Kureha Suzuka

A young prodigy who joined the police force at the age of 18 with the rank of Lieutenant, she is posted in the Tokko division. Her symbiont tattoo, like Sakura, was on her right shoulder. Her preferred weapons are two daggers that have two retractable blades. Originally having brown hair, she changed it to yellow after the massacre as a means of moving on after her parents were killed by Phantoms and the death of her younger brother, Akito, at her hands. Kureha is very interested in Ranmaru, especially on his looks and his history. In fact, she had kissed him when they visited the cemetery where her family was resting.

However, nothing more would come of this when the relationship between Ranmaru and Sakura began to flourish further in Episode 10...though she would still tease and idley flirt with Ranmaru though the rest of the series (Source: Wikipedia)
