Several years prior before the beginning of the series, Kaito had met a young beatiful mermaid. One night, the mermaid went above to the surface world where she came across a cruise ship and began to sing. Kaito heard her singing and followed the sound of her voice and soon spotted her, causing him to discover the existence of mermaids. However, a huge wave had suddenly appeared and crashed into the cruise ship, causing it to sink into the ocean and Kaito to fall into the sea. The mermaid had quickly rescued him and brought him back to shore, but Kaito had still not regained consciousness. In order to save his life, the mermaid gave him her pink pearl and Kaito had awaken, thus saving his life. Ever since, Kaito has been in love with the mermaid who saved him and never forgotten her, always keeping her pink pearl inside the pendent he wears around his neck as a reminder and good luck charm. Eventually, several years later, Kaito met a new girl named Lucia Nanami, but unknown to Kaito, Lucia is actually the mermaid who saved him as a child and has returned to the surface world so that she may find and retrieve her pink pearl. Originally when they were reunited, while Kaito had slight suspicions, he ultimately failed to recongize Lucia as the mermaid who saved him. While Lucia had her suspicions, seeing the resemblance between Kaito and the young boy, she refused to believe Kaito was the same boy due to his teasing and flirtatous personality. However, Lucia had found herself soon developing feelings towards him and eventually during an attack by one of the members of the Dark Lovers when Kaito was captured, Lucia realized he was the same boy she rescued. Kaito returned Lucia's pearl, causing her to transform into her idol form for the first time and save Kaito. Upon returning to the surface, Lucia and Kaito shared a heartfelt and proper reunion on the beach and they embraced each other.
Since first meeting Lucia, Kaito has found himself falling in love with her, but while he constantly denies his feelings towards her, he has been shown to be jealous of other guys around Lucia on several occasions more specifically Sakiya, the Western Japanese Surf Champion. Kaito is also known to playfully tease Lucia for fun, but sometimes Kaito fails to realize how hurtful his words can actually be towards her such as when Lucia asked Kaito if she wasn't around anymore, Kaito replied it would be peaceful and quiet, much to Lucia's sadness. However, Kaito does learn to realize when he has upset Lucia as he becomes distracted and lost in thought, making him regret his actions. Lucia constantly tries to express her feelings for Kaito and always tries to create romantic settings for them to become more closer. Although they don't always go according to Lucia's plan, it would somehow work out in the end as Lucia and Kaito do become more closer and their love growing more stronger. Lucia and Kaito's relationship gradually grows more stronger and closer throughout the series. Since first reuniting with Kaito and seeing his passion and love of surfing, Lucia begins to watch Kaito whenever he surfs and also begins to make bentos for him. While Kaito pretends act aloof, he is secretly happy Lucia watches him and comes to really enjoy her bentos that she makes and enjoys spending time with her.
It's also shown on several occasions thoughout the series that Kaito possess a strange and incredibly strong power. An unknown symbol appears on Kaito's forehead and it activates whenever Kaito witnesses Lucia in danger and the power activates so that Kaito can protect Lucia from what ever tries to harm her. Kaito's power proves that he isn't really human and that Kaito sees Lucia as his most important person as she is the only person who can activate his power. Kaito's protectiveness of Lucia has been shown and proven numerous times throughout the series, even when his power isn't activated he becomes concerned about Lucia when she isn't around and goes to great lengths to find her and make sure she is alright. Kaito is also shown to become really upset and depressed when Lucia isn't around and during these times it causes him to make him further realize how he truly feels about her and make him realize how truly important she is to him.
While Kaito and Lucia are not officially together, they have shared several romantic kisses, during some of their most intense romantic moments together that further strengthens their relationship. While most of the kisses have occurred when Lucia is in her mermaid form, there have been other situations due to other circumstances such as when Kaito and Lucia were possessed by the spirits of two lost lovers of when Kaito was conflicted with his feelings regarding the mermaid from his past and Lucia, eventually resulting in a two-person love triangle. The true challenge and turmoil to their relationship that occasional causes it to become somewhat complicated and strained is Kaito's conflicting feelings as well as inability to realize that Lucia and the Mermaid who saved him are the same person. Kaito believes himself to be in a love triangle as he can't decide who he truly loves more.
Throughout the first season, Kaito remains completely oblivious that the mermaid and Lucia are one and the same person, but Lucia constantly tries to make Kaito realize the truth on his own as Lucia can't directly tell him otherwise according to an old mermaid legend she would turn into sea foam. On several occasions, Kaito has discovered/believed that Lucia and the mermaid are the same person, but either loses his memories or brushes the possibilities aside, believing them to be his imagination or a dream. Lucia becomes upset during these situations as she believes Kaito doesn't fully love her as he only cares apart of her. Lucia also comes to believe that Kaito will only love the mermaid side to herself and will never truly love her the way she is and will only ever love her mermaid form.
Eventually, Kaito had to make a descison between Lucia and "the mermaid", but still hadn't made his decision. However, during a heavy snow storm, Lucia went missing as Kaito was leaving for a ski trip and she tried to deliver a bento she made him but got lost in the blizzard. The trip was cancelled and Kaito returned only to discovered, Lucia was missing and set out to find her. Kaito eventually managed to find Lucia due to the power of pearl and made a snow igloo as shelter from the storm. During this time, it finally made Kaito realize how important Lucia was to him, thus finally making his decision of who he really loved. However, Kaito still hadn't made his feelings clear to Lucia and instead somewhat made Lucia uncomfortable as she believed he still loved her mermaid form than her actual self.
Later, Lucia had sadly discovered that Kaito would be leaving to attend a surfing school in Hawaii. Kaito had discovered from his aunt that he isn't the biological child of his parents, discovering he is adopted. In order to learn more about himself, Kaito decided to leave and attend Hawaii. Lucia decided in one last attempt to finally and properly express to Kaito her true feelings by giving him a Valentine's Day chocolate while learning if Kaito really loves her more than "the mermaid". Lucia nearly didn't succeed as she was convinced that Kaito will only ever love her mermaid form and will settle if he doesn't truly love her. However, to Lucia's happiness, Kaito had revealed that he truly cares and loves her more than "the mermaid". Kaito finally admits his love for Lucia and gives her a ring to symbolise his love and promises he will return once he discovers his true self. Lucia promises to wait for Kaito and Lucia and Kaito finally and officially become a couple and share their first real proper kiss as they embrace their newly formed relationship.
Shortly after Kaito leaves and goes to Hawaii, he and Lucia begin a long distance relationship. However, Kaito is taken by his twin brother, Gaito who wants to combine his and Kaito's powers to destroy the land and sea. Lucia along with the rest of the Mermaid Princesses discover the news and while fighting Gaito, rescue Kaito. During this time, Kaito finally at long last realizes that Lucia and the mermaid are the same person. Kaito apologizes to Lucia for not realizing the truth, finally realizing how much suffering he has caused her due to his obliviousness. However, Lucia is filled with tears of joy, knowing someday Kaito would find her and at long last, Kaito and Lucia have a true offical romantic relationship together with no secrets and can finally have a real future.
