Index: As usual, refer to the chapter title for actual chronological order.(i.e. Chapter 19 is actually Chapter 2, Side B, of Arc 1)
An extra/side story chapter with events that occured but wasn't in the timeframe of either of the A or B routes. (but close to it). They provide insight into other characters, so mc's wont be mentioned. Chapter 3A,3B,3C can be expected sometime within a week or two.
