Mika Furutsuki is a main character in the anime Uchū Shōnen Soran. She is the daughter of Dr. Furutsuki, an archaeologist, and lives with him at their home. When the protagonist Soran arrives on Earth after being raised on the high-gravity planet Soran and transformed into a cyborg, Mika and her father take him into their household. Mika becomes one of Soran’s closest human friends and a steadfast companion in his adventures.

She serves as the navigator of the team’s spacecraft, using her strong aptitude for science and technology to chart courses, operate equipment, and resolve technical issues. Mika is bright, curious, and always eager to learn more about the universe. She is kind-hearted and deeply loyal, often putting herself at risk to support Soran and their allies in battles against villains such as the psychic Mew group, the space demon Gorona, the superbrain computer Gaiver, and the pirate Gala. Her determination to succeed and her ability to remain calm under pressure make her a vital member of the group.

Mika’s primary motivation is to help Soran search for his long-lost sister and to protect the Earth from various threats. Over the course of the series, she demonstrates steady growth in confidence and technical skill. She maintains a close relationship with her father and works alongside him, and she also bonds with the flying squirrel-like alien Chappy, Soran’s companion. While Soran is the central hero, Mika’s contributions as a navigator, problem-solver, and loyal friend are essential to the team’s success.
