Nanatsu no Taizai - Kamigami no Gekirin - Episode 12 - Elizabeth Heals

Elizabeth, as a Goddess Clan member, does what she used to do best — healing anyone who needs it.

Melascula really wanted to make life difficult for Ban and Elaine. Everyone thought that to defeat her, they would have to kill her, ending Elaine's temporary life at the same time. Elizabeth decided on the best route by neutralizing Melascula's decaying power accrued over millennia and returning her to her original demon form of a small poisonous snake.
