Wanna explore further than what this site can offer? Take a look here!

Learn all about the extensive story, characters, and history of The Mark Side here. It is planned to have most of the information from the wiki hosted on this site at some point, but for now, Fandom is your best bet if you want to learn more about the lore!

Some information here may be outdated to the current series.

Interactive content! Ask questions to The Mark Side characters and see what their response will be. Expect animated short videos soon!

The specific events and actions depicted are noncanon to the main series, and should be taken loosely.

A loosely canon spinoff / continuation of The Mark Side after the events of The Bad Ending. Currently it is not being focused on as heavily as the main series is, but content for it will be released sporadically.

Contains demons and lots of angst! Not a part of the main series, as it is less grounded in reality.
