Kazuki Oogami

Sōma's older brother and legal guardian, as well as priest of the temple of the Solar and Lunar Miko. His duties are to care for and maintain the legacy of the Miko, as well as to prepare them for battle. Calm and collected, he is especially worried about Sōma and both priestesses. Even still, there are some indicators that imply he's not telling everyone the full extent of what is going on. It is later revealed that he is Sōma's adoptive brother, as the real one is Tsubasa, the First Neck.
