Otonashi Tsukikurō (音無 月苦労) is the headmaster of National Knight Academy as well as the father of Otonashi Kaguya. He later revealed himself as Nyarlathotep.


Tsukikurō looks like a gentleman in his prime of life, wearing a refined suit on his body.


He hates and doesn't want to accept Hayashizaki Kazuki as the King of Solomon. He makes strange experiments on humans in his underground with blasphemous research that should be despised. He wants to draw out the power of Solomon 72 Pillar forcefully, Stigmata’s transplanting operation for the purpose of creating stronger Magika Stigma. Tsukikurō doesn't seem to value human lives including his own and will do anything to achieve his goals no matter what. At the end when he realized that he was an illegal magician he let himself get encroached by Nyarlathotep while thinking to himself that he's unneeded to anyone. After his defeat his Diva abandoned his body and he was left in a vegetative state. No one thought he would recover but he eventually awoke at the end of the series. As Kaguya spoke of hr plans for the future, he knew he did not have the right to say anything against it.



It's known that he had two children. His son was a Magical Swordsman who was killed years before the starts of the series, not much is known about it. He carefully brainwashed his daughter Kaguya from childhood making her blindly obedient to him and making her obsessed with being the most powerful Magical Stigma. With this programming she managed to reach level 10 in a record breaking 2 months. It's also why she challenged and ruthlessly cut down so many of her classmates at the academy in her first year, suppressing her normal kind and loving personality completely.


Volume 1Edit

When Lemegeton first appeared Hayashizaki Kazuki was treated as a possible illegal magician and was kept under close observation. His teacher Liz Liza Westwood implied at first that Leme could only copy low level summoning magic. But after Kazuki drove off Loki and used a full summon to save the life of Amasaki Mio. Liz was forced to tell them about the whole truth, about his being the potential King of the 72 Pillars and how his power increased along with the bonds with his classmates. She suggested that it was time to fully accept him as a Magic Division student. But many on the staff were fearful of that power and still regarded him as a illegal magician. Particularly Board Chairman Amasaki, who was an overprotective father. He refused to accept Leme as legitimate on face value. The headmaster agreed to step up their monitoring, and told them that if Kazuki proved in anyway untrustworthy the task of their subjugation would be given to his daughter, Kaguya.

Volume 2Edit

The Japanese government was in a panic about the fully materialized Loki and the threat he posed to them. They desperately wanted the help of the Germans, who were the followers of Norse Mythology and thus the experts. But relations with Germany were strained. A terminally ill girl named Charlotte Lieben Frau had contracted with a mysterious Diva in order to save her own life. As being an Illegal Magician carried a death sentence under German law she had fled to Japan to seek asylum as a refugee. They had investigated but could find no legitimate reason to turn her away and allowed her to enroll as a student. The Germans were still demanding her return but they could not hand over an innocent girl for execution without receiving international condemnation. The Germans sent their strongest knights led by Beatrix Baumgard to assist in the hunt for Loki. But it was clear what they really after was Lotte. So the Knight Order struck a deal where they would "look the other way" while Beatrix disposed of Lotte. This would have to be done during a quest so they could claim it was an accident. Any witnesses would be from the Knight Order or the Academy and could therefore be ordered to remain silent.

Liz had arranged for Lotte to be on the same team as Kazuki and Mio and they took on a quest to clear out a Haunted Ground. Beatrix waited until they were low on magic power and stamina before attacking. She was the Ace of the German forces and any average student would be no match for her. But those in power had badly underestimated Kazuki's abilities and ultimately he and his friends were able to escape safely. The chairman stormed into the Headmaster's office. He had been unaware of the plot and was furious that Mio had been in danger. Even though Beatrix had been told not to kill anyone but Lotte she was apparently the aggressive sort. He had found out about it because he hired two of his former students to keep an eye on Mio after she failed her first quest. This explained why two knights were unaware of the order not to interfere and had attempted to do so. Kazuki was becoming a thorn in their sides, not just for them but many of those in power in Japan. They had their own goals in mind for the Magical Stigma and had no wish to submit to the authority of a king. Especially a 15 year-old boy who they could not control. The Headmaster was already hatching a plot to destroy his reputation and drive him from the Academy. If it worked the title of "king" would be offered to someone "more worthy" (someone who could be controlled), Lotte would be out of the way and Mio would never be near Kazuki again. Her step-father struggled with his conscience for a few moments but finally agreed to help.

Kazuki had been ordered to take on a quest before the Germans left for home then stand aside and let Lotte be murdered in front of his eyes. But instead Kazuki's party had defied the odds by defeating Germany's ace and called the Knights to come pick her up. The Germans were outraged and demanded an explanation for it. The headmaster called an emergency meeting of the magical department staff to discuss what they should do. Liz suggested they merely tell them that Kazuki had acted on his own to protect a classmate. But the headmaster insisted this was not good enough. He was suddenly referring to Kazuki as an "Illegal Magician" who had been under observation. One who had injured one of Germany's knights and "abducted" his fellow student Lotte. Liz felt they were rushing to judgment but everyone else seemed to be very intimidated by the power Kazuki had displayed and no one else was speaking up to defend him. The headmaster also claimed that he had taken a Sacred Treasure and had injured two knights who had tried to confiscate it (a lie). Liz did not beleive this was something he would do but did not know the true story.

The Knight Order had placed an order to arrest both Kazuki and Lotte as Illegal Magicians. Lotte would be handed over to Germany and Kazuki would have his powers sealed and be sent to the Swordsmanship Division. Liz realized the decisions were out of their hands now, but suggested this might offend the Divas of the72 pillars if he really was their king .But the headmaster insisted there was no reason to recognize a 15 year-old boy as such and that Leme was probably manipulating him. Just in case, his stigma could always be forcibly transplanted into someone "more worthy" (someone they could control). This procedure was experimental and could leave Kazuki permanently incapacitated. But when the board chairman backed him up no one was able to make any arguments that could change things. The headmaster then tasked his own daughter Kaguya with the task of subjugating and arresting her two classmates. This struck Liz as particualarly cruel, as Kaguya was very fond of Kazuki. The group was attacked while they were still exhausted from fighting Beatrix. But two of their friends Hiakari Koyuki and Hikita Kōhaku came to help them. They escaped and sought refuge in the Swordsmanship Division.

Powers and AbilitiesEdit

As an older man well past the prime age for magic, he had almost no magic power at all. Likely one of the reasons he never realized he was an Illegal Magician was because his Diva could not make use of any powers while inhabiting his body. Therefore he was forced to achieve his ends by manipulating others to do his dirty work for him. This was why once Nyarlatholep fully manifested he made immediate plans to transfer himself into Kaguya, after Kazuki's King's Authority was transferred to her.
