Characters from Kamen Rider Saber: The Phoenix Swordsman and the Book of Ruin

Bahato/Kamen Rider Falchion (Unmarked Spoilers)

Bahato/Kamen Rider Falchion (I)

Portrayed by: Masashi Taniguchi (live), Eitoku (suit, movie), Takuma Komori (suit, main series)

"All shall return to the void."

A swordsman that is said to be immortal, and wielder of the Sword of the Void Mumeiken Kyomu and its token Wonder Ride Book Eternal Phoenix. Once a close friend and companion to Yuri and another swordsman, Bahato descended into madness after he killed that swordsman in revenge for the latter murdering his family, leading Yuri to seal him within the Book of Ruin. He once escaped his prison and attempted to use the Book of Ruin to erase Wonder World and Earth from existence, but his plan was stopped by Touma and was once again sealed away within the Book of Ruin.

In Chapter 34, Master Logos releases Bahato from the Book of Ruin, ushering him into the world once more to help the former's plan of recreating the Book of All and remaking the world in his image.

Tropes that apply to him in general

The Immortal Swordsman of the Void

• The Ageless: He became a Swordsman thousands of years ago. When the Sword of Logos encounter him after he escapes from the Book of Ruin, he barely looks as if he's aged at all nor does he show any signs of decomposition, save for the bit of bone sticking out of the left side of his face. That bit of bone is strangely missing when he appears in the show proper.
• Antagonist Title: He's the titular Phoenix Swordsman, though his proper title is the Immortal Swordsman.
• Axe-Crazy: He's an Omnicidal Maniac who wants to erase Wonder World and Earth from existence, and he's more than happy to kill any Swordsman who crosses his path. As stated by Yuri, he was not always this way.
• Big Bad: Of the Kamen Rider Saber: The Phoenix Swordsman and the Book Of Ruin movie.
  • Big Bad Ensemble: He forms one with Master Logos, who released him from the Book of Ruin as the Mumeiken Kyomu is required for the former's plans to recreate the Book of All.
• Breaking Old Trends: While Bahato is not the first Kamen Rider who debuted in a film to appear in the show he's tied to, he is the first Movie Rider to play a role in the main story. Since Bahat can simply revive himself, he is instead sealed within the Book of Ruin once more and placed in the Southern Base's forbidden library by Master Logos. He makes his official appearance in the show in Chapter 34, released once again from the Book of Ruin by Master Logos.
• Cessation of Existence: He intends to make both reality and Wonder World disappear by using the Book of Ruin that he was previously sealed inside of. This is also the main reason why he continues to work with Master Logos.
• The Comically Serious: Throughout the entirety of Mei and Yuri's efforts to persuade him in Chapter 37.
• Complete Immortality: He literally cannot die. Nothing in the series thus far has proven capable of putting him down for good, and thus every time he's had to be sealed away again. Until Chapter 38, that is.
• Contrasting Sequel Antagonist: To Kohgane, a fellow Movie-exclusive Kamen Rider. Kohgane is the manifestation of an artificial Golden Fruit, while Bahato was an ordinary human who came to possess the Mumeiken Kyomu and its token Wonder Ride Book, which grants him the ability to resurrect if he's ever killed. In regards to their roles, Kohgane appeared near the end of Gaim well after the events surrounding the Golden Fruit and Helheim were resolved and the events of the film he's tied to were made to seem as if it were a dream by Lapis. Bahato, thanks to his immortality, had to be sealed away, both prior to the series' beginning and at the end of his own film. Unlike Kohgane, who's described as being a loose end, Bahato's possession of Kyomu makes him one of Kento's targets, since his sword, along with the other Seiken, play a part in Master Logos' plans to recreate the Book of All.
