Chapter 16 (Quartet Knights)

Lightning Brat (雷小僧) is the 16th chapter of Tashiro Yumiya's Black Clover Side-Story: Quartet Knights.

Summary
At the Black Bull's base, Magna and Luck are informed that Yami and Asta had defeated more than a hundred Magic Knights that were controlled by the enemy with the captain of the Blue Rose, Charlotte. Magna and Luck shout about how they weren't there to help with the fighting. Yami asks if they have to act like this, which Asta replies that they usually do. Magna then comments about how they have to go to the Quicksand Dungeon that Karna will be at immediately, while Luck says that the Eye of the Midnight Sun will surely be there too along with how its full of strong guys. Yami tells them that only Asta and he will be going, which Magna wonders why. Yami replies that they are loud and annoying, which Magna tells Yami to not say such sad things. Magna tells Yami that Vanessa and Charmy are out on a mission, and that Grey and Gordon are not coming out of their room.

Magna points out how they are valuable assets to Yami, which Finral comments about how the Quicksand Dungeon is in an unknown place and that he is scared to head there with their current power level. Yami asks why Finral can't just take them there, which Finral replies that he has already told Yami that he can take people to places that he has not been before. Noelle says that since they need to take someone with them, that she will be heading with them. Asta says that the situation will be a lot more promising since she will be there, which Noelle replies that she is not going for his sake while thinking about how she would be sad if they left her behind. Magna asks if Noelle will be okay, since the top member of the Eye of the Midnight Sun that tormented them at the Seabed Temple, Vetto, will be there. Noelle says that she will be fine, since they have gotten stronger and that they will be defeating him.

Yami says that Noelle will also be joining them, which Magna says that he wants to go to. As Magna starts to cling to Yami, Luck starts to think about how he should ask to but winds up attacking Yami. As everyone wonders what Luck is going, Luck says that he is a member of the Black Bulls and that they will decide here and now if they will be taking them. Yami fends off Luck and says that Asta, Noelle, and Luck will be going to the Quicksand Dungeon and that he won't forgive Luck if he is useless. Luck hugs Yami and thanks him, but Yami tells Luck to let go or he will beat him. Magna says that he wants to go, but Gordon appears and says that they can clean together if he is free. Yami then tells Asta, Noelle, and Luck that the enemy is strong, and that he will kill them if they die.
