All character routes of Bewitching sinners. All of them will be involved in the main story and 2 will be the only way to get to a certain witch but other than that you can choose whichever character you like. There won't be stat raising but I will have trait raising instead using quest as a guideline similar to Lingering to help pace the story such as in Lingering there is underlying quests such as Lock finding out Xander's secret or Angel and Goldie bonding so she can have the better ending.
Overall Bewitching Sinners should be more coherent than Cupid as in Cupid it was pure romance which became repetitive when in their relationships route but with Bewitching Sinner you bond due to trauma //slap ehem I mean due to story events which should make them more fleshed out.
