Harry Potter and the Kingstone's Power

Okay…I got a pair of reviews so far…and I guess this fic's reception is warm enough…enough to make a second chapter. This time the action kicks in as Kotaro Minami gets to meet the young Harry Potter while touring the Wizarding World…and encounters a few bad guys…and that's where the two heroes begin their encounter…in controversial results.

Lastly, I seem to overlook a small error regarding Chamber of Secrets, in which Harry and Ron were unable to get though Platform 9 ¾ due to Dobby's magic, and I apologize for that. So I'll be making some adjustment to accommodate the plot.

London, England, Harry Potter and Ron Weasley are riding on Arthur WEasley's car embedded with magic as for some reason they couldn't get through the barrier that connects King's Cross and Platform 9 ¾, so they had to sneak out Arthur Weasley's car and used magic to levitate it, and some witnessed it but chose to ignore it. The trip took them almost four hours and by the time they arrived, they were late for the opening feast, which Severus Snape, Hogwart's resident Potion master and head of the Slytherin House suggested that Harry be expelled for exposing their world which Albus Dumbledore, the head of Hogwart's School For Witchcraft and Wizardry, denied the petition, and opted to punish the two teens by cleaning toilets.

After serving their penalty, they were heading back towards their quarters when they chanced upon some house elves talking, and while eavesdropping, the two are now filled with worry about what they just heard from the talkative house elves.

"Have you heard…a Muggle came into our world by accident…yet he possesses a power which seemingly matched that of this world…he even fought a few Dementors and a hired Centaur…all by himself…"

"Yet he isn't a wizard nor a Pureblood…but where did he get that kind of power…I think Muggles are getting more dangerous at each passing time…perhaps the Ministry of Magic are getting frenzied at this time…"

"Well…this isn't our problem…we just heard the news…"

"And a Muggle-born Ministry member is using his connections to petition for that Muggle to have his memory retained…yet I wonder what will they do with that Muggle's power…"

"Well…let's continue our work…"

"Right…"

Harry and Ron glanced at each other as they wonder how to make out of this situation, as the "Boy Who Lived" recalled meeting Kotaro Minami for the first time and how the Japanese-born Muggle risked his life to save him and fought some Dementors and a "hired gun"…just as the Ministry members arrived and witnessed something they never seen before, and the two Griffindor members looked back at the events since 24 hours ago, as the memory of that fateful meeting played back in their minds.

48 hours ago…

Day 1…

At the Wizarding World, Kotaro Minami slept during the day while inside the train as the train makes its way through the train capital of the Wizarding World, unaware that he stepped into a different territory yet he had no idea what he got himself into, and since he is still asleep, he didn't notice the sceneries outside his seat's windows, as some Wizarding World residents are seen flying in their brooms.

As the hours passed by, the train conductor politely woke up Kotaro, informing him that the end of the station is getting near, and the Japanese-born adult prepared to get his things, as within several minutes the train comes to a stop and is getting ready to disembark from the train, though he was quite surprised to see what lies ahead of him at seeing the scenery in front of him.

"Eh??? I thought Britain is quite advanced than Japan…this looked almost like the 1940's in terms of modern scenery…maybe I boarded the wrong train…perhaps I should find the customer service and ask for directions…at least it'll help…"

As Kotaro looked around the train slowly left, leaving the "foreigner" on his own, and now he has to look around to help him navigate in this strange world. As he went to find someone to help him, the citizens there merely ignored him, thinking that Kotaro is also a citizen just trying to extort money from them and the hapless traveler had to find somewhere else to get some assistance. The walk lasted for almost an hour until a kind-hearted inn-keeper took him under his wing and slowly learned that a Muggle arrived here by accident, and knew that he must be turned over to the Ministry, but opted to let him enjoy the tour here before being picked up, and told him that he is in the Wizarding World.

"Really? This world is a parallel version of my world?"

"Yes…I'm surprised that you didn't freaked out…perhaps I can let you stay in my inn for today free of charge…in exchange…will you help me with the logs…? I need some firewood and I couldn't make them all by myself at least…"

"I'll do it. It's the least I can repay you…"

And so Kotaro settled in, he immediately began helping the innkeeper in making some firewood to have the fireplace work up, and within 10 minutes a lot were produced. As a reward, the kind innkeeper gives Kotaro free food and drinks, as this was the first time he has let a Muggle in his inn, and he was glad to met someone as kind as Kotaro.

