It has been exactly two years since Corrin and Kamui were joint King and Queen of Valla; Ryoma as King of Hoshido and Xander as King of Nohr, and so far, everything went smoothly. No war, no battles, absolutely nothing.

"Hey, Brother, is it me or do you think that after two years things became... well... boring?" Kamui asked, clearly she'd missed fighting and sparring against her siblings, whether they are step or adopted ones. "It's not just you, it's been bothering me, too." Corrin sighed.

"I do wonder how Big Brother Xander is doing..." Kamui wondered. "How about we pay a visit to both kingdoms? Like, you go to Nohr to visit Xander, while I go and visit Ryoma in Hoshido. Then, in the next few weeks, we swap." Corrin suggested. "Sure, I really do miss everyone from Nohr." Kamui reminisced. "Same here, but for me, it's Hoshido." Corrin chuckled. "Milord, would you allow Gunter and I to look after Valla?" Flora, the Cold as Ice Maid, volunteered. "If you wouldn't mind, Flora. Thank you." Corrin answered with a nod. "We'll be getting ready to depart in a few days time." Kamui added.

A few days later...

"It's time to go now, Lord Corrin!" Felicia ordered. "Allow me to join you in your visit to Nohr, Lady Kamui." Jakob insisted. "Thank you." Both Corrin and Kamui nodded in agreement. "This is it now, Sister. I shall see you again. Take care of yourself." Corrin smiled. "You too, Brother." Kamui smiled back. The two shook hands and gave each other a brotherly/sisterly hug, and then the two parted ways, with Corrin and Felicia heading towards the Path of Hoshido, and Kamui and Jakob heading towards the Path of Nohr.

In the Kingdom of Hoshido, before Corrin arrives...

"Ryoma, I'll be going out for archery practice." The youngest prince of Hoshido, known as Takumi, reported to his older brother. Ryoma nodded, "Stay safe, brother." And with that, Takumi headed out into the forest.

"Whew, it's been so long since we've been out at war with Nohr and Valla..." Takumi talked to himself as he strolled down to his usual practice area. "And it feels like forever since I have been doing archery practice. But I need to get stronger, way stronger! More than my siblings, anyway..." As soon as he arrived, he got ready with his archery practice. 'I hope that tomato-prince doesn't come out and lash out a fight with me... Yes, we may be friends now, but I do feel a bit uneasy...' he thought as he was about to pull the bowstring. Not long when he released his arrow, a 'whoosh' sound is heard. Takumi turned round, only to see a calming blue portal appearing out of nowhere. Inside that mentioned portal, a girl with dirty-blonde hair appeared. She dons a white sleeveless tank top and navy blue shorts. Her neck is surrounded with a normal blue scarf, all have yellow trimmings. She also wears navy shorts and red fingerless gloves, with her fingertips being covered in metallic bits and has black knee high laced boots. As soon as the mysterious figure got out of her portal, she collapsed.

Witnessing this scene, Takumi had a debate in his mind. 'I want to help her, but I don't exactly know who she is and I'd feared that she is trying to start up a war against our kingdom...' he thought. The wild card knelt down, having decided to aid her and ask what was happening.

"Ugh..." the unknown girl coughed. Takumi rushed to her side. "Hey... are you alright?" he asked. To his surprise, the girl opened her dull grey eyes, then they turned into charcoal black. "What... How... did I get there...?" she questioned the Prince of Hoshido. "Your eyes... They're rainbow, aren't they...?" He whispered. The girl nodded. 'He seems familiar... do I exactly know him?' she thought. "Here, I'll help you get to Castle Shirasagi. You'll get your wounds treated." Takumi offered to help the young girl get up, hanging her right arm around his shoulder and then walk straight to the castle.

"Sakura! We need help here." Takumi called. The pink-haired princess hurried over to her second older brother. "Takumi? W-who's that?" Sakura asked. "I... I don't know but she is wounded very badly. Please, treat her." he insisted. "I'm sorry for all the trouble I caused you... and I didn't mean to interrupt your archery practice." the girl coughed a little, her voice sounded guilty, and her eyes turned from charcoal black to an oceanic blue. "No, it's fine. What's important is for you to get treated." Takumi explained. The blond hair girl nodded and was taken to the treatment room, along with Sakura.

