Nike Lemercier Ifrikia Edit
Nike is the youngest princess of the four princess of the Rain Dukedom. As a child Nike had difficulties summoning the rain and wind so she was often sad. Regardless Nike never gave up on learning. As she grew up and trained, she always took the harder path and hurt herself. Even then she never gave up. Her grandmother said "It would hurt her more." when Nike's cousin Kitora asks why does not she just give up on summoning rain. She is clearly the most beloved of the four princess to her grandmother. She is also considered to be the best and most talented as she is the only one who can summon both rain and wind together.
In exchange for autonomy, one of the four princesses of Rain Dukedom was to be sent to the Sun Kingdom to marry their King. The youngest princess, Nike was to be sent after she lost in a game against her older sisters. Nike is also very strong, proven when she beat up four of the palace guards. Nike comes to love and care for the young Sun King.
Optimistic, understanding, and stubborn, but caring. Nike quickly gains the people's affection as well as Livius, who clearly loves her. She is said to be more popular than Livius among the people in the Sun Kingdom as she seems to interact with them on a regular basis and helps them out whenever she can. She will also avenge herself, if she believes that she has been done wrong. For example, although Rani originally wanted to kill Nike and almost succeeded in doing so, Nike forgives him, but she also beats him up for carrying out the order of assault on her life. Nike also tends to be a bit clumsy as she occasionally steps on Neil's foot by accident when he helps train her on how to dance.
- Nike is only 1½ older than Livi in the Manga. But, in the Anime Nike is 4-5 years older than him.
- She is stronger than her Grandma Tohara but her powers were sealed.
- Nike and Livi's mother: Sheila, have the same facial structures except for the color of their hair and eyes.
