Akeno Shiranui

Akeno is not only a mermaid but also a quotmermaid examinerquot. She has the responsibility of deporting all the merpeople who fail to qualify as not only resembling humans but also not arousing any suspicion of their true identities. When first introduced she had a hostile attitude towards the other major protagonists. This later changes as develops feelings of compassion towards them and also as she finds her quotdutyquot as a Knightintraining as an excuse used by the final antagonist.