• Death Seeker: His Wild Card style is obviously motivated by his hatred against all humans, but as it turns out, also by a desire to end his immortal life. If he keeps on attacking everyone in sight, maybe someone will eventually find a way to put him out his misery. He finally gets his wish in Chapter 38, dying by Touma's blade, and when his spirit appears in the Final Chapter he's shown to be way calmer.
  Bahato: A deathless body... endless rebirth! You humans cannot possibly comprehend such despair.
• Dem Bones: A portion of his skull sticks out on the left side of his face when he appears in Phoenix Swordsman and the Book of Ruin. This trope no longer applies once he appears in the main show.
• Even Evil Has Standards: Downplayed. Bahato's reaction to Issac's decree in Chapter 36 that the world fight for its survival is a rather bemused grimace. He asks Isaac in the following Chapter why he doesn't just end the world immediately, and only has this to say when Isaac reveals he's drawing out the conflict For the Evulz.
  Bahato: (resigned, yet annoyed) Humanity's nature hasn't changed one bit.
• Evil Counterpart: He's this to Kento, who (like Bahato) is also a wild card in the grand scheme of things. Kento is only an enemy to his fellow swordsman because he believes that sealing away their Seiken will prevent the Bad Future Kurayami showed him from happening. Bahato considers every Swordsman to be his enemy and will not stop until he's killed every last one.
• Evil Laugh/Mad Laugh: As an Omnicidal Maniac, who is definitely enjoying himself for a good part of the time, these two types of laugh are naturally his bread and butter.
• Fallen Hero: In Chapter 34, Yuri reveals that Bahato was once a genuinely heroic swordsman up until his family was murdered by their unnamed companion, who Bahato killed in retaliation.
• Humans Are the Real Monsters: Firmly believes in this. His intentions in erasing the real world and the Wonder World are to actually restart both, believing that humans, their endless conflicts, and overly repeated mistakes in their unending quest for power had permanently tainted history.
• Maddened Into Misanthropy: Bahato's family was murdered by his and Yuri's friend, having become obsessed with power. Suffice to say, he did not take their deaths well at all, considering every Swordsman who crossed his path his enemy and wanting to erase both Earth and Wonder World.
• No Shirt, Long Jacket: The coat may obscure it somewhat, but it's obvious that he is not wearing a shirt as far as we can tell.
• Not in This for Your Revolution: When Master Logos undoes the seal on the Book of Ruin, Bahato wastes no time in making it clear that, despite whatever reasons Master Logos has for releasing him, he will not help him recreate the Book of All. The only reason Master Logos lets him do as he pleases is because Bahato's current goal is to kill every last Swordsman who crosses his path, which makes it easier for him to collect their Seiken and Wonder Ride Books afterwards.
• Last Words: To Touma, after the latter manages to mortally wound him:
  "What kind of future you're about to bring... That's something I'd like to see."
• Painful Transformation: Downplayed. During his transformation sequence, he grabs Kyomu by the blade (which is set ablaze no less!) with nothing but his bare hand. Despite this, he shows zero discomfort.
