After visiting the Angel's Agape Realm, Eros returned to the human world. Though he didn't get the answer he was looking for from the Mother Angel, he felt relieved that Sienna would back them up against Zaki.
Zaki was the most strict and scariest leader of the grim reapers. But don't get it wrong. He looked scary not because of his appearance but because of his attitude and behavior.
In the grim reaper's realm, Zaki was the rule. Failure to follow the rule was equivalent to endless suffering from torture, severe punishment, and even death.
Death did not literally mean the grim reaper would die just like humans. The death to them meant they would be banished from the grim reaper's realm and they would lose their immortality.
The Angel's Agape Realm of cupids had the same punishment but the grim reapers were more strict when it came to implementing their rules.
