Calypso has experienced repeated reincarnation, and this is her 4th reincarnation.
In her previous lives, she always died before she reached the age of 22 and returned to where everything started. During her 3rd life, she discovered that when a dragon goes on a rampage, it distorts dimensions. Determined to use this knowledge, she plans to exploit the dragon’s power to return to her original world.
Currently, Calypso finds herself in a childcare story, where she encounters a man who she believes to be her father but doesn’t recognize her. Seeking his help, Calypso involves her "father" and family in her quest, turning them into unwitting allies in her journey.
