A third view is based around a character called Inochi Ushina who isn't in the SSS, the character plays the role as someone who sees the Angel Beats! story from a third person perspective. Unlike everyone else he isn't one to believe in God, and has ‘regretted something he would never forgive himself for in his past life. The story basically goes through the whole Angel Beats! main story line in the background etc, as he tries to live his life like normal in that world.
