A/N: Again, due to a little annoying thing called Writer's Block for my Kingdom Hearts fics, I'm creating another D.N. Angel fan fiction. It is a crossover fic with Harry Potter and Cardcaptor Sakura. It was my little sister who helped me get the idea for this when she and I were glancing at the fifth Harry Potter, D.N. Angel manga and watching Cardcaptor Sakura the second movie at the same time.

By the way, Commissioner Hiwatari doesn't exist in here and I changed a few things about the D.N. Angel and Cardcaptor Sakura universes. The relationships will develop later on in the story.

Disclaimer: D.N. Angel is owned by Yukiru Sugisaki. Cardcaptor Sakura is owned by CLAMP. Harry Potter is owned by J.K. Rowling. None of them are owned by me.

Claimer: I do own Seira though.

In the city of Azumano, all slept and awoke peacefully. Everyone was quiet and undisturbed. Everything was normal except in one place: Hikari Manor.

Satoshi walked down the stairs of the mansion he lived in, still wearing his black pajamas, looking emotionless as ever. His cold blue eyes were hidden behind his unneeded eyeglasses. His blue hair was messy that morning with a streak of blonde, which was where blue stands of his hair were between his eyes. He shot a glare at the girl in the kitchen, who turned around and smiled.

The girl in the kitchen was Satoshi's twin sister, Seira. She was wearing the girl's school uniform; a clean, white-collared shirt with a black necktie and a black, knee-high skirt. Her sapphire eyes drifted from her brother's face to his hair. She ran her fingers through her long, blue hair and bit her lip to prevent herself from laughing.

"Did you do that, imouto-chan?" Satoshi asked, pointing at the golden streak in his hair. Seira turned away and burst out laughing. Satoshi waited for her to stop.

He had waited five minutes until she finally stopped. His younger twin sister shook her head. She wasn't the one who put it there.

"No, it wasn't me. It might have been Towa. I was playing video games last night." His sister replied, returning to make her lunch and her brother's. Satoshi growled. Towa was the sprite that lived with them since their birth mother, Rio Hikari died giving birth to them. The sprite was like a sister to them and also a sort of partner-in-crime to Seira.

But Towa wouldn't do anything like that. She was too busy, cleaning out the attic the night before. Then, it must have been Seira then.

"Liar, Seira. You did this. And that's why you were playing with the blonde-highlights stuff….that Towa was going to throw away." Satoshi snapped. His sister sighed. She was caught.

She threw Satoshi his lunch as he ran back up the stairs to get dressed. Five minutes later, he came down, wearing a white-collared shirt with a black necktie and black pants. The twins grabbed their bags and left the manor.

Satoshi gave his sister a death glare as they walked out of their manor's district. He had to go through that school day with one streak of blonde in his hair. How he sometimes wished that Seira didn't exist. Seira grinned and walked ahead of him. It was going to be a great day for her.

"Come on, oniichan! We'll be late for our summer classes if we don't hurry!" She called, looking back at him.

A dark-blue haired fifteen-year-old young man sighed, looking up at the night sky. In England, it was time for rest unlike on the other side of the world (coughJAPANcough). He wore a dark robe with the sun on the front. On the back was a magic circle. Upon the circle, there was English writing and Chinese symbols. In his hand, he held a staff that was taller than he was. On the staff was a sun, where all the magic gathered. His name was Eriol Hiiragizawa.

He was practicing his magic before he noticed it was getting dark. Eriol returned his staff to its other form as a key. He put on his glasses. His dark blue eyes lit up and he ran his fingers through his straight, dark hair. He was expecting someone of great importance.

A second later, someone did appear from emerald flames in the fireplace. It was Professor Dumbledore, the current Headmaster of the magic school that Eriol attended: Hogwarts. A tall, thin and very old if you saw the silver of his hair and beard. He was wearing long robes, a long, purple cloak and boots. His bright blue eyes were looking directly through his glasses at the young man whose manor he was invited to visit.

"Professor, how nice of you to come visit." Eriol said, smiling.

"What an honor it is, Mr. Hiiragizawa, to visit the home of one of two reincarnations of Clow Reed, one of the most famous sorcerers of the Wizarding World." Dumbledore answered, taking a seat on an armchair, across from Eriol's.

Suddenly, the expression on their faces became serious. Eriol was like Dumbledore's spy of outside Hogwarts. Lately, Dumbledore had sent him to check in on his old friend, Sakura Kinomoto, the master of the evolved Clow Cards; and the-boy-who-lived, Harry Potter. Both went to Hogwarts for both education of magic and for their protection.

