Description
Fei Zhui Lau is a young individual of unknown specific age, though their small stature suggests they could be as young as eleven or twelve, but likely older than seventeen. They have shoulder-length golden blond hair and green eyes, and are almost always seen wearing a distinctive green scarf. While Fei has a feminine appearance and often wears female clothing, the character has been confirmed as male. Their name, following a three-syllable structure, suggests possible Chinese or Hong Kong origins based on its Cantonese pronunciation.
Fei is a Lightstone, which is a type of Sacred Seven bearer who can maintain control over their powers, similar to Ruri Aiba. However, Fei possesses a unique and dangerous trait: an unknown trigger can cause their abilities to become unstable, transforming them into a Darkstone. This instability may be the reason why they were originally placed under observation in Doctor Kenmi's laboratory. As a Lightstone, Fei possesses the ability to create vaccines using their own blood. This serum is crucial as it forces those who have transformed into Darkstones back into their human forms. Fei tried to produce more of this vaccine for Knight Kijima but found it impossible because their own blood was not pure enough, indicating that their abilities as a Lightstone are not as strong as Ruri's.
Fei's personality is defined by deep loyalty and selflessness. They care profoundly for those who have earned their trust, particularly Knight Kijima. Fei is not one to remain passive, as shown when they bravely ran across a battlefield between Hon and Knight just to deliver a vital serum. Fei is generally cautious around new people, initially distrusting Ruri Aiba, but over time this distrust gave way to genuine care, even leading Fei to offer help when Ruri was captured. Fei has shown a strong sense of responsibility for past events, which can become overwhelming. When they felt that everything that happened was their fault, Fei wanted to destroy everything, but was eventually brought back to normal with the help of Alma and Knight.
Fei's backstory is tragic. Like Knight and their brother Hon, Fei was a test subject in Kenmi's laboratory. Fei and Knight were experimented on, and when Knight finally managed to escape, he took Fei with him. Hon was left behind after he transformed into a Darkstone, with Knight believing him to be dead. For years after their escape, Fei and Knight lived secretly, seeking both their freedom and revenge against Kenmi. Fei's brother, Hon (also known as Hongyu Liu or Zero), also carried Sacred Seven powers, but after a fit of rage transformed into a Darkstone and could not return to human form. Fei held onto the hope of freeing their brother from this state.
Fei's relationship with Knight Kijima is the most significant in their life. Fei acts as Knight's medic, providing the serum needed to keep his Darkstone transformations under control. They are extremely close, having spent a long time together in the laboratory before escaping. Knight looks out for Fei, and Fei remains fiercely loyal to him, always staying by his side and supporting him. This bond is mutual; Knight cares greatly for Fei and has gone to great lengths to save them. Fei's relationship with Ruri Aiba evolves throughout the story. Initially untrusting, Fei eventually comes to see Ruri as an ally, even saving her on one occasion. After the final battle, Fei and Knight visited Ruri at her school to apologize for having kidnapped her earlier.
Throughout the story, Fei serves as a necessary support for Knight. While Fei's blood is meant to create a drug that forces Knight back to human form when his Darkstone side threatens to take over, the reality is that Fei ultimately cannot create this medicine. This forces Fei and Knight to return to Kenmi to steal the drug, showing Fei's determination to save their partner no matter the risk. When Fei's brother Hon was killed by Kenmi and Knight was severely beaten, Fei's Lightstone became corrupted by Darkstone energy. In this Darkstone form, Fei transforms into a frog-like creature capable of firing projectile crystals from their eyes. Kenmi noted that Fei's powers, even as a Darkstone, are like Ruri's and are more focused on defense rather than offense. Fei's abilities can also be absorbed by others, as Kenmi was able to take Fei's defensive golden projectiles and grant defensive capabilities to his own suit. Eventually, Fei was saved from this corrupted state by the combined efforts of Alma and Knight. Following these events, Fei and Knight appeared together in a school setting, wearing uniforms and visiting Ruri to make amends, showing a return to stability and the possibility of a more normal life.
