For testing Touya's aptitude toward magic attribute, Linze showed him the magic stones. Using a blue magic stone, Linze was able to summon water from the stone while her twin sister, Elze could not summon any water using the same spell. Linze then mentioned that even though she could use water magic and her sister could not, she also could not use body strengthening magic but her sister could. Surprisingly, when Touya done the same procedure, the amount of water being summoned was excessive which meant that Touya has superior magic power than Linze. They then pardoned themselves after making ruckus inside the cafe. Later, Touya spent the day learning the writing system of the world's language. Surprisingly, Touya was able to memorize the alphabet quickly than he would expected.
