Sins of the Sisters

Akira Fudo is just a normal kid in Tokyo, until an old friend of his, Ryo, shows up and turns his world upside down. An upcoming war of demons on humanity is waiting in the wings, however, the only way for a human to fight a demon is with their power. To save the world, Akira and Ryo risk a dangerous ceremony in an attempt to create humanity's only hope: the powerful Devilman.

It's the year of destiny, and 15 year old Kamui Shiro, a powerful psychic, has returned to Toyko after a 6 year absence, having left when he was very young. He wants to be with his childhood friends, Fuma (his best friend) and Kotori, Fuma's little sister (and Kamui's possible girlfriend). He wants to protect them from all dangers, but destiny and fate are haunting Kamui and pulling in himself and his beloved childhood friends. It is his destiny and his sole decision to decide the fate of the world, no matter if he wants the role or not. Now it is a matter of if he will join the side of the Seven Seals and become the Dragon of Heaven to save mankind or join the Seven Angels and become the Dragon of Earth to destroy all civilization so the earth can heal itself from man's destruction.

The "Academy Island Incident" in which four "kings" cross paths... Since then, Silver Clansmen Kuroh Yatogami and Neko have been searching for their master, Shiro. Without finding any clues to Shiro's whereabouts, the two became disheartened. However, one day, they see HOMRA members Rikio Kamamoto and Anna Kushina being chased by someone.

As the Overfiend slumbers, the mad emperor Caesar rises to power, enslaving a new race of demon beasts. Into this cruel existence is born the Lord of Chaos, the Overfiend's nemesis. As the blood-thirsty beasts capture the tyrant's daughter in a brutal coup, the Overfiend must awaken to an apocalyptic battle of the Gods.

Akira Fudo, adjusting to his new powers as Devilman, is in for a heap of trouble as his newest enemies sent from the demon world are Jinmen, the sadistic tortoise with his victims' faces on his shell --including Akira's mother-- and Sirene, the demon bird, who has more than a few tricks up her feathery sleeves to keep him and humanity at the brink of extinction.
