Magic Sword Tournament Arc
Not long after enrolling in Anos's class, Lay quickly turned down an invitation to become a group leader and wanted to join Anos' team instead. Lay saw that he was the strongest student in the class, but because their status were different, Lay let his distaste of royalty show. But Anos refused, saying that if he wanted to join, he would need to show adequate strength. Anos then put Lay and Misa in the same group, telling them they can join if they do well against him in the upcoming battle exam.

To get ready for the Magic Sword Tournament, the class had a Great Demon Sword Training with two of the Seven Elder Demon Emperors, Gaios Anzem and Ydol Anzeo. But Lay and Anos easily beat their instructors.

The next day, the two teams met at the forest outside Delzogade for the battle exam. Lay invited Anos to a fight just the two them, and lent Misa his sword Initio so that the rest of their teams can fight each other. Although Anos was using a tree branch he picked up from the ground, Lay was barely able to keep up and the landscape was destroyed as they kept fighting. In the end, both Lay and Misa lost, but Anos acknowledged their strength and lets them join.

After the battle exam, Anos brought Lay and Misa to his house for dinner. Once everyone finished their meal, Lay took the opportunity to talk to Misa alone in the garden. Misa thanked for him for asking Anos to bring her along and commented how he doesn't really care about the royalists or unificationists, making him laugh. Lay then asked her about being a half-demon half-spirit, showing some familiarity with the topic, but Misa replied that she was okay.

The next day, their homeroom teacher informed Lay that he was chosen for the Magic Sword Tournament, alongside Anos. In preparation for the event, the academy closed down, so Lay went to the Lognorth Magic Clinic to visit his mom. While there, Lay stumbled upon Anos and Misha, and told them about his mom. Anos offered to make her healthy again, but Lay just thanked him for the offer. After Lay leaves, Misha told Anos that Lay seemed off.

At the day of the tournament, Lay easily defeated his first opponent and was introduced as a member of the Lognorth Magic Sword Association, a prominent royalist organization, alerting Anos and Misa that something was wrong. The two waited for Lay at his waiting room, but Lay shrugged them off by saying that the Royalist offered him enough money for a lifetime and the title of Demon Lord. Lay left the room shortly after he and Anos traded blows, but not before Anos is able to confirm that there was a magical device inside of Lay that could kill him.

After winning all their matches, Lay and Anos met at the finals. They were evenly matched, but their match concluded with Lay cutting off Anos' left arm, and Anos piercing Lay's chest with his sword after shattering Lay's sword. Melheis, who was spectating the match under the disguise of an Ural Owl, took advantage of the situation and trapped them in a different dimension. He planned on teaming up with with Gaios and Ydol to defeat Anos, but the two of them were beheaded by Lay, who was was pretending to be dead after being stabbed by Anos. What Anos destroyed wasn't Lay's root, but the magical device that was making him compliant.

Melheis then reveals that he took Lay's mom hostage, promising to release her if Lay joined the Royalists, but Lay refused and broke into the dimension where she was being held at. Melheis fired Beno Yeven at the two in order to force Anos to use up his magic power to protect them. Lay asks Anos to create a sword so he can slash away Beno Yeven, but Lay isn't able to keep up and loses hope. Sheila encourages him and uses her remaining power to return to her true spirit form, a sword which Lay uses to slash Beno Yeven and destroy the dimension where Melheis was hiding in. Before Sheila fades away, she is able to tell Lay that she loves him, making him tear up.

With Melheis outside his hiding place, Anos is able to defeat him and return them to the tournament Arena. Because Lay's sword was broken, Anos is declared as the winner, while medics and eventually himself Anos tend Lay's injuries. For his victory speech, Anos told everyone about a sword that was crafted with something other than magic, the very legends that made up Sheila's existence, thus he was able to revive her. After Lay reunited with his mother, Lay shook Anos' hand.
