The air balloon ship was moving towards the Kazahana castle and unknown to them Scarlet was following them.
Inside the ship,
Koyuki (Yukie) was sitting on the sofa inside the ship, there was a table in front of her which had some wine and water kept on them. Doto was standing in front of Koyuki as he said "You have grown quite beautiful Koyuki, tell me little princess do you have the hex crystal with you"
Koyuki replies "Yes"
Doto replies "Good, it is the sole link to the Kazahana clan and the key to opening its treasure"
Koyuki asked, "Key to what?"
Doto replied "When I took over this land from your father's hands Kazahana clan's resources were all gone. Sosetsu must have hidden his riches somewhere, I searched for a long time and finally found it. It is hidden deep within the rainbow glacier, it has a key there which can only be opened by the hex crystal. Once I get the possession over the treasure the land of snow will gain military superiority over the five great nations"
Suddenly Naruto's voice interrupted "Not going to happen"
Koyuki was shocked seeing the arrival of Naruto, Doto asked: "How on earth did you get here?"
Naruto replies "Never underestimate a ninja"
Naruto was then tied with ropes and then knocked out by Mizore. Suddenly many of Naruto's shadow clones appear tied from the lift.
Nadare kneels and says "My apologies my Lord as you can see this brat was handful"
Doto replied "Well he knows the Multi shadow clone jutsu"
Mizore says "Well he does have a large amount of chakra"
Nadare says "What do you think maybe we should try that contraption out on him"
Doto replied "Hmm He would make an interesting test subject"
Nadare brings a device and keeps it on Naruto's dantian, suddenly Naruto feels that his chakra has vanished, Naruto felt tired, his shadow clones disappeared.
Doto: I will take the hex crystal if don't mind.
Koyuki takes out the hex crystal and gives it to Doto.
Doto takes the hex crystal and frowns he shouts at Koyuki by holding her collar "This isn't a game do you think I don't know this a fake"
Koyuki replies "No it is impossible … Kakashi Hatake"
Nadare: Makes sense, Kakashi is a shrewd ninja he probably used it as a bait.
Fubuki: Don't even worry about it we will have him rounded up in no time.
Doto: Why even bother the man will show up soon enough until then why even bother.
The air balloon arrived at the Kazahana castle, Scarlet was hiding outside the castle. She watched them go into the castle, Scarlet stopped and restored her Chakra to the peak, and she used her power of space to make an outline of the no of enemies in the castle.
Scarlet observed that the castle had first six floors in the form of a dungeon, there were many prisoners in the dungeon which included Naruto and Koyuki and there were 100 men guarding this dungeon. She also saw that Doto and his three snow ninja were on the tenth floor. The seventh, eighth and ninth room contained empty bedrooms which were guarded by 12 men.
After she was done with the calculations she held a kunai in her right hand and held some shuriken in her left hand. She strode towards the castle, her eyes were bloodthirsty and cold completely different from the usual poker-faced Scarlet.
Scarlet rushed towards the guard standing in front of the gate and slit his throat with kunai and then appeared before the guard beside him and slit his throat, she then threw one shuriken each on the guards at the corner of the building, and the shuriken pierced their head causing their death.
Scarlet recorded "Outer guards eliminated"
Scarlet sees that there were six guards in between the castle gates and castle. She used transformation jutsu and transformed herself into one of the guards she killed, she then swiftly killed one of the guards and threw his body into the bushes and replaced him.
She then made a shadow clone and transformed it into a shuriken, she threw it onto the guard parallel to her. The shuriken instantly transformed into Scarlet and she slit the throat of the guard and transformed into him using transformation jutsu.
Similarly, she killed the remaining four guards and went near the entrance of the castle. She then once again remembered the number of people and their position in the dungeon. She used shadow clone jutsu and created 50 shadow clones, she took 5 shadow clones along with to the floor in which Naruto and Koyuki were present while the remaining clones were silently killing the guards in remaining 5 dungeon floors.
Scarlet swiftly moved towards the prison in which Naruto was present and killed the guards who came in the way. She stopped at Naruto's prison while shadow clones went forward to kill the remaining guards. When she saw that Naruto was continuously getting electric shock because of the strange device on his stomach, a terrifying killing intent burst out of Scarlet. Koyuki who was in the opposite prison felt suffocated.
Scarlet quickly took the keys from the guard she killed and opened the gates of the prison. Naruto said "Am I dreaming? Why I am seeing nee-chan here?"
Scarlet took back her killing intent and replied with a petting voice "What dream are you talking about Naru chan, I came to rescue you"
Scarlet then broke chains which were holding Naruto, Naruto hugged Scarlet as he said "Nee-chan I want to kick that Doto guy's ass"
Scarlet replied "Leave him to me Naru chan, all I need you to do is protect Yukie"
Scarlet went towards the opposite prison where Koyuki was imprisoned, she quickly unlocked the prison and Koyuki came out.
Koyuki said "To be honest I was not expecting you to come"
Scarlet replied "I never abandon my comrades Koyuki san, from the moment you joined my Organization you are under my protection"
Koyuki asked "Then why didn't you save me back then when I was captured by Doto"
Scarlet replied "Remember I promised you that I would destroy everyone related to the death of your father. If I killed Doto back there his subordinates would most like escape so I had to make sure that all of them were present to kill them in a single swoop."
Scarlet's shadow clones just returned back after killing the guards.
Scarlet said "Now that the guards in the first six floors are eliminated, you guys go to the seventh, eighth and ninth floors and kill the guards. We will go to the tenth floor and take care of Doto"
Koyuki's mood was very chaotic on one hand she felt scared by hearing about all the people killed by Scarlet and on other hand, she felt very happy that the people responsible for her father's death are finally getting their retribution. No matter what she felt a lot of gratitude towards Scarlet who is helping her avenge her father.
Scarlet, Naruto and Koyuki went towards the tenth floor.
