'This story tells the tale of the Tsurugi Family where they secretly rule; the Land Realm of Japan.'

The planet was shown to look like the Earth.

'A world like the Earth Realm, but has the science of this world studied more, instead of having science and magic being studied equally.'

A young girl was in a dojo training with a kendo sword.

'Kagami Tsurugi loves Japan. She loves the art, the culture, and even her family's tradition.'

The young woman then went against a male kendo fighter and defeated him in 30 seconds.

'Kagami trains only to prove to her mother that she can be better.' 

Every opponent she goes up against, she always wins.

'That she could be more than an assassin like the family women.'

???: Enough!

The kendo fighters get up and Kagami takes off her mask.

'But the only thing that Kagami can't stand more than little freedom is her mother's strictness.'

'Tomoe Tsurugi. Champion swordswoman and head of the Tsurugi Clan. A samurai society that secretly rules Japan.'

(Scene Change)

Kagami was taking a private lesson with her mother outside.

'When Tomoe instructs her everything from swordsmanship to the knowledge of the different realms. She teaches her fencing, kendo, and the use of magic, she even told the stories of King Arthur himself.'

Tomoe: Kagami...

Kagami then stops sparring and faces her mother.

Tomoe: It's time to tell you that we have to leave.

Kagami: What?

Tomoe: Sword of Logos has contacted me and told me that the Four Sages predicted that in 4 years the enemy will attack the Land Realm of Japan.

Kagami: So you're going to give me Noroshi?

She asked with an excited expression.

Tomoe: No! You are not ready. You're barely ready to take over the clan.

Kagami then faded to a sad expression.

Kagami: Then what did you want to say?

Tomoe: I want to tell you that we're moving in a year. To Paris.

Kagami: But... I want to fight the darkness for our clan's honor! I lived for this family and clan!

Tomoe: Yes, you have. You will honor our family someday. But for now, you and I are to leave for Paris so you can adjust there. As the Serizawa family will be there, too.

Kagami: The Serizawa's. Our family's greatest rival. They say we assisted them, but we really saved their skin from Gunmar.

Tomoe: You have studied your history. Impressive.

Kagami: I am to become Kamen Rider Sabela someday. I need to remember our family history entirely if I am to wield Noroshi.

Tomoe: And you will wield it. But for now, you must be ready to meet Suhara's son when we meet them.

Kagami: What's the point of meeting our family's rival if I going to loath him in the future?

Tomoe: It is because Sword of Logos is making the two families try to get along. So when you meet Suhara's son, try your best to get along with him.

Kagami: I will try to, but the Tsurugi and Serizawa families often fight no matter what, even when they first meet each other.

Tomoe: True, I don't get along with Suhara even when I first met him. But... I managed to be able to work with him, even though we don't agree on leadership and swordsmanship.

Kagami tries to see a Serizawa and a Tsurugi as allies.

Tomoe: For now, pack your things, we're leaving tomorrow.

Kagami went to her room.

(Scene Change)

While Kagami packs her stuff, her brother enters the room.

???: Hey, Kagami.

Hiro Tsurugi

She turns around to see her big brother.

Kagami: Oniisan.

Hiro: I hear that you're leaving for Paris with mom.

Kagami continues to pack.

Kagami: Yes.

As she packed up she had a sad expression along the way. Hiro sees his sister sad.

Hiro: Are you okay, baby girl?

Kagami: It's just... I have to leave my friends for the clan.

Hiro: I know... Just be lucky that you're the one who needs protection. Our enemy has no idea of my existence.

Kagami: That's because they don't expect the Tsurugi family ever to have a son for generations.

Hiro: That's right. 

Kagami just continues to pack while having a sad expression on her face. Hiro then decided to help her pack.

Hiro: You know, your lucky that you will become the clan's next leader.

Kagami: But... What if I don't want to become the clan leader. What if I just want to be a teacher of art.

 Hiro: That depends if mom agrees to your dream.

Kagami: You should know mother, she only agrees to anything for the clan. I think you should tell her.

 Hiro: Maybe I should.

Kagami: That was a joke. You know mother doesn't care about what you say. All she does is let you do whatever you want to do. Never what I want.

Hiro: But At least she loves you and gives you attention.

Kagami: That's right. She barely gives you any attention.

Hiro: But she did when dad was still around. 

He then paused.

Hiro: I miss him.

Kagami: I miss him, too. But we can't dwell on it now.

Hiro: Your right. We need to get you to safety.

Hiro then continues to help Kagami pack her things.

Kagami: By the way...

Hiro stops and faces his little sister.

Kagami: Aren't you coming with us?

Hiro: Nah. I'm leaving for the Techno Realm.

Kagami: Why?

Hiro: Because I thought I should leave to a world where I can help others... Even if I'm not a Swordsman. But as a doctor.

Kagami: I see.

Hiro: Anyway, you better get going. Your flight is in five hours.

Kagami: Your right. Mother will yell at me if we're late for our flight.

Timeskip

Tomoe and Kagami made it to Paris. Kagami tried to sign up for a fencing class but she lost to Adrian and got akumatized. Luckily she was saved by Ladybug and Cat Noir. As she made it home she made sure to not tell her mother about it.

(A/N: She still acts her way in Frozer, Catalst, and Mayura. I just don't have time to write them.)
