Meia

Meia is a mermaid living on Port Natalia. She longs for a hero to help her receive a Pledge of Marriage from the Kraken so that Meia and her older-than-appearance lover (she used charm magic to shrink his appearance into that of a child) can get married.

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

Luka soon learns of a request posted on a board in San Ilia. He heads back to Port Natalia, the origin of the request, and runs back to Meia. She explains her intentions of marrying her older-than-appearance lover and Luka agrees to help. She provides him a Written Pledge and a Ball of Guidance, the latter allowing him to enter the deep seas and Kraken’s domain.

If Luka succeeds on his journey, Meia gives Luka a blowjob and her entry is added into the Monsterpedia.

In Chapter 2, Luka requests her for the Guidance Orb once again. She gives it to him unconditionally as she has no further need of it.

Trivia
