Seven Mortal Sins (Season 1)

Seven Mortal Sins (sin 七つの大罪, 2017) is a Japanese dark fantasy anime you can watch online on iFILM. Director Kinji Yoshimoto takes a well-worn theological premise and flips its most basic assumption: Lucifer is a fallen angel — and she is female, cast out of heaven for her pride.

On her descent she crosses paths with Maria, a high school student on Earth who offers her help. The two arrive in hell together and find it ruled by seven demon queens, each embodying one of the deadly sins, who immediately seal Lucifer's powers. Getting them back means going through every one. Eri Kitamura, Akane Fujita, Ai Kakuma, and Yoko Hikasa lead the voice cast.

The series leans into its adult content and provocative visual style. What lifts it past the obvious is the theological angle — it is genuinely interested in reframing who the sinner is and why. Stream Seven Mortal Sins (2017) online on iFILM.
