First Order: Graduation, Scolding and Treatment

After dropping off Izuku home...

They had to use magic to adjust their clothes' sizes just so they don't have to buy clothes again! Expensive!

They stayed in Traverse Town to train in its districts.

'Alright everyone! You mastered how to fight as a Keyblader!' Naruko told the boys. 'Your final training before your debut is we'll clean up Traverse Town, and find its Keyhole to close this world away from the Heartless! We can come and go but they sure as hell can't!' she said. 'Onward to the Infested Districts!'

And so they went...to deal with nonstop Heartless swarming towards them.

'Dang, they're creepy...and they literally come out of nowhere!' Lavi gasped out as the boys fought off the Heartless while Naruko watched from afar, only moving to defend herself and that, was it.

And it took a whole day for the Second District to run out of Heartless.

'Good job guys!' Naruko smiled. 'Third District is next.'

'EHHHH?!'

'Our battles never stop until Heartless run out in an area. None of us have a choice but to clear them out to protect the people.' said Naruko. 'We clean up Traverse Town so we can find this world's Keyhole...and I'll have you guys take turns sealing worlds away as experience. We'll start with Lavi. He'll be the one to seal this world when we find the darn thing.'

'Right...'

Soooo yes. It was a rather harrowing experience not to mention the Exorcists learned the hard way why Naruko was so fast in clearing out Level 3s...due to Heartless Mob-Rush Mentality, you'd be forced to move as fast as possible lest you lose your heart to the creatures. They had to force their bodies to move real fast.

Then they went Keyhole Hunting...

...and it was so hidden they found it by ACCIDENT, and it was guarded by two huge Heartless monsters by the fountain in the First District.

'Have fun boys! This is your final exam before we officially start working~!' Naruko called out.

'Aren't you gonna help out?!' Allen wailed desperately.

'Hey, I cleaned up four worlds before I went Heir-Hunting!' came the all-too-cheerful reply.

'That means we deal with this shit ourselves.' Kanda forced a smile on himself. These guys are tougher than the giant idiots in Edo...they're just stupid magic metal with trapped souls inside. Heartless are more durable because 'mind makes it real'. Heartless can imagine themselves stronger based on the darkness of their hearts which was why it takes a strong heart to treat them like they can treat akuma back home. Even the weakest Heartless, the Shadow, needed a few whacks before they're dead while Naruko just needed 'a mere wave' of her Keyblade and they're dead.

And its not easy to have a strong heart, Naruko would tell them. One would need 'serious soul searching, determination and resolve' to have a strong heart.

'Have fun, she says...' Riku twitched. 'Easier said than done!' and they had great difficulty fighting the two giants who were kinda strong.

But their existence is jarring, in a way.

Well, what kind of people they used to be before becoming Heartless? Because apparently the bigger and stronger the more horrible they were in life as humans that it was a BLESSING to see mostly small ones as Naruko had a lot to say in the matter, with Lavi recording like crazy with his magic in his homemade book being a Bookman.

After defeating them, the Keyhole appeared.

'This is it Lavi!' Allen cried.

'Right-O!' Lavi twirled his large keyblade and fired a Sealing Beam at the keyhole with intent to seal it away, and it was a success.

'Its a successful sealing.' Naruko smiled. 'Now let's fully-clean up Traverse Town of the remaining trash and by then, you're official Keyblade Wielders. We can now travel and save other worlds!'

'Sooo we'll be doing this a lot?' Allen asked her.

'Exactly!' Naruko beamed. 'I wish you four could, but sadly, two more worlds to go before I have to take you back home, leaving only Sora, Riku and Myself to do the work.' she said. 'You guys can't be AWOL for long in your jobs after all.'

'Awww!' Lavi pouted.

'Well Lavi, that is the downside to belonging to an organization.' said Naruko wryly. 'Remember the secrecy, OK? Just lie that I trained you in some mountain or something.'

'Two more worlds to go after cleaning up this town...' Allen mused. After that, they'll be going home.

'Yup yup!'

'...I'll miss the food...' Allen whimpered mournfully. Kanda and Lavi sweatdropped. Naruko, Sora and Riku gave him incredulous looks. He cares more for food than his job!

Third District...

If Second District was bad as there's newcomers in no time flat, this was worse.

It was no wonder whoever lived in a barriered house, they really had to put a barrier for safety but who's dumb enough to live out here?

Welp, no time to ask that.

