Seven Mortal Sins

Sin Seven Mortal Sins is an original action-fantasy TV anime produced by TNK, boldly blending ecchi elements with dark, mythological spectacle. Directed and series-composed by Yoshimoto Kinji, this ホビージャパン-originated project plunges viewers into a fierce power struggle across Hell and Earth. Iconic demon lords—Lucifer, Leviathan, Mammon, Satan, Asmodeus, Astaroth, Belphegor, and Beelzebub—each embody one of the seven deadly sins, clashing in breathtaking battles while the fate of human girl Maria Totsuka hangs in the balance. With striking character designs and relentless action, Seven Mortal Sins delivers a sinfully entertaining ride for fans of dark fantasy and ecchi anime.

Set in a world where the divine and the infernal collide, this dark fantasy follows Lucifer, a proud and powerful archangel who defies the will of God and is cast down from the heavens, condemned to fall into the depths of hell. During her descent, fate brings her into an unexpected encounter with Maria Totsuka, an ordinary high school girl living on Earth. Upon arriving in hell, Lucifer crosses paths with Leviathan, a demon who introduces her to the grim hierarchy that governs the underworld — the Seven Deadly Sins, a group of immensely powerful demon kings who reign over hell's many domains. Stripped of her former glory and now navigating a realm completely foreign to her, Lucifer must find her footing alongside her unlikely companions. What kind of journey awaits a fallen angel, a human girl, and a demon in a world ruled by overwhelming power?
