As a secondary character, you are accepting that you may be needed in short bursts. With such a large cast of secondary characters, there may be bursts where you are important to the releases and needed frequently, as well as bursts where you are not needed for an extended period of time.

This Biyi Bird is a loyal and devoted fan of Lord Phoenix, and would spend even the last of his money on Phoenix merchandise. When it comes to Lord Phoenix, he does his best to be confident, showing his support and lifting Lord Phoenix's spirit when he finds himself at a low point.

Outside of being devoted to Lord Phoenix, Biyi is very clumsy being half of a bird, having improper balancing to carry things around (except his merch). He's also very doubtful of himself, shown with his sadness over believing he would be rejected by Lord Phoenix, and that he would never find his "true love" to merge with.
