Author's note: It's my first fanfic so I hope you guys like it and leave some reviews good or bad it doesn't matter to me.

Disclaimer: I don't own DN Angel but I do own some of the characters that will pop-up in the upcoming chapters including in this one.

Words in italic are what Dark and Krad say when talking with Daisuke and Satoshi in all my chapters, while normal ones are for the others mostly Daisuke, Satoshi and the other characters

Another morning in Azumano Junior High. There was a lot of students coming, the sun was shining brightly, the birds were chirping happily and people were heading to their appropriate classrooms. A girl with red hair passed back and forth looking for the proper classroom.

"Oh where the heck is that stupid classroom?!" the girl shouted, making a lot of students stare at her.

Did you already forget that you're in the same class as that creep, huh Sei? Said a voice from inside the girl's head.

"Oh right class 2-B, sorry I forgot thanks for reminding me Seira" Sei said while heading towards the classroom

Whatever, I'm going back to sleep so don't bother me again! Seira said with a little anger with it. "Fine, do what you want" Sei said smiling.

A while later Niwa Daisuke is seen running through the hallways shouting "I'M LATE!!!!!" but suddenly he bumps Sei when he turned to the corner. "Oh sorry I didn't notice you there are you alright, miss?" Daisuke said a bit embarrassed "No it's fine I wasn't even looking where I was going" Sei said embarrassed as well.

'Great luck Sei! You met the person you weren't allowed to meet in the past ten years what do you think your mom will say? Sei said in her thoughts. I guess I should be lucky that he didn't recognize me' she thought. Um, sorry to interrupt you Sei but your classroom is that way Seira said interrupting Sei "Huh? What? Oh no I forgot!"

Minutes later…

"Alright settle down class we have a new student joining us today, please stand up and introduce yourself" the teacher said. "Hey Dark it's that girl I bumped into a moment ago" Daisuke said to Dark Really? You know if you look at her real closely she sure looks a lot like you but with long hair. Do you think you guys are related? Dark said teasing Daisuke a bit Sei stands up "Hi my name's Sei Niwa I'm 14 years old and I just hope that all of us will become friends!" She said while blushing a bit. That really answered my question Dark says in an embarrassed tone "You don't think she's really related to me do you, Dark?" Daisuke asks Dark a bit shocked; Well she does have the same surname as you, maybe she is. Dark says in his usual tone of voice. "Dark, you're not helping!" Daisuke said a bit irritated. Then ask her later Dark says "Yeah I guess that would work". "Ok you may seat beside Daisuke so please take you seat now Sei" the teacher said in a happy tone "Yes ma'am" Sei responds looking a bit depressed "Why do I have to be his seatmate why? Why? Why?!!!" shouted Sei in her head Quit shouting why don't ya! I'm trying to sleep here! Seira said in a very angry voice "But it's just—" Another word and I'll annoy you and get you into trouble on your first day of school! Seira said in a really angry voice "Waaah! Don't do that! Alright I'll stop just don't embarrass my ok Seira?" Sei says in a defeated voice Good so don't bother me again got that?! "Yeah I got it"

After school Daisuke is seen running towards his house to tell his parent's about the new girl Sei but when he got there a huge shout "AAAAAAHHHHHHHHHH!!!" it was Daisuke shouting when he saw his new classmate at his own house sitting on the couch drinking a cup of tea.

"What the heck is she doing here Mom?!" Dai said in a really shocked voice.

Wow that's what you don't see everyday Dark whispers while trying not to laugh.

"Now don't be so rude at your twin sister Dai-chan" Emiko says in a calm way

Twin Sister?! The two said in unison (Dark and Daisuke to be exact)

"What didn't she tell you while she's at school?" Emiko asked

"Sorry mom but I forgot since he might have been too shocked" Sei said in a apologizing way

"It's fine dear. Oh by the way how are other Hikari artworks you stole?" Emiko said in a cheerful tone

"Fine including the Mirror of Time is in a good condition when we sealed it" Sei said in her normal tone (as in the same tone that Dai uses when he's happy)

"W-wait what did she mean by 'we'? And what do you mean by the other Hikari artworks? Is Sei also a thief?" Daisuke said in a really confused way

"Oh I almost forgot to tell you. Daisuke, Sei also has an alter-ego like you and she really looks a lot like Dark since she's his twin as well but has a different attitude and well you'll see!" Emiko responded

"But why haven't I seen her for the past ten years mom?" Daisuke asked trying to stay calm.

"That's because—" Emiko stopped

"That's because we heard that some of the Hikari artworks were found somewhere in Tokyo so I had to go there and be the Phantom Thief so well a friend of our mom trained me the same way you were trained but I did turn into Seira a little bit earlier than you. To be exact she's been with me since last year I don't know how but her abilities haven't reached it's fullest until I'm 14 but since I just turned fourteen a couple of days ago she's got her abilities back to its fullest" Sei said then finished her tea.

"But why did you come back?" Dark suddenly asked when he and Daisuke switched places.

"Easy because a lot of the Hikari artworks are beginning to awaken that's why I've got to help you seal all of them" Seira said when she switched with Sei as well

"Is she trying to capture you as well?" Dark asked.

"Yup and she's as worst as Krad as usual" Seira sighed then stood and approached Dark. "Do you think Krad will ever remember?" Seira asked looking a bit sad.

"Remember what?" Dark asked since he's confused.

"Never mind, it's alright forget that I said that ok, Dark?" Seira said and sighed again

"Yeah. Sure whatever" Dark responded a bit annoyed. What's with her suddenly mentioning Krad like that? Dark said to himself.

"So are going to steal something again?" Seira asked Emiko

"Yea But this time I'd like the two of you to steal it together" Emiko said with a cheerful look on her face.

"So what are we going to steal?" Dark asked Emiko who was preparing their clothes

"You guys will steal the Kagami no Unmei at 11 p.m. ok?" Emiko said after preparing the two thieves' outfit to wear at the theft.

"Really? No wonder you need the two of us for that" Dark said while giving Seira a smirk.

Here we go again Seira said to herself. Do you think she'll show up? Sei asked worriedly "I guess especially when Krad's there too" Seira told Sei in a really soft voice. I hope it doesn't go to a very bad fight Sei said in a worried voice "Yeah I hope so too"
