Mai Mishou is a Pretty Cure character in the first spin-off series, Futari wa Pretty Cure Splash Star. Like her predecessor Honoka Yukishiro from Futari wa Pretty Cure, she is reserved and formal, but unlike Honoka, she prefers the arts over science and has a more gentle and innocent nature. Her entire family seems to be into science however, her father is an astronomer, her mother is an archeologist and her brother, Kazuya, wishes to become an astronaut when he grows up. To support this, they live in an observatory.
Mai is reserved and studious, however she is also passionate. Mai is very observant and aware, often noticing subtle details that could have been neglected by an average observer. If anything inspires her, she draws it in her sketchbook. Unlike her predecessor, Mai is more high-spirited and personality wise being closer to her partner Saki Hyuuga, which makes them easier to become friends than Nagisa Misumi and Honoka Yukishiro. Her name put together can translate to "beautiful flying dance".
Mai has long dark purple hair worn down with part of it pulled up and has dark purple eyes in her civilian form. As Cure Egret her hair gains purple coloring and is worn in a full ponytail. As Cure Egret, Mai introduces herself as "The Radiant Silvery Wing Cure Egret!" whereas Cure Windy she introduces herself as, "The Scented Wind on the Earth, Cure Windy!"
Mai has long purple hair and eyes. She holds her hair up in a small bun, while the rest of it falls over her shoulders.
- The Japanese spelling "Iiguretto" (イーグレット?) can mean either "egret" or "eaglet", two different birds. Toei's official merchandise of this character also switches between "Egret" and "Eaglet". Most fans call her "Cure Egret", which is probably more accurate, based on her white wing symbol and also for the fact that the egret has a deeper symbolism in Japanese culture than the eaglet does.
