Nanatsu no Taizai OVA

Long before Ban became the Fox's Sin of Greed, his search for immortality led him to the Fairy King's Forest and its Fountain of Youth. There he met Elaine, the guardian who initially distrusted the human intruder. As the two spent time together, hostility slowly became affection, until a catastrophe forced Ban to confront what he was truly willing to lose for the person he loved.

Elsewhere, the Seven Deadly Sins reveal lighter pieces of their lives between battles. Brief encounters, jokes, and personal moments show the unusual bonds holding the group together when they are not fighting enemies powerful enough to threaten the kingdom.
