Heart Aino (愛乃 はぁと Aino Hāto?) is innocent and full of energy, with a smile that is simply contagious. Ever since she was small, animals have been drawn to her, and much to her mother’s dismay, she frequently brought stray cats and dogs home. Heart truly believes that love can solve any problem. Even though she means well, her desire to spread happiness sometimes causes her to get involved in other people’s problems at times when they’d rather be left alone.
Heart has always been able to see Arcana. In truth, this ability is pretty common in young children, but as adults tell them that "such-and-such" is not real, most of them begin to losing this ability. The ability to see beyond the physical world is directly linked to a person’s beliefs and imagination. When you stop believing in Elementals, you stop seeing them. Luckily for her, Heart’s mother always encouraged her to believe in them. Consequently, she has been able to interact with a vast number of Arcana. Her first (and her best friend among the Arcana) was Partinias. Because of her ability to get along with so many Arcana, Heart has been labeled as an extraordinarily rare Maiden by the Ministry of Elemental Affairs, which tries to keep a close eye on all matters related to the Elemental world where she sees something strange above the Tokyo skies and Heart decides to investigate up there.