A few hours later, just outside Castle Shirasagi, Corrin arrived at Hoshido, along with Felicia. "Corrin, Felicia, it's good to see you again." Ryoma greeted the two. "Corrin!" Hinoka rushed over and hugged her step brother. "Where's Kamui?" She asked. "Lady Kamui decided to visit her Nohrian siblings, then she will be visiting all of you in a few days time." Felicia explained. "I see. We are all doing very well today. But Takumi has rushed to the treatment room with a young girl we don't even know." Ryoma replied. "Huh? Unless she's some sort of enemy-" Corrin was interrupted. "No, she doesn't appear to be an enemy, Corrin. But I was told to give her some space until she is finished with her treatment." the King of Hoshido explained. "..." Corrin hesitated.

Then, a samurai castle staff rushed to the three and knelt down. "Reporting, milord. A group of unknown monsters is located in the Valley Settlement and are heading towards our kingdom." he explained. "Unbelievable... Our kingdom was in peace for three months and now there's trouble?" Ryoma muttered. "Big Brother, I'd say that we should go to the Valley Settlement and fight those monsters. Felicia, would you come with us?" Corrin turned to Felicia. "O-Of course, milord!" the maid bowed. "C'mon!" Ryoma ordered. The three hurried to the Valley Settlement.

In the treatment room, the wounded girl, who is sitting on a bed, is finished with her treatments. A knock has been heard, and the door revealed to be Takumi. "Hey. I wanted to check on how your condition is." he said. The girl smiled at him, "I am fine now, I haven't thanked you yet for saving me. But, thank you." Her eyes turned from grey to a sunny yellow. "I'm glad that you're okay now." Takumi smiled back. "Oh, I forgot to introduce myself. I am Kagura, princess of Sagaria." the blond girl introduced herself. "And my name is Takumi, and I am a Prince of Hoshido. That's where we are at the moment, Princess Kagura." Takumi explained. Kagura was taken aback (a little bit), but relaxed. "There's no need for formalities, Prince Takumi. I insist that you just call me Kagura." Kagura shook her head. "And there's no need to address me as 'Prince Takumi', Kagura." he chuckled. "May I ask what happened? I did see you coming out of the blue portal, injured." Takumi looked at Kagura, dead straight into her colour-changing eyes.

Kagura's eyes turned to purple, which represents fear. Just as she was about to start... "Kagura, I know that it is a lot to take in, but feel free to take a break when you need to, okay?" Takumi interrupted. "O-Oh... okay. Thank you, Takumi." Kagura stuttered. She inhaled and began explaining, "My kingdom, Sagaria, was invaded, and the invaders are looking for a particular warrior. A warrior that has rainbow eyes..." "It's you, isn't it..." Takumi whispered, and Kagura responded with a sad nod, her eyes turning blue and wanting to let her tears fall down. "They wanted to kill the Rainbow Eyed warriors so that Sagaria would be ruled without those warriors, who can save the world. Anyways, my father had told me to come to this kingdom to see Queen Mikoto again." The Rainbow-Eyed Slayer explained, until Takumi interrupted her. "I... I'm sorry to say, but Queen Mikoto had sadly passed away due to... an attack." He hesitantly replied. "I'm sorry to hear that. But she is a wonderful Queen, she must be a loving mother to you."

Sakura and Hinoka (who heard that a mysterious girl came to Hoshido and wanted to check out who it is) came round to the treatment room to meet Kagura. "I've heard that you came through a portal. Sorry, I didn't mean to eavesdrop or interrupt your story..." the red haired princess apologised. Kagura smiled, her eyes turned yellow, and shook her head. "I accept your apology." the Rainbow Eyed warrior spoke. "I'm Kagura, Princess of Sagaria. It's a pleasure to meet the both of yous. Who might the both of you be?" Hinoka and Sakura smiled. "My name is Hinoka, eldest princess of Hoshido." Hinoka began. "And I'm Sakura. I'm the y-youngest of the seven." the pink haired princess introduced herself. "Wait... There are seven of you? Then who are the other four?" Kagura asked. "We have an older brother named Ryoma, and our step brother is called Corrin. We also have a step sister called Kamui, but she's at Nohr at the moment. And you have Azura, but none of us knows what had happen to her..." Hinoka explained.

