Not a real need of 1 year in RMDW, you can be half assed and leave right after it starts xD. Or make yourself some kind of connection that helped you enter the IK and enter the RMDW right off the bat. :P Or cause some ruckus with your ability and discover the thing accidentally (Thanks to SD), you joined because you feared for your life, after a year, you quit. Something of the sorts if you want your character to have 16.