• Red Baron: He's known by the Sword of Logos by as the Immortal Swordsman. A fitting title, given his possession of a Wonder Ride Book housing the power of the mythological phoenix. He did not earn that name without reason, since he can revive himself should he die.
• Redemption Rejection: After learning about his past, Touma tries to appeal to him. Bahato can only laugh at Touma's attempts and states that anyone with a Seiken is his enemy, making it clear that he will not listen to reason.
  • Yuri and Mei try once more to reason with him in Chapter 37. Despite the attempt being much more comedic, it works just as well as Touma's attempt did.
• Restart the World: This is his ultimate goal. Believing that humanity's tendency to repeat their mistakes and inclination towards war has tainted history, he intends to wipe the slate clean by erasing both the Wonder World and Earth.
• Resurrective Immortality: As his Wonder Ride Book might suggest, thanks to Eternal Phoenix and the Mumeiken Kyomu, Bahato can revive himself in the event of his death. This is also why he had to be sealed in the first place, since no one has the ability to kill him permanently. Saber is ultimately unable to do so either and thus has no choice but to seal him away again. Ultimately subverted in Chapter 38.
• Sealed Evil in a Can: He was previously sealed within the Book of Ruin. He's eventually released from his prison, and the moment he's out, he wants to destroy the real world and Wonder World. Saber manages to reseal him within the Book of Ruin at the end of the film, since Bahato can simply revive himself through Kyomu and his Wonder Ride Book, all while continuing to cause destruction. In Chapter 34, Master Logos releases him from his prison to help aid him in his plans.
• Spell My Name With An S: His name has been widely debated between either "Bacht" and "Bahat/Bahato".
• Start of Darkness: Bahato's family was murdered by his and Yuri's third friend for reasons unknown. This shattered Bahato's psyche and convinced him that Humans Are the Real Monsters. He attempts to Restart the World with the Book of Ruin, but is sealed away by Yuri before he can.
• Took a Level in Badass: Bahato was plenty strong already thanks to his Resurrective Immortality and overwhelming strength, and the main reason why he lost to Touma was because the latter used the power of Emotional Dragon to seal him back inside the Book of Ruin. When he makes his return in Chapter 34, he's just as dangerous as the last time they fought, if not more so.
• Walking Wasteland: How he makes his grand debut in The Phoenix Swordsman and the Book of Ruin: every step that he takes in the Wonder World causes the area's nature around him to slowly disintegrate.
• We Used to Be Friends: He, Yuri, and an unknown swordsman were all close friends up until the latter third murdered Bahato's family due to his sudden lust for power. Whatever friendship Bahato and Yuri had was gone in that moment, and Bahato himself felt betrayed by Yuri sealing him within the Book of Ruin.
• Wild Card: As he hates all Swordsmen, he is liable to attack both the heroes and villains alike.
• Who Wants to Live Forever?: Chapter 38 reveals that one of the things that's turned Bahato into such a cynic is his inability to truly die. Luckily for him, Touma fixes that not long after, and his spirit's appearance in the Final Chapter suggests he's finally found peace in death.
• You Have Outlived Your Usefulness: Master Logos has no more use for Bahato after Chapter 35 and is perfectly content with letting Touma seal him away again. His only response is a deranged laugh as he fades away.
  Isaac (to Bahato): This is where your role ends.

