Cipher Hints from Episode 7
in Let us Brave episode 7, there is 1 cipher hint poster that actually doesn't use western earth letters... instead, there are DemonWorld Heroes letters on there... this has been done in episode 5 to but there were also a few Ceasarian Cipher text on there... the use of DemonWorld Heroes Cipher is actually done for 2 reasons in these 2 episodes...
 * 1) to make it harder to encode it
 * 2) because these 2 episodes are cross-over episodes that are linked with DemonWorld Heroes
