Rin is intent on wiping out the demons, but without a plan, it'd be too easy for some to escape. With that in mind, Ysley contacts another Idaten named Prontea to formulate a strategy, while the demons begin their own divide-and-conquer campaign against their divine enemies.
For them to split up immediately 
after the battle with Nickel...
...أن يتفرّقوا فوراً بعد معركة نيكل
Dass sie sich direkt nach dem
Kampf gegen Nickel aufteilen …
Alors qu’ils viennent
d’affronter Nickel ?
Ma se si sono separati
subito dopo la battaglia contro Nickel...
Mas se espalharam assim
que mataram a Nickel...
Но зачем разделяться
сразу после битвы с Никель?
