Imari is a supporting character in the world of Shinga, appearing as a small, white tanuki. This creature is often initially mistaken for a simple raccoon but is in fact a magical being and a loyal follower of the region's former ruler, Himemiko. Imari has a distinctly animalistic appearance, complete with cat-like ears, fangs, and a tail, and is noted to have yellow eyes.

The character serves a crucial role as a guide and herald of the story's central conflict. Before her mysterious disappearance, Himemiko entrusted Imari with a single, vital mission: to search for and find a human girl from another world. This directive implies a deep sense of trust and responsibility, making Imari the catalyst for the arrival of the protagonist, Yuzuki. Upon locating Yuzuki, Imari explains the chaotic state of Shinga, the power of Himemiko's blood, and the emergence of creatures called Yakuma, providing her with the necessary context for her unexpected situation.

In terms of personality, Imari is characterized as an adorable and somewhat anxious companion. The character is driven by a strong sense of duty to find Himemiko and restore peace, and earnestly seeks help from the protagonist to achieve this goal. As the story progresses, Imari remains close to Yuzuki, offering guidance and information about the various warring clans, including the motivations and territories of leaders like Hideyoshi Toyotomi and the Sanada clan. Beyond this role as a messenger and informational anchor, Imari does not possess any notable combat abilities, instead functioning as a non-combative ally who facilitates the protagonist's journey and interactions with the warlords. The core of Imari's development is tied to the fulfillment of Himemiko's final wish, serving as the thread that connects the vanished leader to the new heroine.
