Akari Taiyou is a girl who takes after her late mother Hinata as an apprentice fortuneteller. She lives with her aunt and uncle, and her cousin Fuyuna Shinzaki, who is jealous of the attention Akari receives. One night, Akari has an apparent dream in which she is attacked by a giant plant monster, and sees herself as a magical girl killing it. When she awakens, she finds Fuyuna lying dead in her bedroom. The events of the previous day then repeat themselves; this time Fuyuna is completely absent, and Akari and her relatives appear to have no memory of her. Akari later goes to the fortunetelling house where she works to find it has been set ablaze by a middle-aged man, who transforms into a giant, flaming monster and attacks her. Akari transforms into a magical girl wielding the power of the Sun Tarot and fights back, but is overpowered and knocked unconscious. She is rescued by three other magical girls, who kill the monster and bring her out of the burning house.
