A Stolen Heart -- Having successfully passed Gloxinia and Drole's special training, King and Diane return from the past, where they learned a dark truth about their fellow comrade, Gowther. Back in the present with their memories intact, Diane and King reunite with the rest of The Seven Deadly Sins—and come face-to-face with Gowther! Diane swears she'll help Gowther reclaim the heart he lost, but when Gowther would rather erase his memories than relive his painful past, it may be a task easier said than done…
