Somewhere in the ice grassland, north of Cyrosland. Yuki was faint and was laying down, then Yuki heard a girl's voice calling his name, because of that voice, he woke up, after he opened his eyes, his first sight was a girl covered by the snow.

"Yuki, Yuki? Are you fine? Yuki?" spoke by the girl, 

"Gladly! You seem not to be dead!". She hugs him and reflects that she seems to be very worried about him, tears can be seen in her eyes, but he doesn't remember most of the things.

"Oww, my head… Um, who are you, who am I, what am I?" Yuki said that and she seemed to be very shocked, 

"A-ree? Are you fine-" she paused for a moment 

"Uhm forget about that… I am Satoshi Suisei, and you are Yuki." 

"What a weird name you gave me, Suisei-chan?" reply by Yuki. 

Suisei was shocked, and then she looked away, she blushed a little, because he didn't really call her by her first name in the past.

"...Yeah, I would be lying if I said that is the name I gave you…-" she said with a panic tone, and was very nervous. Suddenly, they heard a crowd's footsteps, it seemed to be coming in this way., Suisei grabbed his hand and ran.

"Let's go Yuki-kun! The enemies spotted us!", 

"Enemies?!" Yuki was shocked by that action done by Suisei.

 Suisei was running at full speed, because of that, Yuki was really exhausted 

"Wait, wait, I… I am exhausted…", 

Suisei then replies "Then, let me carry you!".

"What, are you seriou- Woah!" Suisei carried Yuki.

When the enemy crowd was in sight with them, the enemy crowd fired bullets, but due to Suisei's ability to run fast, they missed. Some enemies tried to stab them but Suisei was surprisingly good at martial arts.

When they lost their sight, Suisei quickly got into the bush with Yuki. Gladly, the enemy didn't manage to spot them.

"What's going on…" replied Yuki. 

"You seriously lost most of your memory, aren't you? At Least you didn't forget your name teehee" Reply by Suisei with a teasing tone.

 "Long story short, Cyrosland was besieged by Atazuland, with their large army they overthrew our capital city." reply by Suisei. 

"Oh so that's what happens huh?" 

When Yuki said that, Suisei noticed something, "I am surprised you didn't forget about Cyrosland and Atazuland…" feeling desperate because maybe he thinks his own sister is useless and that he forgot about her.

When they were hiding, suddenly, a group of people noticed them, they're one of the Cyrosland elite army, 

"Wait… Suisei, Yuki! I am glad you're still alive, are you all fine?" said the soldier armed with his personal Assault rifle, his name is Mochizuki Isamu. And there is a little girl named Toshinari Kiko, it seems like she was rescued by Isamu. 

Suisei's desperate emotion instantly went and she started to speak "So uh, I may ask, where are most of the Cyroslandia Army now?" Questioned by Suisei. 

"Oh… They haven't report this to you yet? Well, unfortunately, our side surrendered, we had no option but we need to retreat now!" 

Suisei was surprised, "Wh- WHAT?!?" Feeling hopeless, Suisei's desperate feeling came back,

Yuki feels bad hearing that, but he knows there's something he can do. "Suisei, don't let your guard down! I promise that we will revive Cyrosland!", word by Yuki inspired Suisei. Yuki then hugged Suisei.

 "...Tha… Thanks… My younger brother…" Suisei tears no longer dropped. But she accidentally spoiled it.

"Uh, what…" reply by Yuki

"UHM, ops… You… You are indeed my younger brother…"

"What, WHAT?!" Scream by Yuki, 

"Keep your voice down, anyways, I already found the perfect base for us!", spoken by Isamu,

"Huh, a secret base?" said by Suisei with a curious tone, 

"Yeah, just follow me everyone!" They all follow Isamu.

They entered the Rainforest, which is covered by snow biomes. While traveling, they also mind to chat to fill the boring hours.

"Hey little girl, how old are you?" said by Suisei to Kiko. 

"I… I am 15…", 

"Aw cute, that is also Yuki's age". 

Yuki was shocked to know his age "So… I guess I am that young?!?!"

"Hey Suisei, did you actually hide that you're his sister, Suisei?!" Isamu said. 

"No, no, since he was born he knew that I was his older sister, but he just lost most of his memory so he didn't know that." 

With a disbelieving eye, Satoshi Yuki doesn't really believe these words. "I lost my memory?..."

"Well, that is pretty bad… Is this your first time seeing me then?" said by Isamu to Yuki

"Ye- Yeah… I guess my memory loss is very bad…"

Suddenly, they found a dead end, Suisei look at Isamu

"Hm? I thought you know the way, is this it?" said by Suisei with a serious tone

"Well, simple answer is yes, this is the place,, we arrived" Reply by Isamu

"Huh what do you mean…?"

Suisei Looked kinda serious, In order to reveal it, he rubbed the moss and it revealed a hidden platform that will lead them into the Base.

"Huh, this platform is neat… Is this something fantastic story would have..?" Questioned by Suisei

"Yup, it is! Be prepared!" Reply by Isamu 

They stepped into the platform, the platform sent a cool particle, then after a while, it teleported them to an island that they thought was just fiction. The Floating Island.

 "Woah, is this the place? It's very beautiful! "Suisei replied, while Kiko and Yuki were really shocked. 

"Yes, in fact, this island is floating, the rumor about Floating island is actually real, who would know that?" The three were shocked to know that.
