when are you use a different character i always on put their name of their character but it there is another character the butler i have to find which one it's good or bad password for that character i cant even figure out which one
If I remember peacekeeper is the password that give another bad end. More than the end where you choose no password. So have the password in that end that save the butler.
After that part have a some of routes you can go in bad ends. But I think none of these routes are finished. But them are long routes.
