Chapter 1

It was the day Harry and his two best friends were in Diagon Alley, getting books, quills, and any important items for a fresh new year at Hogwarts. They were going back for their sixth year, hoping it would be just as fun as the rest.

"C'mon now," Ron urged as they pushed their way through the crowded streets to go find Ron's family. The three had separated from Mrs. Weasley and Ginny while the twins, Fred and George went their separate ways. Harry assumed they were trying to sale some more of their joke tricks. They were now out of Hogwarts and planned to start a joke shop with the prize money Harry had given him in fourth year.

"There they are," Hermione, the only girl out of the three, said aloud. Ron and Harry saw her point to a plump redhead woman with a girl just one year younger than the three. They were going into "Magic Brooms" to get Ginny, Ron's younger sister, a new broom. Her broom had broken by accident during the holidays from one of Fred and George's tricks. It was in fact embarrassing to Ginny since Harry had been at the Weasley's house.

Harry, Ron, and Hermione began to push their way again into the crowd to reach the store, which was located on the other side of the road. "I never thought it could be so crowded!" Ron complained while he had a hard time trying to pass by a group of people.

"It reminds me of a mall when people find out there's clearance sales!" Hermione said, making Ron look at her confused.

"What?" he asked while Harry knew exactly what Hermione was implying to. It was clear that Ron was not use to Muggle customs since his family lived off of magic.

Letting out a frustrated sound, Hermione answered a quick, "never mind," when the three managed to pass the crowd. They entered the store after Mrs. Weasley and Ginny.

Unknown to the three, a figure just around the corner inside an alleyway was watching them closely. A cat was with the person, watching carefully too. The shadow of the dark alley hid their faces as they kept their eyes on the three until they disappeared into the broom shop.

"Shall we go?" the cat asked, looking up at its owner.

The figure nodded saying, "I think it's about time we make an appearance anyway."

The two walked out into the light as they began to head towards the broom shop where the three teenagers had gone in. The figure appeared to be a girl at the age of 16, with long gold shiny hair that was held up high in a ponytail by a big red ribbon. She was wearing jean shorts and white sleeveless turtleneck shirt. Her cat was white with a crescent moon engraved in his forehead. They entered "Magic Brooms."

Harry and Ron were busy looking through a long glass case, the new very expensive broom inside it. Hermione and Ginny were with Mrs. Weasley, who chatted about safe brooms with the shop owner at the counter. The two girls talked about a book they read over the summer.

"Wow, look at it! This is said to be way better than any other broom made!" Ron commented as he bent down and pressed his face against the glass.

Harry admired the broom, wondering how it would feel to use it in a game of Quidditch. It made him smile when he pictured the look on Draco Malfoy's, his rival since first year, face when he saw him with this magnificent broomstick. "Yea, the Nimbus 3000 looks cool huh," he let out. It made his happiness die when he knew very well that he couldn't buy it and that the expression on Malfoy's face wound never show in real life.

The door of the shop opened and a blonde girl came in, a cat behind her heels. Harry watched her as she came in. Ron, who also heard the door open, looked up to see the blonde and her cat. The two boys were in a corner of the shop as they watched the girl's cornflower blue eyes look around for someone. And when her eyes met Harry's he felt his heart skip a beat.

"Harry, am I dreaming or is there a beautiful girl coming our way!?!" Ron tried to whisper as the girl and the cat began to walk towards them.

Harry remained silent as he watched her odd moves. He thought maybe she had seen him on the streets of Diagon Alley and wanted to find out if he was Harry Potter. *I really hope she's not another one of those annoying people who ask if I'm the-boy-who-lived.* But she didn't seem the type. She didn't have that exciting look in her eyes that many held when they found out they were going to talk to the famous Harry Potter. She just walked towards them casually. But it made the two boys puzzled when they saw her whispering something to her cat.

Finally, she reached them. "Hello there," she greeted, giving Harry and Ron her winning smile.

"Uh...h- hi.," Ron stammered. He went to shake her hands. "Ron Weasley."

She smiled warmly at him, giving him full attention. Harry immediately knew she wasn't an annoying fan. At least he thought she wasn't. If she was, she would have asked already if he was Harry Potter practically jumping down his throat, not minding Ron at all.

