In a mysterious realm is a faraway realm connected to different worlds, a realm where only living beings that the realm itself accepted, a realm where the guardians or so-called 'Overseer' lives to protect their homeworld from certain destruction.
Beautiful scenery at the valley and a giant tree called 'world tree' also is most unique to its own have spirit and many of them scattered in this realm. A tree connected to a different world protected by the guardians of the tree. There are multiple buildings with different styles with divisions between them. The 'World Tree' is connected to a unique set of worlds that is found in the void called 'Multiverse'.
At the northwest side of the world tree, a courtyard of a Cliffside Western-style house with beautiful scenery of a background, a beauty with pale silver eyes, long, straight, white hair and pale constitution wearing a black dress with an image of a golden phoenix while looking at the valley.
At the corner of the backyard an identical beautiful female with long waist black hair and a healthy constitution wearing a white dress with an image of a golden phoenix while looking at women with long white hair.
Female with white hair is wearing melancholic expression then sigh looks at the sky. Then the female with black hair show surprise expression due to sudden change and called out to female with white hair with a silvery and caring voice speak in an ancient language.
Female with Black Hair: "Little Sister?"
The female with white hair called little sister surprised at someone just call out to her and look at the female with black hair and reply with a gentle, low-spirited voice in the same language.
Little Sister: "Mm! Big Sister, why are you here?"
While looking at her and reply to her question with concern expression.
Elder Sister: "Just checking on my little sister because you are always looking sad from the past days without telling me why."
Learning what her elder sister trying to do and replies with grateful expression and looks at the sky then suddenly showing a happy expression.
Little Sister: "It was nothing, you don't worry about that anymore."
Elder Sister surprised to see her little sister smile as if she is waiting for someone she is deeply in love with. She looks at the sky and thought to herself.
Elder Sister: 'maybe something might happen very soon to change our situation knowing my little sister if she is like this, they're always a probability might happen that change our lives in the future.'
While the little sister looking at the sky happily then making the love-struck expression and thought to herself.
Little Sister: 'He is coming here at last ever since that day he came here while my sister is not around. And he will probably help get us out of this situation in this realm.'
At another location, far west of the World Tree, a western-style mansion with a beautiful garden at the backyard. Inside of the study room there a handsome male with the darkest blue, short, slick hair, and tanned, well-built body wearing a black semi-formal suit sitting in front of a desk and reading a file. Then he looks at one of the glass bottles with some kind of liquid at one of the shelves place in the corner of the study room. He raises his hand toward the shelves he looking at then flicks his hand then two small glass bottles shot out the shelf toward him. He looks at the bottles place on his desk and murmurs to himself.
??? : "It is almost time for me to give this to the rightful owner after he gone through those trails."
He stands from his chair then walks to the window and looks outside with a smile in his face and disappears from the study room.
Returning to the beauty with white hair murmurs to herself with expectation.
Female with white hair: "He is almost back once more from that trail and I have high expectation for our situation to be solved by him."
She ran to the mansion with a smile. And the beauty with black hair looks perplexed after watching her little sister while she thought something also entered to the same direction to her little sister with a calm face. No one knows what she is thinking.
