Chelsea

One of the main female characters. She is actually a princess from a magical world who came to earth looking for a husband. She also hides a secret identity which is that she is a magical girl. Her accidental meeting with Kazuya became her resolve that he was fated to become her husband, especially since Kazuya found out her true identity. She is very obsessed with Kazuya, by constantly daydreaming about him and hates Hina for always getting in her way (which she doesn't know is the guardian heart). She hates the guardian heart for always disturbing her from getting close to Kazuya.
