Daemons of the Shadow Realm | GOGOAnime

Synopsis:

In a remote village lived two sets of twins, separated by day and night. Years later, with her older brother, Zoro, now a monster hunter, her sister Asha was imprisoned, assigned to a special mission that forbade her from meeting with the nobility.

On a blind date, a group of armed men in helicopters, called “birds” by the locals, attacked the village in search of Euro, killing every adult in their path. When Zoro tries to find Asha and escape, he finds her dead; to make matters worse, her killer is her twin sister.

Before she can bear it, Zoro is rescued by a man named Terra, an alien who frequently visits the village. However, the situation soon takes an unexpected turn. In a last desperate attempt, Terra forces Euro to surrender at the village altar, summoning two demons whose presence will reveal the truth behind all this chaos.
