Red Data Girl

Main characters

• Suzuhara Izumiko (鈴原 泉水子)
• Izumiko is described by Miyuki as a dull-looking girl with twin braids. Before beginning her first year of high school in Tokyo she wore red-rimmed glasses that were given to her by her mother. At the beginning of the series she is very timid and shy, and doesn't like to share her desires or opinions with others. However, as the series progresses she begins to change and becomes more confident. One trait that shocks most people that meet her is that she has lived a few years of her life without using electronics, because they used to break whenever she tried to. It is revealed in episode 2 that Izumiko is destined to serve as the vessel for a powerful ancient goddess Himegami (姫神) and will most likely be her final vessel. Later in the season, it is revealed that her mother gave her the glasses to block her vision, because she "sees too much". Without them she can identify spirit agents, ghosts, and gods; though they appear to her as frightening creatures covered in a black aura.

• Sagara Miyuki (相楽 深行)
• Miyuki is the son of Yukimasa and also a mountain monk-in-training. When he is first introduced he is very cruel to Izumiko and said that he couldn't believe a goddess was in such a dull girl like her. However, after seeing her powers and learning more about her he began to soften up towards her. Even after Yukimasa gave him the chance to go back home he decided to stay with Izumiko and protect her. After moving to Tokyo together, Izumiko and Miyuki grow closer; but Miyuki doesn't believe he can truly protect Izumiko. He believes he is weak and can't even take care of himself. Miyuki has a very strained relationship with his father, whom he hates. At first when Miyuki refuses to serve Izumiko, Yukimasa took him into the woods it is implied that he beat him into submission. Yukimasa often calls Miyuki unworthy of serving Izumiko and belittles him every chance he gets. As the series progresses he begins to fall in love with Izumiko.

• Sōda Mayura (宗田 真響)
• Triplets older sister of Manatsu and Masumi. In the third episode she is introduced as Izumiko's cheerful and kind roommate. However, in episode four it is revealed that she is a mountain monk and is currently involved in a secret school-wide rivalry between herself and Ichijō. Although she seems kind, she at times can be just as calculating as Ichijō. After witnessing Izumiko's ability to identify Ichijō's spirit agents, she realizes that Izumiko and Miyuki might be more powerful than she thought. She decides to try and recruit Izumiko, and attacks Miyuki to reveal his true strength.

• Sōda Manatsu (宗田 真夏)
• Triplets younger brother of Mayura. One of Manatsu's defining characteristics is his intense love of horses. Especially his first horse, Tabi. He is usually very cheerful and kind, but when it comes to his family he can be very determined and fiercely protective just like Masumi.

• Sōda Masumi (宗田 真澄)
• Triplets younger brother of Mayura. He died of a heart defect while taking an afternoon nap when he was six. Masumi is very protective of his siblings and does his best to keep them safe when he can. Mayura and Manatsu are capable of summoning him as a divine spirit and communicate with him often. In his fight against Ichijō, it is clear he is very powerful and capable of devouring spirits. He has a very playful personality and sometimes likes to dress in girl's clothing much to chagrin of his identical brother Manatsu. However, when his family is threatened he can become serious and have a much darker personality.

• Sagara Yukimasa (相楽 雪政)
• The father of Miyuki, his sole intention is to protect the goddess. Despite being 33 years old, he looks quite young and lively. In some scenes in the anime it is shown that he is awfully strict and looks down upon Miyuki. He has a job as a model and is also a trained mountain monk.
