リィル・ナギ・アタランシア

The second princess of the underwater city Atalancia and Irionela's younger sister. Reserved and shy, but once she opens up, she approaches the other person without hesitation. She is physically weak, unable to do anything intensive. Her hobby is reading, and she regularly visits the castle's library. [Translated and edited from the official website] She's actually much older than she appears to be due to the effect of her royal blood, which is a mix of sea dweller- and land dweller-DNA, that makes them age more slowly and look more like human beings. Since her father is said to have come to the kingdom during a war (probably WW2) when his ship sank and passed away recently at the age of 100 while the game mentions smartphones, the game is set at least post 2007, making her at least 40 years old by the time the game takes place
