The 8th Sin (Male Reader X MLP EG X Seven Deadly Sins!)

Hi I'm (Y/N), and I work at the Bar Hat with my partner Meliodas, accompanied with our lovely waitresses, who serve the customers, and our "garbage disposal" known as Hawk, he's a talking piggy you see. Anyway, one day, the craziest thing happens! A girl, who was wearing a rusty armor comes in, and she is actually revealed to be Princess Elizabeth Liones! She's the youngest daughter of King Liones. She's come to find the Seven Deadly Sins to stop the Liones Holy Knights and their corrupt ways. And well, it turns out, there just happened to be an 8th secret sin. Just so you know, it turns out that Meliodas and I are two of them. Looks like it's time for a journey. We need to find the other Sins, and stop those corrupt Holy Knights!
