is the 90th page of Yūki Tabata's Black Clover.

Summary
A flashback of Fanzel teaching his students (which include Mars and Radols) that their powers are for protecting people. Fanzel hits Radols but thinks about how Radols specializes in fortification and that will have to hit Radols with everything that he has. Mars appears behind Fanzel, which Fanzel notices, and says that you are going to need to stop right there. Fanzel thinks about how Mars was the strongest student that he had ever had and that he will have to keep his distance from Mars. Fanzel attacks with a spell and manages to push Mars back. Fanzel turns back to Radols and attacks with a spell with everything that he has. While attacking Fanzel thinks about how Radols is an anomaly who didn't have an elemental type but has a larger well of mana than anyone else. Fanzel also thinks that if Radols has learned a powerful long distance spell then they would be in trouble, and that he needs to take Radols out. Radols yells out to stop and smiles as he says that he will be stuffed, which shocks Fanzel.

Fanzel backs off and notices that Radols doesn't even have a scratch. Radols tells Fanzel that after Fanzel left, he had taken the military's reconstructive surgery and had gotten the ability of Absorption and Expulsion. Radols also explains how his ability works and releases his mana. Fanzel wonders what kind of power this is since he can feel multiple magic powers swelling up together. Radols points out that Fanzel had brought someone he cared about here and that he should go to save her. Fanzel leaves to save Domina, which Radols launches a spell that manages to destroy the area. Radols goes to find Fanzel and notices that he had wiped out his men too. Radols finds Fanzel, who managed to protect Domina in time. Radols is surprised that Fanzel did bring someone important to him here and mocks Fanzel while kicking him away. Fanzel picks Domina up and recognizes her as the one who ran away with Fanzel. Fanzel asks Radols to stop since he need to use his power for good, but Radols tells him that he never thought of using his powers to protect. Radols reveals why he did all that training and calls Fanzel a coward for leaving the kingdom. Domina attacks Radols and says that her husband is not a coward.

Radols tosses Domina into the air and says that he will start by kill Domina. Fanzel yells for Radols to stop but Radols launches a blast of mana at Domina. Mars blocks the blast with one of his spells, which surprised Radols. Mars says that his power is for protecting people and also says that Fanzel's teachings did reach him. Fanzel is shocked and asks what Mars is doing.
