When Gowther's twin sister arrives at the Boar Hat tavern, she discovers the captain of the Seven Deadly Sins has decided they're meant to be together—whether she likes it or not.

Traveling with the legendary Seven Deadly Sins is chaotic enough, but for Hakusuku, a powerful shikigami, the real danger is entirely unnoticed: Captain Meliodas is secretly plotting to make her his wife.

Quiko, a quiet assassin, infiltrates the Boar Hat tavern to kill Gowther, the deadly sin of greed, only to find herself tangled in his surprising affection and her own unexpected sweetness.
