The Odd Sins

Prologue

In a bar, The Boar Hat, a yellow haired male was serving customers, their orders. The food here is not the best, but the alcohol is. Everytime a meal was given, and no one ate it, a pig ate it.
People were talking about the legendary Seven Deadly Sins, and the mythical Demon Sins, although these sins worked together, apparently no one believes in them, except the sins themselves.
Suddenly, there was the sound of metal clanking together outside the door, a suit of rusty metal armour came through the door, causing everyone one to leave.
The male jumped over the bar, asking the amoured person. The person just fell on their back, the helmet falling off, showing a young woman with silverish white hair. The pig, and the man tended to their visitors needs until she woke up.
The male groped her chest, making her eyes shoot open, and sit up quickly. "Your heartbeat is good!" The male said, giving a thumbs up. The female thanked him, and asked how she got there. He explained it, and offered her a meal.
She gladly accepted the offer, and he fixed her a meal. After tasting it, "How is it? Horrible right?" The young man asked, making the girl nod. Then, a tear streamed down her face, stating that it was still good, making the male, and pig shocked.
Knock! Knock!
"Open the door! We know You're in there, Rusty Knight! One of the Seven Deadly Sins!!" The female was obviously scared. They came up with a plan. The girl tried sneaking through the back, but was discovered, and chased through the woods, the male saved her, and so did the pig.
-Time skip-
The girl, now known as Princess Elizabeth, found out the man is one of the Sins, their captain, Meliodas.
