Is “INSERT CHARACTER OTHER THAN RICHARD” going to have a route or be dateable?
Side-characters and cameo characters (such as Bam, Azaghal, Carson, Dr. Tora,Reggie,Tai, Boulder or Grant) will never be dateable routes. I do not own those characters, and will not be putting funding towards having more art done of them. The primary focus is towards my main cast of characters.
