Yami and Charlotte survive the mass while Yami saves enough magic for one last Dimension Slash. Secre realizes that while Zagred created Asta's Grimoire, it was another devil who gave it anti-magic. Yuno manages to gather the remains of Lumiere and Licht's magic to forge an air sword capable of hurting him while Asta manages to overfill his sword with anti-magic, turning it into the Anti-Magic Demon-Slayer Sword, Black Divider. Lumiere is highly impressed with both of them. Working together Asta manages to stab Zagred's heart, only for it to reappear undamaged. Enraged, he summons even more mass. Lumiere and Licht decide they must let Asta and Yuno fight the devil while they use the Demon Dweller sword to cast a spell to protect everyone in the dungeon from the mass. Even though they are an impossible distance away Yami decides to aim his Dimension Slash at Zagred using only ki detection. Asta and Yuno both stab him, but Asta finally runs out of Anti-magic. Zagred prepares to kill them both but Yami casts his largest Dimension Slash, the Equinox, and cuts Zagred in half. Secre uses her sealing magic to help Asta recover, and as she flashes back through all the enemies she has watched him defeat through sheer willpower, she declares he will become the next Wizard King. Spurred on by her faith Asta resummons his anti-magic and finally cuts Zagred's heart in half. (Source: Wikipedia)
