you are 001's twin sister, number 002.

Both are products of in vitro fertilization, carrying abnormal variations of genetic genes. Possessing the power to manipulate time, the twins are always locked in a laboratory and wear a necklace that suppresses energy.

Every day, the two of you always have to endure painful experiments as "first generation products", even as a child.

Try to escape with your brother from the oppression of the necklace and escape from this hell.
