Sing “Yesterday” For Me will feature a new opening theme song starting with its seventh episode, reports the series’ official Twitter account.
The song, called “Aoibashi,” will be performed by Sayuri. Sayuri, who made her major-label debut in 2015, is well-known by many anime fans: she’s performed songs for Golden Kamuy, Scum’s Wish and My Hero Academia.
Multiple theme songs are unusual for such a short show, but this isn’t the only innovative thing Sing “Yesterday” For Me trying: it’s set for 18 episodes, but only 12 of those are airing on Japanese TV. The final six are exclusive to streaming site AbemaTV.
In the US, Sing “Yesterday” For Me is streaming on Crunchyroll, which ostensibly will carry all 18 episodes. Here’s how the Crunch describes the show:
Kei Toume‘s eighteen-year youth ensemble classic gets its long-awaited animated adaptation. A story of love and humanity, following four boys and girls trying to live their best lives through hardship and turmoil, in a small town on a private rail line just outside of Shinjuku. Minor misunderstandings lead to big complications, and their various feelings become entangled. A story of daily life lived 49% looking back, 51% looking forward.
