Hinata, Himawari

日向ひまわり

The story's female protagonist. She was rescued by a ninja bearing an odd mark on his neck. Since that event, she has sworn to become a ninja. At the start of the story, she had been restrained and flown on a military jet before being rescued. She is also known as the girl sent by her grandmother to the ninja training school.
She meets Marikoji Hayato, the male lead, after a training mishap (hang-gliding on a kite) causes her to crash and hang from the gate pole. From then on, she addresses him as "Hayato-dono" (Master Hayato). Her sole dream is to become a great "Kunoichi" (female ninja), even though her classmates find her annoying and unskilled.