Meanwhile, at the Burrows, the Weasley Family are gearing up for their trip towards Diagon Alley, which is tomorrow where they'll be getting supplies for their second year at Hogwarts, with Ginny making her first trip as she is slated to take her first year. As the day went on, Harry spend time with the Weasley siblings as Fred and George introduced their prank items as Ron and Ginny looked on. As bedtime is up, everyone settled on their beds with Harry sharing with Ron.

Day 2…

As the sun rises, Kotaro got up early and realized that his free stay is almost up, and to thank the innkeeper for his generous hospitality, he help make more firewood until the stock has tripled in amount, and the generous innkeeper gave Kotaro one last free meal before he gave him instructions on where to go so he can get some assistance. After some 30 minutes, Kotaro bid goodbye and left, while the innkeeper waved goodbye, a bit saddened that he'll never see another person like that again.

"Poor lad…once his memory's been rearranged, he'll never get to live up the experience he had…and though the Ministry will grill me…I have no regrets…it's an honor to play host to a stranger who repaid me with kindness…"

-

At the Burrows, all of the WEasley siblings and Harry are up and took their breakfast and afterwards Molly Weasley gave each of then floo powders and instructed them on how to get to Diagon Alley. Harry was the first to try and he got to Diagon Alley, his eyeglasses damaged but someone came and repaired it. It was Hermione Granger.

"My, my…you can't function without them…here…Reparo."

With a wave of her wand, Harry's glasses are repaired, and within minutes the Weasley siblings arrived, all are heading to Diagon Alley along with Arthur Weasley. As they all made their way in, they are greeted by Draco Malfoy, who, as usual, takes verbal jabs at Harry, and a fight might have taken place had it not for the arrival of Lucious Malfoy, Draco's father, and "reprimanded" his son for "making fun" at the Wizarding World's hero.

"Draco…that's no way to treat a hero…my apologies…I'll see to it that he'll be disciplined…"

"I appreciate it, sir…"

"So…you are Harry Potter…an honor to meet you…"

Harry saw Arthur Weasley giving Lucious a wary look, and he realized that Lucious is not what he appeared to be yet he maintains a neutral gesture, but then the tension seem to have ebbed at the appearance of Gilderoy Lockheart, who is famed for his books and other credits he showed.

Meanwhile, some kind-hearted Wizarding World citizens saw Kotaro as an innocent Muggle with a good heart, and politely guided him the way back to the real world, and within a few minutes he finds himself within a shopping center in London, near a playground that is just a few blocks away from Diagon Alley. As he was about to take out his itinerary to begin his tour, something unexpected took place.

A squad of Death Eaters, about 20 of them, appeared and began to recklessly used the Avada Kedavra charm at horrified bystanders, killing them on the spot while others unleashed their allies, such as rogue centaurs, whom the Death Eaters approached and used flattery to get their services with the promise to give them power, to attack other civilians. Then a rogue Giant was also unleashed, also being promised of greater power began to pick up children and began to consume them. Kotaro was quite horrified at the scene, and seeing the Death Eaters reminded him of fighting the High Priests of Gorgom.

"This is just like two years ago…now I'll have to do it again…"

- - -

The screams has also reached Diagon Alley and Arthur had to get his charges out of harm's way but Harry was being pushed out of the shop by panicking patrons, unable to get himself through towards the Weasleys, though Licious and Draco Malfoy were able to safely got away from the panicking scene. As chaos ensued, Arthur had to make sure his children get to a safe distance, and once they are, he used his wand to create a signal flare to alert the Ministry and the Order so reinforcements would arrive. After doing so he squeezed his way through the frenzied crowd just to get through Harry.

The panicking crowd were sure as a pain as they ran towards the rogue centaurs, not caring what would happen to them just they could get away from the attack, yet they went straight to them and got impaled in the process. Stampeding is also evident as many were trampled to death and Harry managed to get himself out of harm's way, but then saw the rogue giant stomping at the hapless victims to death, which leaves only him and a crying little girl alone, and one of the centaurs looked ready to stomp her with his hoof, but then Kotaro Minami came and grabbed the girl and gave her to the Griffindor student.

"Take her to safety! Go! I'll hold them off!"

Harry was taken aback by what he saw, and he can tell that Kotaro is an ordinary Muggle and now the situation is getting worse having an ordinary Muggle witnessing a magical attack, but to his surprise, Kotaro began to single-handedly too the fight to the single centaur, and managed to cripple two of the centaur's hooves by steping on them HARD, almost rendering him physically useless. Since the other rogue centaurs have no use for an injured comrade, they stabbed him with a long blade to death, and then they are motioning towards Harry and the frightened girl, which made Kotaro more worried.

