At unknown place

There is a castle with beautiful design and decoration. Inside the castle, a woman with long grey twin tail hair are standing in front of the window as she close her eyes. A weird and sinister sound is playing around on her head. Then a strange videos appeared in her head.

'No,... Stop it! I don't want to embrace that darkness. Stop!' A male voice sounded like he is suffer in her mind. In her mind, a boy is chained as he keep struggling. 'No... d-don't! DON'T!" The boy see a sinister smirk in front of him. A darkness start to enter his body through his eyes and chest as he screams in pain with his eyes widen and slowly his eyes turn white.

The woman gasp as she open her eyes. She touch her chest as she look down. "Why am I always had this bad feelings? It makes me worried sick about 'him'" She thought.

She turn around when she heard many footsteps behind her. Three shadows stading there. Two boys and one girl. "Have you found him yet?" She asked.

"No luck. We haven't found the clue either. What should we do now?" One of the boy asked.

The woman just look down and stare at them. "Just keep searching! It's okay if you can't find him. The three of you should be arrived at Tokyo when it's your turn to show yourself. And if you seen any suspicious, tell me as fast as you can." She said.

"But I don't think he could be somewhere around. We heard the news about his dead then why are we keep on searching him? He could be already became a skeleton or a sand." Said the other boy as the woman frowned and turn sad.

"What are you saying that?" The girl said to the boy who just said that.

"What? It's the fact. Sometimes you have to believe in police, you know." The boy said back.

"But still we have to prove it that he's not die."

"Okay, there. Listen up!" The three shadows look at the woman. "He's might be right. But I still have an unknown feelings about this. I'm getting often got all of this weird feelings. It makes me worried." The woman said as she sighed. "... You can leave now. Continue on searching him."

"Understood." The three shadows said together as they bowed a little and walk away.

The woman turn to the window again and stare at the sky. "I have promised to you. I will use all of my power to help 'him'. He'll be someone what you wished for. He will." She thought.

Meanwhile

"Elemental... what?" Kamui asked.

"Elemental Alter Ego. It is an ability to make the elemental inside you to take over your body. What in front of you is an elemental of nature who take over brother Aichi's body. The elements have a duty to protect themself with brother Aichi's body. And brother Aichi can order them to take over his body everytime he needed and order them to let him take over." Iachi explained.

"The elements have their own personality. Just like Alter Ego. Nature is cheerful, only doing what he has to do, and someone who likes playing and staying around with natures. That's why he doesn't want to go back cause he doesn't like unnatural place or the place where he can't find nature things. We can know which elements that take over Aichi's body by seeing his eyes and personality." Aicha explained.

"They can also use their own ability. Plus, the chance of Aichi's elemental power to come out will be huge and the power will be tame enough to be controlled when the elements inside him take their role. The elements can take over Aichi's body when they have a contact first with Aichi or Aichi already know that they will take over him." Aini said.

"Wait, did Aichi know this?" Kourin asked as Aini shook her head. "Then how can he contact with the elements when he himself didn't know this kind of stuff." Kourin asked again.

"Well, Aichi's power is uncontrolable. And maybe this ability accidently activated because of last night when Aichi's power almost killed us. So this ability is uncontrolable. Aichi has to make a friendly connection with the elements so he can control this ability easily and the elements want to obey him. If he doesn't, then he won't be able control them." Aicha explained.

"One question, please!" Misaki said. "Iachi, what is your elemental power?" Misaki asked.

"Well, I'm only have light elemental power." Iachi said.

"Aini said, If the twin sibblings have great connection to each other and have a same elemental powers, then the twin sibblings can feel a pain from each other." Misaki said.

"So?" Iachi asked.

"How do you guys can be like that when you two have different elemental power? Aichi only has nature, ice, and water elemental powers while you only have light." Misaki asked.

"Brother Aichi doesn't only have three elemental powers." Iachi said as everyone except Aini, Aicha, and Aichi shocked.

"Then how many he has?" Naoki asked.

"Well, technically he has 15 elemental powers." Aicha said.

...
...
...

"EEEEH?!" Everyone said in shock.

"F-f-fifteen?!" Ren exclaimed.

"That much?" "TM" Reiji and Eiji exclaimed together.

"Then how can you, Aini, and Aicha only have one?" Kai asked.

"Um,... maybe I have two. Rainbow and gravity. But maybe gravity doesn't really an elemental powers. Maybe it almost like my ability but it's still a powers. Physical powers." Aini said.

"I think maybe there's a reason why Aichi has that much. Maybe he got through many things back then when he was younger. Suprisingly, 15 elements are more likely called all of the elements." Aicha said.

"Whoah, cool! Aichi is awesome." Ren said happily.

"And maybe because of that Aichi can't control them cause they are so much. And the reason why Iachi and Aichi have the same elemental power is because Aichi has light elemental powers too even though he has the other elements." Aini explained.

Everyone nodded in understanding. They suddenly heard a yawning sound as they turn to Aichi. "Geez, I'm getting bored hearing those explaination. Can you guys just go away?" Aichi (Nature) said boredly as the birds fly toward him and perched on him.

