Narrator: After putting down a costly rebellion, the Kamen Riders were met with an even greater danger than before. As the sun grows stronger and the nights grow ever shorter, the Blue Sea Star returns to the sky once more. Believed to be the goddess's home, her followers look to the star and commence celebrations of her rebirth. On the grounds of Garreg Mach Monastery, a grand ceremony is held in honor of this much anticipated event. Every true follower of the Church of Seiros is sure to be in attendance.
Edelgard: Our mission this month is to patrol and set up defenses to stop the assassination plot.
Hubert: I wonder if an assassination attempt is truly the goal of our enemy...
Shotaro: It's a distraction.
Edelgard: Yes, I think so too. A barely concealed secret message, trying to distract us from whatever's really going on. Sloppy, to say the least. And while everyone is out searching for a phantom assassin, they'll be free to accomplish their true goal with ease.
Ferdinand: The monastery houses many valuable weapons. Perhaps that is their aim?
Dorothea: I hear the monastery has a treasure vault too. Seems like the sort of place a foe would like some alone time in.
Linhardt: Garreg Mach is immense, and not just above ground but below as well. Perhaps their aim lies beneath the monastery...
Hubert: It seems to me that we should search the monastery for a clue as to what the enemy might be after. Of course, we must never underestimate the need for preparedness, in case a battle should ensue.
Shamir: A secret meeting, Professor? Oh, we haven't been introduced. I am Shamir.
Edelgard: Shamir is one of the Knights of Seiros. And this young man is-
Cyril: I work for Lady Rhea! And I'm Shamir's apprentice! Oh, the name's Cyril.
Ryutaros: You work for Rhea?
Cyril: Yep. I help Lady Rhea with all kinds of stuff. I've gotta protect Lady Rhea, so that's why I've gotta learn all I can from Shamir.
Shamir: Cyril adores Rhea. That aside, if you need anything, ask.
(Gentaro sneaks behind the other Riders as they discuss their new mission)
Shotaro: A mission befitting my skills, is it? If it's to protect Rhea...I'm with Cyril on this one!
Kazuya: Me too. I won't allow anyone to do harm to her either!
Urataros: Our enemy's true target... What could it be? The monastery has been around for nearly a millennium. It's only logical that there are secrets here. We'd better investigate.
Haruto: Let's go.
Hubert: Can you imagine the archbishop being murdered? I prefer not to consider such a gruesome scenario.
Kintaros: Of course not.
Hubert: Awfully calm, aren't you? I wonder what it takes to rile you up.
Ferdinand: Hmm... Setting fire to the stables to distract everyone, to cause a commotion. It is the oldest trick in the book, but I cannot shake the thought that our enemies may attempt it... I will stand guard and watch over the stable...and the knights' horses. They are truly magnificent.
Linhardt: So sleepy... Too sleepy... I found an interesting book in the library. Got so caught up reading it I forgot to sleep... Interesting discovery though–the coffins of the Four Saints in the sanctum each have their Crests carved into them. I'll need to find a way down there to get a look.
Caspar: Oh. Hey, Professor. I was just reading this letter from my father. Do you know him? He's a pretty big deal in the Empire. He only writes to ask how my training's going, or how many monsters I've killed. Stuff like that.
Bernadetta/Kamikiri Inves: Um... Hi. Right now is, um... Well, right now's OK I guess. If you, um, want to chat...a little.
Ryotaro: Didn't I see you in the dining hall last night?
Bernadetta/Kamikiri Inves: Hey, I get hungry sometimes. Like anyone else! What? Eating at night is bad for you? There's no way that's true. Wait, really?
Dorothea/Siren: People die in every battle. And it can be by sword or spear or magic, but... But depending on who it is that died... Depending on who died, it's different.
Shinji: It's different if it's someone you know who was lost...
Dorothea/Siren: I hope nothing bad happens this month.
Petra/Seamoon Fangire: In Brigid... assassinations are many. I have also been the targeted back in the past.
Sieg: I'm happy you survived.
Petra: The Goddess Tower has an entrance of narrowness. That is most good. The windows are not the most good though. A target of ease for snipers.
Dedue: The monks declined my offer of assistance. They said that no one from Duscur is to be trusted, especially now. Given the circumstances, I cannot fault them.
