Tico of the Seven Seas (Japanese: 七つの海のティコ, Hepburn: Nanatsu no Umi no Tiko) is a Japanese anime television series by Nippon Animation. It is about an 11-year-old girl named Nanami Simpson and her best friend Tico, a female orca.

Unlike the other series in Nippon Animation's World Masterpiece Theater line, Tico of the Seven Seas is an entirely original story. A novelization of the series written by Akira Hiroo was eventually published in 3 volumes by Kadokawa Sneaker Bunko in conjunction with the broadcasting.[1]

An English dub of the series, entitled Tico & Friends, was produced by Ocean Studios. The dubbed series omits major character deaths and also edits out some violent, bloody and death scenes; one episode from the original version, which focuses on the aftermath of a major character death, is even omitted completely and replaced with a makeshift clip show episode (although some scenes from the omitted episode are included in the replacement).


Nanami Simpson is a young Japanese-American girl. Having lost her mother when she was young, she now lives with her marine biologist father, Scott Simpson, on board his research vessel, the Peperonchino. Scott has been in search of a creature known as the Luminous Whale, a whale that can glow brightly underwater, for many years and is determined to eventually see it and preserve its existence. Nanami also is close friends with an orca named Tico, who was rescued as a baby just before Nanami was born. The two have an unbreakable bond and swim with each other every day. As a result, Nanami gradually learns to hold her breath longer and swim deeper than other humans can.

Scott's search from the Luminous Whale soon puts him at odds with the Gaiatron Corporation, a greedy research conglomerate led by the ruthless and ambitious Adrienne Benex, who wishes to exploit the creature for a rare element it seemingly carries in its body. Aiding Benex are her right-hand man, Gaulois, and Dr. Charles LeConte, an old acquaintance of Scott's who is obsessed with the Luminous Whale.

Together, Nanami, Scott, and Tico, along with Scott's first-mate and right-hand man, Al Andretti, seek to locate the Luminous Whale before Benex and Gaiatron can. Over time, they are joined by a few new crew members:

As their journey goes on, the crew of Peperonchino encounter and make both new friends and enemies, and form bonds with each other, as they race against the corrupt Benex and Gaiatron to find the Luminous Whale first.



Nanami Simpson
Voiced by Megumi Hayashibara; Chantal Strand in the English dub
Nanami is the main protagonist in the series. At 11-years old, she claims all creatures from the sea are her friends. She has been friends with Tico ever since she was a baby, and has a close relationship with her father Scott, and friendships with all of their crew members throughout the series.
A killer whale who is a life-long friend to Nanami. In the Japanese version, she dies freeing Al's submersible from an iceberg crevice, which mortally injures her, and her body sinks to the depths of the sea, while Nanami looks on helplessly. In the last episode, "The Shining Circle" her spirit reunites with Nanami and her son via the Luminous Whale. In the English dub, she is still injured, but survives and the crew is forced to leave her behind to let her recover. She returns a few episodes later, shortly after her son Junior leaves the crew to join a super-pod of killer whales. In the final episode, the spirit that Tico reunites with turns out to be her own long-lost mother.
Junior is Tico's calf. In the Japanese original series, he takes Tico's place as Nanami's companion, along with her name, after the former sacrifices herself to save Al. He meets his mother again the series finale, "The Shining Circle". In the English dub, his mother survives, and is left behind to recover, returning not long after he leaves to join a super-pod of killer whales.
Scott Simpson
Voiced by Shuuichi Ikeda; David Kaye in the English dub
Nanami's father, who is a marine biologist, and captain of the Peperoncino. He has been searching for the Luminous Whale for seven years. He is a dedicated father to his daughter and is often the level-headed one for his crew. Scott is also very protective of his research of the Luminous Whale, refusing to let it or the creature itself fall into the wrong hands.
Alfonso "Al" Andretti
A fat Italian man who works with Scott, and always on the lookout for treasure. He is the chef and engineer of Peperoncino and often comes up with get-rich quick schemes in order to make the crew money. He serves as something of an uncle and mentor to Nanami and later to Thomas as well. A scene where he punches Professor LeConte in the stomach is removed.
Cheryl Christina Melville
Voiced by Venus Terzo in the English dub.
An English-American woman who comes from a wealthy family and craves adventure. She initially has a frosty relationship with the crew, particularly Nanami and Al (due to her joining the crew on a whim, and her initial reluctance to do any actual work), but they all soon warm up to her, and she ends up becoming a valued member and even something of a big sister to Nanami and Thomas. Due to her wealth, she often serves as the source for emergency funds when the crew needs them. Initially, she relies on her butler James to do the crew work for her, but later starts contributing by herself following his brief departure from the crew in the seventh episode, and becomes more independent as a result.
James McIntyre
Voiced by David Kaye in the English dub
Cheryl's loyal butler. Born near the Cliffs of Dover, he has served the Melville family faithfully for many years, and is charged with looking after Cheryl while she attends college in New York. James joins the crew of the Peperoncino at the same time as Cheryl, but leaves in the seventh episode and joins the crew of the Gaiatron ship Scorpio, after switching places with Thomas LeConte. He returns to the Peperoncino ten episodes later, and remains with the crew up to the series finale.
Thomas LeConte
A boy the Peperoncino crew met in the Bahamas and the son of scientist Dr. Charles LeConte. Intelligent and computer-savvy, but also introverted, lonely, and somewhat cautious, he craves attention from his father, but is often pushed aside and neglected due to Dr. LeConte's research regarding the Luminous Whale. In his first appearance in the second episode, he cons Nanami and Al in helping him return to his ship in return for a treasure map that turns out to be fake. Several episodes later, the crew meets him again on his father's ship, and after being rescued after getting trapped underwater in the Peperoncino's mini-sub, he decides to join their crew to go out into the world and become more extroverted, becoming Al's unofficial apprentice and Nanami's closest human friend. By the end of the series, he manages to patch things up with his father.

A scientist who is an old acquaintance of Scott Simpson, and Thomas's father. Obsessed with the Luminous Whale, LeConte's determination to find it causes him to ally himself with the corrupt Gaiatron Corporation, and neglect his son.
