Aku no Akuma

For 100 billion years shinjins (demigod)
fighting against akujins (demons),

Shinjins believe for akujins as evil race.
Therefore shinjins decided to execute them all,

But for 100 billion years always
akujins manage to protect
their planet and their self,

Until now descendant of
shinjins starting to attacked
again on akujins.
