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

C21 : Team Natsu Training! The Festival Battle Begins

Outside's of Magnolia.. Goku's Training Ground..

The Super Saiyan God was with his eyes closed in a deep concentration, To his sides he could sense Natsu and Gray in their Kaio-Ken X2 Form staring at their Master with determination, Both of them nodded to each other and they dashed at fast speed that could be a blur for normal people, Goku opened his eyes and Blocked both of their attacks with one hand blocking them, The Ice Mage just 'tch' and gave an Axe Kick in witch Goku blocked with ease but he didn't saw Natsu giving him a powerful punch in the chin sending him few meters away..

The Saiyan God just smirked at this and stared to Move at Lightning speed making both of his students having to struggle to keeping with him, Then Natsu felt a punch in the stomach making him cough saliva, he looked down seeing Goku's fist in his stomach, The Saiyan didn't waste any time and went for the offensive throwing at Natsu a Ki Ball in witch the Dragon Slayer responded back with also a Ki Ball, when both of them make contact it created a Explosion covering both if them..

When the Explosion died down we could see both of them in a series of punches and kicks at fast speed not giving an inch in their attacks, The Ice Mage got tired of this and went at Hyper-Sonic speed towards them also giving a barrage of attacks making Goku now blocking both of their attacks at the same time but with quite ease

Goku: They have gotten better this past 2 Weeks *blocking his attacks with ease*

Then he looked at his side where the battle was not taking place, He saw Erza and Lucy in a meditating position training their mind, 2 Weeks ago after Goku came back from his encounter with Ultear he saw Lucy and Erza coming up to him asking him for Training to unlock their Ki's and be stronger, Their reason were that Erza wanted to fight side by side with him and not be helpless as she was in the Tower of Heaven and Lucy didn't want to be the dead weight of the Team and not rely on her Celestial Keys all the time, Goku gladly accepted the request and stared to train them also

Lucy was the first one to take down the concepts of Ki faster than Natsu and Gray did since she was great at controlling her energy and Erza took 3 Days to awake her Ki to use it in Energy Blast, even if she had a stronger Ki than Lucy she lack the control of it making her weak after using it, Goku also trained them with Gravity Seals to wear, Natsu and Gray are wearing a 5X Gravity Weight, Erza was Wearing a 4X Gravity Weight and Lucy a 3X Gravity Weight..

He also taught Lucy and Erza the Kamehameha in witch both of them got it down at the same time bit it wasn't as strong as Natsu and Gray, he also taught both of the Girls Kaio-Ken in witch both of them really struggle for the great strain in their body and took a week to unlock it, Lucy could handle it for 1 minute and Erza could do it for 2-3 Minutes, Goku said to Erza that even if she was stronger than Natsu and Gray in magic she was weaker in the concept of Ki for now but he was sure that both of the girls will reach greater levels of power

Goku: I can see their Determination in their eyes, they want to get stronger to not suffer.. *smiling and still blocking their punches with ease*

The Only student he knew was putting most work was Natsu, After knowing that he can go Dragon Force he has been training non-stop and trying to achieved it again, He manages to go back in that form a week after they came back but by thinking bad stuff like Igneel abandoning him and the Death of Lisanna and Simon, Goku thought that Dragon Force was like Super Saiyan in the beginning for him when he was trying to control the colossal power he was now possessing, He is going to help him after he could go his own and train him the way he did with Gohan in the Hyperbolic Time Chamber

(A/N: Natsu and Gray are Tenrou Island Level in their base form, With Kaio-Ken X2 they are GMG Level and Natsu in Dragon Force he's at the level where he came back from the 1 Year Time-Skip after Tartaros arc)
