Chapter 24 (Quartet Knights)

Everyone's Power (みんなの力で) is the 24th chapter of Tashiro Yumiya's Black Clover Side-Story: Quartet Knights.

Summary
Rhya tells Vetto to complete his original task, so Vetto quickly retreats to the stone tablet and breaks it. The dungeon begins to collapse as its mana overflows. Rhya then opens a portal so that he and Vetto can leave. However, Asta and Yami Sukehiro refuse to allow this and charge over to the two terrorists, with Yami attacking Vetto while Asta attacks Rhya. Rhya warns that they need to leave quickly, but Yami provokes Vetto by insulting Vetto's despair.

Consumed by his anger, Vetto clashes with Yami. Annoyed, Rhya prepares to step in, but Asta interrupts Rhya and tells him to stop doing bad things since everyone can be forgiven. Noelle alerts Asta and Yami to her incoming Sea Dragon's Roar spell. Recognizing that it would be bad if the spell were to hit him, Rhya quickly opens a portal to escape the area. Noelle reckons that this Vetto should not know about this spell and will react the same way the original did. Vetto tries to block the spell but it rips off Vetto's right arm.

Rhya drops back in. Infuriated that Noelle is a royal, Vetto regenerates his arm and attacks her. Suddenly Asta and Yami appear behind Vetto. Rhya realizes that Noelle's spell was a decoy so Asta and Yami could get behind Vetto. Luck Voltia fires a spell at Rhya so he cannot interfere. Vetto tries to attack the two, but Yami and Asta's combined attack cuts into Vetto.