Tropes exclusive to him as Kamen Rider Falchion

Battō! Eternal Phoenix! Kyomu! Shikkoku no Tsurugi ga, Mu ni Kisu.^note Unsheathe! Eternal Phoenix! Void! The jet-black sword shall turn all into nothingness.

• Cool Sword: Given the series he's tied to, of course. However, his blade, the Mumeiken Kyomu, is unique in that it's Elemental Power is... nothing. As in Emptiness, and the absence of life. This is notoriously both a powerful element, and an unpredictable one.
  • This also extends to his blade's designation. Kyomu is classified as a Haken or Supreme Sword. What makes it so much stronger is revealed in Chapter 34, the episode that Bahato returns in; it can nullify the powers of another Seiken or stop finishers entirely.
• Feather Motif: Tying with his Mythical Motif, Falchion has a feathered wing spreading out from his left shoulder and down his left leg. Even his belt has feathers attached to it.
• Finishing Move:
  • Mumeiken Kyomu:
    • Musou Giri: has four variations.
    • Falchion performs a downwards orange energy slash. As he does so, an orange energy phoenix spawns, and thrusts the slash in the enemy's direction, sending them flying.
    • Falchion creates an orange and black aura around himself before sprouting a pair of phoenix wings to take to the air. He then performs a horizontal orange energy slash.
    • Falchion delivers a slash of orange flames at close range before launching a larger, horizontal slash projectile after a short charging period. Both attacks produce waves of heat upon impact.
    • Falchion covers the Mumeiken Kyomu with flames and swings it, creating a phoenix made of fire that flies into the enemy.
    • Mugen Ittotsu: Falchion scans a Wonder Ride Book against the base of the blade and performs an attack based off of it.
    • Eternal Phoenix: Has two variations.
    • Falchion delivers a double orange energy slash. As he does so, an orange energy phoenix spawns, and thrusts the slash in the enemy's direction, sending them flying.
    • Falchion covers the Mumeiken Kyomu with flames and swings it, delivers a orange energy horizontal slash, the slash creating a phoenix made of fire that flies into the enemy.
• Greater-Scope Villain: In Kamen Rider Saber: Trio of Deep Sin, the Mumeiken Kyomu is heavily implied to be sentient and serves as the source of power for all three of the film's main antagonists.
• Meaningful Name: "Falchion" refers to a European sword that eventually came to be used by the nobility—a gold-plated and engraved Falchion can even be found in Cosimo I de' Medici's personal Coat of Arms.
• Mythical Motifs: Fitting for someone who is said to be an immortal swordsman, Falchion's motif is based around the mythical phoenix; a bird that is reborn shortly after it dies.
• No-Sell: Kyomu allows Falchion to either bypass his opponent's Finishing Move or cause it to end prematurely.
• Playing with Fire: Zig-zagged. Although his Wonder Ride Book is associated with fire, on account of it being based on the phoenix, Falchion's power isn't really over fire, but instead The Power of the Void.
• The Power of the Void: The element that Falchion's Mumeiken Kyomu resides over, which makes him a difficult opponent for Touma and the Sword of Logos, given the unpredictable nature of his weapon.
• Red Eyes, Take Warning: Falchion has orange-tinted red eyes, and he's every bit as powerful as you'd expect from a villainous Kamen Rider.
• Sudden Soundtrack Stop: Reflecting his Power of the Void, in The Phoenix Swordsman and the Book of Ruin, when Falchion draws his sword for the first time, all the music and sound effects stop even as the Eternal Phoenix itself is summoned from the book. It goes on long enough to seem like it might be an error... and then Bahato's maniacal laughter cuts through the silence.
• Weak, but Skilled: Averted. In terms of ability, Falchion only falls short behind Blades in Tategami Hyoujuu Senki form. Even then, he can easily outlast his opponent via his Resurrective Immortality.

Tropes that apply to him in general

---

• Disappeared Dad/Missing Mom: Both his parents died during the events of the main series. Coincidentally, Mamiya also said that he also lost his father during the events of the main series...
• Elective Mute: Due to the trauma from the incident eight years ago, only blurting out his Trauma Buttons when triggered. He overcomes it by the V-Cinema's end.
• Literal Split Personality: When Riku Mamiya took ahold of Mumeiken Kyomu, it split him into two selves, the child as Riku, who represents his innocence, and Mamiya, who desires revenge against the swordsmen.
• No Full Name Given: He's only known by his given name until the second half of the V-Cinema, where his original surname is revealed to be Mamiya.
• Perpetual Frowner: Hasn't smiled since the death of his parents, only doing so around Lucky.
• Trauma Button: Fire and swords are these to him, since his parents died in a house fire with Saber at the scene. This foreshadows his true identity as Mamiya, as Mamiya wanted to avenge his parents' death at the supposed hands of Touma.

Mamiya (Unmarked Spoilers)

Mamiya/Riku Mamiya/Kamen Rider Falchion (III)

Portrayed by: Ryo Kimura (live), Yuji Nakata (suit)
Young Mamiya Portrayed by: Touma Matsuhara

A doctor and childhood friend of Touma.

He is later revealed to be the true third wielder of the Mumeiken Kyomu and the primary user of the Amazing Siren Wonder Ride Book.

