Blue TyrantEdit

When Lux's sword device ends up being mistaken for another girl's sword device, he takes the risks of being found out as a peeping tom when he infiltrates a building that is supposed to be off-limits to him, a male, just to retrieve his sword device, which is apparently Bahamut's sword device, resulting in him losing his calm over thoughts that his identity as the "Black Hero" might be revealed.

As he was just thinking about how to exit the building now that he retrieved his sword device, it seems news that an actual peeping tom got inside the academy grounds. He covered himself with a tablecloth in order to be mistaken for the peeping tom. However, Noct spots him but lets him go, pretending he was never there.

Just then, a scream of a girl who climbed up from another place struck where Lux was hiding. Because the incident disrupted his position, so his body also stood up slightly, the result was that he was exposed. But fortunately he was also dressed in tablecloths, so they didn’t see his face, but this was only a matter of time. Lux flew out of the shadows and ran through the passage in full force. He only heard screams of the girls who saw him came from behind. Lux kicked the door, jumped from the middle of the stairs and onto the grass, rushed into the empty campus, and then ran to school.

However, it was here that the girls who finished the body measurement returned and changed their clothes. That meant——In the vicinity of this, there was a high possibility that there were girls in uniforms who had already finished changing clothes. So he rushed to the stairs, up to the second floor of the school building. In a desperate moment, Lux took off the tablecloth in the last resort and pushed open the door of the reception room for guests. However, it was here where his senior and the leader of the Knight Squadron, was changing. He tried to explain himself, but he quickly hid when he heard that his pursuers were nearby. When Celis was questioned whether she saw someone come here and explained that there was a peeping tom, she glanced at Lux with a combination of shame and anger. However, she lied that she didn't see anyone and promised to help as soon as she was finished changing.

She let Lux go, and as soon as Lux exited the room, he heard footsteps approaching from the bottom of the stairs. Since downstairs was certainly dangerous, then he could only escape to the roof. When Lux embraced the last trace of hope by opening the door, suddenly someone from behind seized his wrist. It was Yoruka, who was wondering who made a sudden visit, but realized it was Lux. After Lux explained the situation, she helped him by offering a scenario to show his pursuers that a male wasn't on the rooftop: by wearing her uniform and act like it was a special tryst between girls. It worked, and he decided to hide out at the rooftop since it was clear from suspicions.

A few minutes later. After, Lux’s Sword Device came back to his hand without being noticed by anyone. It seemed that the Triads and Airi also cooperated under Celis’s command, and came looking for Lux on the rooftop and handed it to him. As he left the school building and wore the Sword Device he just got back, Lux sit on the curb of the courtyard and finally stroked his chest. Already most students had finished physical measurements and changed their clothes, and had come back to their rooms, Lux decided to take a rest for a while. It was a misunderstanding that Lux entered the indoor practice ground, but an incident appeared as an outside peeping tom was entering the school building, which made a serious commotion. Just then, a voice of a heavy and deep man called out to him and Lux realized that maybe it was him, who was mistaken as the peeping tom because the man explained that he entered without the guards' permission because he was in a hurry. They accused each other to be the said peeping tom, but the man declares that he was called directly by the Queen of the New Kingdom.

He told Lux to guide him to the Headmaster's office and there he interviews the princess, Lizesharte, first. Then the leader of the Knight Squadron, Celistia, was next. But it seemed both didn't get the seat to be the New Kingdom's Seven Dragon Paladin. After that, the man introduces himself as Singlen Shelbrit, Vice Captain of the Seven Dragon Paladins, who also represents the Blackend Kingdom. He reveals that he never intended to let those two take the seat of a Seven Dragon Paladin, but rather, he came here to scout out Lux for the position instead. But Lux turns down the offer.
