A boy woke up from unconsciousness, when he woke up, he was truly dumbfounded, there's no memory to explain who he is and it seems like his location is a grassland covered by snow biomes. When he looked around, he then realized there was a girl hugging him this whole time.

"Eeeek! The boy spoke with a surprised and embarrassed tone then he pushed her preventing her from hugging him any longer

"Ouch, that's rude! Yuki-kun!" the girl spoke after he pushed her, she pouted a little

"...Yuki?" The boy said with a puzzled tone

"Nnn? What's wrong?" The girl spoke with a curious tone, "Isn't that your last name?"

"Oh Really? Uh… Sorry but, I don't remember anything…" The boy said that with a surprised tone, now that he knows his name now.

"...Huhh?!" The girl spoke in shock, "You lost your memory? Entirely?"

"Not entirely… I still do remember this language…" he stopped looking at her for a while before proceeding with his question. It was silent for a moment, Yuki spoke "So uh… Who are you-?!". When he looks at her, she was crying,

"I… I am… am…" the girl's sentence keep got cut off because of her emotion

"Yo- You are?" Yuki was curious

She jumped into him to hug him, "I am Suisei!! your older sister!!!" she said and was still crying.

"It's more like I am your older brother, ahh!!!" He feels desperate to get out of her hug. "Can't…. Breathe!!!"

After that, she calmed down, even though some tears hadn't been wiped, she began to smirk a little.

"Nnn… With that smirk… What are you up to? Suisei-chan" reply by Yuki. 

"Su- Suisei-chan?!..." Suisei blushed, her expression telling that she got shy. She quickly covered her face using her hand.

"Umm, why is your face a little red, Suisei-chan…-" She suddenly shut his mouth with her hand. She was also covering her face.

"Eeek! Please don't call me by that name!!! Like usual, call me 'sis' !!!" Suisei said with a embarrassing look

"Un- Understood!"

Suddenly, they heard footsteps that sounded like a crowd, it seemed to be coming in this way., Suisei was very sure it was the enemies, she panicked

"Oh dear, someone is coming, already?!" Suisei said with a panic tone, before the crowd could see them, Suisei quickly grabbed his hand and sprint. However, their footsteps notify the crowd.

"Hurry up! Yuki-kun!!!!" Suisei said with her eyes closed, 

It reveals that the crowd was really the enemies. "Knew it!"

Suisei was running at her full speed which also made Yuki really exhausted, he drained his energy into the minimum, he couldn't run anymore. ""Huff… Huff… I am really exhausted-...", Then he slipped. "Aaa-" and fell into the ground.

"Yuki-kun! Get up-..." They were surrounded by the enemies "Oh… It's too late already?!"

"Oha, dear… If our life ends here, then, please never forget that I love you Yuki-kun!"

"Seriously? Why must this time?!" Yuki look at her with a face that telling 'This is not the time'

When the enemy was about to attack, suddenly the Cyrosland Liberation Movement came to the crowd. "Hey! Watch out who you're killing right now! Before you do that, you must fight me!" Suddenly a voice from the forest can be heard, it seems like he's speaking with the crowd's leader.

"Haa? Now, who are you? Don't you dare to mind this business!!" the crowd leader spoke with a annoyed tone

"Oh, I am the Cyroslandia Liberation army, and I was tasked to rescue the lost Cyroslandia" He spoke with a chill tone

"Hmm… sounds like you're a threat to us, huh? Ok then, you better be coming with us!" the crowd's leader spoke with a evil tone and with a laughter

"Hey! didn't I mention that I will fight!!!" he said with a chill tone

"Right… Then! Bring it on! You may or may not be a challenging unit, but we outnumbered you!" the crowd leader and the crowd are ready to fight

"This is bad… Yuki, get into that bush over there!" Suisei spoke

"Huh? Aight!" Yuki got into the bush but he accidentally collided with a person and fell "Woah?..." Yuki was shocked. "Oww… My head…", he then sees a young girl about the same size as him.

"Hu- huh?! Do- Don't get closer! Don't hurt me!!!" the little girl said with a nervous face

"Umm… Don't worry, I am not a threat! I am hiding from a threat, right sis?-" He looks around and sees that Suisei is not here. "Sis?" He looks at surrounded 

"I may join the fight too, then!" She pulls out her personal blue icy crossbow.

"That's a nice bow you got there, little kid!" The Cyroslandia Liberation army spoked

"I am not a kid, I am already 20!" Suisei spoke while pouting

"Huh? Despite your size, you're older than me?!" he was truly shocked "whatever, let's get into this battle!" The Cyroslandia Liberation army spoked

"Uhmm… Okke…" Suisei understood

They both fight the crowd, despite outnumbered, the crowd rapidly losing their number.

"Oh wow… That's how it went huh?…" Yuki sees her sister fighting, did not expected her to be able to fight

"Nnnn… Your sister is… Cool…" the little girl said, now she seems to trust him a bit

"I couldn't hear what she said though…" Yuki spoke with curiosity

While they watched the battle, they enjoyed seeing how cool they both were. Suisei, she has a pierce-able arrow, and slows the enemy as well, and also she has a good aim. Then in the Cyroslandia Liberation army, he used an assault rifle. Despite that, he targeted the weak spot on each shot, it's very effective.

After they're done, they came to the bushes

"Yuki-kun? You are fine right?"

"Yes sis!" Yuki said with a cheerful tone

"Oh right, great to meet you, my name is Mochizuki Isamu." the Cyroslandia liberation army said.

"Nice to meet you Mochizuki, my name is Satoshi Suisei." she put a slight smile

"Great to know, Satoshi!" Mochizuki said

"My name i-" Toshinari message was cut off by Mochizuki

"Hey Everyone! I recommend following me into the base, everyone grouped in there." Mochizuki said

"Nnn… Sure!" Suisei said

The girl feels pretty desperate, when Mochizuki cuts off her response. But then Yuki came near to her and said "Hey uh… Don't be depressed… Let's go!" He held her hand and moved. "Woah?"

On the way, they entered a Rainforest which also covered by Snow biomes too, Cyrosland country seems to be full of snow, but it's a bit sad that Cyrosland has been defeated.

Suddenly, they found upon a dead end, Suisei look at Mochizuki

"Are we arrived…" said by Suisei with a serious tone

"Yup!" Reply by Mochizuki

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

"Woah… this platform is unusual… Is this something a fantastic story would tell us..?" Questioned by Suisei

"I can tell that it is a plot that a fantastic story will include! Well, watch kid!" Reply by Mochizuki. His sentence was somewhat weird, is this something?

"I am not a kid…" Suisei said

They stepped onto the platform, a beautiful aura came to view, it seemed like it's processing something, they then teleported them to an island that they thought was just a fictional island. The Floating Island.

 "Woah, is this the place? It's very beautiful! Suisei replied, while Toshinari and Yuki were looking around with the amaze face

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