I get your second explanation.
I noticed there is a RED RIDING HOOD (the one next to Cybella)
She, along with Aladdin & Snow White are the Fairy Tale series which have HEX effect.
When Red deals critical attack, she has 95% chance to trigger Others in aura to attack and hex.
When Aladdin deals critical attack, he has chance to Refresh others and applies hex.
When other is attacking in Snow's Aura, they have chance to 'trigger' themselves to attack again and hex.
