Description
Fei Zhui Lau is a character who appears in the anime Sacred Seven: Shirogane no Tsubasa. Fei was one of many individuals who were taken to a laboratory run by the scientist Kenmi, where cruel experiments were conducted to research the effects of the Sacred Seven crystals on human subjects. Fei is the younger brother of Hon, also known as Hongyu Liu, another test subject in the same facility. After witnessing Hon transform into a Darkstone and believing him to be dead, Fei was rescued by another experiment survivor, Knight Kijima, and the two escaped together. Following their escape, Fei and Knight lived in hiding, seeking both their freedom and a way to get revenge on those who had experimented on them.
Fei has a youthful appearance, with shoulder-length golden blond hair and green eyes, and is seldom seen without a green scarf. Fei's age is not explicitly stated, but based on his size, it is estimated he could be as young as eleven or twelve, yet is older than seventeen. Although Fei has a feminine appearance and sometimes prefers to wear female clothing, the character was confirmed by the creator to be male. In the Shirogane no Tsubasa Picture Drama, Fei and Knight even appear at Ruri's school in uniforms, with Fei wearing a skirt, which continues to cause other characters to wonder about Fei's true gender.
Fei's personality is defined by a deep and selfless care for those who have earned trust. This is demonstrated when Fei runs across a dangerous fight between Hon and Knight to deliver a vital serum, and when offering to help after Ruri is taken by Kenmi. Fei dislikes feeling helpless or inactive. A strong sense of responsibility also drives the character, as Fei later blames himself for the tragic events that unfold.
Fei was originally a Lightstone, a type of human who can control their Sacred Seven powers. However, Fei possesses a unique and unstable trait that an unknown trigger can cause a transformation into a Darkstone, a more dangerous form where power overcomes the individual. Fei's Lightstone abilities are defensive in nature, similar to those of Ruri Aiba, though Fei admits to being not pure enough to be as powerful as her. One of Fei's most critical abilities is the power to produce a serum from blood. This serum is necessary to force Knight Kijima back into his human form when his own Darkstone powers threaten to consume him.
Fei's closest and most important relationship is with Knight Kijima. The two share a powerful bond forged through their shared suffering and escape from Kenmi's laboratory. Fei acts as Knight's medic, and their care for each other is mutual, with Knight having looked out for Fei since Hon disappeared. Their relationship is further highlighted in the story of Shirogane no Tsubasa, which follows their perspective as fugitives. Fei also develops a relationship with Ruri Aiba. Initially distrustful, Fei comes to care for her, even risking safety to save her. After the final battle, Fei and Knight visit Ruri's school specifically to apologize for having hurt her in the past.
Fei's personal development is driven by a tragic family history. Despite witnessing Hon's initial transformation into a Darkstone, Fei never gives up hope of finding a way to save him and restore his humanity. The story takes a dark turn when Hon is killed by Kenmi and Knight is defeated. Consumed by grief and guilt, believing everything that happened was fault, Fei's Lightstone becomes corrupted by Darkstone energy, transforming into a monstrous, frog-like Darkstone form. In this state, Fei can fire projectile crystals from the eyes. Kenmi notes that Fei's powers, even as a Darkstone, remain defense-focused, which he can then absorb to give his own suit greater defensive capabilities. Ultimately, Fei is rescued from this corrupted state with the help of Alma Tandouji and Knight, who gain the power of a Lightstone to save Fei from the darkness. After being saved, Fei is last seen with Knight, finally at peace.
