Description
Maika Yoshikawa is the eldest daughter of the Yoshikawa family, known for her long lilac-colored hair which she often ties back with green ribbons. As the oldest sister, she is a capable magic user and takes great pride in cooking for her brother and younger sisters, a task she seems to genuinely enjoy.

In terms of personality, Maika presents herself as a caring and ladylike individual, but this demeanor has a distinct and powerful exception. She is intensely protective of her brother Haruo, so much so that others frequently accuse her of having a brother complex, an accusation that holds significant truth. Her usually composed nature is completely replaced by possessive jealousy whenever any female shows romantic interest or even simple closeness to her brother. This extreme devotion to Haruo is not a recent development. As a toddler, she subliminally brainwashed him in his sleep by repeatedly chanting a phrase to ensure he would stay with her, demonstrating the deep roots of her possessiveness. This jealousy is so potent that it can cause a physical transformation, changing her into a green-skinned demon when she feels especially threatened or envious.

Within the story, Maika's primary role is as a guardian of her brother's ordinary life. She is immediately suspicious of the witch Ayumi Mamiya's intentions when Ayumi enters their lives, viewing her as a potential rival and a threat to the family's secret and to her bond with Haruo. This suspicion drives much of her interaction with the main plot, as she actively works to obstruct any situation that might draw Haruo closer to Ayumi or the magical world. Her key relationships are centered on her family. Her dynamic with her younger sisters, Chiaki and Fuyuno, involves them both witnessing and often commenting on her extreme behavior. Her relationship with Haruo is the core of her character, defined by a combination of genuine familial care and an unhealthy, overbearing attachment.

Maika's development throughout the series is less about fundamental change and more about the consistent expression of her established traits. She is a static force whose actions are repeatedly driven by her two defining characteristics: her dedication as a homemaker and her obsessive protectiveness over her brother. Her notable abilities include the use of magic, though her most remarkable power is not a spell but her capacity for extreme jealousy, which can manifest as a monstrous transformation.
