Zakuro Kurumaki

Zakuro Kurumaki is the first demon hunter employed by Enjin Hiizumi to attack Sakurashin Town, in which she attempts to retake Rin Azuma.

Zakuro ends up being defeated, reverted back to her old self and now lives and works at the Houran Ramen Store with Rin Azuma.

She has an over-bearing and sadistic nature, especially towards Rin and is willing to slaughter the whole town for the sake of getting more "toys" and protecting Rin.

In truth her sadistic personality only exists because she fell and became a half-demon, her real personality is close to that of Rin - very sweet and gentle. When the two were younger, Zakuro met Rin and offered her a home to live in and protection from the humans who chase her. The two bonded quickly and Zakuro taught Rin how to cook. When Zakuro fell she became abusive and sadistic towards Rin who would eventually run away and find her way to Sakurashin Town.
