Demon 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 differed, Lay let his distaste for royalty show. But Anos refused, saying he would need to show adequate strength if he wanted to join. 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 Demon Sword Tournament, the class had a Great Demon Sword Training with two of the Seven Demon Elders, Gaios Anzem and Ydol Anzeo. But Lay and Anos easily beat their instructors.

The next day, the two teams met at the forest outside Delsgade for the battle exam. Lay invited Anos to a fight just the two of them and lent Misa his sword Initio so that the rest of their teams could fight each other. Although Anos was using a tree branch, he picked up from the ground; Lay could barely keep up, and the landscape was destroyed as they kept fighting. In the end, Lay and Misa lose, but Anos acknowledges 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 him for asking Anos to bring her along and commented that he doesn't 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 Demon Sword Tournament alongside Anos. In preparation for the event, the academy closed down, so Lay went to the Lognorth Magic Hospital 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 tells Anos that Lay seems off.

On the tournament day, Lay easily defeated his first opponent and was introduced as a member of the Lognorth Demon Sword Association, a prominent royalist organization, alerting Anos and Misa that something was wrong. The two waited for Lay in 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 could 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 Owl, took advantage of the situation and trapped them in a different dimension. He planned on teaming up with Gaios and Ydol to defeat Anos, but the two of them were beheaded by Lay, who 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 Ievun at the two to force Anos to use his magic power to protect them. Lay asks Anos to create a sword to slash away Beno Yeven, but Lay can't keep up and loses hope. Sheila encourages him and uses her remaining power to return to her true spirit form, a sword that Lay uses to slash Beno Yeven and destroy the dimension where Melheis was hiding in. Before Sheila fades away, she can tell Lay that she loves him, making him tear up.

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

Hero Academy Arc
*More information to be added.*

After the school exchange with the Hero Academy, Lay put in motion his 2,000-year plan to start a war between the humans and the Demon King again. After realizing that humanity's hatred will never disappear until one side is completely destroyed, Lay took the role of the Demon King of Tyranny Avos Dilhevia and planned on letting them kill him to end the war once and for all.

Silver Water Holy Sea Arc
After the fight against the gods, Lay loses Evansmana and can't summon it. He eventually finds it in Azesion's mountains with Misha's help, but when he touches it, Evansmana goes berserk, and bits of the handle come off. He tries again, but an unknown man stops him as Evansmana tries to return to its original form. The man calls him a thief, but Lay replies that if Evansmana chooses another candidate, he will accept it.

A sword fight then begins, but Lay wins and holds Siegsesta to his opponent's neck. The man, Balzarondo, explains that Evansmana didn't have its original handle and shows him the real one. Evansmana flies off towards it, but Lay catches it. After talking to Anos with Leaks, he lets it go so they can follow the man outside the world. Balzarondo holds the sword, which sheds a holy light, showing that he is worthy. As per his word, Lay lets Balzarondo leave. }}
