Atsuko Sasaki

Fondly known by her nickname "Acchan," Atsuko Sasaki was the protagonist's closest companion back when they were ordinary students in Japan. She possessed a laid-back, peace-loving demeanor and spent much of her free time completely immersed in otome games, ultimately setting the entire plot in motion by introducing "Fortune Lover" to her best friend. Although she appeared to be an introverted daydreamer who kept to her creative inner world, her dedication and emotional warmth toward her friends were absolute. This profound connection beautifully transcends the boundaries of life and death, as it is later revealed that she reincarnated into the same fantasy universe as Sophia Ascart, allowing her to gently watch over and support Catarina under a brand-new identity.
