Rei Suzumura continues to hunt Horrors in a certain city. One day, he meets a young woman in love with photography, Alice Hiromi. After witnessing Makai Knight ZERO in action, she develops an interest in Rei. Meanwhile, a carriage crosses a far away bridge. The carriage contains a coffin in which a man lies. That man is none other than the Dragon Knight, who used the power of Dragons to hunt Horrors.
Rei Suzumura, Zero the Silver Fanged Knight, is patrolling on his own when he encounters the white Horror Ring, who has created a commune where Horrors and humans live together in harmony, so long as one human a month allows themselves to be devoured by the Horrors. Rei, along with Makai Priest Cain and the knight-in-training Yuna are ordered by the Makai Senate to slay Ring and free the humans under his thrall by means of Yuna's mother the Makai Priestess Iyu.