Tropes that apply to him in general

The true Third Swordsman of the Void

• Backstory Invader: Used Amazing Siren's power to write himself into Touma's life as his other childhood friend besides Kento. A more benign version of this is implied to happen in the epilogue, as the adult Mamiya ends up alive in the new world, while it's implied he became an actual part of Touma and Kento's childhood as he'd initially posed himself as.
• Big Bad Friend: Is the mastermind of the plot to eliminate Touma and the other swordsmen, all while posing as Touma's friend.
• Casting Gag: This is not the first time Ryo Kimura portrayed a black-white colored Dark Rider penned by Takuro Fukuda.
• Contrasting Sequel Antagonist:
  • Both Bahato and Mamiya are the wielders of a Wonder Ride Book, the Haken Bladriver and the Mumeiken Kyomu, allowing them to transform into Kamen Rider Falchion. They also have encountered a traumatic incident where their loved ones are slaughtered (Bahato losing his family thanks to a former friend turned evil and Mamiya losing his family to a house fire). However, while Bahato was an Ax-Crazy, nihilistic swordsman seeking to destroy the world with no concern for any casualties, Mamiya is more sane and calculative and targets the swordsmen specifically. In terms of goals, Bahato intended to destroy Earth and Wonder World immediately to Restart the World, believing Humans Are the Real Monsters, while Mamiya is driven solely by revenge against the Sword of Logos' swordsmen and spread out his plans over eight years before striking. Finally, while Bahato is slain by Touma, all the while never seeing the positive side of mankind or joining Touma while still admitting he'd like to see whatever future he creates, Mamiya is peacefully convinced to abandon his plans by Touma who reconciles with him and Riku; as such, Mamiya prevents his younger self from ever touching the Kyomu, undoing and preventing all the tragedies in the film.
  • Like Lyon Arkland/Kamen Rider Zaia, Mamiya gains a special recolored version of his previous users' Transformation Trinkets to become a Kamen Rider, but that's probably the only similarity. Lyon was the president of ZAIA Enterprise's American branch, while Mamiya is a doctor with little publicity. Lyon was a manipulative chessmaster who played every single situation to put the odds in his favour to bring down Aruto and his friends and damage relations between humans and Humagears, while Mamiya's plot is simple revenge against the swordsmen, getting some folks involved with a deal. Finally, Lyon's efforts paid off handsomely in Zero-One's V-Cinext films even though he would die at Kamen Rider MetsubouJinrai's hands, while Mamiya is peacefully talked out of his plans, prevents his younger self from touching Kyomu and survives the events in his film.
• The Faceless: His child self has the upper half of his face obscured during flashbacks for most of the V-cinema, hiding the fact that he and Younger Riku are the same person.
• False Friend: Acted as this to Touma, as well as the other swordsmen so he could secretly erase their memories.
• Foreshadowing:
  • When coming to play with Riku alongside Touma, he suddenly develops a leg cramp. Coincidentally, Kamen Rider Falchion suddenly appears to attack Riku when he is nowhere to be found...
  • Also, one close look at the opening of Trio of Deep Sin has a man with a white sleeve grabbing Kyomu. Mamiya also wears the same white clothes throughout the movie, hinting at him being one of the users of Mumeiken Kyomu.
• Irony: The details are a bit scrambled, but if the events of the movie are interpreted as breaking a Stable Time Loop, it means that while he'd been convinced Touma had killed his father and given him Trauma-Induced Amnesia, he'd actually been the one to kill Touma and erase his own younger self's memories of the event.
• Literal Split Personality: When Riku Mamiya took ahold of Mumeiken Kyomu, it split him into two selves, the child as Riku, who represents his innocence, and Mamiya, who desires revenge against the swordsmen.
• Long Game: To achieve his vengeance against the swordsmen, he would build up trust with them for eight years, before literally going behind their backs to rob them of their memories, resulting in them disappearing.
• The Man Behind the Man: He is the true wielder of the Amazing Siren Wonder Ride Book and the one who gave its power to Shinozaki and Yuina.
• My Future Self and Me: An unusual version; while he was split off from the younger Riku using Kyomu and technically counts as a distinct entity, he seems to be the future version of Riku brought back into the past, since his scrambled memories of his "father" (actually Touma) end up happening late in the film, and getting his memories back as Riku allows him to remember his childhood growing up under Touma.
• No Full Name Given: He's only known by his surname until the second half of the V-Cinema, where his name is revealed to be Riku.
• Rewriting Reality: As the true holder of the Amazing Siren Wonder Ride Book, he has the ability to rewrite memories of each person behind their backs.
• Spectral Weapon Copy: Judging with his interaction with Shinjiro, he can duplicate copies of Amazing Siren.
• Trauma-Induced Amnesia: After he touched Kyomu and split apart from Riku, he virtually lost every memory he had except for his father dying in the events of the main series. He only remembers when Riku clashes with Rekka against him.
• Walking Spoiler: As this entry indicates, it's impossible to talk about him without revealing a major twist in the V-Cinext movie; the whole folder would have been white from putting spoiler indicators as well.
• Why Did It Have to Be Snakes?: He's not too fond of dogs.