"Aino Minako. And this is my cat, Artemis," the blonde brought up as Ron and Harry looked down to notice the white cat.

"Blimmy! He has a crescent moon on his forehead!" Ron noticed, making Harry confused.

The blonde laugh nervously. "Uh-we... I mean I-I found a charm-where you could engrave symbols on creatures. I just thought this suited him."

"Don't get me wrong, it does! It's just that I never seen it done before," Ron quickly responded. But what the blonde said only made Harry's mind rush with questions. "You're a witch then!" He let out.

Minako turned to him, now giving him full attention. She smiled at him. "You must Harry Potter," she said, making Harry's heartbeat quicken. *Oh no! Maybe she IS a fan!*

"Uh-yes, I am." Harry answered back, waiting for her to go crazy and maybe even ask for his autograph. But she didn't. She just kept her cool, making him feel relieved.

"Well nice to meet you Harry. And of course I'm a witch," Minako laughed. "After all, a normal teenager can't walk around Diagon Alley."

Soon enough, they were interrupted by Hermione and Ginny. "Harry, Ron," Hermione called before she noticed Minako. "Oh hi there," she greeted with a pleasant smile. Mrs. Weasley had gone in the back storage room with the owner of the shop to find the broom.

"Ah yes, Minako, this is Hermione and my little sister, Ginny. Hermione, Ginny, this is Aino Minako." Ron introduced. But he had forgotten Artemis who was sitting near Minako's feet. He let out a "meow" for protest to remind them that he was still down there.

*I may be a cat but it doesn't mean you can treat me like I'm a rug!*

Hermione heard him right away and looked down. "Aww, how cute! He's simply adorable!" she said, going down on one knee to pet him. Gunny went to join her, petting Artemis. But Hermione quickly noticed his crescent moon. "Hey, what's this?" she asked while examining the mark.

"Oh, I- er... used a charm to make it appear." Minako lied again.

"Neat huh," Ron said while Hermione and Ginny nodded.

When the two girls were back up on their feet, Artemis now in Ginny's arms, Hermione said, "I've never seen a charm that can do that in book before. Maybe you can show me some time."

Minako again laughed nervously, "Uh-yeah, of course!"

"Minako," Harry spoke again. "What school do you go to?" This had been bugging him since he found out she was a witch. It was obvious she didn't go to Hogwarts. During his five years there, he had never seen her in the corridors or in the Great Hall. There was just something about her that made her feel... mysterious to him.

"Well, I can't tell you what school I USED to go to," Minako began. She knew very well that she had never gone to any witchcraft and wizardry school at all. "But I AM transferring to Hogwarts this year," she finished, making the four's face light up."

"So you'll be in the same school with us!" Ginny said.

Minako nodded. "Yup, I'll be spending my sixth year in Hogwarts.

"Wicked! You'll be the same age as us too!" Ron spoke, making Minako nod again. Ginny was the only one who wasn't going to be in sixth year. She had fifth year, the horrible year of so many exams.

"It'll be great if you're in the same house as us. We're all in Gryffindor," Hermione explained.

Minako couldn't help but smile broadly. She didn't expect that she would make friends so quickly. And what made her happier was that her mission was standing right in front of her. Harry Potter. *This doesn't seem as hard as Artemis said it would.*

Harry smiled back at her. He didn't know why he was feeling something odd coming from this girl but he quickly ignored it. She seemed very pleasant and was very attractive. It would be great if she joined the trio.

But just then, again the door of "Magic Brooms" opened to let in a tall blonde pale boy. Two even bigger and very chubby boys were right behind. Minako, her back towards the door, noticed the cheerful looks on the four faces of her new friends change to grim glares.

"Malfoy," Harry grumbled under his breath as Minako turned around to see the pale boy and his two cronies walking towards them. She noticed the blonde held a scornful smirk on his face while his icy light blue eyes bore a whole into Harry. The moment the three reached the five, the tall blonde boy pushed Minako to the side so he could have a much better look at Harry and his friends.

