P.A. Works (Angel Beats!, RDG, Another and others) announced last year their new original work, Nagi no Asukara - a story about a boy and a girl and their high school romance. Beautiful art and animation seems to come as natural as breathing to P.A. and this fall's newest anime on the branch does not seem to disappoint in the slightest.
Ray (known for To Love-Ru - Trouble - Darkness) created the title song "Nagi", which is used in the video. With such a beautiful voice onboard as well as having Buriki (Haganai) in charge of the character design, we are in for an interesting treat for the coming season.
