Episode 45

The Guy Who Doesn't Know When to Quit (諦めの悪い男) is the 45th Page of Yūki Tabata's Black Clover.

Summary
Despite their combined spell, Magna and Luck weren't able to beat Vetto. Magna and Luck collapse on the ground. Vetto goes to give the finishing blow but Asta blocks him. Asta tells Vetto that he'll take on the challenge of beating him. He manages to slice Vetto across the stomach. Asta tells him that they know that the Eye of the Midnight Sun is up to something. Vetto says that he isn't going to tell him because he doesn't have any magic. He tells Asta to attack him. Asta and Kiato attack Vetto. They barely graze him. Vetto says that he didn't expect much from them. Asta and Kaito tell Vetto that they'll show him what they can do. They run at him as Yami Sukehiro and Gifso watch. Gauche Adlai comes up against another mage that is good with chain magic. They fight but the mage is very strong and has Gauche running for his life. He is sitting trying to think of what to do when a crab comes and pulls at his pants leg. Gauche returns to battling the mage but this time shows up with his double. The mage defeats the double and leaves Gauche open for attack. Or so the mage thinks. Instead, Gauche appears behind the mage and uses his mirror magic to take him out. He was about to do this with help from Grey.

Grey and Gauche go to find Charmy but become entangled in vines. The vines start to drain their magic and another mage appears. He tells them that he's waiting for their magic to leave them and then he's going to torment them. Gauche tries to get Charmy to help them but she's fast asleep. Gauche believes that he has to do this on his own but remembers how Asta told him that they are a team. Gauche comes up with a plan to have Grey transform a rock into a piece of meat. He then tells Charmy that someone is trying to steal her food. Charmy wakes up and attacks the vine mage. Charmy destroys him but is upset that the rock isn't really meat. Suddenly, Grey's current form starts to wear off and Grey's true form is revealed. Grey is actually a girl and she's embarrassed to not be transformed into something else. Charmy is shocked to also learn that Grey is older than her and that she and Gauche are the same age.

Meanwhile, Asta and Kiato get hit into a wall as they are no match for Vetto. Vetto lists all of Asta's failers and tells him that he doesn't know when to quit as Asta continues to come at him. That arrogance is what will mortally wound him. Vetto holds Asta up by his arm as he begins to squeeze. Asta bites Vetto just as Kahono and Noelle arrive.
