Sengo Arai

⟨ What a disgusting dress! Everything here is covered in sequins that are out of place. Fe-fe-fe!! ⟩ – a 5-year-old girl loudly criticizes the seamstress. The latter, in turn, does not understand – what is the child doing here. You see, the workshop now belongs to Miss Arai. And the little girl is Miss Arai's daughter, Sengo. From now on, she will be more important here than the others. The girl has long liked the design – after all, they don’t sell normal ones in stores. After all, both her older sister and mother said that there are no things now, that a person will be elevated to an ideal. And that means such things need to be created!
Square or even cube beauty. This formula needs to be derived, because everyone must know it... both the poor and the rich, because the world deserves to be more ideal than the current one.

All subsequent years were spent trying to find a formula that would lead to the "true" beauty of people. To sew, to decorate, to add talent to the image - all is not enough. And then there is the modeling business, which prevented Sengo from realizing his dream.
Sengo is disappointed - because everyone around her will never understand this, they just have fun, laugh at each other. Middle school passed like that - without friends, even without enemies. Arai remained in their eyes a bland and boring doll of a mother... stupidity. All life passes as if on threads. It was surprisingly easy to cut them off...

Miss Arai: Sengo! You have to become a perfect model, because your appearance
simply superb... like a bud about to bloom.

Sengo: And I-I don't want to! This is boring, you don't understand anything. I already told you, and you keep repeating about the "model"... I'm fed up!!!

...A scandal occurred. Disgusting and loud.
Yes, suspiciously easy, considering how persistent Ms. Arai is in this matter. A very long punishment of silence.
It was hard, because mother and daughter were quite close...or so it seemed to Sengo? The situation seemed very strange to the girl, but liberating from the responsibilities imposed by her mother.
But it didn't matter anymore - now Sengo could freely distinguish herself as a future genius in the upcoming brilliant era!

opinion about Jiang:

Jianying! Our sponsor is rich and handsome, and even generous. Not bad.
But the fact that he exaggerates himself and pretends that he doesn’t understand anything is infuriating! He’s dumb.

opinion about Eiri:

He-he-he... He knows so much gossip that it's hard to wrap your head around. And working with him is not difficult, you just need good headphones so you don't hear alien nonsense.

opinion about Ada:

Ada!! Guys unfairly condemn her, she's a sweetheart! And her silly inventions can be tolerated, pff.

Sengo is the youngest child in a family that has had many things handed to her on a silver platter. She is an unpleasant person on the outside: capricious, quick-tempered, unpredictable in her emotions, and often uninterested in conversation.
Arai are easily bribed either with something tasty and chemical, or with something very expensive, especially fabrics and jewelry.
Also, Sengo is a real "Internet hero" who often ends up being a hater of what she considers "not perfect".
When she needs to gain something, she is capable of diplomatic negotiations, even though it makes her angry.
