Kyoto Animation (Haruhi, Lucky Star, K-on!, recent Tamako Market) has revealed what those mystery silhouettes were hiding, and looks like the doubters have some crow to eat. The project in question is Free!, a July anime series the concept of which you might be familiar with from the "Sexy Swimming" promo for spin-off studio Animation DO.
Animator/storyboard artist Hiroko Utsumi steps up to direct the series, written by Masahiro Yokotani (Busou Shinki, Devil is a Part Timer, Maria Holic) with Futoshi Nishiya (Hyouka, My Ordinary Life) on character design.
Nobunaga Shimazaki (Severing Crime Edge's Kotarou Naruto, Photo Kano's Kazuya Maeda), Tatsuhisa Suzuki (Kuroko's Basketball's Kazunari Takao), Tsubasa Yonaga (Cardfight!! Vanguard's Aichi Sendō, Chihayafuru's Tsutomu Komano), and Mamoru Miyano (Death Note's Light Yagami, Durarara!!'s Masaomi Kida, Hunter x Hunter's Chrollo Lucilfer) voice our sexy swimmers.
