In Ocean Waves, what is the name of the male protagonist?

In Ocean Waves, the male protagonist is Taku Morisaki.

Taku is a high-school student in Kōchi whose memories frame the film's coming-of-age story. He becomes involved in an uneasy love triangle with his close friend Yutaka Matsuno and Rikako Muto, a talented but difficult transfer student from Tokyo.

The plot follows Taku as he tries to understand Rikako's behavior, including an episode in which she borrows ¥60,000 from him during a school trip to Hawaii.

Ocean Waves was first broadcast on Nippon TV on May 5, 1993, and was directed by Tomomi Mochizuki, making it the first Studio Ghibli production directed by someone other than Hayao Miyazaki or Isao Takahata.
