They were actually divided into two groups, on the Summerfall island is Luffy, Zorro, Robin, and Sanji while on the Winterspring is Nami, Usopp, Chopper and Law. Franky and the samurais are left to guard Sunny.
At the Winterspring
"So, where are we going exactly?" asked by Nami
"Let's find someone and ask for some help…" it's Usopp
"It's creepy here and cold…" said Chopper, then Law turn around.
"Don't move!" he screamed and suddenly the three froze up, looking at their surroundings
"Hey! What was it Law?" Nami questioned
"You will give me a heart attack OMG!" Usopp cried while chopper was embracing Law's right leg
"Someone is watching us…" Law said in such a serious tone…
"EH!!??" The three once again cried in chorus, and then red eyes glow in the shrubs. They position themselves and ready to fight when….
"AAAAHHH!!!" the shrubs grab their feet Nami was hold down by the shrubs dropping her weapon, Usopp was caged and his hands and feet are tightly captured while Chopper still embracing Law's right leg was being turn around with his moves as he tried to cut the shrubs approaching him
"This is sh*t!" Law cuss as he saw his fellows being captured, slowly he can feel the cold that makes a drop of sweat from him
"Hehehe, intruders, the Princess will be glad" a young man who is the reason for controlling the shrubs showed his self
"Who are you?" Law asked
"I am the guardian of the Winterspring island and intruders from the Summerfall are prohibited here, you must be an alliance who wants to kill the Princess, and I won't let that happen!" then the young man attack him
On the Summerfall island
"Tsk… I never expect this to happen…" Zorro is quite pissed off
"The island says it, they really gave us a warm welcoming" said Robin
"Wow! T~his Fhood ish so~~ Yu~~mmy!" Luffy who is eating a luncheon meat
"Hey, we are not here for trouble, we just wanted our trapped boat to get off and leave tell me is there anything that we can do?" ask by Sanji to the soldiers they have beaten
"Eh, where is the exact location intruder?" The wounded soldier ask
"It's in the middle of the island the exact boundary of the two" Robin said
"I'm sorry but, you will be trapped there forever and you will not be able to escape this island HAHAHAHA" and he let a creepy laugh that pissed Sanji and throw him a kick
"NAH! You're useless! So what's the plan Luffy?" he called to Luffy who is quite busy eating the food of the soldiers in the long table, when
"And who are you intruders making trouble in my kingdom!?" suddenly a girl in fierce red and orange gown attire showed up, she's holding a golden sword and a shield, she got a long red orange hair all tied up and a blazing blue eyes.
"Kingdom?" Robin asked
"I'm the one asking you intruders! Now answer before I kill you right on where you are standing!" the girl exclaimed
"Hey! Respect her, she is the Princess of Summerfall island!" the soldier said to Sanji whose nose is already seeing the young fierce girl
"OMY ! Such a lovely lady! *Ehem* (starts to act so handsomely) My dear princess, sorry for intruding in your kingdom, we are not here for any trouble, we are just roaming around and looking for her when these ugly bastards start throwing us their flaming arrows" the girl was quite convince and look at her beaten soldiers
"No! No! Your Princess! It's that straw hat guy that started he attacks and eat all our food!" pleaded the soldier
"We are indeed sorry for that, it's just our captain Is so hungry" said Robin, "We were like to ask for a help to get our boat trapped in the middle of this island"
"I see… I'll be helping you intruders, but it would never be easy to do what you wish for"
"Huh? Why is that so? You said it is your kingdom it will be easy for you, just call your men to work on it… " said Zorro who is getting bored, and grab a bottle of wine
"This is Four Season Island, and is divided into two, you are now in my territory which is Summerfall, the other one is Winterspring which is not under my control… and the place you're saying that your boat is at the Winterspring terrain" explained the fiery girl
"But you said it was the boundary?" Sanji asked
"Frydz's territory overlaps already and once we lay our feet over the boundary will set an all out war between us"
"Eh? I don't understand much, what is Frydz? Is that a food? Does it taste good?" Luffy ask so suddenly
"Frydz is my twin sister, she reign the Winterspring Island, BTW I am Erydz Summerfall." The fiery girl finally introduced her
"I see, she is your twin sister right, so why won't you talk to her? You're sisters anyways…" Robin suggested
"I may, but knowing Frydz, she has changed a lot…"
"Can you tell us about her?"
...
