EXO, once the world's most famous crime-fighting group, with twelve members, based in South Korea and China. Their biggest rival was B.A.P., which stands for "Black As Poison". And as in all stories of heroics, EXO always defeated them.

Until now.

B.A.P. found EXO's weakness. The moon is the source of all of EXO's special powers, powers that no other human has. Their powers are strongest on dats of solar eclipses.

But that's also when they're at their weakest.

B.A.P. discovered this, and constructed a machine that could emit radio waves that were meant to disrupt the connection between the moon and all twelve members of EXO, but it could only be done during a solar eclipse.

So that's what they did. With the use of radio waves, the signal was spread all over the Asian continent, and on that day, EXO vanished. Each member's memory was erased, and they were put back into the population as regular citizens with no idea of their pasts. They could even walk by each other on the streets and regard each other as total strangers.

B.A.P. siezed their chance and took over the once peaceful land once kept that way by EXO.
