This is one of the series to which I've been looking forward to the most this season, so I can't wait for it to start, myself.
OP theme:
Summer rain by
Kobukuro (their first ever anime theme)
ED theme:
Koikogare te Mita Yume by
Ayaka (her only previous anime theme song was for Doraemon: Nobita and the Green Giant Legend)
This is one of the few anime produced by Warner Music Japan, which is why we're seeing Kobukuro and Ayaka, their two top tier artists, performing on Cross Game. I can't wait to see one of Kobukuro's songs in animated form.
