Summary
Fou serves as the guardian deity for the Black Order's Asia Branch, a role established when she was sealed by Bak's great-grandfather. Though she is not human, she typically assumes a humanoid form to interact with others. Following Tyki Mikk's attack, Fou discovered Allen's body and transported him to the Asia Branch headquarters. She exhibits a tough-love attitude, especially toward Allen, relentlessly attacking him during training to force the activation of his left arm. When Allen is discouraged, she appears as other individuals, such as Lou Fa, allowing her to show a softer side without his knowledge. Despite a strong bond with Bak, which she often expresses through teasing, she is deeply protective. Fou can manipulate her form to transform her hands into axe-like weapons or mimic another person's appearance, and she communicates telepathically. She maintains a powerful barrier around the Asia Branch headquarters, acting as its entrance. Beneath her stern exterior lies a caring individual willing to sacrifice her life for those she loves. She assumed Allen's form to fight a level 3 Akuma, buying the real Allen time to escape. Before the battle, she whispered, "Bye bye, Bak." Although severely injured, she was shown recovering after Allen defeated the Akuma.
