(POV-Narrator)
A year after Shira was born, Hiroyorozu Yuika, thei mother, divorced Sengaku Yoichirou and moved in US. She worked as owner of Lithium Arc Electric Company and its scientist that leads the research and development section. She already knew about her incoming fate so she is finishing her last and final stage of her work.
"It is almost done. I have no proof for these theories but if mathematics is in the table, it is perfect."(Yuika)
It contains all the scientific theorems that make up the universe. Explaining every physical laws, the origin and end of universe. Multidimensions, space-time, particle motion, dark matter, biological phenomenons, evolutions, and even the diverse worlds out there and souls. Sociology, politics, history, mythology, mathematics, arts, psychology, music, engineering, and languages. It is printed to 50 volumes in hard bound white cover. She only released the 25 volumes after omitting the knowledge she decided to entrust to her son and daughter. The name of these books are 'The Encyclopedia of White Knowledge Upon Compilations and Amalgations by Mankind's Collective History'. They shortened it to 'Hiroyorozu Yuika's White Notes'. White Notes for short. Upon publishing, she got awarded by numerous awards including Nobel Prize. She is also named as philomath, polymath, philosopher, and a great sage of modern era. Nonetheless, she moved at United Kingdom when Shira reached the age of three to educate her as a noble lady.
"Milady, a lot of 'dark' people are lurking to search for the complete volumes of White Notes."(Hinako)
"Tch! I only slipped my tongue once yet they blindly believed its existence."(Yuika)
"It is milady's fault though."(Hinako)
"Yeah, I know. Sorry about that. Can you eliminate them?"(Yuika)
"As you command."(Hinako)
Her chief and personal maid dashed stealthily to eliminate the pests that investigating her master's perimeter.
"Reinhardt."(Yuika)
"Milady."(Reinhardt)
"I have a job for you."(Yuika)
She gave him a bracelet which contains the encrypted copy of complete white notes. Both the printed and the digital copy. She burned the non-ciphered ones to prevent any leakage whatsoever. She made sure only her children can decipher it upon reaching their coming of age(A/N: adulthood).
"I wish they wouldn't have to use all those knowledge. After all, I left lots of incomplete theorems inside those. It is embarassing that I have to make them complete it."(Yuika)
"Milady, can't complete it?"(Reinhardt)
"It will take me twenty more years. I don't have much more time."(Yuika)
"Milady... You will not-"(Reinhardt)
"No. I will not find another path. This is the most certain way to protect them. I am a genius indeed. But I can be replaced. But they can't be. They are our priceless treasures without equal. Even it means sacrificing all things we have built for, we will not compromise on it."(Yuika)
"Milady is really same as Lord Sengaku."(Reinhardt)
"Ufufu... He is my prided husband I love after all"(Yuika)
She giggles innocently with a bright smile.
"Besides, our children are essential by all that exists. Their importance for the multi diverse worlds is without peer. Their lives have immense influence to it. That is needed by both mankind and gods. Their have something that none of us all have. We need them to survive no matter what."(Yuika)
"So this is not just milady's selfishness..."(Hinako)
"Yes. They are needed to live for the survival of the worlds. They will be entrusted of those kinds of great tasks. I beg you to support them."(Yuika)
Their master bowed to them with bottomless plea as proof of her affections to her children. They sworn with their lives infront of her that they will do as she had willed.
