Zakuro Kurumaki

Rin's first friend and the first demon hunter who made an attack on Sakurashin. Zakuro is a necromancer and is capable of controlling anything that was once living, but is now dead, along with other yokai. Being able to do this allows Zakuro to also control Rin's movements, whether or not she has her name tag on. Spoiler After the fight, when Zakuro entered the town, and also began working in the same delivery store as Rin, Zakuro was extremely fearful of being banished from the city and not being able to join. This fear continued on, even after she was officially made part of the population of Sakurashin. (Source: Wikipedia)
