Synopsis

The Exorcists begin fighting the twins, Jasdero and David. The Twins fire several kinds of bullets: blue (freezes everything it touches), red (ball of fire) and white (nulls the effect of their own power). The Twins want Allen to pay the debts General Cross tricked them into paying, which Allen claims are nothing compared to those he had. Soon after, the Twins fire a purple bullet covering the eyes of the Exorcists causing them to hallucinate. The Twins hide from sight and Allen loses Road's key in a sea of illusionary copies summoned by the Twins' ability.