Tropes exclusive to him as Kamen Rider Falchion

Battō! Eternal Wonder! Kyomu! Shinjuu no honō de subete ga mu ni kisu!^note Unsheathe! Eternal Wonder! Void! The flames of the Divine Beast return all into nothingness!

• Discard and Draw: Amazing Siren provides a large number of terrifying powers, such as memory alteration, illusions, and erasure...but it doesn't have Eternal Phoenix's Resurrective Immortality.
• Dynamic Entry: For the final battle, Falchion dives straight near Touma and Riku while Wreathed in Flames, creating an explosion around him.
• Good Wings, Evil Wings: Sprouts a pair of wings behind him during his transformation.
• Power Echoes: His voice is distorted and echoed while transformed to keep his identity a secret.
• Technicolor Fire: His flames are colored blue.
• Unskilled, but Strong: While the powers of Amazing Siren may be downright terrifying, not to mention that Falchion has stats only surpassed with Blades' Tategami Hyōjū Senki form, Mamiya is notably less skilled compared to the other users of Falchion, who at least were able to fight on par with their respective riders until they became much stronger, while Mamiya struggles against Touma in his base form once he's able to get Rekka. Granted, he is still the guardian of Wonder World, but still.

Yuina Tachibana (Unmarked Spoilers)

Yuina Tachibana/Kamen Rider Falchion (V)

Portrayed by: Rin Asuka (live), Danki Sakae (suit)

Kento's fiancée, who lost her previous one eight years ago.

---

The Fifth Swordswoman of the Void

• Becoming the Mask: In spite of her protestations to the contrary, it's apparent that she developed genuine feelings for Kento during their time together.
• Big Bad Duumvirate: Well, Triumvirate, but she acts as one with Shinjiro Shinozaki and Mamiya as the wielders of Amazing Siren in Trio of Deep Sin.
• Birds of a Feather: She meets Kento after she drops her copy of Aladdin and the Magic Lamp, upon which the swordsman revealed his own copy. They meet again in a similar manner in the film's denouement.
• Bitch in Sheep's Clothing: She's introduced as Kento's sweet fiancée, yet is revealed to have pursued the relationship in order to get close to him to kill him.
• Crusading Widower: Is motivated by revenge against Kento due to blaming him for the death of her previous fiancé.
• Dark Action Girl: She is the sole female wielder of Mumeiken Kyomu, and puts up a great fight against Kento, only being defeated when Kento resonates with Ikazuchi and obtains the Arabiana Night Wonder Ride Book.
• Impaled with Extreme Prejudice: Is mortally wounded when Kyomu floats up and runs her through for failing to uphold her end of her bargain.
• The Lost Lenore: Her first fiancée was one of the major casualties of the main events of the series, and because of this, she made a contract with Amazing Siren to assassinate Kento.
• Red Eyes, Take Warning: Her eyes glow red when she calls upon Amazing Siren's power.
• Why Can't I Hate You?: Her time with Kento led her to actually come to love him in the end, even if she still wants revenge for her late fiancé.
  Yuina: Even now I still hate you... But you're just too kind...
• You Have Failed Me: On the receiving end of this, when the Mumeiken Kyomu impales her for failing to complete her contract.