"Well you look at this Goyle, Crabbe. Scar-head, the two weasels, and the mudblood are in our way from the Nimbus 3000." He scorned, smirking to see their angered faces.

Minako, who was not pleased at all for being pushed out of the way, cleared her throat. "It's not polite to push," she pointed out when everyone looked at her.

Malfoy only sneered at her before turning back to the others. "Well get out the way weasel!" he said before he pushed Ginny, making her fall over with Artemis.

"That was uncalled for Malfoy!" Harry yelled angrily as Ron and Hermione went to help Ginny up. When Ginny was on her feet again, Ron stood protectively over her near Harry, his hand balled into a fist and ready to strike.

Malfoy only grinned evilly. He loved it when he could see flames in Harry and Ron's eyes. It made it much more exciting if there was a fight. But instead of him getting a punch from Harry or Ron, he got a hard side kick right in the chest by Minako. "That was MY cat you just pushed over," Minako said very angry.

Minako didn't kick Malfoy just because of Artemis. That he had pushed Ginny, making her almost land on top of her white guardian cat. She did it because she knew he was filth, calling Harry and the others mean names. She didn't know what mudblood meant though but kept it to herself.

Harry, Ron, Ginny, Hermione, Goyle, and Crabbe looked shocked as Malfoy let out a growl when Minako's feet made contact with its target. He quickly fell to his knees as he hunched over, trying to outdo the pain on his chest. But quickly everyone, minus Crabbe and Goyle, burst out with amusement.

"WAY THE GO!" Ron cheered.

Minako frowned at Malfoy as he glared up at her, his face red. She next walked towards Ginny to take Artemis in her hands.

"You'll seriously regret what you just did!" he spat angrily as he managed to get back on his feet. They could tell by his expression that he was still in pain. Minako made sure of it since she aimed for his heart. But she hadn't kicked him hard enough to kill him. That was one thing she didn't want to happen.

"That'll be the day," Minako scoffed as the three bullies scattered away from them and out of "Magic Brooms."

When they were out of sight, Minako was praised by her new friends. "That was awesome!" Ginny yelled, a huge smile on her freckled face.

"Did you see that look on his face?! Priceless!" Hermione laughed.

Ron was chuckling the most, "I can see it now! First he was the bouncing- ferret, now he's the hunching-dragon!

Harry was extremely glade just like the rest of them. Now more than ever he wanted to be close friends with this girl, even if he still felt awkward around her. Minako beamed at her triumph. But she felt Artemis in her arms squirming, giving a sign that it was time to go.

"I'll have to go now. I'll see you guys tomorrow at the train station to Hogwarts," she said before giving them a wave and ran out of the store, leaving them confused with her rush.

A half an hour later after Minako had left Diagon Alley and was now in her apartment in London, she plopped down on the couch. "What a day," she sighed. Artemis went and sat on her lap. "Artemis, what's a mudblood?"

Artemis lifted his head that had been lying comfortably on his paws, to look up at Minako. "It's a term used for people who have muggle-parents. It's actually a very cruel name, like a curse word." Her talking cat answered.

"I see," Minako said. She waited for ten minutes before speaking again. "Do you think this is such a great idea? For me to be here when I should very well be in Tokyo guarding Usagi and Mamoru? Something could go wrong, and I AM the leader."

"Calm down. The others and the Outers are enough to watch over the two. After all, the reason you're here is because you're the leader. Dumbledore had asked to watch over Harry from Voldemort. You can't back down now, now that we're here. Besides, it's not a very nice way to treat an old friend."

Minako took in what Artemis had said. He was right. She couldn't back down now. She had gone too far, being away from the other Senshis the whole summer to spice'n up on her magic. After all, Dumbledore had been a good friend in her family for generations. He had been the headmaster when her father and mother had gone to Hogwarts. And he helped out the family many times during the years. This was a way to repay him she figured. For all that he had done. With her powers from the planet Venus, Dumbledore was sure she could protect Harry if Voldemort tried anything to harm him. This Harry Potter was very famous and seemed very valuable, and Minako decided to imagine him like an equal to the royal family. Her duty was to protect the queen and king. Now, her duty was to protect the-boy-who-lived. From Voldemort, who Dumbledore claimed has come back again.
