Yay more interests, welcome!

To answer the question. Humans dragged into this world, I have not read the light novels.

Manato's party may have a role in it, it might behappening around you all afterall.  However, you will equally have a role to change things should that happen. There may be mentions, but alot of things that may happen will be dependent on you all - including how far you want to go interacting with others.

I intend to be reactive about things so yes, this will not be a linear roleplay at all. It's a roleplay, you have more space to be creative here - that includes your roles and what you do. The only certain things that you must abide are, you're roleplaying a Human and you have no acute or exact memory of our world (occasionally your subconcious may make you say things like 'video' and things but you won't really know why or what a video is).