"Ah! Sh*t!" Law cried as Chopper tries to heal his wound
"Easy, the pain will ease soon when the medicine takes effect… we were lucky that we were able to escape those creepy people!" Chopper wipes the sweat on his forehead as he was finish with Law's wound
"You intruders must be careful, you don't know what's with Winterspring island!" said the old man who happened to help them and let them stay in at his cabin for a while
"We are going pops, thanks for letting us in…" Law said and was about to get out of the door
"Wait! Law-kun! Your wound is not yet healed" Chopper called
"Be careful young man… If you want to escape alive, you must melt the princess's heart" said the old man
"Huh? What about that?" it got Law's attention
"Years ago, Winterspring aren't that cold and frozen until the Princess of this island got lost… and when she return, the whole island change and starvation and thirst arises as the whole island turned out like this… an island of crystal"
"You mean pops, the island is not like this before?" Chopper asked
"Yes it is not, we have also have summer and fall, but after that incident only winter and spring left here… and the Princess set a war against the neighboring island"
"Huh? So there are two princesses reining this four season island?"
"Yes, the twin Princesses were set to rule both of the island but then when the Winterspring princess got lost and returned back it all change and they never get settled with the Summerfall princess that later on makes the gap even higher until they started a war again each other, the other princess and their kingdom cannot lay a feet on each other's territory…" explained the old man who looks so sad, "Only if the real Winterspring would come back…"
"What do you mean?" Law finally speak up
"I know the little princess very well… I know that something is wrong that frozen her heart and changed her a lot… it's like something is causing a spell under her"
"How sure are you?"
"I know my instinct is right… so please, young man once you see the Princess, make her cold heart melt to bring back the peace in Four Season…"
"It's not my duty to do that… and besides my goal is to get our ship out of the middle of this island and get to Dressrosa as soon as possible…" and he left the cabin
"EEH! Law-kun wait for me! Sorry pops, and thank you! Don't worry if we were able to do something we'll help, I know that our captain will hear your favor… thank you for your kindness again!" said chopper
"Thank you too and welcome… ah wait there's something I must tell you"
…..
Fast forward…
…..
Law and Chopper are walking in the woods, Chopper is keep on bugging Law to help the old man…
"I said we should get out of this island soon so we were not going to waste our time"
"Ah… if Luffy was here he would hear that old man's small favor…" Chopper just sighed because he can't do anything else
They were about to reach the small lagoon, when ice spikes almost hit them
"Who's that!?" law shouts
"Intruders… what are you doing in my territory?" a cold tone of a woman echoes, the two search for where the voice came from, and the ice spikes keep on attacking them… chopper got trapped in the ice spikes that came out from below,
"First the Shrub guy and now ice spikes! What are these sh*ts happening!" Law can't stop cussing around
"Intruders from Summerfall must all die, feel your cold death strangers" thousands of spike was about to hit law his eyes widened
"ROOM!" he screamed
In just a split of seconds the situation changed, Law successfully turned the spikes back to the enemy, so now the enemy was lying at the ground with left arm bleeding
"You're a bastard! You must die intruder" still with the emotionless tone
"LAW-KUN!" Chopper called, but Law knows what he's doing and the time he saw the real face of the enemy he knows what to do… he cuts the enemy and get its heart, and tear the body into pieces Chopper's eyes widened to see what the guy did, now the body of the enemy all shattered on the ground and is now gripping to live
"Da-damn you! H-how did… you f-find out… I-I'm going to…t-ake revenge…" before the shattered body melted on the ground and turn into waters…
"Now, what are we going to do with this?" Law asked holding the heart, and pointing to the unconscious girl lying on the ground
"Law-kun! The old man is right! The Princess! You've save the princess!" Chopper runs to the girl to see if it still breathing, "The pulse is too slow but she will managed it" just a few medication the girl finally opened her eyes, the first thing she saw is the image of the impatient Law waiting for him to wake up and Chopper whose eyes looks so relieved
"W-who are you?" her face flushes as she see the two
"I am Chopper, and this is Law, we saved you from being trapped in the body of a weird creature devouring your mind and heart" he explained
"A creature? Devoured?" she is still clueless, "I can't remember anything…" she held her head, Chopper give her some pain relievers, and discussed what happened, how did Law saved her
"I see… Thank you for your kindness… I owe you my life and as well as my kingdom's life from the evil creature who tried to take rule of me… Especially to you Mister…" She shyly look at Law who is not looking at her, she was wearing Law's clothing jacket to cover up her nakedness, Law still not looking at her held out the heart he stole before
"Here, this is your heart, the old man says that to be able to defeat the creature I must stole the heart first so that the bind between you and the evil creature will be broken… I'm giving it back to you…" he said, but the girl shook her head, Chopper and Law look at each other
"No, it is all yours" she said
"WHAT!?"
"It is the Four Season rule that once a Seasoner (The people of the island) was saved by others, everything that they own and they possess will be all owned by the person who saved them… so that means, you saved me, and my heart that you stole will be all yours as well as me" she explains and look straight to Law's eyes
His jaw dropped as the young girl stand up and kissed his lips
"I am Frydz Winterspring, the 1603th Princess sealed the golden rule and now all yours Trafalgar Law."
