Faith got lost, in the forest, when she came apon 7 trees, each has a strange symbol on it, her curiosity got the better of her, and she walks forward, suddenly there was a flash, and she suddenly woke up, at first this seems normal, until she realized, this wasn't her world, and that's how Hope found its way, into the Sin Dimension (You can choose to play as the 7 Sins, or Faith, I'll play the other)
