The supernatural danger surrounding the Clover Kingdom continues to escalate as Studio Pierrot unveils the official preview images and story synopsis for Black Clover Season 2 Episode 3 (Episode 173 overall). Titled “Black Guardian,” the upcoming installment shifts its focus toward a devastating demonic threat emerging from the underworld while the kingdom’s elite defenders are away.
Following the return of the series this autumn, the narrative builds directly toward the high-stakes Spade Kingdom Raid arc. Fans can stream the new episode globally on Crunchyroll on Saturday, October 17, 2026, following its standard broadcast on TV Tokyo and affiliated networks in Japan.
Underworld Gates Open and Spade Kingdom Under Siege
According to official plot details, the gates of the underworld finally open wide in Episode 3. Low-ranking devils pour relentlessly out of the underworld’s first level, threatening total destruction. To counter the invasion, the Resistance Army-led by Albert-joins forces with the Magic Knights of the Clover Kingdom, including Maxa and his companions, to protect the citizens of the Spade Kingdom.
However, the crisis quickly spreads. A massive giant demon suddenly materializes within the Clover Kingdom itself. Because the Magic Knight Captains are currently absent, ordinary citizens are left in mortal danger, setting the stage for a dramatic rescue operation.
Asta Steps Up With Devil Union and Anti-Magic
Stepping into the breach to save the kingdom is Asta (voiced by Gakuto Kajiwara), who relies on his unique Anti-Magic abilities. To handle a threat of this magnitude, Asta must tap into the supreme power of “Devil Union,” mastered through synchronization with his companion devil, Liebe.
Preview imagery highlights the intense physical strain required for Asta and Liebe to maintain their synchronized form. The episode emphasizes the deep cooperation and emotional bond between the duo as they push past ordinary limitations.
Dark Triad Power Reaches 100 Percent
Compounding the chaos, the preview confirms a major escalation involving the primary antagonists. The Dark Triad’s devil power officially reaches 100 percent, signaling that the conflict involving the underworld and the Tree of Qliphoth ritual is entering a critical phase. With Dante, Vanica, and Zenon operating at maximum strength, the upcoming battles will demand absolute coordination from every surviving Magic Knight.
