Next day....

Outside the house, the group are gathered in front of Natsu, who is looking at them with a smile.

"Happy."

"Aye sir!"

Happy flew inside the house, and a few seconds later, he flew out, carrying five bags with him.

Happy then began to distribute them, giving Erza, Gray, Lucy, Gajeel, and Wendy one bag each.

"Alright, I want you guys to explore the Island, on the south, there is a snowy mountain range, at the east there are countless of active and inactive volcano, on the west there is a misty swamp, and here where we are staying is the titanic forest. I want you to go wherever you want in these four places and bring me proofs that you hunted fifty s-class beasts, and before that, you won't be able to return here."

Lucy and Wendy looks scared, they couldn't help but tremble in fear, even Gray and Gajeel doubts if they can really do it, only Erza remained calm.

"These bags contains basic necessity for you guys to survive." Natsu said with a smile, "Now then, good luck, and stay alive?"

However, before they could even move, a magic circle appeared on the ground, and a beautiful young woman with short-pink hair wearing a maid outfit appeared.

"Virgo?!" Lucy exclaimed in surprise, and a bit annoyed that her spirits just keeps 'popping' out without her permission.

"Princess, there's an emergency." Virgo said, gaining the attention of the Fairy Tail members, "The Celestial Spirit Realm is in danger."

Everyone was shocked, with Natsu being the only one to remain calm as he just narrowed his eyes and stared at Virgo.

Then, he smiled and began to approached.

As Virgo was about to explain the 'danger' that the celestial spirit realm is facing, she suddenly noticed a man approaching her, for some reason, he looks kinda familiar.

It took her awhile before she managed to recognized him, "Natsu-....-sama?" The fourth smiled and stopped in front of her, then he raised his hand, and flicked her forehead,

"Aahn~!" She let out a pained, yet seemingly ėrȯtɨċ voice, the boys, mainly Laxus, Gray, and Gajeel, couldn't help but blush, Virgo's voice just caused them to have a wild imagination.

Natsu just smiled, he wasn't that affected by her voice, 'his' girls had teased him too much that he gained a strong resistant for something like this.

"Are you sure that this is not just a prank so that you can take us in the celestial spirit realm?" Natsu asked with a smile on his face.

Virgo was staring at Natsu with feverish eyes and a faint blush on her cheeks, though when she heard Natsu's question, her eyelid twitched.

Of course, this little action didn't went unnoticed by the fourth as he smiled, "As I thought, tell the Spirit King that we are busy this time, if he want something then perhaps we could go there next time."

Virgo seems to hesitates for moment before she nodded and made a 90° bow before excusing herself.

"Then, I'll excuse myself, farewell, Princess, Mast-...Natsu-sama." She then disappeared through the magic circle that appeared on her feet.

Natsu smiled and turned towards the Team A and smiled, "Alright, no need to worry about what she said, its just a prank. Now, you can go and start your training."

"This isn't training!! This is pure torture!! And how did you even know that what Virgo said is just a prank?!" Lucy exlaimed with tears threatening to fall from the corner of her eyes.

Natsu just smiled and instantly appeared in front of her, he brought his lips to her ears and whispered, "Don't worry, you won't die." Then, she carried her, raised her above his head before throwing her away.

"AAAAAAAAHH!!! DAAAMMNN YOUUU NATSUUUU!!!!"

Natsu made sure that if she couldn't save herself, then she will fall in water, that is deep enough that she wouldn't be able to touch the bottom.

"Alright who's next?" Natsu said, only to see that only the Fairy Tail B, Ultear, Meredy, and the exceeds(except Carla) remains.

"Oh? They're quite fast." Natsu laughed.

"So? Are we also going to do something similar to them?" Laxus asked, while folding his arms. "If so then it shouldn't be difficult for me to finish it within a month or two."

Natsu shook his head, "Laxus, Mira, for your training, how about hunting a Saint-class beasts?"

Their eyes immediately widened in shock, fighting an S-class beast is already difficult enough due to their hard bodies, but you actually wanted us to hunt down a saint-class beasts?

"Head towards the center of the island, there is a tall mountain there, on top of it, there are five saint-class beasts that rules this island." Then, Natsu took his saint cloak, "Bring this with you, those beasts should still remember my scent, as long as they smell that, they won't kill you, at most you'll be half-dead, but alive nonetheless."

Mira immediately grabbed his cloak, not caring about how the others look at her.

Natsu just shook his head and said, "Alright, don't waste your time here, go now, I'll take you two back once we are about to return."

"I think I'll also join with them." Lily said as he walked towards Mira and Laxus, he also planned to train as even Happy is now stronger than him.

"What about us, Natsu-sama?" Kagura asked, even though with her current level, this three months of training wouldn't actually increase her strength by much.

"Hmm~ well, I want you guys to observe them, and when their lives are in danger, save them, but don't reveal yourself."

"How can we do that?" Ariel asked. Even though she's fast, she was sure that she couldn't instantly appear and save one of them, unless she observed them 24/7.

"Hmm, he should be here soon."

"He?"

Then, a man wearing a rune knights uniform suddenly appeared beside him.

"Doranbolt?"

Natsu smiled patted his shoulder, "You see, Mest, or as you know him as Doranbolt, still owes me a favor, so I ask him to help you guys. With his ability to teleport, he can help you guys."

"Are you sure that its okay to leave a man in a house with only girls?" Ariel said with a smile, however, her smile caused Doranbolt to shiver in fear.

"He won't even go near you guys," Natsu said with a smile, before looking at Doranbolt, "He doesn't have the guts."

This is the first time that Doranbolt has been this afraid, even when he went to Alvarez, he wasn't as scared as he was now,

'After this is over, I will definitely leave, no need to ȧssociate myself with them.'