Shinjiro Shinozaki

Shinjiro Shinozaki/Kamen Rider Falchion (IV)

Portrayed by: Satoshi Hashimoto (live), Yuji Nakata (suit)

"For the lives of all you've sacrificed in your battles... I will rid the world of each and every swordsman!"

The third/actually fourth wielder of the Mumeiken Kyomu, who claims to be Rintaro's long-lost father. Using the Amazing Siren Wonder Ride Book, he transforms into Kamen Rider Falchion Amazing Siren.

Tropes that apply to him in general

The Third/Fourth Swordsman of the Void

• Affably Evil: He's cordial when speaking to Rintaro and clearly isn't thrilled about having to fight his son, though he sees it as his duty.
• Alliterative Name: Shinjiro Shinozaki.
• Anti-Villain: In contrast to the other two Falchions, Shinjiro employs little in terms of manipulation or trickery; approaching Rintaro directly and outright telling him what he's doing and why. This is because he's fighting exclusively to protect the world from what he sees as Destructive Saviors rather than a personal grudge, taking no pleasure in what he's doing.
• A Million Is a Statistic: Defied. The brand of revenge Shinjiro seeks is for the nameless dead who ended up as the collateral damage of a battle between the swordsmen and the Megid.
  Rintaro: But we only fight to save this world.
  Shinjiro: And thanks to that, countless people have died!
• Big Bad Duumvirate: While initially presented as the main villain of Trio of Deep Sin, it turns out he is part of a Triumvirate with Yuina Tachibana and Mamiya.
• Blood from the Mouth: After being mortally wounded by Rintaro, he spits out blood from his mouth.
• Contrasting Sequel Antagonist: Both Kamen Rider MetsubouJinrai and Shinjiro are movie-exclusive Riders with special Transformation Trinkets and drivers to transform into special Riders with special suits... except that's the only similarity. MetsubouJinrai is the painful union between Horobi, Jin, Ikazuchi and Naki, all of whom are robots (until it comes to Jin), while Falchion needs only Shinjiro, a human, for a much simpler transformation and the same goes for Yuina and Mamiya. MetsubouJinrai is a Destructive Savior, rampager, Knight Templar and an ignorant, single-minded loon intent on destroying both humans and Humagears while Shinjiro only wants to erase the swordsmen from history to avenge the deaths of the deceased victims caught in the swordsmen's war, genuinely believing his actions would actually save more lives. Finally, MetsubouJinrai succeeds in destroying majority of their opponents, while Shinjiro is offed by Rintaro and fails to accomplish his goals, especially when Mamiya is peacefully talked out of his plans.
• Daddy Had a Good Reason for Abandoning You: Claims that he abandoned his wife and son in order to protect them.
• Evil Old Folks: Looks to be in his sixties, and seeks the death of every swordsman. Though the "evil" part is subverted as there was genuinely no malice behind his actions.
• Fallen Hero: Much like Rintaro, he used to defend the same people he did when the Megid began warring against the Sword of Logos. However, the amount of casualties involved ultimately ended up breaking him, resulting in him taking the Mumeiken Kyomu to prevent the tragedies from ever happening by erasing the Swordsmen from history.
• Four Is Death: He's actually the fourth person to take up Mumeiken Kyomu — and, coincidentally, dies after Rintaro inflicts a fatal blow on him.
• Freudian Excuse: His town where he resided in was razed during the events of the main series. Because of this, he took up Mumeiken Kyomu and sought to erase the swordsmen from history.
• Hero Killer: Not quite "kill", but he along with his associates is responsible for erasing most of the swordsmen by wiping everyone's memories of them.
• Luke, I Am Your Father: Declares this near-verbatim to Rintaro upon their first meeting.
• Mysterious Past: Claims to have been Rintaro's father and to have at one point been a "hero", but very little is known about him.
• Revenge: Downplayed. While all three Falchions seek vengeance of some sort against the swordsmen, Shinjiro's crusade is more about giving Due to the Dead (and protecting others) rather than anyone specific.
  Shinjiro: The grudge of the dead lives on forever! ...And it will continue to shackle you until the end of times.
• So Proud of You: Just before being defeated by Rintaro, he acknowledges that he has grown up.
• Well-Intentioned Extremist: For all his rewriting of others' memories and his attempting to wipe the Swordsmen from history, he genuinely believed he would save more lives by doing so.

