Brain has make (Y/N) use her power to make Nirvana move, out of her own will. (Y/N) is in pain, and she try to break the spell or call one of her spirits, but she can't fokus. As for Nats, has Happy got him and they are both looking at the old Nirvana city. 

''This smell... It's his smell.'' Mumble Natsu. He take one more snif and get a familiar one. ''Oh crap, (Y/N) is near that guy.'' Panic Natsu.

''Wait, is (Y/N) with Cobra and Brain? Up there?'' Ask Happy.

''Yeah she is, and now that I listen, can I hear her in pain. Happy fly over there.'' Natsu pointed towards the tower in the middle.

''Aye sir.'' For Natsu, is (Y/N) a little sister. She is important to him, to all of Fairy Tail. Hurt her and you are getting a fight with the guild. Brain has activated something, but (Y/N) is the one who is making the whole city move. Natsu get's ready to fight and safe her.

''I am gonna stop ya.'' Natsu ready an iron fist, but he missed.

''It's you.'' Muttered Brain. Natsu spot (Y/N) beside Cobra and get's angry.

''Roar of the Fire Dragon.'' Chant Natsu. He know (Y/N) can handle it without getting hurt. Brain make a shield and protect himself and (Y/N).

''Cobra. Don't let him interfere.'' Order Brain.

''Right. Cubellios.'' Cobra's snake attack Natsu from behind.

''You. I'll burn everything.'' Cubellios send Cobra flying up towards Natsu and hit him before Natsu could use his fire magic. ''Thank you, Happy.'' Before Natsu make another spell, does he spot Cubellios get wings and fly with Cobra in it's back.

''What's that? The snake is flying.'' Says Happy while Natsu is freaking out.

''Hey, I heard that you couldn't handle transportation...'' That piss of Natsu.

''Happy isn't transportation.'' Yelled Natsu.

''That's right.'' Agreed Happy.

''I see. So that's why you were already flying. Because you aren't able to stand on Nirvana. You are a riot, buddy.'' Says Cobra.

''That's none of your business, jerk. Anyway, what are you doing to (Y/N)?'' Cobra take a look at the girl.

''Her powers is now the source for Nirvana to move.'' Cobra smirked at Natsu.

''Jerk. Move it, cause I am stopping this big pile of junk and safe (Y/N) from your dirty hands.'' Cobra doesn't seems feared enough, but want Natsu to go ahead. Natsu really intend to hit Brain, but Cubellios use her tail to hit Natsu with.

''I can hear your movements.'' Says Cobra. (Y/N) hear what is happening, and open her eyes. 

'I can do it, just get energy enough to do it.' (Y/N) takes a deep breath and open her mouth.

''What?'' Ask Natsu.

''Natsu. Use his talent against him.'' (Y/N) didn't have enough energy to explain all of it, but she hope that Natsu will understand her.

''Shut it, girl.'' Brain stomp on poor (Y/N) on her head. Natsu try to hit Cobra, but nothing works on him and he can't descover what (Y/N) mean by using his talent against him.

''Damn you. I'm getting fired up.'' Shouts Natsu.

''Huh? Look at that, Natsu.'' Happy notice something near Brain. ''See? The Magic Circle is back to normal. I thought your last attack erased it...''

''Witch means that unless we beat up Mr. Smarty Pants, it's no use.'' Added Natsu. Cobra chuckle at this.

''I can hear you. I won't let you.'' Says Cobra. (Y/N) watch Natsu get beatet up. That Magic circle is also making Nirvana move, so if (Y/N) could get of her own spell, then Nirvana gonna slow down a little. (Y/N) need to help her friends, her family. Only one person could get of if needed and can break this spell.

''What are you smiling about, girl?'' Ask Brain and watch (Y/N) smile more brighter.

''Just a friend who will help his princess in need.'' (Y/N) take another deep breath. This may also effect Cobra's hearing. ''Demon, help me.'' (Y/N) shouts. Natsu and Cobra stop fight and take a look. One of (Y/N)'s key shine a really dark aura. A mist surround her and one person appeared beside her.

''I don't like my dear princess in chain.'' Demon undo the spell over (Y/N) and lift her up. Brain try to stop him, but his power doesn't work on Demon. An emotionel face turn to look at Brain, but start flying with (Y/N) in his arm. ''I let you get these guys for princess, Natsu. Fight for her sake, she lost some magical power.''

''My pleasure.'' Smirked Natsu. Demon fly over the ruin city.

''I am glad you came.'' Mumble (Y/N). Demon smile a little, but not for long.

''Remember that we spirits promised to protect you, even if you can't open the gate.'' Was all Demon said before landing on the ground. Gray, Lucy and Jura watch Hot Eye and Midnight fight.

''(Y/N).'' Lucy spot the frail girl on Demon's arms.

''Just let her rest for a few minutes, and she can fight again.'' Lucy nodded to Demon and take (Y/N) in her arms.

''Let's do what Richard says and get to that tower.'' Says Gray. Jura take over (Y/N) and start running. Something fall down from the sky and explosion comes.

''Somebody is fighting.'' Says Jura.

''That's pretty impressive...'' Says Lucy.

''Which means it's...'' Says Gray and Lucy nodded. It's Natsu.

''Stubborn as ever.'' Muttered (Y/N). ''He is fighting Cobra, and can't do the most simple thing to stop him.'' When (Y/N) said that, does she spot Natsu and Cobra falling from the sky. A mighty roar sound is filling the air. ''He figure it out.'' (Y/N) smirked.

''What is that noise? A roar?'' Ask Gray. Lucy is panic behind him.

''Some kind of giant monster?'' Ask Lucy.

''No... That's...'' Mumble Jura.

''Like I said. Use his talent against him, witch mean make him feel pain in his ears.'' Says (Y/N) and get down from Jura's grip.

''How did you know that would defeat him?'' Ask Lucy.

''At the first fight, didn't I do much, but I did get a little more information about his hearing. Out of no where pop the plan to defeat him in my head and I shared it with you with that message. It's like someone told me everything I needed to know to defeat them. It's hard to explain more.'' (Y/N) look up at the tower. This fight isn't over.
