Buffy the Vampire Slayer:Ring of Fire

It is 1997, the darkest period in Buffy Summers' young life -- a time when the man she loves becomes a monster she must destroy. Buffy's lover, Angel, has again lost his soul and re-emerged as the murderous Angelus, a vampire feared throughout Europe for decades. Thirsting for power and for the blood of the Slayer (that's Buffy!), Angelus steals a suit of ancient Japanese armor in order to summon up the demon that once inhabited it -- a demon who can bring Angelus ultimate power and eliminate the Slayer once and for all!