Felix/Jaguar Undead: Felix: Sending an assassin to the monastery, hm? Hopefully it's someone worth crossing blades with.
Isamu: I hope so too.
Felix/Jaguar Undead: It seems we're cut from the same cloth.
Ashe: I can't stop thinking about Lonato... I'm sorry, Professor. I know this isn't the time, but... I just can't get past it.
Daisuke: Pull yourself together.
Ashe: Thank you. No matter what happens, I promise you I'll do my part. I checked on my brother and sister who were living in Castle Gaspard. Thankfully they're all right. I was worried because they're both so young, but the church in the castle town offered to take them in. That much, at least, is a big relief.
Sylvain: No classes on a festival day! I thought I'd get to spend all day relaxing in the company of some lovely ladies, but now this has happened. Hey, Professor, I know there's talk of an assassination attempt, but do you really think they'll do it on the day of the Rite of Rebirth? I feel like security would be looser some other time. Is there some reason why it has to happen on that day?
Mercedes: The monastery holds many treasures. Maybe the enemy is after one of those? Even so, the idea of stealing from the church is just horrible...
Annette: I bought the ingredients for making some sweet treats I can't wait to eats! Huh? Oh! I know it looks like I'm fooling around, but I'm not. I'm preparing for potential battle during my patrol by making sure I have plenty of food I can eat while walking. Smart, huh?
Takumi: Good thinking.
Annette: I know! Once they're ready, I promise to share some with you.
Ingrid: Professor, while the investigation is important, don't forget to make time for your training. If we have to battle and cannot win, all will be lost. We don't know who our enemy is, so we must be prepared for anything.
Lorenz/Crab Fangire: The Goddess's Rite of Rebirth is the most significant ritual for the Church of Seiros. Could it be that someone has spread these rumors of an assassination plot merely with the intention to hinder the celebration?
Raphael: I bet the enemy's using this assassination nonsense just to sneak in and raid the pantry. What do you think, Professor?
Hitoshi: You may be right.
Raphael: Oh, I'm right all right. My animal instinct is telling me that the enemy is after our best meats.
Ignatz: The monastery's so big. How can we narrow down the list of possible targets? The only places I can think of are the vault and the library, and… I guess that's it.
Lysithea: I don't know who to blame for all this commotion, but it's frankly a huge inconvenience. With everyone stuck on guard duty, our study and training time has been drastically reduced.
Haruto: Some things are more important than that.
Lysithea: Yes, yes, I understand that. But it doesn't change the fact that it's a royal pain.
Marianne: It seems there were forces opposing the church, beyond Lord Lonato... I never thought such forces could exist in this world.
Aruto: We only know a small part of this world.
Marianne: I suppose that may be true...
Hilda: Hello! I'm in charge of managing all records for the Golden Deer House. Oh, but I don't have any information of note right now. Go ahead and continue your investigation. And put a little extra effort into it, please!
Leonie: Seems like donations to the monastery aren't actually kept here. That means the enemy isn't likely to be interested in money. We should turn our attention elsewhere. Then again, I guess some of the plants in the greenhouse could sell for a lot. But that can't really be it, can it?
Hanneman: Unbelievable. What a terrifying story. However, an assassination attempt on Lady Rhea is doomed to fail. Pardon? You think the goal may be different than simple assassination? Intriguing. I suppose the priceless objects in this room could perhaps draw thieves. However, there's no one but me who could make use of them...
Alois: Have you visited the Goddess Tower? It's a sacred place, used for rituals and the like. In general, students aren't allowed entry. But as you'd expect, that rule just excites their curiosity. Some have even tried sneaking in. Well, at least for this month, that kind of behavior is totally unthinkable. We have a lot more security, what with the Goddess's Rite of Rebirth coming up.
Knight of Seiros: On the day of the rite, the monastery will be open to the public, including the Holy Mausoleum. The Holy Mausoleum is where the tomb of the divine Seiros lies. There she slumbers, eternally. That's...pretty much all that in there. Just an ancient coffin. It's sealed with a powerful magic, to protect against would-be grave robbers.
Priest: Do you know what this room is? It is the church's treasure vault. I say treasure, but I do not mean silver and gold and jewels. It mostly contains weapons, artifacts, and the like. Anything that would cause too great a stir should it be stolen? No. The church knows better than to store anything too valuable in such an accessible location.
