Seven Years Passed

Team Natsu 'Returns'

The next day of training continued swiftly, everyone was paired with a suitable partner to help increase their magic and right now Natsu and Erza were teaching Lucy how to re-equip in case her keys were ever thrown away from her. "The pocket dimension doesn't have to large since it'll only occasionally carry your keys, but with the small size it'll be a faster re-equip." Natsu explained as he held Levy's keys for a demonstration.
"So how should I move my hands then to un-equip my keys?" Lucy asked as she tried to imitate how Natsu and Erza pose when they equip their armour.
"Since you're only grabbing your keys you'll thrust your hand out like this, imagine yourself grabbing your keys and pull back." Natsu demonstrated by un-equipping the keys then re-equipping them to demonstrate.
"First we need to activate your pocket dimension though. Natsu, since you have more magic would you do the honours?" Erza asked as Natsu nodded and put his hand out.
"Tibi enim sinum dimensionem, lego ut tibi in futurum subviniat." Natsu chanted in an ancient language as Lucy could feel a warmth, it was far away but at the same time it felt close.
"Woah, is this how it feels for you guys?" Lucy asked as Natsu and Erza nodded.
"It can get overbearing sometimes but since you cant dismiss it, it gradually increases your Etharno levels." Erza smiled.
"It's why I couldn't ever get ahead of Erza back seven years ago, it's cheating on her part." Natsu smirked as Erza elbowed the Dragon Slayer.
"I got here with my own-" Before Erza could say anything else a bright flash happened in the natural circle the three mages had formed as Virgo appeared and bowed.
"Hey Virgo, it's been years hasn't it?" Natsu grinned as Virgo nodded.
"Mhm, I wish we could be meeting in a better circumstance Natsu but right now the Celestial spirit world is in trouble." Virgo said as Natsu sighed.
"I told you guys not to try and pull this. If you want to celebrate Lucy and the rest of Team Tenrou's return then you guys have to come here." Natsu sighed.
"Natsu, how could you just brush Virgo off like that? What if it's serious!" Lucy asked in shock.
"Because they told me their plan five years ago when I accidentally went to the Spirit Realm." Natsu groaned.
"You're no fun Natsu...fine we want to celebrate with you princess." Virgo admitted.
"And why is Natsu so adamant we shouldn't go to the Celestial Spirit world?" Erza asked.
"Time moves differently in the Celestial Spirit world. One day in there is three months in our world. I was in the Celestial Spirit realm for an hour on my end but was gone a week in Earthland time." Natsu sighed.
"We promise to make it a quick party Natsu." Virgo promised.
"Fine...everyone gather round, we're going on vacation." Natsu sighed as Horologium appeared and gave everyone some clothes so they could survive the spirit realm.

As the beach training group, Minus Levy, Jet and Droy who wanted to spend the week training, got to the Spirit world the King stood triumphantly with a grin on his face. "Welcome back Lucy and friends, let's party!" The King roared as all the Celestial spirits, minus two of the S-Class spirits who were in use back in Earthland, all arrived including the hundreds of silver keys.
"Lucy, welcome back beautiful." Loke flirted as Lucy rolled her eyes.
"Natsu, it's been too long since you last visited." Scorpio smiled as he and Natsu fist bumped.
"We will only be here for an hour; we need to get back to training for the games." Natsu responded smiling.
"Oh come on Natsu, stay a while!" The Celestial Spirit King grinned.
"Sorry, you know why I'm so worried though right?" Natsu asked as the king nodded.
"Do they know yet?" The King asked as Erza approached Natsu.
"What are you talking about Natsu?" The Re-Equip mage asked.
"We will discuss this back on the beach, for now focus on celebrating." Natsu brushed to the side as Erza glared at Natsu.
"Tell me now Natsu..." Erza growled.
"I said, back at the beach. I can't explain it too good myself, so we'll need the help of my help in this matter." Natsu glared back as Erza nodded, leaving Gray shocked.
"Natsu...you stood up to Erza?" Gray asked in shock.
"Yeah, I won't cave in when its not my story to tell." Natsu shook his head.
"Well then, a warning for you Natsu...the time will come when the keys are needed...then you wont be able to escape them no matter if you use your keys or not." The king warned as Natsu nodded.
"Thanks old man." Natsu smirked as the group moved on and started celebrating.