"Nature, we're not intend to disturb you or anything. We just only want to explain." Aini said softly. "And if you bored, then how about we training?" Aini suggested.

Aichi or Nature look at her for a second then nodded as he landing on the ground while the birds fly away from him. "Okay, there. But don't ever think I won't do this seriously! I'm not like your so called friend, Aichi who can't control his own power." Nature said.

"Oh, yeah? We'll see about that. I wonder if his elements can't control their powers either." Aini said as she crossed her arms.

"Heee, he's agree with it? I thought he will reject it since he want to play around with nature." Shingo said.

"The elements know when they have to be serious. Every elements very want to training cause they very want to be strong. And if this is when the elements doesn't really have a great or strong connection to each other like friends or family, maybe they want it to be the strongest than all of the elements in Aichi's body." Aini explained.

"But who will train him, Aini?" Iachi asked.

Cricket sound.

"Um,... I don't know." Aini said.

"What are you mean you don't know?" Kourin asked.

"Me and Iachi have to examining Aichi's powers that lost control last night while Aicha has to unfreeze the lake that she froze last night." Aini said as Aicha giggled awkwardly because of what Aini said.

"What about Mrs. Sendou? She can train Aichi, right?" Miwa suggested.

"No, I can't. I can't let all of you see my powers." Shizuka said as everyone Aini, Nature, Aicha, and Iachi shocked.

"But why, Mom?" Emi asked. "Does your powers are dangerous?" Emi asked again.

"No, I just can't do it." Shizuka said as she look away. Everyone stare at her for moment before frowned in dissapointment.

"Can't be just one of you except Aicha who training Aichi while the other one examine his powers?" Asaka asked.

"The problem is... " Iachi paused as he and Aini glared each other. "... Who will be the one who train him?" Iachi continued.

"You should be the one who train him. You're his brother." Aini said.

"Connecting with blood doesn't mean I can't connecting with my other self." Iachi said as he fix his glasses position.

"Er,... I don't understand that last one." Misaki said.

"Whatever it is, if you guys won't training with me, then I'll just go looking for some fresh air." Nature said as he about to go away but Iachi grab his collar. "Hey!"

"Sorry, bro. But you can't just go away without us. It's dangerous." Iachi said as he release Nature's (Aichi's) coat collar.

"I'm not a kid. I can take care of myself." Nature said as he pouted. "And stop calling me 'brother'! You're the one who said that I'm not your 'brother Aichi'." Nature said.

"Even though you're not my brother doesn't mean his body is yours. Just relax here for a moment. We will training, so don't worry!" Iachi said as he turn to Aini. "Okay, Aini. If we won't relented, then let's do something fair!" Iachi said as he take out something from his pocket. A Vanguard deck.

"You played Vanguard too?!" Naoki exclaimed as everyone except Aini, Aicha, and Aichi shocked.

"If brother Aichi playing it, then I playing it too. Aini and Aicha also play it. Mine is Royal Paladin. But we're not going to cardfighting. The rule is: if someone got the higher grade card, then he/she will be the one who examine brother Aichi's power." Iachi said as he shuffle his deck before point the deck to Aini.

"Why me first?" Aini asked.

"If you give up, then I win." Iachi said.

"Okay, fine." Aini said as she draw a card and Iachi did the same after her. They stared each other before revealing their card to each other. Both of it is grade 2 as they shocked. "What the? Same grade." Aini exclaimed as he turn to Iachi. "Can't you shuffle it seriously?" Aini yelled.

"I already shuffle it seriously. Don't blame me! I don't even know the cards in order." Iachi said. "Nevermind. Draw again!" Iachi said as Aini stare her card for a moment before throw it away then draw the card again faster. "Don't throw my cards like that!" Iachi yelled but Aini just ignore him and pouted.

Iachi sighed as he draw a card. He know that he can pick the card that Aini just throwed away. They revealing their card. Again, they got same grade. The next turn,... still same. The next and next again,... same. "Maybe we should do something else." Aini suggested with 😑 expression.

"Okay, let's do a rock, paper, scissors! But before that,... " Iachi point the cards that are scattered behind Aini. Aini just pouted and use her gravity power to lift the cards to Iachi's deck.

"Happy?" Aini said.

"Yeah, thank you." Iachi said as he put his deck to his pocket.

"Wait, can I ask something?" Asaka raise her hand as Aini and Iachi turn to her. "Why do you guys very want to win? Is it because you can't train Nature cause he's annoying and it will be hard to teach him?" Asaka asked.

"Hey, I heard that." Nature said but Asaka ignore him and continue to ask.

"Or is it because you guys very like sience until you want to examine so badly?" Asaka asked again.

Iachi and Aini thinking for a moment until they spoke together. "Because I like sience." "Both of them."

"Wha?" Iachi said as he turn to Aini.

"Well, yeah. I think it will be hard to train him since he is annoying and he might be doesn't want to hear me or even appreciate me." Aini said as she crossed her arms, pouting.

"Really, huh? Didn't she is the one who telling that the elements know when they have to be serious." Iachi thought as he sweatdropped. "Nevermind. Let's do it already!" Iachi said.

