"Story of White" and "Story of Black", sounds pretty much equal to "Law" route and "Chaos" route here
As expected, this week we are introduced to the second protagonist, who is a siscon that gives the dark messiah vibes as well as his side of characters.
It is highly likely we can expect 2 completely unique routes (hopefully further divided into heroine routes absent in Corona) in the game + a true route as the game flow. Not a bad sign so far.
Looking for the past Eternal games, I guess one main character will have only 2 "main" heroines this time around, with the rest that can be H'ed as an added bonus.
I guess that is it for the introduction of the main cast, but given the SLG nature, I expect there are going to be alot more characters. The premise looks a lot more promising to Corona, now shall wait for the reveal of battle system...
