At the end of the 21st century, the discovery of a new energy source called "DG energy" (short for "divine grace energy") has revolutionized Earth's economy and allowed humanity to colonize space. However, when the initial expedition reaches Pluto, they are attacked by a mysterious, giant life-form known as "Nergal." The Earth Alliance Army fights back by creating an "AG Unit" using ancient robot weapons known as the "G's Frame" which were excavated from archaeological sites all around the world. Girls with special qualities known as "Ancient Girls" can pilot these robots against the Nergal. However, the first AG Unit suffers heavy casualties in the Jupiter Trojan campaign, and the pilot of Unit 04, Minamiya Reiu, goes missing-in-action... Years later, Minamiya Reika, the younger sister of Reiu, enlists with the AG Unit to search for her sister and to protect the Earth from the Nergal. A story of friendship, ancient robot weapons, and battles to the death with the Nergal ensues. (Source: Crunchyroll News)

During Koyomi Araragi's second year at Naoetsu Private High School, he has a chance encounter with Tsubasa Hanekawa, the top honor student in his class. When they strike up a conversation, Hanekawa mentions a shocking rumor: a vampire with beautiful blonde hair and freezing cold eyes has been seen lurking around town. Happy to have made a new friend, Araragi writes off the rumor and goes about the rest of his evening in a carefree manner. However, on his way home, he stumbles across splatters of blood leading down the stairs to the subway.