They start to put their hand behind their back. "Rock, paper, scissors!" Both of them said as they both use scissors. "Rock, paper, scissors!" Both of them use paper. "Rock, paper, scissors!" Both of them use rock.

"Would you stop copying me or I'll slap you." Aini said as she preparing her hand to slap Iachi.

"I didn't copying you, emotional girl." Iachi said.

Iachi and Aini start to glaring each other in anger. Their aura flared with an electric between their eyes. Miwa turn to Naoki and Shingo as he smiled. "Hey, Naoki, Shingo! Looks like you guys got a twin sibblings." Miwa said as he giggled.

"Haha, very funny!" Naoki said as he pouted.

Meanwhile, Nature is leaning on the tree with his hands behind his head. He just sighed seeing them glaring and fighting all the time. Everyone except Iachi and Aini just sit around doing nothing. They getting bored seeing them like that too. "Why are we here anyway? We just sit around like this." Ren complained. "Can't we just go home?"

"You know, I have to agree with Ren. There are so much people here." Kai said.

"You can go if you want. Your parents will be worried." Aicha said.

Some of them stood up and bit their goodbye as they walk away. Right now only Aicha, Emi, Iachi, Aini, Shizuka, Kourin, and Nature is on that place. "Fine. I will be the one who train brother Aichi. You just go ahead!" Iachi said in defeat. Aini nodded and smiled as she come back to the lab.

Iachi is now face to face with his brother. Both of them standing a little far away from each other. "Finally I can do something a little chalenging." Nature said as he stretched his body for warming up and Iachi do the same.

Kourin look at Aichi then to Iachi. "I don't know what's going on or what's this all mean. How can Aichi got all of the elemental powers? Is it because when he was sealed where he got nature, fire, steel, ice, and dark elements from his surrounding? No, I don't think dark is one of his." Kourin thought. She turn to Shizuka who keep looking down.

Kourin and the others is far away from them. Emi is staring at her elder brothers before looking at her hand. She very think what kind of elemental powers that she has. Aicha notice her as she check on her. "Emi, are you alright? You seem very think of something." Aicha asked as Emi turn to her.

Emi immediately shook her head, not wanting to worry her. "I'm fine. Don't worry! I just a little worried about Aichi. He will have the most hard time on his life. He'll be fine, right?" Emi asked back.

Aicha a liitle frowned but she smiled. "I don't really actually know. But I'm sure he's fine. We all know Aichi is tough. Iachi will do a simple training first so don't worry." Aicha said as Emi nodded and smiled. But Emi look back and frowned again.

Iachi's POV

I watched brother Aichi or Nature in front of me. I don't really know how this Elemental Alter Ego works. When the other elements will take over or when they will let brother Aichi take his body back?

When we finished warming up, I spoke. "Okay, bro-... I mean Nature. We will have a simple training but you still have to very focus in this one." I said as Nature nodded.

The wind start to blowing us a little hard as I lift my left hand. The purple light start to gathering on my hand and it cover my hand until my hand shine. I shift my left leg a little as I throw my shiny hand to the ground.

The ground around me shine. Then suddenly, many purple light balls appear from that shine. The light balls fly toward Nature then they surrounding him like tornado.

Nature look at all of the light balls as he use his power. Many vines around the light balls as they destroy all of the light balls by turn into tornado as well.

I can see Nature smiling to me behind that tornado vines like he is trying to say 'It's-that-all-you-got.' I smiled in statisfied seeing him chalenging me. "Aini is right. They know when they have to be serious. Guess this is why she said it will be annoying. What an emotional girl." I thought.

My left hand shines again as the purple light sword appear. I run toward Nature and attack him. The tornado vines dissapear as Nature uses a long spiky vine like chain with spiky ball of vine that attach on the vine. He use it as a weapon.

Nature swing it before attacking me with it. Fortunately, I got hit by the spiky ball of vine and I got throwen. I crashed one of the tree harder as everyone amuzed seeing the scene. "Is the elements have their own weapon, Aicha?" Emi asked.

"Yup, and their weapon is different." Aicha said.

Nature swinging around his weapon ( just like when cowboy swinging the rope) so that he will ready if I going to attack.

I stood up and smiled to Nature. This is almost like a fight than a training but I didn't give up yet. The more I get hit, the more I feel statisfied. Guess I will move to the next step of this training.

"C'mon, there! Giving up yet?" Nature said and smiled in undrestimately.

"You think so?" I said as we continue to training.

But not long after, I see Nature start to holding his head in pain as he screams. No doubt, brother Aichi might be trying to take over his body again. Maybe brother Aichi force himself without have a contact to Nature or even order them.

This is bad. If brother Aichi knows how to order them, then he will take over them easily without making him uses to much energy and Nature will help him take control. But it's very sudden and Nature is panic too. Everyone shocked and starting to worry seeing Nature in pain.

Then Nature faint as all of us try to wake him up but it's no use. Brother Aichi might be using his energy too much. Then we immediately get back to the lab as we carried brother Aichi.

A/n: You guys need to prepare for the next chapter. The adventure will nearly start. Oh, and here is my drawing ☝.I don't own Cardfight Vanguard. See you later.
