COSPLAY - Angel Beats!

Rinami is cosplaying as Yuri Nakamura from Angel Beats!. Angel Beats! is a 13-episode Japanese anime television series produced by P.A. Works and Aniplex and directed by Seiji Kishi. 

The story was originally conceived by Jun Maeda, who also wrote the screenplay and composed the music with the group Anant-Garde Eyes, with original character design by Na-Ga; both Maeda and Na-Ga are from the visual novel brand Key, who produced such titles as Kanon, Air, and Clannad. 

The anime aired in Japan between April 3 and June 26, 2010. Key worked in collaboration with ASCII Media Works' Dengeki G's Magazine to produce the project into a media franchise. Two manga series are serialized in Dengeki G's Magazine: one illustrated by Haruka Komowata, which began serialization in the December 2009 issue, and the other drawn by Yuriko Asami, which started in the May 2010 issue. 

A series of illustrated short stories written by Maeda and illustrated by GotoP were also serialized in Dengeki G's Magazine between the November 2009 and May 2010 issues. Two Internet radio shows were produced to promote Angel Beats!.
