"So you are Iachi's twin brother? You look more interesting than him. " Aini said with a smile.

"I heard that." Iachi said as Aini sticked her tongue out to Iachi then turned to Aichi.

"So,... " Aichi couldn't continue cause he doesn't know how to call Aini.

Aini knew what Aichi is think right now as she chuckled. "It's okay, Aichi. You can call me Aini. You don't need to be so formal." Aini said as Aichi felt a little comfortable. But Aini's face turned serious. "We don't have time to talk. I need to examine you, Aichi." Aini said.

"For what?" Aichi said in shock.

"Come on!" Aini said as she walked to the other room while everyone follow her.

Shizuka bit her lip when she looked at all of machines and chemestry stuffs at that room as she turned to Aini. "What are you going to do to Aichi?" Shizuka ask.

Aini turned to her, "To know how powerful he is now." Aini said.

Shizuka grit her teeth, "This is too early. He is too young-... "

"Sorry, but I can't disobey. Aichi is ready now. He can't keeping it forever. There is a time he need to release it." Aini said assertively. "I know you are worried about your son but you can't be this overprotective to him. He need to be stronger." Aini said as Shizuka just look down.

"Wait, what is this all mean?" Aichi ask but Iachi approaches him and pull him into in front of monitors. Iachi stick many wire on Aichi's body while Aichi still confuse of what he is doing now.

"What are you doing?" Kourin ask in worry.

"It's okay. There's nothing to be worried about. This is just an examine, Brother Aichi will be fine. Maybe." Iachi said as Aini give him a glare while Iachi look away.

"You guys already know about this news, right?" Aini said as a hologram screen appear and it shown about the accident and a spark ice. Everyone nod as Aini turn to Aichi. "Aichi, do you think there is something weird about that accident?" Aini ask as Aichi nod.

"Of course, it's weird. It happened suddenly without logical process." Miwa said as Aini nod.

"That's right. But it's not happened on its own." Aini said as everyone except Iachi and Shizuka shock.

Aichi look at the screen as he watches the accident. He sees his hand. His hand. His eyes widen in realization. "It happened because of me?" Aichi said as everyone except Shizuka, Iachi and Aini turn to him in shock.

Aini nod as Aichi look at his hand in shock. "That's why we need to examine you, Aichi. We need to know when your powers came out." Aini said.

"What powers?" Naoki ask.

"What are you mean it's happening because of Aichi?" Kai ask.

"You're not going to hurt him, right?" Kourin ask.

"This is just an-... " Aini pause.

"From the beginning, we were confuse for what you talking. You didn't even explain everything. Tell us what is going on!" Misaki said.

"So you want to know the truth?" Aini ask as everyone except Iachi and Shizuka nod. "Okay, I'll explain after this examination." Aini said. She press a button as a glass tube appear and surrounding Aichi until the glass tube become a cage.

Iachi frowned seeing it and starting to get nervous as he turn to Aini. "Aini, I think this won't work. In the beggining, I thought-... " Iachi pause.

"Iachi, calm down. This is just an examine not to make Aichi turn into a chicken." Aini said as Iachi gulped and stare at Aichi in concern while Aichi look back at him with confusing and worried face.

To make Aichi not nervous, Iachi gives a hand signal like saying: "You-gonna-be-alright-,-brother-Aichi-.-Maybe." But Aichi getting more nervous.

"I think I doubt that I'll be fine." Aichi said as he starting to cold sweat. He look down and seeing something come out. Vines. Many vines appear and wrap around Aichi's body as it start squezzing him lightly and slowly. Aichi grit his teeth but he is not scream and he struggles to break free.

Everyone got worried seeing him slightly in pain. Aini seems to confuse and start a little panic while Iachi try to calm everyone. "I-It's okay, guys... um,... he'll be fine. Maybe." Iachi said while everyone ignore him.

"Would you stop saying maybe?" Aini shout.

Iachi give a signal for Aini as Aini press the button and all of the vines stop and turn into millions of green sparkles. "I knew it. His powers are too powerful. He can't summon it or control it. He-... " Aini pause when Aichi looks like talking but everyone can't hear it because his voice is blocked. Aini turn on the speaker so everyone can hear what he says. "What is it?" Aini ask.

"Can I get out now?" Aichi said as Aini just nod. Aini press the button and the glass tube is lift up from Aichi.

"Yeah, you can get out but the examanation still not finish. There's still more step that we have to do." Aini said as she take out a long sheet of paper. The paper is very long until it touches the ground. Everyone shock seeing it. "Before that, I think I have to tell you guys a little explanation about Aichi." Aini said as she turn to Shizuka. "Mrs. Sendou can explain too." Aini said as Shizuka turn shock.

