That Name is Extraordinary! Strawberry Mask

Elizabeth's brother, Hendrick, who has the ability to hypnotize women when they look into his eyes, wants to marry Naeka because of her fortune and huge breasts. However, Elizabeth, not wanting her brother to marry her nemesis, disguises herself as the Strawberry Mask (even though people know who she is) to try to stop Hendrick from making Naeka fall in love with him because she actually wants him for herself.
