Black Clover

Synopsis

Shortly before Kabwe contacted the Wizard King it is shown he and the Banishers were betrayed by Dazu and the Believers who infiltrated the Banishers to take control of Asta’s 5 leaf Grimoire. They believe that if they gain Devil powers they can become like Asta who became a Magic Knight despite possessing no magic. With Kabwe and the Banishers dead and the Believers exposed the Wizard King orders Yami to destroy them and retrieve Secre and the Grimoire. Following Kabwe’s signal they find the Banishers hideout and learn from a villager it was the home of Bow, an apothecary with weak magic. Following her directions they find Dazu’s home where her husband and mother-in-law died. The Wizard King deduces the Believers want to get to the Spade Kingdom to offer Secre and the Grimoire as gifts to Megicula in exchange for his power. During several days of pursuit Yami notices wherever the Believers go people disappear from villages, people with weak magic tempted into joining the Believers to gain Devil powers. Following them over the border into the Spade kingdom Asta, Noelle and Magna finally catch up to the Believers who have managed to recruit hundreds of members.
