Alice Rebecca Archelaus is a soft, squishy, and adorable three-year-old who is dearly loved by her grand household. However, her world crumbles when she discovers that she is merely a replacement for the real "Alice," who died at birth. This revelation plunges the innocent child into a profound depression, and her household begins to fall apart.
After two long years, Alice emerges from her despair, but she is not the same child as before. She has regained the memories of her past life, where she lived as a 30-year-old corporate slave and Fantasy Otaku in Japan! Living in her dream world of magic and monsters, Alice wields the wisdom and spirit of a middle-aged woman to face her most pressing issues and, of course, learn to master her newfound magical abilities.
