Waking up in the fog of memory, the only thing Chisaki is familiar with is her own name and a dark ball that cannot be opened.
She settled in Evergreen City in the Kanto region and became the youngest teacher at Quartz Academy. She taught students day after day, but she was always confused about her lost past and the secrets hidden in the silent dark ball.
The peaceful days ended with Team Rocket's sudden covetousness - their clear goal was directed at the ordinary but loyal big-tongued baby beside her.
This crisis was like a key, turning the gears of her destiny.
In order to protect her friends and pursue the truth about her identity, Chisaki resolutely resigned from her teaching position, picked up the familiar yet unfamiliar Dark Ball, and embarked on the unknown world of Pokémon as a trainer.
This is a journey to retrieve memories and an adventure to face the truth. When the end of the journey kicks off, she will discover that her lost past is far heavier and more dazzling than she imagined.
