Don't worry guys, i will make another arc for this story.
"Nosaru! We need to stop Chrome!" Shamal says. "The power of the flame could kill her if she doesn't control it!"
"Not yet!" Nosaru answers. "The life flame can save Mukuro! I will stop her when Mukuro's injuries disappear!" A mist barrier stops her, and then she can see pictures from her past, her younger self crying holding her brother. "Get out from my head! Nero!" Nosaru's flame becomes stronger, without that the boss notices, she attacks him with her chain, Xeln's illusion disappears.
"What…!" The boss falls with his blood. "How did you…? I thought you will not attack your brother!"
"If he was really here." She moves to him. "But, my brother is dead."
"Boss!" Racer runs to him but he was stopped by a water wall. "What is that thing?" H entered into a water ball, he can't breathe.
"Sfera dell'acqua" Jim answers. "This is a water ball created by the rain flame, you will not be able to breathe." Racer finally fainted.
Nagi's flame becomes stronger, and Mukuro's injuries disappear, Nosaru runs to Nagi.
"What are you going to do?"
"All what she need is to feel safe, so I will make her feel it." Nosaru hugs Nagi, making her calm down. "The rare flames activate because of feelings, if I can make her feel safe and warm, her flame will stop."
Nagi begins to feel warm, her flame disappears, and she sleeps in Nosaru's arms.
"What about Mukuro?"
"He is alive! Thanks to Nagi's power."
Nero Forest.
"Tenth!" Gokudera runs to his boss.
"What's wrong, Gokudera-kun?" Tsuna asks his friend.
"We…" Gokudera says in disbelieve. "WE WON!"
"Are you sure?"
"Yes." Gokudera answers. "Shamal called me, the Nero boss and his guardians lost the battle, it ended."
"Finally!" Tsuna says in joy. "It's over!"
Three days after the end of the battle. Namimori Hospital.
"Eh?" Nagi opens her eye, she was in the hospital. "Why am I here?"
"You finally awake." Nosaru was in the room. "You have to be happy, the war is over. Vongola are winners."
"But…" She says sadly. "Mukuro-sama is dead."
"No."
"Eh? What do you mean?"
"He was saved." She answers. "Everyone is okay, unlike the first war, no one died."
"So, it finally ended." Nagi says in joy.
"Yeah." Nosaru opens the door to left the room. "By the way, if you need something, you will find me at Kokuyo land."
"But, I can't come back…"
"Nagi." Nosaru cuts her sentence. "If you think that you will not be able to face Mukuro you are wrong. Mukuro was saved thanks to you."
"H…How?"
"I don't think you need to know now. But, no matter what happens, I will always be here for you."
"Why are you doing this to me?"
"Because I want to do it." Nosaru smiled to her then left the room.
"Thank you, Nosaru-san."