'Hmm! Good job in cleaning up your first world boys~!' Naruko smiled. 'Soon these districts can be inhabited by more refugees. Let's go talk to the Vigilantes.' and she led them to the barriered place!

The Exorcists thought, "They're the dumb ones wanting to live out here?!"

And so...

'Anyone home at this hour~?' Lavi called out as they went in.

'Oh, hello there!' a beautiful young woman in a pink dress greeted them. She has very long brown hair in a high pony-braid, long wavy bangs framing her face along with two shoulder-length ringlets. Lavi went 'strike-mode' for her looks. 'My name is Aerith. How can I help you?'

'We're here to talk to the Vigilantes about the expansion of Traverse Town's Refugee Residences.' said Naruko. 'We cleaned this world up of Heartless and closed its Keyhole so no Heartless will be here for a long time.'

That made Aerith lit up.

'Really?! That's good news!' she gasped out happily. 'Leon and the others are out though, so it'll take quite a while for them to get the news. But still...are all of you Keyblade Wielders?' she asked incredulously. 'So many...its rare to have so many at once!' she exclaimed in relief. 'In history...the most we'd get is three...in over ten years.'

'Well, our Master went for broke and sought out Keyblade-worthy hearts.' said Lavi. 'Our training lasted 9 months and three weeks...but that's only because most of us already had combat experience at the start. Who knows about true-blue rookies who aren't even physically fit.'

'They'd need two years of work for that.' Naruko snorted. 'Or three. But the hardest part is finding students with strong enough pure hearts of light that can be chosen by the Keyblade. By the way, out where?'

'King Mickey's Royal Magician and Royal Knight Captain were sent here months ago to look for a Keyblade Wielder...well, we had no idea you were training elsewhere...so they left looking for you since we gave them your name Naruko. Leon and the others are building a Gummi Ship as a precaution.'

'Hooo...if they're willing to sell that ship to us, how much?' Naruko asked her. 'My Glider's getting cramped.'

'Ahaha, I have to ask them that.' Aerith giggled. 'Let's go to our underground base.'

xxx

Underground Base...

It was both a Hangar and Factory, and a Command Center even.

'Leon! Everyone!' Aerith called out. 'We have plenty of Keyblade Wielders!'

'Y-you can't be serious Aerith, there's no such thing as 'plenty'!' Yuffie sputtered. 'Those guys are super-rare and Naruko's the only one we know so far!'

'Ohhh you bet there's plenty!' Naruko grinned, stepping out of the shadows. 'Hit it, boys!' the boys all flashed out their keyblades, causing Leon, Yuffie and Cid to gape at them in shock and disbelief.

'EHHHHHH?!'

'S-so many...' Leon gasped. 'In that case, restoration will be a fast one for sure!'

'I've been out training students Leon.' said Naruko. 'We cleaned up and sealed Traverse Town as their Final Exam so this world is completely secure. You won't be seeing Heartless here for a long time so Expansion is now possible.'

'We should hope so.' said Leon with a small smile. 'People are getting cramped now. Frustrations are mounting like you wouldn't believe.'

'Right. Sooo are you guys willing to sell that ship in exchange for about a thousand software parts and 50 large hardwares?'

'Oi oi, such stuff ain't easy to get!' Cid sputtered out.

'With my work ethic, I doubt that.' Naruko grinned. 'Space Heartless are doggone useful for 'farming'.' and she flooded the room with her wares.

'I'd say its a sold matter.' said Leon, scratching his head. 'With this its easy to build a new one in three months. Hang on a minute, we need to upgrade this current ship with some parts since we had to be real cheap with what we've got.'

'No kidding, me, an engineer, forced to be cheap on my work, a scandal!' Cid scowled. 'Its difficult to go out but this is ridiculous! These parts came right on time I say!' he said. 'You guys wait a bit before we can give you the current ship, alright?'

'Sure! I'm getting real cramped since someone suggested I break tradition and take in more people.' said Naruko. 'When standard by Masters is that three at a time.'

'There IS a good reason for that!' the monitor came to life, showing Yen Sid.

'Master!' Naruko answered as they faced the ancient wizard.

"This is Naruko's Master?" they all thought.