Tropes exclusive to him as Kamen Rider Falchion

Battō! Eternal Wonder! Kyomu! Shinjuu no honō de subete ga mu ni kisu!^note Unsheathe! Eternal Wonder! Void! The flames of the Divine Beast return all into nothingness!

• Dark Is Evil: He is clad in black, just like the original Falchion's users, with the main difference with thanks to the Amazing Siren Wonder Ride Book (and also replacing the orange colours with white). This is ultimately subverted, as his actions, while reprehensible, were borne out of genuinely good intentions.
• Discard and Draw: Amazing Siren provides a large number of terrifying powers, such as memory alteration, illusions, and erasure...but it doesn't have Eternal Phoenix's Resurrective Immortality. As such, Rintaro is able to flat out kill him in battle with a Rider Kick.
• Feathered Fiend: Still has the bird motif on his shoulder, a reference on how sirens were sometimes depicted as birdlike rather than mermaid-like.
• Mind Rape: Unique to Amazing Siren, it has the ability to induce fear-induced hallucinations to their enemies, as Rintaro found out the hard way.
• Our Sirens Are Different: His motif is based on the mythological siren, whose singing lured unwitting sailors to their deaths.
• Rewriting Reality: By taking a page off someone's back, he can remove their memories of others, causing members of the Sword of Logos to disappear.
• Shock and Awe: Appears to use lightning, in contrast to Mamiya using fire.
• Sirens Are Mermaids: The cover of the Amazing Siren Wonder Ride Book features a siren with a mermaid's tail.
• Weak, but Skilled: The statistics of Falchion while using the Amazing Siren Wonder Ride Book show it to be actually lower compared to Eternal Phoenix, and it doesn't have the immortality-inducing powers the latter has, but still more powerful than that of Saber, Blades and Espada's base forms. However, Shinjiro is one of the most skilled users of Amazing Siren, and he comes nearly close to defeating Rintaro had it not been for him getting access to Tategami Hyōjū Senki.

Lucky

Portrayed by: Festa

A Golden Retriever adopted by Touma and Riku.

---

• Life Will Kill You: Ultimately passes away due to old age at the end of Trio of Deep Sin.
• Nerves of Steel: Any other dog would have gone berserk at a stranger threatening its owner, yet Lucky is oddly unperturbed, even going so far as to lick Falchion. This is actually a hint that Riku and Mamiya are one and the same.

Characters from Kamen Rider Saber Spin-off: Kamen Rider Sabela & Kamen Rider Durendal

Rui Mitarai

Rui Mitarai/Amanojaku Megid

Portrayed by: Hiroshi Yazaki (live), Hirotsugu Mori (suit)

---

• Ambition Is Evil: His motivation is to take over the Sword of Logos for his own ends, by marrying Reika and using the leverage of two prominent SoL families as his assets.
• Bitch in Sheep's Clothing: He presents himself as an affable young man who pursues Reika's hand with genuine concern for her... then it turns out it's all part of his evil plan.
• Evil All Along: It was thanks to Ren that Ryoga discovers Mitarai's treachery, as well as the arranged marriage with Reika turning out to be a ploy to gain control of the Sword of Logos.
• Light Is Not Good: He's shown wearing a white suit when Ryoga uncovers his treachery.
