Description
Kohaku Tsukishiro, born August 23, 2001, hails from a lineage of witches and wields magical abilities. As a teenager, she stands 160 cm tall, characterized by purple hair in a ponytail and amber eyes, often wearing an azurite necklace; her hair grays in old age.

Attending Minamigaoka High School in 2018, Kohaku earns a troublemaker reputation. Her frequent magical experiments disrupt school activities and damage property, causing fear among classmates and requiring written explanations to teachers. Despite these mishaps, she genuinely intends her magic to bring happiness to others, though spells sometimes spiral out of control. She studies abroad in England during this period but returns immediately upon learning of her granddaughter Hitomi's arrival from the future.

By 2078, as an elderly witch, Kohaku witnesses Hitomi's emotional distress and loss of color perception. Concerned, she uses time magic via an artifact called the Stardust Clock to send Hitomi 60 years into the past. This action, driven by wisdom and empathy, aims for Hitomi to encounter her younger self and find healing.

Reuniting with Hitomi in 2018, Kohaku forms a close friendship, insisting on being called by her first name instead of "grandmother." She joins the Photography Art Club with Hitomi, proposing its renaming to the "Magic Photography Art Club" to integrate magic. Kohaku focuses on refining time magic to ensure Hitomi's safe return to her original timeline.

During high school, Kohaku has a relationship with Shōsei Ichiyanagi, who later becomes her husband and Hitomi's grandfather. Ichiyanagi creates the Stardust Clock and gifts it to Kohaku, making it central to her later time manipulation. Her journey shows a transition from a well-intentioned but impulsive youth to a compassionate elder using magical expertise for familial healing, highlighting the responsible application of magic and intergenerational bonds.
