Wakasa is one of the main characters in the series. He is a mysterious merman with long blond hair. His real age is unknown.
Wakasa is incredibly attractive, with stunning blond hair and striking blue eyes. Though beautiful, he has a selfish and shameless personality. He often acts spoiled and does whatever he pleases, without much thought for others.
Being a merman, Wakasa rarely leaves the bathtub. His favorite food is hamburger steak. He was originally living upstream near a dam, but rumors started about a “half-fish man” being spotted in the area. Feeling uncomfortable, he moved into Tatsumi’s bath instead.
After seeing how dirty the river was, Wakasa developed a strong dislike for green-colored water.
Wakasa is the charming, quirky merman who brings chaos and laughter to Tatsumi’s daily life. His beauty, boldness, and love for baths make him a truly unforgettable houseguest!
