Akira’s Family Bonding Ritual Summons Ancient Goddess Inana’s Contract
Akira’s father, an archaeologist, remarries and leaves him with his new stepmother, Yukie, and three stepsisters—Yuki, Nana, and Miu—while he stays abroad for a discovery. After secretly sharing a moment with Yukie, Akira finds a mysterious box containing a Sumerian scroll and three bottles. Reading the scroll, he learns he’s contracted by the goddess Inana to collect the love essence of his sisters before the next full moon, or face dire consequences.
