Description
Chikako Kurotori is the grandmother of the protagonist, Chiyoko "Choco" Kurotori, and a figure whose quiet presence holds significant weight in the world of Kuromajyo-san ga Tōru!!. Her real name is Thika, a detail that connects her directly to a past life far removed from her current role as an unassuming elderly relative.

In her youth, Chikako was a student at the Black Witch Public Academy, the very institution that trains the witches who inhabit the spirit world. During her time there, she was acquainted with notable figures, including the witch Melusine and Gyubid's grandmother's older sister, Gyubad. This background establishes her as a character with deep and authentic knowledge of the supernatural realm. However, her academic career was cut short; she was expelled for breaking one of the school's strict rules, an event that permanently barred her from returning.

This history shapes her role in the series, which is one of silent guardianship. Chikako is fully aware that her granddaughter Choco has become an apprentice to the black witch Gyubid, but she chooses not to reveal her own knowledge or interfere directly. Her motivation stems from a desire to respect Choco's privacy and allow her to navigate her secret on her own terms, rather than intruding upon it. Despite her hands-off approach, she is far from passive. Chikako frequently uses her expertise regarding the Spirit World to assist Choco from the shadows, providing help in subtle ways that go unnoticed by her granddaughter. She acts as a secret guardian, using her past experience to gently guide Choco through the challenges of her magical training without ever stepping into the spotlight.

While not flashy, her abilities are considerable. Her knowledge of the Spirit World is described as deep, allowing her to understand the supernatural events and beings that intersect with Choco's life. Her primary ability is not spell-casting in the present, but rather the application of this accumulated wisdom to solve problems discreetly. The key relationships in her life are defined by this quiet support. Her most important bond is with her granddaughter, Choco, though it is built on what is left unsaid. Her past friendships with other witches, like Melusine and Gyubad, tie her directly to the history of the magical world that her granddaughter now inhabits. Over the course of the story, the revelation that she was once an expelled student from the witch academy provides a crucial context for her character, transforming her from a simple grandmother into a former practitioner who understands the world of black magic from the inside. Her development is subtle but significant, as her secret past is gradually uncovered, revealing the depth of her connection to the story's magical foundation.