Monk: There are numerous books in this library that you cannot find anywhere else. But once you are here, you can read them easily enough. I doubt someone would go to the trouble of stealing one. Sometimes Seteth will dispose of books that are deemed inappropriate for the monastery, but that's about it. In a way, I suppose that makes those particular volumes more valuable... Right?
Monk: It would be terrible if the greenhouse was targeted. The plants in here are incredibly valuable. This place contains the heart of Garreg Mach's 995-year history! So many beautiful flowers... Plants that can save or end lives... They are all my precious children.
Shotaro: The Holy Mausoleum? That's it!
(Later that day)
Hubert: The Goddess's Rite of Rebirth is about to begin. Are we going to move forward with our plan?
Edelgard: I believe so. How confident are you in our theory, Professor?
Shotaro: We're not wrong.
Linhardt: No one's intuition is perfect. It's ridiculous not to have doubts.
Claude: Right or wrong, the clock is ticking. All we can do now is stick to the plan.
Seteth: You seem a mite too relaxed for my liking. The Goddess's Rite of Rebirth is about to begin. While we are in the Goddess Tower, we are relying on you to secure the locations that are lacking in defense.
Flayn: May I let you in on something, Professor? My brother can be a bit...callous. He told me that he was concerned about you, and hinted that perhaps you would be better off patrolling a coffin!
Seteth: That was said in jest, Flayn. And in confidence. Please just remain by my side and do not cause any more trouble. As a professor, you would do well to remember that it is your duty to guide your students down the path of righteousness.
Flayn: Please excuse us, everyone. We shall see you again after the ceremony has concluded!
Dedue: It's time.
Dimitri: All right. Let's stick to the plan, and go hide where we can watch over the entrance to the Holy Mausoleum. If anyone suspicious enters, we'll follow them in and take them down. Got it?
(When they get there, they find some uninvited guests)
Edelgard: We were right. Unwanted gusts have come to visit.
Mysterious Mage: Those Central Church dastards have spotted us... Buy me some time while I open the seal on the casket!
Western Church Soldier: I'm on it.
Takumi: Hey, aren't those guys...?
Tsukasa: KickHopper and PunchHopper. I see...(To himself)So, you're working with these invaders, aren't you Daiki?
Claude: Looks like the enemy is going after the casket in the back. Maybe they're going after the saint's bones? Weird. I'd like to defeat them before they can finish the job.
Mysterious Mage: Death Knight! Prove your strength and scatter these fools!
Death Knight: I don't take commands. Or waste my time on weaklings.
Dimitri: That knight looks like he has experience. It would be foolish to challenge him recklessly.
Mysterious Mage: The reinforcements haven't arrived?! If they approach from behind, we can attack them from both sides...
(While Haruto, Gentaro, and Takumi try to stop the Mage, Aruto and Isamu are pitted against the Death Knight)
Death Knight: Like moths to a flame...
Aruto: Yeah, and this flame is burning bright!(He changes into his Flaming Tiger form)There's only one person who can stop you, and that's me!
(Death Knight commands his horse to charge as he and Aruto fight)
Edelgard(thinking): Punching Power: 12.3 t. Kicking Power: 37.3 t. Maximum Jump Height: 22.0 m. Maximum Running Speed: 100 m per 3.6 seconds. Could he actually outwit death?
Gentaro(thinking): Aruto Hiden... Is there any limitations to your incredible potential?
Zero-One Driver: Flaming Impact!(The attack puts major cracks in Death Knight's armor, nearly unmasking him)
Death Knight: I didn't expect to encounter someone like you... How fortunate.
Mysterious Mage: You're too late! The seal will be broken any minute now...
Haruto: Not if we defeat you!
Mysterious Mage: It's no use! The seal is broken. You can't– Huh? A sword?(The mysterious mage pushes back the lid of the tomb. He pulls out a sword. Haruto charges and attacks. The sword is thrown out of the mage's hands. Haruto catches it. The mage prepares a magical attack. Haruto unthinkingly uses the sword to block the attack, and the sword begins to glow with power.)
Mysterious Mage: Huh... What?
