"Skipping class again?"

A sudden voice of a young lady stuck in the silence of a windy day. It was the same rooftop where Cynthia and the alter ego conversation took place. The sudden intrusion of this young girl who appeared behind the staircase stopped the argument in that instance.

It has been more than twenty years right after the end of the new beginning in human history. Humans called themselves neo-human, a new breed that has acquired god's strength, a power that had unrivaled both god and demon in the past.

As they begin to rebuild the world from scratch, civilization multiplies. The world advanced to return to modern society within these twenty years. The human race almost ceased to exist, making their knowledge of history buried with salvation. All the history archives almost went gone, but humans found themselves having no struggle in advance to a present world.

There is no conflict, nor does war have to be waged. Humans carefully take all the hard lessons they've learned in the past and manage to rebuild whatever has been lost during the sudden catastrophe on earth. Historical education, vast knowledge of medication, and futuristic technology have resurfaced in society. Yet, neo-humans swore not to kill, and conserving the peace was always remained their top priority.

It was a windy day with a clear, bright sun. We could see a pair of girls staring at the blue sky on the rooftop. The wind blows gently as a breeze runs through her long hair that reaches a height of her waist, her mind carried along with the wind. Without any worries and thoughts, she slowly closed her eye and tried to indulge herself in this beautiful peak of the day.

The other girl approached Cynthia, slowly pulling her baby hair behind her. The windy day interfered with her vision.

Both girls have displayed a fine body figure with a goddess look-alike facial. Their uniform, almost similar to a sailor navy theme Japanese style, or called sailor fuku, combines several variations like neckties, bolo ties, and neckerchiefs on their top, colored with dark blue color.

Their white shirt matched the cloud color on this most beautiful day, and they donned a dark brown checkered blouse that stretched almost to their thigh, along with a white shoe and a midnight blue long loose stocking.

"What are you doing here too? Don't give me lame excuses that our homeroom teacher asked you to come and drag me back to his boring lecture session. Give me some new ideas if you wish to move my feet from this sacred ground." Annoyed by the presence of her friend, Cynthia tried to chase her away.

"Come on, don't be so cold to me. I want to talk with you. It didn't have to be any particular reason."

"You've done more than enough already to disturb my mood right now. I want to stay calm accompanied by the weather today."

"What happened? Does the inherited power from your father has awoken again?!"

"He's not my father!!"

Tension caught them in silence after a vociferation from Cynthia. She's triggered by the last word spoken to her. Both of them kept silent for quite a while. But at the end of it, the girl who just thoughtless spoke the forbidden word pulled her breath. She walked past Cynthia while leaning her wrist on the barricade and stared at this great afternoon view.

"Sorry for what I've said just now, Cynthia. I am just worried about you. These few days, I seldom see you come back to our house. At school, I rarely saw you attend any of our classes session."

"I'm fine. Thanks for being thoughtful to me. I'm sorry too for my sudden rise of voice, Rin."

Look like they often got into a dispute over trivial matters. Cynthia was the carefree girl who kept looking at the sky view, and Rin was the girl who just came up looking for her.

Both of them were like siblings. They were daughters of deities who saved the entire human race from the edge of salvation. Although they didn't share the same bloodline, Cynthia had affection toward Rin, as she saw Rin as her younger sister and had taken good care of her since their childhood.
