With a new promo teased over the weekend for Free! Eternal Summer, the official site has updated a touch on the new character that was given a little bit of time in it. Named Sosuke, the character will be played by Yoshimasa Hosoya. According to the translation via ANN, Yamazaki is one of Rin’s best friends from elementary school who understands him well. He has a strong personality, and never gets irritated by anything. He takes a dry and harsh position on swimming toward himself and those around him.
The show is set for a summer broadcast in Japan on the usual stations and it’s expected that like the first season that it will get a simulcast release here as well through Crunchyroll. The first season has not been licensed for home video release by any distributors outside of Japan.
Plot concept: Nanase Haruka loved to be in the water – loved swimming. In elementary school, Nanase Haruka, Tachibana Makoto, Matsuoka Rin, and Hazuki Nagisa attended the same swimming class together. Time passed, and as Haruka was living an uneventful high school life, he suddenly encountered Rin again. Rin challenged Haruka to a race and showed him how much stronger he had become. Soon enough, Makoto and Nagisa also rejoined the group, and along with a new classmate, Ryugazaki Rei, they established the Iwatobi High School Swimming Club.
