Previously on Black Clover:
Noelle and Leopold defeat Rades final zombie, No.3 David. Fuegoleon examines Rades Grimoire and finds that it contains a single page with only one spell, meaning necromancy is all he is capable of. Rades is revealed to have a magic item in his ear transmitting someone’s voice that warns Rades to follow their master’s plan in future. A spell suddenly activates, the zombies having been used to lure Magic Knights into teleportation traps that send almost every Magic Knight in the city to far away locations. Catherine attacks the city and begins draining the mana from every magic user in the city, aging them while her she grows younger. Yuno, who escaped the trap, battles with her and Catherine reveals the invasion was aimed at one person, Fuegoleon Vermillion, who is suddenly transported away to a different location than the other Knights. Yuno is hit by curses stealing his vision and hearing. He almost gives up but he realises that with his sight gone he is more attuned to the flow of mana. He summons Sylph to manipulate all the mana in the city to strike Catherine with a massive hurricane. Meanwhile Fuegoleon is approached by a mage he recognizes.
Tonight: Captain Fuegoleon is swallowed up by spatial magic right in front of Asta and the others. Noelle realizes that the spellcaster must be nearby, since the spell pinpointed Fuegoleon. Asta finds the spellcaster, but something unbelievable happens next.