Haruto: Interesting.(He uses his magic to make equal versions for Takumi and Gentaro. Cornered, the mage prepares a magical attack. The three Riders overpower and defeat the mage. As they stand by the tomb, they ponder the magical sword. There is an empty space in the pommel where something appears to be missing.)
Catherine/Ladybug Fangire: Is the intruder here?! Oh... Looks like you have this under control. You! Round up any stragglers.
Knight of Seiros: Will do!
(Soon enough, however, there is a commotion on the second floor. Everyone heads up to see Kamen Riders Orga, and Delta, along with Gatack, Garren, Scissors, Gai, TheBee, and Imperer attacking Shamir, Jeralt, Alois, and Gilbert, with even the inexperienced Cyril getting pounded! Fearing the worst, Catherine and the other five transform into their new selves, while Gentaro and Edelgard sneak away, leaving Haruto and Takumi to rush into the Audience Chamber, only to be met by Daiki Kaito/Kamen Rider Diend holding Rhea at gunpoint.)
Kaito: So, I suppose you guys managed to triumph after all, huh? Well, there's going to be a VERY real assassination if I ain't given all of those Crest Stones! Or, do you think this church can handle a hostage crisis? Either way, you'll be owing me those stones!(At those words, Rhea's attitude and voice suddenly changes into a familiar one)
Momotaros(Rhea): Really? Well, you still owe me for that pudding cup you stole!
Kaito: You...?
Momotaros(Rhea): That's right. I... have arrived!
Kaito: Why you...
(Soon enough, the white-clad warrior comes and goes with Diend in tow. With the danger passed, Momotaros exits Rhea's body)
Cathedral-Daytime
Seteth: As all of you have committed a breach of faith, the archbishop will now pass judgement.
Shamir: Inciting a Kingdom noble to rebel. Unlawful entry. The attempted assassination of the archbishop. An attack on the Holy Mausoleum. It is unnecessary to go on, followers of the Western Church.
Priest: What?! We have nothing to do with the Western Church!
Seteth: You have already been identified. Please spare us your second-rate theater.
Rhea: Dishonoring a holy ceremony is worthy of death for a member of the church. You are well past the hope of redemption. If you have any grace remaining, you will willingly offer your life as atonement for this crime.
Priest: No! This isn't what we were told would happen! We've been deceived!
Shamir: It's no use arguing. Whatever your excuse, the punishment stands.
Rhea: May your souls find peace as they return to the goddess...
Priest: Wait! Please! The goddess would never forgive you for our execution!
Priest: Monster! We know you've already slaughtered many of our fellow brethren like this!
Rhea: This concludes the investigation. Please remove these poor, lost souls from my sight.(Camera pans back to reveal either Edelgard, Dimitri or Claude watching. They say nothing, while Gentaro and the other two are also watching)
Tsukasa: Well, that settles it. Still, Kaito...
Isamu: Horobi mentioned that he and Jin were working under the command of someone called Nebula, so it's assumable that Kaito is also a member of his gang.
Edelgard: That's that, I suppose. The assassination attempt, the attack on the Holy Mausoleum... It was all the Western Church's doing. That masked knight who led the attack somehow managed to disappear without a trace.
Hubert: The Church of Seiros clearly isn't as unified as it would hope to appear. It seems the bishop of the Western Church was always opposed to the church being ruled centrally from Garreg Mach. Perhaps they hope to remove the archbishop in order to completely strip the Central Church of its authority.
Shotaro: The Western Church...
Edelgard: Ugh, that's right. Jeralt mentioned that you were raised without any exposure to the church. In order to function more efficiently, the Church of Seiros is split into several smaller entities. The Central Church is the largest and leads the organization from Garreg Mach.
Hubert: The Western Church extends from Castle Gaspard, where Lord Lonato rebelled into the far west. They can be found just beyond the most renowned stronghold of the Kingdom, the Fortress City of Arianrhod.
Edelgard: It seems the knights have been tasked with subduing the leaders of the Western Church. We may be give an opportunity to help them with their mission.
Hubert: To think...our own professor was born in Fódlan and yet knew nothing of the church. I never imagined explaining something so basic to an instructor of mine. You're something of a special case, are you not?
Edelgard: How strange that the archbishop would ask someone like that to lead her students. There's clearly more to that decision than we know.
Caspar: Lady Rhea is pretty scary sometimes...but to execute that whole group just like that? It seems harsh, even for her.