'Naruko you reckless child!' Yen Sid scolded. 'There's a reason we have three at a time!' he exclaimed. 'We literally give up a bit of ourselves to trigger the awakening of the next generation which only succeeds if they were accepted. So far I can see that Sora was chosen by the Keyblade without having to be your official heir while I heard straight from you Riku was Terra's so you didn't 'spend' your heart too much and young Izuku sought his dreams and gave up the opportunity to be a Keyblader, but taking in a fourth, is an absolute no-no! Think of your heart and your own welfare!' Naruko winced at being scolded. 'For now you're lucky, but, seriously!' he grunted, doing an armfold.

'I'm sorry Master, I thought its possible to go beyond three!' Naruko apologized.

'No means no child, no matter how strong we are at heart we can never give up too much of our hearts or it'll endanger us.' Yen Sid sighed. 'For us to have more Keyblade Wielders, our students must also become Masters of their own, and take in three students and the cycle continues. 'If you ever see a Fourth, I shall make that one my heir but you train that person given how I have my hands full but at least I have had three heirs of my own then, at least, officially...'

'Allen. Nea. Lavi. Kanda...you four are Naruko's official heirs.' said Yen Sid. 'Naruko has broken the standard rule that she must recover for half her life now as a result while she retains her strength, but her own heart is now considered 'injured'. However, one of you must have a body.' he said.

'You mean we'll be separated?' Allen asked him.

'Yes.' said Yen Sid. 'I need to speak to Kanda as well.' he said grimly. 'Naruko, bring your students here.'

'Yes sir.' and Yen Sid was gone. '...Master only ever had two official students. Me and King Mickey.' she explained to them. 'He never had a third.'

'Heee...'

'Welp, we go now.' said Naruko. 'Makes me wonder what he has for you three.'

Mysterious Tower...

'Wow...this place is a literal floating island isn't it?' Allen marveled as the grounds are covered in fruit trees, fruit shrubs and flowering shrubs.

'Welcome to my home of seven years.' said Naruko with a grin. 'Master likes things simple while I want my area classy and all...so only my room's modified. Haha...' she chuckled. 'Not far from this place is Twilight Town where we do our shopping.'

They went inside to climb up a long flight of stairs...

'This stairway is ridiculous.' said Kanda as they went up.

'Well, these stairs are connected to Master's Keyblade. Any Heartless dumb enough to step on the steps are instantly killed.'

'You mean this world isn't sealed?' Allen asked her.

'Nope. He lets them drop by so he can stay in shape. They're dangerous but thankfully stupid.'

Upon getting to the top...

'OK, WHERE is your room in this place?!' Lavi sputtered. 'Half the tower is just stairs!'

'Ah, the living quarters are dimensionally behind his office, the most fortified place in this tower.' said Naruko. 'We live here with the three fairy godmothers.' and she knocked before entering. 'Master, we're home!'

'Welcome back, Naruko.' said Yen Sid. 'I have things ready here already. But I can only inform Nea and Kanda of it. Everyone else, wait in the living room.'

xxx

Living Room...

Lavi, Sora and Riku are stuck in the living room while Naruko got tea and snacks ready.

'Wonder why they're called out for?' Sora wondered aloud as Naruko put a teapot, four teacups, forks and bread plates and a large Mushroom Pudding on the table. Choco-Banana flavor!

'Beats us.' said Lavi as they used a knife to cut up pieces for themselves while the teapot magically moved to pour tea for them. 'All we can do is wait, yeah?'

xxx

Yen Sid's laboratory...

Nea and Kanda can only stare at the man.

'...so that's what it's going to be.' said Yen Sid.

'Maintenance for me while Nea gets a new body.' said Kanda. 'So you gonna get it?' he asked Nea.

'...on the condition he can erase the Noah Gene within me so I will be the only and last 14th Noah.' said Nea. 'If I move in, I will take all the genes from Allen's genetics and you must destroy our Noah Genes.' he told Yen Sid seriously. 'This will be our last war. With the Keyblade, perhaps we can destroy the genes within all humanity in our world, preventing reincarnation ever again.' he said, taking out his Keyblade.

'That's a rather frightening-looking keyblade, Nea.' said Yen Sid as he can discern what the man was and the man knew it.

'Well...the Noah Clan are darkness themselves and it doesn't help we possess Dark Matter. We're not human anymore.' Nea chuckled bitterly. 'Your offer is a miracle in itself, Master Yen Sid.' he said.

