Make a train station and demons can do a mission on it for EXP or Ranks or Items but it will trigger the event so Demon Slayers can come and stop it, gaining EXP or Ranks or Items.
Stuff that could come with this is:
Needs an upper moon rank to start
For slayers to take part needs a hashira rank
**If its not that very hard to get those ranks **
You can make a new demon blood art if Enmu isnt already added if he is already added make it so when the user is low can fuse with the train and have rapid healing (if slayers dont stop it)
xavvy_. You’ve Reached Level 1