Everyone stare at Shizuka. Shizuka is kind a nervous to tell them but their eyes defeat her nervousness. She just sigh. "... A-A... Actually, Aichi... has an elemental powers." Shizuka said as everyone except Aini and Iachi shock. "He got his powers from his grandmother, Aura Sendou. Not only Aichi who has an elemental powers. Iachi, Emi, and his other relatives have it too. Even me." Shizuka said as Aichi and Emi shock.

"I have it too. But I never feel it." Emi said.

"Your powers is hidden inside you. You have to find it yourself and control it. It's kinda hard to consume it so you need to have a special training to do it. Right now, we all know that brother Aichi can't use his powers because he didn't consume it and his powers is released without his control. In other words, his powers came out on it's own." Iachi said.

"Like that accident, his powers was suddenly released on it's own. But it was a good thing that it released at the good time. Aichi's powers released on it's own means that Aichi is ready to take over his powers and that powers is ready to be controlled. But I think that Aichi's powers is not released on it's own. Maybe it's because Aichi suddenly used it without realizing what his doing or Aichi able to use it because there's something that make the powers come out. We still don't know yet. That's why we need to examining him." Aini said as everyone nod in understanding.

"We will tell you guys more but first we need to go to step 1." Iachi said.

Step 1: Touches the elements

"So, Aichi have to touches the elements to make sure that Aichi can use his powers by touching the elements or not." Aini said as he turn to everyone then to Aichi.

Right now, they are at the forest and Aichi is standing in front of the tree, still confuse. "C'mon, Aichi! Touch it!" Aini said as Aichi touch the tree. "Then concentrate to make that tree grows." Aini said as she lift her hands up high.

Aichi take a long breath and close his eyes. He opens his eyes again and try to make the tree grows. Aichi seems very hard to try it then he give up. "I can't do it. It's very hard." Aichi said as he walk back. Everyone just sigh in dissapointment.

But suddenly, Aichi stumbled by a rock and bump into another tree. He pull himself away from the tree with his hands touching the tree. His hands seems glowing a green colour light as he look at his hands. Not long after, the tree suddenly grow taller and Aichi got lift up.

Everyone shock seeing it. "Wow, cool!" Aini said happily while everyone glare at her. "What? Just saying." Aini said.

Aichi screams in fear as the tree keep taller and he even starting to reach sky very high. He can't look down or even release his hands from the tree. His hands still glowing an it makes the tree didn't stop growing.

Suddenly, Iachi appear striking the clouds as he fly high with his purple wings to following Aichi. His wings claps more stronger and faster. Finally, he reaches Aichi and pull him from the tree.

The tree stop growing when Aichi release it. Iachi fly down with Aichi on his arm. When he landing to the ground, his wings dissapear and turn into millions of sparkles as he put Aichi who still standing with his hands still at the same position when he touches the tree.

Iachi frown in concern as he look at his twin brother who seems whimpering. "Bro, are you alright?" Iachi said as Aichi shook his head. "You can put your hands down now." Iachi said but Aichi still froze. Iachi turn to Aini. "I think you are right, Aini. His powers too powerful." Iachi said.

"Yeah, but we still didn't know the process of Aichi's powers. Maybe we should very examining him inside and out. But from now,... " Aini said as she look at Aichi who still froze like a rock. "... Maybe he need to rest for a moment." Aini said as she point at Aichi.

Step 2: Scream

"Okay, what it has to do with scream?" Miwa ask.

"Well, scream sometime important for elements. Watch this!" Aini said as she look at Iachi who already preparing a shield. Aini take a breath. "HYAAAAAAA!" Aini screams as her hand glowing light blue light and punch the shield but it's too srong until Iachi been throwed and crashes the wall.

Naoki jawdrop seeing the scene. "I think I understand why she is scary." He said.

"So, the screams sometime can make the elements come out. It's like an emergency call. But you guys need an energy to do it too. And now, we need to see if Aichi can do it." Aini said as she look at Aichi.

Aichi seems very nervous as he look down. No doubt, Aichi was almost go to the space because of his powers. Iachi walk toward him and stop in front of him. "Bro, I know this is very hard but you have to do it. It's okay I'll be fine." Iachi said as Aichi look at him. Iachi is very dusty and many little rock on his body but he still smile to his twin brother.

Aichi just nod as Iachi preparing his shield. Aichi screams and punches the shield but sadly it isn't strong enough and Aichi wince in pain as he hold his hand that seems turning red. Iachi shock as he put the shield to the ground and hold Aichi's hurted hand.

Iachi accidently twist Aichi's hand harder as he realizes what he's doing. Aichi screams in pain more louder as his hand glowing blue light and accidently (maybe) punches Iachi who didn't prepare himself. Iachi been throwed and crashes 5 walls as the walls all have hole.

Aini close her mouth with her hand in shock as she walk towards Aichi. "Ouukh! Aichi, what have you done? You hurt the walls. That's so mean." Aini said sadly and angrily but softly.