Suddenly, one of the castle staff came. "Reporting. We have seen an unknown race, and they are heading to Hoshido." he informed. "What? Already?" Hinoka asked. "I apologise for the suddenness. Both Lord Ryoma and Lord Corrin are already at the  scene." he added. "Ugh, not again..." Takumi muttered. "Big Brother! Big Sister! What should we do?" Sakura panicked. "I'd say that we should help them. Come on, everyone!" Hinoka ordered. "Let's try our hardest, then!" Sakura insisted. "C'mon! We need to hurry to both Ryoma and Corrin!" Takumi ordered. "Please! Let me help." a voice cried. "But, Kagura, y-your wounds..." Sakura stuttered. "It'll be fine. I'll be able to fight alongside you guys." Kagura insisted, her eyes turning orange. "Alright then." Takumi sighed. 'I just hope that they're not after me...' the rainbow-eyed warrior thought. The four headed to the Valley Settlement.

Once the four had arrived, they noticed Ryoma, Corrin and Felicia, who are fighting off against an unknown monster. It had a body of a former human, but the face looks dark and grimm, with white masks, indigo scleraes and red irises. "Ryoma! Corrin! What's going on?" Hinoka hurried to her older brother. "Everyone! We have an unknown monster to face!" Corrin told them. "It sure doesn't look like the Faceless." Felicia stated. "No... It can't be..." Kagura whispered to herself. "Kagura? You k-know these monsters?" Sakura asked. "They're known as the Človeška. Their weak spot is directly at their chest." Kagura informed. "Everyone! Aim for the chest!"

Kagura, wearing gloves that seem to be a weapon, clenched her fists. Using her fingertips, she binds the strings together, that came from the spool, which is located inside a circle container inside her glove, and has created a sword. "That's a cool... uhh..." Takumi pointed out, but couldn't think of what he would call it. "Hm? This? Its name is *Crossclaw. It allows me to create any weapons I want. The thread is made out of... uhh... you know what? How about we get this over with and then I'll explain my weapon to you. Yeah? Yeah, that sounds great." Kagura explained. Hinoka prepared her Steel Naginata, Ryoma with his Raijinto, Corrin and his Blazing Yato and Takumi with his Fujin Yumi. "We need to pin the Človeška down! You two! Please get the arms pinned down! Hinoka, you and I will slice its arms, and Takumi, fire an arrow at its chest!" Kagura ordered. Everyone did as their told. Once Takumi released his arrow, the Človeška screamed out in pain and then dissolving into nothing.

Kagura grew nervous. Corrin walked up to her. "Thank you, stranger. If it weren't for you to be here, we wouldn't know what to do." He smiled. "I-It's fine. But I needed to tell you all the truth..." Kagura lowered her head. "I know those monsters. They came from my kingdom to rid the Rainbow-Eyed warriors so that the whole place would be filled with Človeški. They are after me because..." her eyes turned blue, "I was one of those Rainbow-Eyed Warriors."

"Unbelievable..." Ryoma was surprised.

"What...?" Hinoka was shocked.

"I see... It all makes sense for you..." Corrin replied.

"I'm deeply sorry for all the trouble I have caused everyone..." Kagura bowed.

"Your apology means nothing." A voice that is filled with pure disgust and anger came.

"Hey, Takumi! Knock it off!" Hinoka argued.

"This is all your fault for bringing those monsters in, Kagura! I was a fool in trusting you. We had two years of peace and now you brought those monsters in?!" Takumi raged.

"That's enough, Takumi! Kagura, was it? Don't worry, it wasn't your fault for bringing those monsters in. It's a good thing that you're here to guide us." Ryoma reassured her.

"No, Takumi's right - it is my fault. I think that it's best for me to leave here and never come back..." Kagura shook her head.

"Please, Kagura. I would like it if you stay here for a while. I want to have a conversation with you, just to know why exactly you came here." Corrin insisted.

Kagura looked at Corrin, her blue eyes are no more, switching to grey eyes. She nodded, and everyone went back to Hoshido.

*Try saying Crossclaw 10 times! I dare you! Jk you don't have to ;3