"Professor, is Voldemort really after Sakura and Mr. Potter?" Eriol asked. Dumbledore nodded.

"I'm afraid so. After what Professor Snape told me before I got here, I'm sure that they aren't the only ones that Voldemort is after." Dumbledore stated, putting his hands together. Eriol looked into the now red fire in the fireplace. Why hadn't he had seen it coming? Then, he remembered he gave half of his magic to Fujitaka Kinomoto, Sakura's father and the second reincarnation of Clow Reed. That was why.

"Do you have any clue who the people are?" Eriol questioned, looking back at the Headmaster of his school after a long silence. Dumbledore nodded again. Eriol raised an eyebrow.

"Yes, I do. In fact, Professor Snape told me. Their names are Satoshi Hikari and Daisuke Niwa."

In the town of Tomoeda, Sakura Kinomoto awoke at seven-forty in the morning. Kero was still asleep. He was probably playing video games again. She jumped out of bed and shrieked "HOE!". If she didn't hurry, she'd be late for her summer classes at Seijyu High School. She took summer classes with her friends because she was in Hogwarts, a magic school, for most of the year.

She brushed her shoulder-length, auburn hair. Sakura quickly got into her uniform: a white-shirt with a black neck-tie and a brown skirt. She grabbed her bag and left a note for Kero on her dresser. On her way down, she took her lunch and some toast before she ran out the door.

"Bye Dad. Bye Oniichan." She said as the door slammed shut. She ran directly to the school while chewing her breakfast. When she reached the school gate, she crashed into someone. Before she hit the ground, the person had caught her. It was Syaoran Li, a friend from China.

He helped Sakura up and smiled. He had amber eyes and chestnut brown hair that was neatly cut. Syaoran was slight taller than Sakura. He was wearing the boys' school uniform: a white-shirt with a black necktie and brown pants.

"You're in a hurry. Scared of being late again, Saku?" He laughed. Sakura looked at him. He had used her nickname, the one that Syaoran himself made up. Sakura playfully punched him and dragged him to their class on the second floor of the campus. When they got there, Tomoyo Daidouji was there to meet them.

She was the same as always, thinking of new outfits to make for Sakura to wear. Her purple hair was still reached her waist. Her amethyst eyes still sparkled like there were stars in them. She was wearing the same outfit as Sakura.

"Well, both aren't late. The teacher isn't here yet." Tomoyo explained. Sakura felt relieved. If she was late again, she'd be in huge trouble with her teacher. She walked to her desk and sat down. She was still tired so she decided to put her head down and rest for a while. But she didn't know that little nap would take longer than she expected.

"The Clow Cards….where are they?" Someone asked. The voice was cold and hissed when it stopped talking.

A short figure, head bowed down faced an armchair that faced the other way. "I don't know, my lord. But I shall keep looking."

The figure looked up. The fire in fireplace became brighter when the man in the armchair waved his hand. Another man walked into the room. He was tall and pale. He looked like someone. Someone Sakura had met before.

"Master, Wormtail. I have located the two boys like you asked. I have also have a clue to where the Clow Cards might be." The pale, new-comer announced. The short figure with his head bowed down winced.

"Well done, Lucius Malfoy. You will be rewarded. Now, where could they be?" The cold voice asked.

Lucius smirked. "All are somewhere in the country of Japan."

Sakura awoke with a start. Syaoran was staring at her. His hand on her back, shaking her to wake up. Tomoyo let out a sigh of relief. Sakura stood up and saw that class was over. She was asleep the entire time.

"Class is over. Just be happy that Kaseda-sensei didn't catch you asleep in class. You know what he'd say if he did." Tomoyo said, looking out of the window. Sakura hung her head. Should she tell them what she saw in that dream? But it would only make them worry about what would happen at Hogwarts.

'Maybe, I should tell Yue and Kero.' Sakura thought, walking side-by-side with Syaoran and Tomoyo on their way home.

Meanwhile at Sakura's place, Yukito came over with Toya. When Fujitaka left the house, Yukito was surrounded by Yue's wings and transformed into his other self.

"You saw it too, didn't you?" The Judge asked. Kero nodded.

"Yeah, I did. Volde-wart or whatever is after the Sakura Cards. Sakura has to watch out when she goes to that magic school now." said the yellow stuffed animal. Yue looked at the Guardian of the Seal and then, the empty case of the Sakura Cards. Their mistress had taken them with her like always.

