(Aqua Regina) (You)
*13 years ago, year 1999*
You are Leon Seiryu. The last remaining member of the Seiryu clan. Which once was the clan of the mightiest warriors to ever exist. You had a mother, a father, a brother that had the same age as you, a younger sister (3 years younger) and an older sister (1 year older). When you were 5 years old, your family and your clan were murdered by an extremely powerful demon named "Dark Dream" (think of a fusion between Nightmare and Black Heart) and his three groups of followers, The Band of Seven (Inuyasha), The Juppongatana (Rurouni Kenshin) and The Darkling Lords (Visionaires: Knights of the Magical Light). The village where you lived had impenetrable barriers. Outsiders could only come in if either, the barrier was lifted or the outsider was in the company of someone from of the clan. Thus you had no idea of how the enemies had entered the village.
You saw everything. No one was supposed to be spared. All the men were tortured and brutally killed, while the women were raped, tortured and, only then, killed. And, what was worse, when the demons attacked your house, you found out something horrible. You found out how the enemies had entered the village. Standing there, besides Dark Dream, was your brother, smiling. You knew what that meant. He had betrayed you and the clan. When they were leaving, the only words you managed to say to him were:
"Why, brother? Why?"
But, as the last amount of life within you began to fade, you heard a voice calling you.
"Can you hear me, little one?"
You could hear the voice. From the way it sounded, it was female, no doubt. It sounded gentle, caring and warm. But you were very weak so you couldn't move very much.
"W-who are you? What do you want?"
"Fear not, little one. I'm not here to harm you."
At that moment, the woman revealed herself to you and you felt an aura envelop you. And, before you knew it, you were completely healed. The woman was beautiful, to say the least. Her hair was golden in color and reached the end of her back. Her eyes were sea-blue. She had what looked like a crown on her head and a scepter in her left hand. She was dressed in what looked like roman robes.
"Please, little one, listen to me. You need to keep living."
"Why should I? I have nobody. Almost every one I cared for is dead. And the only one who's still alive betrayed me. I have no reason to go on."
"That's not true."
"How so?"
"The demon that led this attack is planning to do what he did to your clan to the rest of the world."
"That's not possible. My family nearly killed him."
"True. The fight with your family inflicted a big defeat on him. But he will recover. And when he does, he'll be even stronger than what he was now."
"And you want me to fight him, don't you?"
"Yes. With the proper training, I think you can defeat him, in the future. I can help you."
"How? How can you help me? Who are you?"
"My name is Aqua Regina. And I am the goddess of the sea."
"The goddess of the sea?! But, if your a goddess, why don't you simply destroy or vanish that Dark Dream?"
"Because, right now, I am not strong enough to do so. I am only a spirit. I can heal and teach you to control your powers. But I can not directly interfere with humans or other creatures. Not yet."
"What do you mean "not yet"?"
"For me to regain my power and to be able to vanish Dark Dream, the seven mermaid princesses must reunite, unify the power of their pearls and summon me."
"Seven mermaid princesses?! Mermaids are real?!"
"Yes, Leon. They are."
"How do you know my name?"
"I always knew. I have been watching you since you were born."
"I see. You said they are seven mermaids princesses. So, if I'm guessing right, each one represents one of the seven seas and each one has a pearl, right?"
"Exactly. You are very smart, despite being so young."
"Thank you."
"You are welcome. So? Are you going to help me? I won't force you. But you must make your choice now."
You didn't even needed to think about it. That monster had killed your most beloved ones and he planned to do so to the entire world. You couldn't let that happen. Not to mention that you wanted to avenge your clan's death. Also, despite the fact that what your brother did was beyond monsterous, you wanted to know why he did it. You had to do this.
"I have made my choice."
"What have you decided, Leon?"
When she asked that, you kneeled in front of her.
"I will help you, Aqua Regina-sama."
She smiled at you and teleported you to a world where you could train all you wanted, without risk of causing harm to something or someone.
