Witch Hunter Robin is a must see anime for fans of science fiction and fantasy. It follows the story of Robin Sena, who moves to Japan after being raised in Italy to join STN-J, a secret government group that hunts witches. Witches have powers that are inherited genetically and can lie dormant for many years before they "awaken." Members of STN-J often have their own powers and are trained to hunt witches. Robin's power of fire is particularly powerful.

The first half of the series follows Robin's integration into STN-J and various hunts, with each episode featuring a new witch. The latter half starts to delve into deeper questions of what makes a person a witch. As Robin learns more about the people she works for, she begins to question her own powers and alliances.

Witch Hunter Robin is a relatively short anime series. The art, especially the hunt scenes involving Robin's power, is visually stunning and fun to watch. The music and mood of the show is quite haunting and makes this a more serious anime. This is for older audiences and is generally recommended for people 13 years and older.
