They were slowly arriving un undetected thanks to Juvia's water magic covering them as they slowly approached the tower..
Meanwhile Erza was chained to the stone wall in a prison cell and remembering some bad memories of being a slave in the tower of heaven as she listens to Sho's nonsense as he was laughing like a maniac before Erza knocked him ouy and requiped to her armor to go after the one responsible for this... Jellal..
Meanwhile everyone outside was thinking of a plan to get in to save Happy and Erza before Juvia told them about a cave that is underwater and Y/n nodded
Y/n: "It's a good plan but how will we get down there. I haven't had much training underwater so my lungs aren't cut out for it."
Juvia smiled as she shows a sphere of water with air bubbles in it
Juvia: "Then use this it will help the four of you breath underwater."
Y/n: "Cool, nice thinking Juvia."
Juvia soon blushed at Y/n's comment as they soon went a head and went underwater to what looks like the inside of the castle as Y/n was getting his top gi back on while looking around as the others were looking before they got spotted and troops started to come at them so all 5 of them started to fight them all as it was too easy even for Y/n to only use his bare hands and they explore to they saw a room full of food and Y/n and Natsu already started to chow down on the food
As they kept eating till there was no more and they heard more soilders run into the room but before they could fight someone already and surprisingly it was Erza who defeated them. But during when they finally talked to Erza she instructed them to go back far away from the tower and of course Natsu protested and went after to go find Happy before Erza could stop him. But as they kept talking to Erza telling her she isn't alone on this and that they we're her friends but it changed when they saw Erza crying then she talked about her past of being in the tower when she was a kid and how rough it was for her, but as they talked two of Erza's old friends showed up and had a small reunion as Simon looked at Y/n and noticed his tail
Simon: "You have a tail as well as Vegeta."
Y/n: "Yeah so what that I have a tail."
Simon smiled as he looked at him knowing that destiny was calling to him to fight but they soon head out to go look for Natsu and Happy so they split up to look for the others but they listen to what Jellal had to say making Y/n clench his fist roughly and began to walk
Erza: "Y/n where are you going?"
Y/n: "I'm going to find someone that can help us."
Y/n said as he kept walking when one of the soilders tried to surprise attack Y/n he was meet with a fist punching him so hard he flew out of the tower and into the water when he soon smelled smoke and see's Natsu flying his way to the top
Y/n: "You sneaky son of a bitch."
Y/n said before jumping out of the window and began to fly after Natsu but sadly it lasted for a little bit of time before a flying bird man crash into him knocking him back into the tower but in a rook with cages and Natsu was their as well
Y/n: "Natsu, Happy you okay there?"
Natsu: "Yeah me and Happy are fine"
Natsu said before Simon showed up where they are at and the giant bird guy showed up and Natsu tried to fight the giant bird man and Y/n joined as well tryijg to fight as well as he was charging up a Kaioken Kamehameha but before he could unleashed the attack the bird man hit him but thankfully he had his power pole as it extends and he hits the bird man's head knocking him out as they soon manage to get away as they were walking the stairs up and Natsu was of course being sick from being carried but they quickly made their way to the top meanwhile Erza was there seeing Jellal and Vegeta in the room and for the others on the boat they were arguing about something until Happy yells at them
Happy: "SHUT UP!!! I know that Y/n and Natsu will bring Erza back! That's what Simon told me! If the Saiyan's true power awakena, even Jellal wouldn't..."
Everyone looked at Happy when they say that when Simon explained what Erza was trying to do against Jellal using the council's Etherion against the tower bringing Jellal down with them making Natsu angry demanding where Erza is as Y/n started running to the very top.
While for Erza she was busy fighting Jellal and Vegeta and things weren't looking good for Erza as she was soon trapped within a sphere and Jellal was walking away before Vegeta smirked and charged up one of his attacks
Vegeta: "Galick Gun!!"
Vegeta yells as he shot the Galick Gun at Jellal while Erza escaped
Jellal: "Vegeta I figured you would betray me but now its going to end anyways."
Jellal said as he was attacked by Erza and pins him down as they have their talk before the Etherion was fired onto the tower as everything was a blinding flash of light before revealing the tower of heavens true form...
