Chapter one – New enemies
'Ah! I'm about to be chakra depleted.' Satsuki thought while panicking. 'If I don't have chakra, my secret will be revealed. I need to convert it into chakra.' He channelled it and rapidly turned it into chakra. 'I have now at least one quarter of my normal capacity, good enough.' He tsked, 'I should never have healed Sasuke-teme.'
A loud scream tore Satsuki from his thoughts. Naruto. No, not him. He dashed in the direction of the shout and he thought his heart would stop. Naruto had been injured, and not some minor wounds but a really serious one. Madara had engaged in a battle with Naruto and had been able to severely injure Naruto.
"Sakura!" Naruto shouted. Satsuki's first thought was 'I hate this name', and the second was 'I have to save him!'
Satsuki dashed towards Naruto. He arrived to where Naruto was lying right next to Sasuke; the blonde's breathing heavy, and Satsuki's hands lit up with green medical chakra. He scanned Naruto's prone form and he became more worried. 'He has six bruised ribs, one broken which has punctured his left lung; his right femur and his tibia are broken. He also has inhaled quite a bit of smoke…'
He had to heal Naruto quickly. Hinata, who had followed Satsuki, had been battling with Madara and was been overpowered by the older shinobi. Satsuki set to work and had healed Naruto in record time.
"Hinata! Go and look after Naruto!" he shouted. The girl jumped back and he punched the ground with a chakra-laden fist. Both he and Madara avoided the rocks which went flying due to Satsuki's punch.
"Nice hook little girl," Madara commented, smirking.
"I'm not a little girl, you old bones!" Satsuki roared. Madara's eyes widened slightly but he smoothed his features into his cold smirking mask. Suddenly, Kakashi appeared in front of the Slug Princess' apprentice.
"Sakura, I need you to help Obito. He needs medical care," the jounin said. Satsuki glanced back at Madara. He then healed Kakashi and whispered, "Distract him, okay?" and got up and ran to Obito.
"Hi Tobi! How are you? Chakra exhaustion, right? Ok, I will channel some of mine to you so please, do not fight against it," Satsuki said while setting to work.
"Saki-chan… You don't hate me?" Obito asked.
"Why should I? You have done what you thought was right, so no," the medic answered.
Minato asked "You know each other?"
"Yeah, kind of…" replied the other ninjas in unison.
Several seconds passed in silence, apart from the sounds of the battle. Satsuki removed his hand from Obito's chest and sighed silently.
"You are out of danger but you will need rest," Satsuki informed the Sharingan user. He turned to Minato and asked, "Can you make sure that he is not injured please?"
Minato simply nodded and Satsuki took off to where he left Naruto. He asked to Hinata, "How is he doing?"
"H-He should b-be alri-alright," answered the shy girl.
Satsuki nodded to her, "Nice job." Hinata, astonished, simply stared at him.
"I will help Kakashi-sensei, okay?" Satsuki said and he jumped into the battlefield again. He adjusted his gloves and ran next to Kakashi. The older jounin glanced at him but said nothing. Together, they rushed towards the co-founder of Konoha.
Satsuki threw some shurikens at Madara but the latter dodged them. Kakashi's hands flew into multiple of handseals and he shouted, "Suiton: Water Dragon Jutsu!"
A giant stream of water in the form of a dragon charged towards Madara. He counter-attacked by using 'Katon: Fireball Jutsu'. The two justus collided and steam was formed. Meanwhile, Satsuki was preparing his next attack. He had only few seconds to make eighty nine handseals. But before, he had to drop his genjutsu. He was using too much chakra. He dispelled it and started the very long sequence of handseals.
After the steam dissipated by a creative use of a Futon jutsu of Madara, Satsuki looked at him in the eyes and whispered, "Tears of a Demon, Binding." Madara stood there immobile with a slightly dazed look. A solid looking rope of chakra appeared in Satsuki's hand and he manipulated it to fasten itself around the Uchiha.
Then, silence…
Satsuki glanced around, anxious. 'Why no one is reacting? Have I done something wrong? Have I changed that much?' As he was thinking, one knuckle head ninja and an emo one were regaining consciousness.
The blonde jumped to his feet and shouted, "Madara!"
Sasuke muttered, "Shut up, usuratonkashi."
The two looked towards the battling ninjas and gaped.
"Did Kakashi-sensei defeat the Madara?" asked Naruto.
"N-No Naru-Naruto-kun. It w-was Sa-Sakura-s-san," answered a very red Hinata.
"That useless girl? I doubt it," scoffed Sasuke.
Angry, Hinata whispered louder than ever with Naruto in the vicinity, "Sakura-san is not useless! Without her, half of our forces would be dead! And Madara would not be captured!"
Sasuke brooded silently.
"Is Sakura-chan injured?! I'm gonna kill that bastard if he hurt her!" exclaimed Naruto.
Hinata blushed slightly but whispered firmly, "Naruto-san, if you look there, you would see that Sakura-san is perfectly healthy."
In the battlefield, Satsuki noticed that his teammate and ex-teammate were awake and apparently well enough to argue with Hinata.
He shouted, "Kakashi-sensei!" and tossed the chakra rope to the silver-haired shinobi.
'Nice to see that Hinata has gathered enough courage to talk back to Naruto and Sasuke,' he thought.
He was concentrated on his thoughts but was still aware of his surroundings. He felt two very familiar life forces coming towards him. 'Crap! These two know that I dropped my disguise!'
Suddenly, a beam of light hit Satsuki in the middle of his back. His eyes widened slightly and they suddenly lost all their light.
Meanwhile, the other ninjas, who saw the pink-haired shinobi (who they saw as Sakura, the sweet but temperamental kunoichi) defeat The Almighty Madara be hit with that strange beam of light. They could only stare at him, still shocked.
Two persons appeared with loud cracks, a man and a woman. "You little bastard! You shouldn't have done this!"
To be continued.
