The latest Idol Master property looks to be a baseball anime set during the Taisho period, in which team 765 valiantly rise to the challenge laid down by a rival team…
The above image may be a Photoshop poking fun at the uncanny resemblance, but the resemblance itself is real enough, as you can see on their official site.
The anime in question is 大正野球娘 / Taisho Yakyuu Musume (Taisho Baseball Girls), an anime adaptation of a novel surprisingly featuring the antics of a group of baseball playing schoolgirls in the Taisho period (1912-1926 – in practice this means longer skirts and more kimono). The title is set to air in 2009.
Be assured that this has nothing to do with Idol Master, as far as anyone can tell.
The reason for the rather pronounced resemblance to Idol Master must surely be coincidence, must it not?
