Description
Kaoruko Tenkawa, also known by her magical girl alias Magia Sulfur, is a fourteen-year-old middle school student and a key member of the Tres Magia, the heroic magical girl trio dedicated to fighting the villainous organization Enormeeta.

On the surface, Kaoruko presents herself as a calm, easy-going, and refined young lady, a demeanor reinforced by her gentle Kyoto dialect. However, this polite exterior masks a much brasher, short-tempered, and fiercely combative true nature. She takes great pride in her abilities and is not hesitant to start conflicts, using goading and taunts against her opponents. Her true personality is notably foul-mouthed; following humiliating defeats or perceived injustices, she has been known to unleash vehement and extremely vulgar threats, even during a live television interview, which resulted in an abrupt commercial break. A sore loser at heart, Kaoruko is prone to both self-deprecation and seething rage when defeated, holding deep grudges and using these losses as motivation to train even harder.

Kaoruko's motivations are rooted in a pragmatic and duty-bound sense of justice. She possesses a very clear-eyed, cold view of the conflict with Enormeeta, believing that any member of the organization is an absolute enemy and that there is no room for sentimentality. This makes her the most intelligent, cunning, and realistically minded member of Tres Magia, often acting as the group's strategist and the voice of reason to rein in her more emotional teammates. She feels a strong sense of responsibility to live up to the expectations of the children and fans who support them, consciously maintaining her public mask of a kind and gentle heroine. This dedication is so profound that she was originally recruited into Tres Magia after a monster attack, during which she did not flee but instead flew into a violent fury, beating the creature to a pulp with nothing but nearby debris.

In the story, Kaoruko serves as the pragmatic anchor and tactical leader of the Tres Magia, providing a sharp contrast to the pure-hearted Haruka Hanabishi (Magia Magenta) and the duty-bound, somewhat masochistic Sayo Minakami (Magia Azul). Her key relationships are complex and often fraught with tension. She shares a particularly volatile rivalry with Kiwi Araga, also known as Magia Leopard, as the two instinctively hate each other and devolve into insults and fighting whenever they meet, even in their civilian forms where recognition inhibition prevents them from knowing the other's true identity. Her relationship with Haruka is more nuanced. While she initially acts as a cold realist next to Haruka's innocent optimism, a significant shift occurs after an accidental kiss caused by Magia Baiser, which awakens unexpected feelings of jealousy and possessiveness in Kaoruko. She becomes flustered by Haruka's casual physical contact and is deeply affected by Haruka's unwavering trust in her, creating a complex, budding romantic tension that contrasts with her otherwise aggressive personality. She is also classmates with the protagonist Utena Hiiragi (Magia Baiser), unaware of her secret identity as the villain she fights, and finds herself appreciating Utena's boundless, positive energy as a friend.

Throughout the series, Kaoruko undergoes notable development, primarily in her emotional world. While she begins as a purely pragmatic fighter focused on victory, her experiences and close calls begin to reveal a more vulnerable side. Her reaction to Haruka's La Verita transformation, which drastically alters Magenta's personality into a promiscuous and assertive version of herself, horrifies Kaoruko, turning her into an emotional wreck and driving her to protect Haruka from having to use that form again. This incident highlights her deep, and perhaps suppressed, care for her teammate, moving beyond simple friendship into a more possessive and emotionally dependent territory. Her tendency to hide her true capabilities also informs her growth, as she learns to balance her image as a hero with her authentic, battle-hungry self.

As Magia Sulfur, Kaoruko's abilities reflect her dual nature as both a defender and an aggressive fighter. She typically plays a defensive role, utilizing her magic to create powerful, tanky barriers to protect Magenta and Azul. However, her true offensive power lies in her ability to manifest two large, cool sets of gauntlets or giant arms that drastically boost her physical abilities and deliver brutal close-range attacks. This consumes a significant amount of magical energy and presents a more feral, intimidating image, so she often refrains from using it in public to avoid frightening young children whom she wants to inspire. She is a capable fighter even before transforming and has a sharp, analytical mind that helps her see through the schemes of Enormeeta. Her evolved form is known as Magia Sulfa Blitz Angel, which unlocks even more combat potential. Despite her formidable power, she has notable weaknesses, including an intense chapodiphobia, the fear of octopuses, which can cause her to freeze up completely during a fight. In her civilian life, her favorite pastimes include playing first-person shooter games and enjoying junk food, while she despises octopus, even refusing to eat takoyaki that contains it.