"He's after two other boys besides the famous Harry Potter." Yue stated. Kero nodded again, taking a bite from the pudding that Sakura had left out for him to eat.

"Why do you think he's going after 'them'?" questioned Kero. Yue crossed his arms. He didn't know either. He returned to his temporary form without warning Kero, who had to freeze until Yukito left Sakura's room to talk to Toya.

'That was close. Yue better warn me before he does that again.'

Satoshi avoided the gazes of everyone including his fan girls. Seira coughed out a laugh as class began. The red-haired guy in the front of the class raised his eyebrow and smirked. His name was Daisuke Niwa, a friend of both Satoshi and Seira.

Satoshi tried to make those blonde strands of hair not visble. Unfortunately, his sister had to the strands that covered his forehead, making it harder for them to go unnoticeable.

After class, Satoshi cornered Seira before she left the second floor of the campus. He looked a little pissed off from what Seira could tell.

"Why do you keep on making my life a living nightmare?" He asked, grabbing her by the arm when she tried walking away. Seira struggled to break free, but couldn't escape her brother's grip. She turned around to face him.

"Isn't that what younger sisters do? They make life as their siblings know it a nightmare." His twin sister replied. Satoshi gave her an icy glare. As always, she wasn't affected. She was used to it. But something happened that neither of the twins expected. An invisible force pushed Seira off her feet and against the wall at the end of the hallway, which she had her back to.

Satoshi didn't snap out of his sudden trance. Seira looked at him from her position and shook her head. Another invisible force blasted Satoshi off his feet. He flew backward, smashed right into the other wall, opposite to his sister and landed face down on the floor.

"That's really gotta hurt." said a red-haired boy that they both knew so well. Daisuke Niwa had seen the entire thing. Seira stood up and looked at him with shock all over her face. Satoshi hid his expression by going all emotionless.

"You…s…saw…ev…everything?" Seira stuttered. Daisuke nodded. Seira leaned against the wall and felt her forehead. She better be dreaming. Satoshi and herself didn't have powers like that. They were normal fifteen-year-olds. But that was where she was wrong.

"Just as I thought. A witch and a wizard like me." Daisuke muttered as he walked away. Seira and Satoshi watched him, hoping that he wouldn't tell anyone about it.

The boy-who-lived woke in the middle of the night. He had a dream about seeing Voldemort, Wormtail and Mr. Malfoy. He didn't know someone else half-way around the world had the exact same dream as well. The emerald-eyed boy, Harry Potter sat up. An owl was light tapping on his window. It was an owl from Hogwarts with his letter from school and supplies list.

Enclosed in the envelope was also a letter from Dumbledore.

Dear Harry,

I ask of you to watch out for yourself this year. I believe that Voldemort is looking for you, to kill you. But I fear you are not the only one. I cannot tell you who else could be in danger. This is all you need to know. Now, don't leave your aunt and uncle's house until you are picked up by either Sirius, Professor Lupin or the Weasleys.

Professor Dumbledore

Harry angrily threw the letter onto his bed. Dumbledore was treating him like a child again. He wasn't a child anymore. Harry was fifteen, not five. He pulled out his wand and pointed it at the bed. He prepared to cast an 'Incendio' spell, a spell to start a fire. He hesitated. No one underage was allowed to use magic outside of school.

Harry dropped his wand and collapsed onto the floor. He wondered who the others in danger were. Maybe, he'd meet them in Hogwarts. Maybe or maybe not.

Daisuke came home and his mother, Emiko greeted him. She was so cheerful and perky as always.

"Oh Dai-chan! Did anything interesting happen at all?" She called from the kitchen. Daisuke dodged a couple of traps that his grandfather set up and entered the living room cautiously. His eyes met his mother's as he nodded.

"Yeah, I found out that the Hikari twins are like us."

Emiko dropped what she was holding and looked at Daisuke. The Hikari twins were a wizard and witch? They born from a woman named Rio Hikari, an old school friend of Emiko and were of the Hikari clan. A clan that created various artworks including two of the most dangerous ones in both the muggle and wizarding world. Emiko knew everything about Rio until the moment of her death.

"Rio…Rio, why did you have to be part of the Hikari clan?" She whispered, going back to what she was doing. Daisuke bowed his head and walked up the stairs, taking the family pet, Wiz with him. When he reached his room, he saw a letter with a strange seal on that back on his desk.

The letter was addressed to him and written in emerald ink.

"No way…this can't….be!" Daisuke yelled, "MOM! DAD! GRANDPA!"
