This unnamed chapter is an extra chapter of Yūki Tabata's Black Clover.
The Black Bulls have a nomotato pie-eating competition. Finral Roulacase is disqualified for teleporting the pies elsewhere. Magna Swing is disqualified after he overheats and burns his pies. Vanessa Enoteca is disqualified when she throws up. Asta vows never to give up, but Charmy Pappitson out-eats him and is declared the winner.
The chapter is loosely adapted in Episode 38, with the inclusion of additional squad members.
