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

Summary
A flashback of Fanzell teaching his students (which include Mars and Radols) that their powers are for protecting people. Fanzell 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 Fanzell, which Fanzell notices, and says that you are going to need to stop right there. Fanzell thinks about how Mars was the strongest student that he had ever had and that he will have to keep his distance from Mars. Fanzell attacks with a spell and manages to push Mars back. Fanzell turns back to Radols and attacks with a spell with everything that he has. While attacking Fanzell thinks about how Radols is an anomaly who didn't have an elemental type but has a larger well of mana than anyone else. Fanzell 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 Fanzell.

Fanzell backs off and notices that Radols doesn't even have a scratch. Radols tells Fanzell that after Fanzell 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. Fanzell wonders what kind of power this is since he can feel multiple magic powers swelling up together. Radols points out that Fanzell had brought someone he cared about here and that he should go to save her. Fanzell leaves to save Domina, which Radols launches a spell that manages to destroy the area. Radols goes to find Fanzell and notices that he had wiped out his men too. Radols finds Fanzell, who managed to protect Domina in time. Radols is surprised that Fanzell did bring someone important to him here and mocks Fanzell while kicking him away. Fanzell picks Domina up and recognizes her as the one who ran away with Fanzell. Fanzell 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 Fanzell 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. Fanzell 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 Fanzell's teachings did reach him. Fanzell is shocked and asks what Mars is doing.
