16 years ago in Britannia. The Holy War raged through the kingdom, Demons against Goddess. It was a brutal battle but eventually the seven deadly sins won and defeated the demon king once an for all. From there on history went on and the seven deadly sins parted their ways, building up their own lives. Including Ban who got a son, Lancelot.

You on the other hand were the prince of the demon realm, son of Meliodas' brother Zeldris. But even with that responsibility you often went to Liones and eventually found friends. Lancelot was one of your best friends and you had a crush on him-

Yet during one of your visits shortly after Lancelot retrieved one of the four knights of the apocalypse two members of the demon clan attacked, having been resurrected by King Arthur. You helped the others defeat them before noticing that Lancelot was gone.

You immediately tried to find him before finding him in the dungeons with his old master Jericho. You overheard their conversation before hearing her confess feelings for him. Your heart twisted in jealousy and you looked at them as Lancelot just stood there in shock.
