Razette

ラゼット

A Noel mermaid who grew up alongside Castor. She currently sings and plays the organ at the church. Razette can also freely alter her face to resemble that of other people. If people consume her scales, it enables them to breathe underwater.
In the anime, she appears to fear Frau, as demonstrated when she cowers behind Teito after Frau greets her. This detail is absent from the manga. She also develops a fondness for Teito upon their first meeting. Additionally, she generally dislikes strangers.
