The Golden Fairy (Dragon Ball Z and GT X Fairy Tail )

C6 Trip to Galuna Island

It has been a Week since Goku took Natsu and Gray as students and the only thing he could say that he was proud of their progress so far, Both Dragon Slayer and Ice Mage have already adapt to the 150 Pounds Shield they have on their back in 5 Days, they asked if they could increase the weight of the Shield, The Saiyan God with his Ki increased the weight making it 300 Pounds, Goku was impressed of how far they were pushing themselves to overcome the weight of the Shields, they have been training nonstop Physically to the point of collapse

Goku of course made his students to do chores without any tools or magic around Mangolia taking mission of Chores, the guild members asked both mages why they were wearing Shields in their backs only replying back saying it's part of their Training for the S-Class Trials, in just a week they manage to finish 50 Missions of Chores around Mangolia

Also when they don't do Physical Training the S-Class Saiyan stared to teach them the way of Martial Arts, at the beginning they couldn't understand why they needed but Goku simply told them that they don't have a style of fighting to not waste Magic, In a week they manage to take down the basics of the Turtle Hermit Style, When Goku was not around Natsu challenges Gray for a spar in Hand-to-Hand Combat to get better and see who was the best between the two of them, For now they can say their training is paying off since they have gotten stronger with the endurance they have been through in a week, they were confident that if they take off the Shields they could beat Erza on a 2vs1 but they would definitely tied or lose without making the Titania struggle on a 1vs1 so that's why they keep going with their training to get stronger

Now we see Goku looking at Natsu and Gray who were sitting in Meditation stance, they were excited since now they would learn how to unlock Ki and it's basic

Goku: As I explained in the day when we fought Eisenwald, Ki it's part of our Daily Basis, it's different from the magic that you guys use but Ki it's more destructive than Magic itself, right now I want you to find you're inner Ki and bring it out between you're hands *finished with a smile*

Both Mages nodded it and stared to concentrate within themselves, Gray felt the heart beats where he could see his Magic being concentrate, he looked more deep down within him and then he felt something warm it wasn't Magic, it was his Ki itself, he stared to concentrate more making him sweat and he brought a little bright light in his hands, Gray turned around to see Natsu that he made it too but it was more brighter he just 'Tch' meanwhile Natsu just smirked at this, Goku was smiling of how proud he was right now, after their lights disappear they stumble down breathing hard

Natsu: Damn... *Breathing Hard* I feel like I have been running all around Fiore non stop

Gray: I have to agree with you this time Flame brain... *breathing hard*

Goku: If you guys keep training with you're Ki and how to develop it, it will give you different Abilities that will be useful in battle but don't rush it, if you use to much ki it can be dangerous *serious expression* Well guys it's almost Lunch so let's go to the guild and maybe grab a mission *smiling*

Both Mages smiled and went towards Goku and grabbed their shoulders, the Saiyan God stared to concentrate towards the Guild and disappeared in a instant with his students

Scene Change... Fairy Tail Guild...

Everything was normal today in Fairy Tail, Natsu and Gray having their Rivalry discussion trading fist into each other making a Brawl happen, Lucy was sitting with her friend Levy talking about stuff, Makarov was sitting on the Bar stance watching everyone enjoying themselves, Goku was eating like a Maniac, Mirajane was watching with a sweet smile at the Saiyan God, she could say that she has a crush on him but that crush it's developing into something stronger, Erza was eating her cheesecake near the Bar Stance where Marakov and Goku were, but she had another things in mind regarding of what type of training was the Saiyan God giving Natsu and Gray, she could tell they have gotten little stronger than last week and she notice they always wore those shields, what made them so special?
