* WeakButSkilled: 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 that 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''.

* {{Expy}}: Mitarai could be seen as Kamen Rider's equivalent of [[Anime/MobileSuitGundamSEEDDestiny Yuna Roma Seiran]]. As they are both suitors from a powerful family seeking to marry the daughter of another high-profile family for their own selfish goals.

** Like [[Series/KamenRiderZeroOne Lyon Arkland/Kamen Rider Zaia]], Mamiya gains a special recolored version of his previous users' TransformationTrinkets to become a Kamen Rider, but that's probably the only similarity. Lyon is the [[CorruptCorporateExecutive president of ZAIA Enterprise's American branch]] while Mamiya is a doctor with little publicity. Lyon is a manipulative {{chessmaster}} who plays 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 pay off handsomely in ''Zero-One'''s V-Cinext films even though he dies at [[TheBerserker Kamen Rider]] [[GoneHorriblyRight 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.

Scion of the Sword of Logos-affiliated Mitarai family, and Reika's suitor.

* EvilAllAlong: It was thanks to Ren that Ryoga discovers Mitarai's treachery and was the arranged marriage with Reika turned out to be a ploy to gain control of the Sword of Logos.

!!Tassel Dark/Kamen Rider Tassel

* {{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...

[[caption-width-right:250:The Third Swordsman of Immortality]]

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

* CompleteImmortality: 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 [[SealedEvilInACan sealed away]] again. [[spoiler:Until Chapter 38, that is.]]

* DeathSeeker: His WildCard 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. [[spoiler: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]].

* LastWords: To Touma, [[spoiler:after the latter manages to mortally wound him:]]
-->[[spoiler:"What kind of future you're about to bring... [[VillainRespect That's something I'd like to see.]]"]]

* ResurrectiveImmortality: 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. [[spoiler:Ultimately subverted in Chapter 38.]]

* WhoWantsToLiveForever: Chapter 38 reveals that one of the things that's turned Bahato into such a cynic is his inability to truly die. [[spoiler: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.]]

* GreaterScopeVillain: In [[spoiler:''Film/KamenRiderSaberTrioOfDeepSin'', 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.]]

* DiscardAndDraw: Amazing Siren provides a large number of terrifying powers, such as memory alteration, illusions, and erasure...but it doesn't have Eternal Phoenix's ResurrectiveImmortality.

* UnskilledButStrong: While the powers of ''Amazing Siren'' may be downright terrifying, not to mention that Falchion has stats only surpassed with Blades' Tategami Hyoujuu 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 [[SuperMode much stronger]], while Mamiya struggles against [[StrongAndSkilled Touma]] in his ''base form'' once he's able to get ''Rekka''. Granted, he is still the guardian of Wonder World, but still.

* DiscardAndDraw: Amazing Siren provides a large number of terrifying powers, such as memory alteration, illusions, and erasure...but it doesn't have Eternal Phoenix's ResurrectiveImmortality. As such, Rintaro is able to flat out kill him in battle with a Rider Kick.
