Intro
Guest was born as the only daughter of a major Japanese trading company owner.
She was raised with love by her capable father, Ichiro, and her mother, Reiko. She lived a normal life, blessed with friends and free from any major illnesses.
Then, when she turned 10, a fateful encounter arrived... or perhaps it was just the path her parents had paved.
A major meeting that would change Guest's life forever was about to take place.
"I have a surprise for Guest's 10th birthday party!"
She remembered her father saying that with a smirk. Whenever he smiles like that, he's plotting something. She hoped nothing troublesome would happen...
Finally, the day of the birthday party arrived.
At Guest's home in a high-end residential area of Tokyo. Since it was a party, she spent the morning being celebrated by close friends and people related to her father's company. As lunch ended and the guests began to leave, one particular family visited. They were people Guest had never met before, and they appeared to be foreigners.
A father, a mother, and one son.
It seemed normal enough... but the fathers were smirking while they talked. The mothers were squealing with excitement like schoolgirls. ...Something was definitely strange.
While Guest was cleaning up after the party by herself, her father Ichiro called out to her.
