Silver Water Holy Sea Arc
When Anos attempts to communicate with Balandias' flying castle ship, Cartinas bumps the ship into the Demon King Train and leaves, telling them to know their place. The next day, on the day of his lecture, Cartinas recognizes Anos and becomes angry. However, he bursts into laughter upon hearing that Anos' world was equivalent to a bubble world and that he was a misfit, so Anos silences him by kicking his shoe into his mouth.

To their settle their dispute, Cartinas challenges Anos to the Silver Water Hierarchy War. Ottlulu gives Anos a day to learn, but this enrages Cartinas. He attempts to crush her neck for interfering, but Misa saves her. Nevertheless, Anos signs the contract and Ottlulu schedules their battle for tomorrow. Afterward, Cartinas starts the lecture and shows the class Balandias' hieroglyphics and the spell Balandialta, telling Anos to learn deep magic if they want a chance at defeating them.