"Leave the children alone!"

"Silence, you lowly Muggle! If you wish to die, then come to us!"

By then Arthur Weasley arrived and went to harry's side, and was also worried to see another innocent person challenging the centaurs, shocked to hear from Harry that it was an ordinary Muggle. But then the next scene would change their opinions.

"Henshin!"

Kotaro jumped up in the air and his body glowed in black and within moments he is encased in black armor and a red light emanated from his metallic belt, and for the first time in two years, he has become Kamen Rider BLACK. The centaurs and the Death Eaters were taken aback, seeing a Muggle in an armor resembling a grasshopper, and they can sense a source of energy from him, though they can faintly sense some magical aura within.

"Kamen Rider…BLACK!"

"Be not be intimidated! He's just a lowly Muggle! Kill him!"

The strongest of the rogue centaurs was the first to tryout his opponent and a fight broke out, which a few Ministry members arrived to assist Harry and Arthur, but were astounded to see BLACK facing a centaur. The centaur tried to impale BLACK with a spear but the Kamen Rider moved quick to avoid them and jumped up and landed behind his opponent and began did a strong cop on his nape, slowly knocking him out. The rest of the rogue centaurs were surprised at what they saw and are in a state of disbelief.

"Our strongest member of our race soundly beaten by a lowly Muggle???"

But the Death Eaters urged the centaurs not to be intimidated and decided to join the fight and used their wands to use a telekinetic charm to hold BLACK in place as the centaurs rushes in and began pounding him with their hooves. Despite his armored form, BLACK can still feel pain ad had to do something but with the wands holding him down he needed a boost to break free and knew of one thing to set him free.

"King Stone Flash!"

Black's Belt shone bright as the Kingstone emitted strong energy which caused the centaurs and the Death Eaters to back away as they became blinded by the light of the Kingstone and enabled him to mount a comeback, punching a centaur strong and sends him colliding with the other centaurs, but then the rogue giant came and tried to stomp his small opponent, but seeing the size of his massive target, he weighed his option and looked for a way to defeat him.

He managed to climb behind the giant's pants and climbed up, stealthily climbing through the back of the titan's clothing while the giant foolishly looked around for his small prey until BLACK reached the head, and willed the Kingstone's power to reach full charge, and its energy coursed through his right fist.

"Rider Punch!"

A strong punch it the giant on the top of his head, causing the giant to kneel down on both legs, feeling dizzy and was somewhat disoriented, and BLACK jumped down to get a distance while again willed the power of the Kingstone towards his body and then ran towards the prone titan, his right leg glowing.

"Rider Kick!"

A flying kick went towards the same spot where the giant was hit, and a strong kick did its job, and within more than a minute the giant fell down, and is dead. As BLACK glanced at the Death Eaters and the Centaurs, the opposing forces are considering trying another tactic when the rest of the ministry members arrived and the opposing forces were forced to retreat as they cannot afford to be captured.

Harry and Arthur approached the stranger and began asking him a few questions, which they confirmed that BLACK is a Muggle indeed, and when the ministry members surrounded the armored stranger Arthur lobbied the rest to lower their wands telling them that he is an ally who held off the Death Eaters long enough for the others to arrive. By then Kotaro reverted back to normal and Arthur managed to persuade the other Ministry members to let him take charge of Kotaro knowing that they'll just use their memory Charms at him to make him forget what he saw, and would give the Death Eaters opportunities to get back at him.

- - - END FLASHBACK - - -

As Ron and Harry went to Dumbledore's office, Harry then went to the headmaster and asked him about Kotaro's fate, worried that he might lose his memories and sent back to Japan and feared that he maybe targeted by the Death Eaters for chasing them away, but then Dumbledore assured to his charge that Kotaro is in safe hands and that Arthur Weasley "pulled some strings" so no unnecessary magical treatment come towards the wayward Muggle.

- - -

Meanwhile, at the HQ of the Ministry Of Magic, Kotaro was sitting on his rented room, awaiting for the next day as he will be examined by the Wizengamot for "unexplained" abilities he possessed. Outside, Percy Weasley stands guard wearing an invisibility cloak, protecting him in case some corrupt Ministry members might use magic on him to force Kotaro to incriminate himself.

To Be Continued…

Kamen Rider BLACK debuts on the Wizarding World, and attracted new enemies which would no doubt go after him for humiliating them. And harry Potter gets to meet him and now he is worried about the stranger's ultimate fate.
