She was sent from the Ichikawa Institute to join 007, where she's partnered with Kuze. She has the ability to "see" a person's last memories. She's smart, but very naive almost to the point of stupidity due to her upbringing. Most of her past remains a mystery, but what is known is that she was stunted from living a normal life. She's confident without the defects of being cocky or self-absorbed. She's not very sensitive and faces everything with a strong front (that is unless its ghosts). She's easily a cute relatable character who slowly and genuinely falls for someone.