Bernadetta: If one of us does something bad, I wonder what she would do to us!
Dorothea: Professor... Do you agree with the archbishop's actions?
Seteth: There you are, Professor. It seems Lady Rhea would like a word with you. Come with me.
(Outside, it is clear from the broken Progrise Keys and a heavily wounded Kaito that Nebula doesn't tolerate failure)
Apocalypse: So, I take it I'll be up next to deal with those brats?
Nebula: Your opportunity will come, when the time is right. In the meantime, I've collected more power from our partner. And when opportunity knocks, I will unleash it all upon this wretched establishment!
Arundel: The archbishop lives. Not that I had ever placed much faith in those swine from the Western Church.
Flame Emperor: I have news, both good and bad. The remains of Seiros were not in the tomb. However, something else was. The Sword of the Creator.
Arundel: Ah, the weapon wielded by that thief, the King of Liberation.
Flame Emperor: Thief? Hm. At any rate, it is now in the hands of the academy's new professor. I doubt you will be surprised to hear that the Crest Stone had already been removed from the sword when it was found.
Arundel: Hmph. As expected. It would be foolish to keep both in the same location.
Flame Emperor: There's more. The professor was able to awaken the sword's true power. Even without the Crest Stone, the sword glowed red. The professor's Crest is compatible. There is no mistaking it.
Arundel: Absurd. Using a Relic without its Crest Stone should be impossible... The King of Liberation's bloodline should not even... Hmm.
Flame Emperor: They must be allowed to keep it, for now. I do not have enough information about the professor to act. As for your request, I assent. The Death Knight is at your command. Use him well.
Arundel: Good. I believe I will enjoy this a great deal...
Audience Chamber-Daytime
Rhea: I cannot thank you enough for defeating those invaders in the Holy Mausoleum, and especially for protecting the Sword of the Creator. That sword is one of the Heroes' Relics, and the most precious artifact in the church's possession. It is also a weapon of terrifying power. For now...I will entrust the sword to you. Please, use it wisely.
Seteth: Lady Rhea, wait! Do you truly mean to give the Sword of the Creator to this stranger?! Surely it is not the sort of thing that one hands over so readily, even to someone who has the ability to wield it! If someone like Nemesis were to appear again, all of Fódlan would be consumed by war!
Haruto: Nemesis?
Seteth: Nemesis, the King of Liberation. He is an ancient king of mankind who was defeated by Seiros over a thousand years ago. When Fódlan was attacked by wicked gods, it is said that the goddess gifted Nemesis with the Sword of the Creator. Nemesis used that sword to defeat the wicked gods, saving all of Fódlan. Henceforth he was dubbed the King of Liberation. However, his power began to corrupt him until he, himself, turned to the darkness. Saint Seiros was forced to destroy him. Lady Rhea, I beg you to reconsider. Given a little more time, we could more accurately assess this stranger's abilities.
Rhea: No. I have faith, Seteth. Faith that our friend here will not be corrupted by wickedness. Since the death of Nemesis, none have been able to wield the Sword of the Creator. Now, after all those long years of being sealed away, it has returned and found a new master.
Seteth: I...understand. As you wish, Lady Rhea. There you have it, Professor. See that you do not betray the trust the archbishop has seen fit to bestow upon you.
Sothis: The Sword of the Creator. The King of Liberation. Each tale is more confusing than the last! And I really can't read that Rhea at all... That sword is clearly precious... So why is she so keen to gift the thing to you?
Takumi: It certainly is strange.
Sothis: I feel as though we have become entangled in a mystery... And there is one more thing that has been plaguing me. The Sword of the Creator... It somehow feels distinct from other Relics we have seen. Such as the one that... Oh goodness, what was her name? Ca... Cat...
Haruto: Catherine?
Sothis: Yes! Her! The Sword of the Creator differs from her Thunderbrand in one key way. It bears a hole...where something should have been, but is no more. I despise not knowing what is going on! It...it frightens me. And yet... I place my trust in you. I must. Whatever comes to pass...please swear to cut a path that is your own.
Claude: The Sword of the Creator… Pulled right from the legends. I finally found it, and yet it ended up in Teach's hands. Could I even use it anyway? Damn it. There's no telling what's to come…