'Mm. It'll take quite a while for the split to be performed.' said Yen Sid. 'You and Kanda will be inside those...for about a month.' he said, looking at two tanks. 'With the power of the stars, I can read everything but even they keep a few things away for good reason. Naruko too, can read the stars. She will be a good guide to all of you. But I ask of you in return to ahem, stop her when she goes overboard.' he sighed tiredly. 'She is dedicated and dutiful but she goes overboard. Because she feels...its what Terra would do.' he said.

'When one is deeply hurt, but given salvation by someone...that someone becomes their reason to live. That's what happened between my twin brother and my nephew.' said Nea. 'To the point of even following their path when things could have been different.'

'That couldn't be any more truer in this case.' said Yen Sid. 'Naruko longs for a family. She has a grandfather in me, and adopted a brother figure in her life...but she longs for parents who would care about her and put family first. Her mindset about that is...complicatedly complex.'

Due to their stay, Lavi and Naruko trained Sora and Riku in battle while waiting for Allen and Kanda to come back from treatment...by traveling and cleaning up worlds and sealing their keyholes. After Lavi had his turn with the sealing, Sora was next, and then Riku before going home.

Lavi was having the most fun due to having to document their journey. Maybe he can make a career out of this and be the first-ever Interstellar Bookman!

After a month, Kanda and Allen are back out. With a plus-one. Neah has his own body now but he couldn't have his old form back due to 'lacking genetic material' thus his body is basically a clone of Allen's body. His fashion sense, however...

'Ohya ohya, look who's out now.' Naruko commented as Nea is out. The only way to tell him apart was his wavy hair and his aristocratic fashion sense while Allen happily adopted the bad boy look as he found it really cool.

'Yeah, its nice to have my body again.' said Nea. 'Because we'll definitely go crazy back home.'

'Well, we have two more worlds to go before I send you guys home.' said Naruko.

'Two more worlds and after that, can we have our final days in Food Paradise, pretty please?' Allen begged. 'It'll be a while before we can go back there again!'

'Ahahaha! Hai hai!' Naruko giggled, 'Besides, I have one thing in mind for you guys anyway.'

'One thing in mind?' Nea blinked.

'Yes. Sooo let's clean up two more worlds, OK?'

xxx

Food Paradise...

LIFE...

The gang found themselves in Onsen Sharks.

'OK guys!' Naruko piped. 'Time for a health treatment!'

'And how?' Sora asked her.

'See those slender fishes down there?' Naruko said as they saw all the skinny fish down below. 'They are called Doctor Fish. And there are many types. Diet Fish, Tumor Fish, Blood Tetra, Cancer Sucker, Skin Garra, and Melanin Gourami. They eat diseased cells and blood all over our body by inserting their very thin sucker tongues through our skin. Its painless, don't worry!' she chirped. 'After this we'll go to a pool full of Melanin Gourami and Skin Garra so we'll have beautiful baby-soft skin!'

'Too bad for Izuku he didn't get to go here.' said Allen.

'He did, late at night.' said Naruko. 'On his last day here. He never dreamed he'd have a skin to die for either! Hahaha! Well, Heroes should also look good, right? And we're heroes, so we should also look good.'

'You mean unknown heroes.' said Riku wryly. 'We can't let what we are be known.'

'Still heroes.' Sora grinned.

It was thus, a weird experience that fish were healthy spa treatments.

They came out 'white as an aristocrat' as Nea put it with no skin callouses whatsoever.

However, treatment is heinously expensive.

The amount of money Naruko unloaded, was unholy.

'THE HELL DID YOU GET ALL THAT MONEY FROM?!' they all cried, eyes popping out.

'Where...we sold some stuff, right?' Naruko pointed out. 'We obtained high-class food stuff, sold some of them, its only natural to have pocket money.'

'P-pocket money...that?' Sora felt faint...faint he did, Riku had to catch him.

"He just HAD to faint first..." Riku was just about to faint too but now he had to stay awake...

'With that kinda money I could buy a large land and build a large mansion with it!' Nea howled in horror. 'And we paid that much for skin treatment?!'

'Well duh? Didn't you see the pricing board?' the boys sharply turned to look at the price board.

Diet Fish = 1,250,000 yen per fish

Melanin Gourami = 500,000 yen per fish

Skin Garra = 200,000 yen per fish

Blood Tetra = 20,000,000 yen per fish

Tumor Fish = 100,000,000 yen per fish

'H-haaa...' Allen was horrified. 'And lots of fish swarmed us all over...its probably billions!'

They were in severe shock.
