Miuna Shiodome is a girl of mixed sea and land heritage who lost her mother at a young age, causing her to initially resist her stepmother out of fear of experiencing loss once more. As the story unfolds, she steps into the spotlight and awakens the rare ability known as 'Ena,' granting her the power to breathe underwater. Carrying a deep, unwavering love for Hikari Sakishima across the years, she transforms from a timid and withdrawn girl into a figure of quiet strength and maturity. In the end, she willingly embraces the burden of the Sea Maiden, choosing self-sacrifice to protect those she holds dear.
