Meia

Meia is a mermaid living in Port Natalia, who appears in Monster Girl Quest. She is in a relationship with a human man, who she keeps in a child-like appearance to suit her tastes. She gives Luka a request to help her get married to her partner.

Chapter 1
When Luka arrives at Port Natalia, Meia tries to request his aid; however,, Lazarus’s attack interrupts them.

Meia's request ends up posted on a board in San Ilia, which is seen by Luka and causes him to head back to Port Natalia. Meia meets him and explains that she wants to marry her lover, which requires them to obtain a Pledge of Marriage from Kraken. However, they cannot go to the Southern Seas as her lover is too weak. She has been sending out requests for people to go on the journey for her since the law doesn't specifically say the couple has to send it. Luka agrees to help, and she provides him a Written Pledge and a Ball of Guidance, the latter allowing him to enter the deep seas and Kraken’s domain.

After Luka completes the request, Meia gives Luka a blowjob and her entry is added to the Monsterpedia.

Chapter 2
Luka asks Meia for the Ball of Guidance again. She gives it to him unconditionally as she has no further need of it.

Chapter 3
If Luka visits Meia in the aftermath, she mistakes Alice's child body, which is a result of Promestein sealing her true form earlier, as a result of her being shrunken by Luka, having agreed with her for turning their spouse young, though Luka tries to reassure her that it isn't like that.

Monsterpedia Entry
''“A young mermaid that lives in Port Natalia. Though mermaids used to tempt men into mating with them, they now live peacefully with humans in Port Natalia. With their diet being almost identical to a human's, their main reason to associate with humans is for reproduction. While most mermaids in Port Natalia have jobs and live in peace, there is some occasional trouble.''

''Easy-going, clumsy, and optimistic; Meia shares many of the common behaviors of her fellow mermaids. With the ability to manipulate water, Meia is fairly powerful even amongst her fellow mermaids. She uses her powerful magic to keep her spouse young. She separates chastity into mind and body. As long as her love remains for a single person, she doesn’t consider using her body a form of adultery.”''