"Hey, I am the one who is hurt, you know." Iachi said who more dusty than before as he walk towards Aini.

Step 3: Connecting with the elements

At night at the waterfall

Everyone is sitting on the ground full of fresh green grass with brezzing wind touch them softly while Aichi is... sitting on the rock under the waterfall, pouting. "So, what should I doing right now?" Aichi said as the water pouring on his hair and body. His clothes even got wet.

Aichi is wearing dark blue shirt, long dark blue buttoned jacket, dark blue pants, and dark blue sneakers. It was Iachi's other clothes but it fit with Aichi. It just for a while then Aichi will wear his own clothes.

"You have to connecting with the elements. That clothes will be perfect to connected with water since it dark blue too." Aini said. "And it make you more hansome and cool." Aini whispered as she take a picture at Aichi. "To be honest, I'm your fan, Aichi." Aini said.

"No one wants to know your privacy business." Iachi said with his hands in front of his cheeks as Aini glare at him with a red thick mark on her head and preparing her fist.

Aini calm herself and turn to Aichi. "Anyway, we will see if your powers come out when you connected with the elements around you. The only think you need to do is... take a long breath... " Aini said as Aichi just do what her says.

Aichi open his left eye. "Wait, this is almost like a training than examin-... " Aichi paused when Aini shush him with a glare and Aichi close his left eye again.

"... Concentrate... " Aini said. She lower her voice so that Aichi can concentrate easily. "Now, I want you to let your soul connecting to that water. This can be hard, Aichi. But I'm sure you can do it." Aini said. Aini stare at Aichi, hoping he can do it. And then, Aini sees something come out from Aichi. White, familiar, and... transparant. "Aichi! I didn't say you have to let your soul out of your body!" Aini shout.

After Aichi's soul back to his body

"Sorry, it just your words have many meanings." Aichi apologize.

"It doesn't mean you have to let your soul out of your body. I even more confuse how you do it." Aini said as she sigh. "Anyway, what you need to do is to deep your conciousness." Aini said as Aichi frown in confuse.

"How-... ?" Aichi ask.

"Close your eyes and imagine that you are touching the water. You very need full concentrate and focus." Aini whispers as Aichi close his eyes like what she said.

Aichi is in very full concentrate and he is imagining. He feels the touch of the water and his feeling... But suddenly, Aichi seems to be shocked by something like an electricity. He still close his eyes but in his mind is very in chaos. Aichi sees many unfamiliar images on his mind.

The image when he play on the rain with Iachi, the image when he enjoying the touch of the rain, the image when he start being sad because of something, and the image when suddenly he can controlling his elements. The elements of water. Then many sad unfamiliar images appear with shadow that make them blank.

Iachi suddenly feel a pain on his head as he clutch his head which make everyone shock. Aini turn to Iachi then to Aichi. She saw the water start shaking and suddenly the water start surrounding Aichi like sparkles.

Aichi seems holding his screams but his mouth seems force to be open and many tears start streaming down from his face. With all of sudden, Aichi is been lift and floating with the water still surrounding him. Aichi can't even moves his body and his tears start to join the water to surrounding him.

Kourin and Shizuka close their mouth in shock while everyone except Iachi shout his name in panic. "Aichi, wake up! Open your eyes!" Aini shout but it doesn't work at all.

Aichi's hand move on its own and he seems going to use the water to attack. Aichi's hand point at Aini as the huge water going to attack her. Aini dodge the water but it makes Aichi use both of his hands to attack. "Guys, he's out of control. Just run away! I'll take care of this." Aini said as everyone start running away. Kourin is hesitate to run because of her worried about Aichi but she has to thrust Aini and running away.

Aichi seems can't hold his scream as he screams and his hands slowly raise up. Aini widen her eyes in panic as the shadow surrounding her. Everyone look turn around when the day seems turn dark. They shock after seeing tsunami is start to approaching them.

Everyone protect themself when tsunami is going to touch them. Aini run to them and raise her hands to make a big light blue shield until it protect all of them. The sound of slashes water ringing in their ears.

The water is strong enough to make Aini start weaken to supporting the shield and Aichi still can't control himself. The shield start to cracked as everyone start panic.

Meanwhile, a shadow turn around when the shadow heard Aichi's scream. The shadow run fast to the location as the shadow stare at Aichi who still floating. The shadow arrive and stare at the shield that still been attacked by the water then to Aichi.

The shadow make an ice stairs to reaches Aichi. When the shadow finally reaches Aichi, the shadow quickly hit Aichi's neck harder as it make Aichi open his eyes and fainted. Aichi fell but the shadow catch him and put him to the ground.

The water stop attacking them as they open their eyes and Aini finally can rest. They see Aichi is lying on the ground with many sweat on his head.

"He's very does powerful. No wonder grandma believe in him." They heard a female sound as they see a red haired girl near Aichi. Aini who still exausted smile to the girl.
