Aika Fuwa (不破愛花, Fuwa Aika) was killed along with her parents one year before the start of the series; in the anime adaptation, it was stated that only Aika was killed, where it was implied that both Aika's mother and Mahiro's father had either lived or died by some other means. Aika was Mahiro Fuwa's adopted sister and Yoshino Takigawa's girlfriend, in which was kept secret. Despite being already dead, both are still far from overcoming her loss, with Mahiro determined to avenge her at all costs and Yoshino still claiming he has a lover. It is later revealed that she is the Magician of Exodus and, instead of being murdered, she committed suicide; the manga had also elaborated that she also killed her parents to ensure that that they won't stop Mahiro from finding Aika's supposed murderer. She is one of the protagonists of Zetsuen no Tempest.
Aika was considered to have a lovely complexion, told to Hakaze by Yoshino. She had light brown hair, about as long as to the end of her back. She has two thick, long strands going over each side of her shoulders and bangs.
As described by both Mahiro and Yoshino, she had a "bad personality" due to her cold and calculating personality. During her encounter with Hakaze, she mentions it herself that she does not make friends easily. Her classmates were quickly intimidated by Aika's presence because she was the Magician of Exodus. She knew too much about the world which distanced her from her peers.
However, Aika was a caring person to those she loved, particularly Yoshino and Mahiro. She chose to commit suicide, and went as far as to kill her own parents, in the end so that fate would be linear and Yoshino and Mahiro would not live in a world that the Tree of Beginnings determined for them.
She was shown to be extreme intelligent and insightful. Aika also had a penchant for quoting Shakespeare, particularly Hamlet and The Tempest. There also seem to be times where she can be dramatically eccentric as she declared herself to be the detective, victim, and murderer of the Mahiro's family murder case.
Aika was adopted by Mahiro's family; before her mother's remarriage, she was known as Aika Mayami. She went to school with him and also met Yoshino. Later, the two became involved in a relationship, but the two kept it secret, especially from Mahiro.
A year and a half before the story begins, Aika and her parents are found dead by Mahiro.
It is eventually discovered that Aika was a Mage of Exodus and that she was not murdered, but committed suicide instead.
As the Mage of Exodus, she had a lot of power stemming from the Tree of Exodus. In her battle with Hakaze, it is revealed that the more Hakaze uses the power of the Tree of Genesis, the more Aika can use her power in response. As a the Mage of Exodus, she is not required to make an offering as with other magicians. This allows her to overcome Hakaze's power in a duel.
They had a secret relationship together as boyfriend and girlfriend. After Aika died, Yoshino was actually very conflicted and completely devastated, where he fainted at home; however, he didn't show it in front of Mahiro who assumed Yoshino was not that affected by Aika's death. Aika had found it humorous that Yoshino was suspected to be the Magician of Zetsuen, a suspicion that continued to persist where, due to Megumu Hanemura's weak will behavior, Yoshino was suspected of having the heart of the Magician of Zetsuen; though this was confirmed to be completely false as, due to Aika's death, Hanemura was simply hastily chosen as the Magician of Zetsuen.
Mahiro was Aika's stepbrother and cared a lot for Aika. However, he thought of Aika more than a sibling and wanted to have a relationship with her, but urged himself not to. He was the one who found Aika dead.
Although she never actually got to know Hakaze and become friends, they met when Hakaze uses her power to time travel and discover who murdered her. After seeing Hakaze using magic, they meet and Aika introduces herself for the first time as the Magician of Zetsuen. Hakaze explained everything, from the murder to her confinement in the island to her actual situation. This is when Aika decided to commit suicide because to ensure that time would keep linear, the murderer should be ignored by The Tree of Beginnings, and, subsequently, by Kusaribe magic. The people capable of doing that were the Magician of Zetsuen and the Kusaribe clan members.
- Aika's character includes allusions to Sycorax from Shakespeare's play, The Tempest, which is a deceased character who appears in flashbacks and defines several of the relationships in the play. It also includes allusions to Ophelia from his other play, Hamlet, whose greiving brother desires revenge after her death.
- It has been revealed in the manga that her original surname was Mayami.
- Aika's name means "love flowers."
