Angel Beats! - S01

Death is one of the many mysteries that has kept humanity in the dark since the dawn of time. But the burning question of what happens to the soul after death is soon answered for 17-year-old Yuzuru Otonashi. He wakes up with no memories in a dimension between life and death, and discovers the unsettling truth of the afterlife. Taking the form of a high school, this strange dimension exists to shelter those who died unwanted deaths. Feeling wronged by God during their lives on earth, the school's residents have decided to form the Afterlife Battlefront, a rebellious faction determined to oppose their god-like student council president, Kanade "Angel" Tachibana. The group's leader, Yuri Nakamura, recruits Otonashi into their fight against Angel so they can take control of their own lives. But questioning the morality of their actions, Otonashi steps behind enemy lines to understand the other side of their shared fate.
