Plot
Ririka Moriya is a bubbly, clumsy 4th grader who has a crush on Nozomu Kanou, a transfer student from England. On her 10th birthday, Nozomu gives her a magical nurse cap, which allows Ririka to transform into the heavenly guardian, Nurse Angel. Nozomu later tells her that his real name is Kanon, and he comes from the planet Queen Earth, which has been overrun by the evil Dark Joker Organization, who has tarnished Nozomu's world through mass pollution. He was sent to find the legendary Nurse Angel, who would save both Earth and Queen Earth from destruction by finding the Flower of Life (命の花 Inochi no Hana). With help from Nozomu and her friend and neighbor Seiya Uzaki, Ririka learns to fight as Nurse Angel to protect her friends.

However, love to her of Seiya is not noticed at all.


 * Ririka uses the magical phrase, "Holy Power, Holy Prayer, be here!" (聖なる力、聖なる願い、ここへ！) to transform into Nurse Angel. In the manga she both says this line and places the nurse cap on her head, while in the anime the cap simply appears. Ririka seems to become somewhat older after she transforms. Her hair is longer, and she has a more serious demeanor. Nurse Angel's primary weapon is a baton, and she can perform a wide variety of energy attacks. Her source of power for these attacks is a powerful healing agent called Green Vaccine, which is made from the Flower of Life. In the anime, she has a finite supply of Green Vaccine, and once it is gone there is very little she can do as Nurse Angel.

Seiya Uzaki

 * Seiya Uzaki (宇崎星夜) is Ririka's next-door neighbor and her childhood friend, is the son of a doctor, and aspires to follow in his father's footsteps. He is about the same age as Ririka, and in the same 4th grade class. Though he is not good at study and is the mood maker of the class, the turn of the head is fast. He is very much the mischievous young boy - he likes video games, playing sports, and teasing Ririka. On the other hand, he is honest with himself about his affection for Ririka, and will go to any length to protect her. While in the beginning of the series Ririka and Kanō-senpai hide their secret war from Seiya, he eventually finds out and is entrusted with power and a mission by Kanon and succeeds him and becomes Nurse Angel's number one supporter and grows up manlily. He uses Psionics and, his clothes do not change into a Battle costume. He uses a boomerang in the manga, has put on clothes of the Queen Earth only once. Seiya is the source of most of the show's one-liners and cool quotes.
