I see - thanks! Will definitely check out what there is so far sometime this week.
As for that chart - what's the meaning of the characters who have another little icon next to them?
I also recommend checking out From the Sin cross-linked here above. The grand remaster of that game goes public this coming Saturday and if you like this game, that game has similar themes as well.
You will see a similar chart there as well. (It's a sister game to SK.) The biggest difference is that the MC in SK is extraverted, whereas the MC in FtS is introverted.
