals that the Museum has begun their master plan and tries to give him the Skull Memory which he turns down. He later meets with Matsu at the library after Yaguchi's previous female clients are among the missing persons.
Finding help in an informant named Stone, Sokichi breaks into the Yaguchi Talent Agency where he finds the missing girls being used as test subjects in Gaia Memory research. Forced to watch Stone get killed by Eren Komori when she becomes the Bat Dopant, Sokichi is unable to escape from her and the Spider Dopant. But Shroud arrives and tosses him the Lost Driver and the Skull Memory, allowing him to become the incomplete Kamen Rider Skull Crystal as he proceeds to defeat several Masquerade Dopants before getting himself into a pinch. Receiving a call from his young daughter Akiko, Sokichi promises her that he will attend her wedding when she grows up. This gives him the drive to fight as he pursues the Dopants. He only finds Yaguchi, who was only supplying the Museum with test subjects before he is killed by a Spider Bomb concealed in his wife. The next day, Sokichi confronts Matsu, knowing that he is the Spider Dopant after recognizing his handwriting at the scene of the crime. Found out, Matsu tries to fend himself from Sokichi before Melissa reveals that Matsu took the Gaia Memory to protect her from Yaguchi before it warped his mind. Furthermore, Matsu has placed a bomb in Melissa so she can love no one else. But the fact she does not love him drives Matsu further into insanity as he assumes his Dopant form and blankets Sokichi and all of Futo with Spider Bombs.
Having no choice, Sokichi attempts to chase his ex-partner down. However, the Bat Dopant gets in his way as Sokichi becomes the complete Kamen Rider Skull. He chases after the Spider Dopant while using the SkullGarry to deal with the Bat Dopant before taking her down her with the Skull Punisher. Though she begs Kamen Rider Skull for mercy, he leaves her to die in the vehicle's resulting explosion. Catching up to his ex-partner, Kamen Rider Skull explains that Matsu is now paying for his crime and the Dopant must now follow. Using a Rider Kick, the Spider Memory breaks with Matsu dying in the Memory's side effects. Leaving a heart-broken Melissa without a word, Sokichi takes his leave.
In the present day, Akiko is horrified at the tragedy she saw as the Pteranodon Yummy now has the ideal memory of a intense battle needed to achieve his goal.
OOO: Nobunaga's Desire


First appearance of Kamen Rider Birth
Heartbroken, Eiji becomes Kamen Rider OOO to fight him while Yoshino is confronted by a Greeed named Giru who uses her to create a female Pteranodon Yummy that meddles in the fight before it is destroyed by Kamen Rider OOO Gatakiriba Combo. However, Nobunaga begins to suffer a total Cell Medal breakdown to the point of losing his memories. He demands how Eiji can enjoy life without desire, only to find the answer he receives both foolish yet sensible. Nobunaga finds Yoshino at the hospital, using the last of his power to heal her leg. However, Doctor Maki arrives and adds three black Core Medals (Sasori, Ebi, and Kani) into Nobunaga which causes him to assume his complete Greeed-like form as he pleads Eiji to kill him. Having no choice, Kamen Rider OOO battles the Greeed and assumes Sagohzo Combo to end his friend's misery. Nobunaga thanks Eiji for opening his eyes to what truly matters in life as he asks Eiji to give Yoshino his regards before he breaks down into Cell Medals. The three black Core Medals fly off with Eiji in pursuit.
Movie War Core

Continuity and Placement
- Kamen Rider W: It takes place sometime after Philip was revived.
- Kamen Rider OOO: The movie contains many factors that generally make it impossible to reconcile its events with the series' continuity. The greatest of these is the usage of Kamen Rider Birth: while Nobunaga's usage of the belt is context-free, Shintaro Goto is Birth here; whereas in the series he is initially passed over by Kougami in favor of someone else. Likewise, Eiji and Ankh possess the latter's medals; these are fully obtained only after the defeat of Mezool and Gamel, both of whom appear in this movie and who don't return until after Eiji receives an even stronger form. On top of that, the existence of Giru, the Dinosaur Greeed (and thus the Pteranodon Yummies), is completely impossible given the status of the purple medals as revealed later in the series.

Notes

Kamen Rider OOO's Core Medal Collection: 13
- OOO's Core Medal Collection
- It is the only Movie War to feature 3 Rider's names in the title.
- This is the first Movie War film where the Secondary Rider's
"early bird cameo" is not just a brief post-credits scene; with it
appearing twice manipulated by two different users.
- Also, the first actual user of Birth doesn't appear in this movie and Goto would be the second user later in the series.
- The Taja Spinner does not appear when OOO becomes Tajadol Combo for the first time.
- Like all Kamen Rider W titles, the letter in the main title has multiple meanings. In this case, "W" stands for "Double", "Worry", "Wedding" and "Why"
- This is the first Movie War that have secondary Riders from both series fighting together.
- While it was shown that those who used Gaia Memories from Sokichi's time would die if hit by a Maximum Drive, this doesn`t make sense as the Terror Dopant, Beast Dopant and Zone Dopant all survived being hit by Double CycloneJokerXtreme's Maximum Drives (which is stronger than a normal Maximum Drive).
- It is the only film that doesn't feature any monsters in the past that the Riders have fought, despite that the Spider and Bat Dopants were introduced in this film as a flashback.
- Ryu only transforms into Accel in the Movie War portion, due to his equipment being confiscated by Akiko in W's portion.
