Second Sindria Arc
When Judar arrives at Kou Empire's Army's Base in Balbadd, Kouha says that Judar is late and grabs his arm. He tells Judar that Balbadd is a sultry country and that he is really sweating. Judar says if that's the case, Kouha should get away from him, as Kouha is the one making Judar sultry. Koumei Ren appears and asks where Judar has been up till now, as they couldn't get in contact with him, and he was worried. Judar greets him and says that his gloomy face is the same as ever. Judar then gives Koumei a gift as an apology for his lateness. Koumei asks what it is and Judar says its a specialty from Sindria. Kouha is curious and asks his older brother to let him see it.

They go to meet Kouen Ren, who is in the throne room with the Left General, Kokuhyou Shuu, and the Right General, Seiryuu Ri, waiting for Judar to return. Kouen says for Judar to make him wait, he must've brought him an interesting present. Judar says he has, that he told Sinbad, "Why don't you fight a war, against us?" Kouha and Koumei are surprised that he did this without the Emperor's permission. Kouen starts laughing, and says that's very befitting for the Magi of his empire. Kouen tells everyone that for his empire that will rule the east, the day in which it will rule the world is imminent.

World Exploration Arc
Kouha is on a caravan heading to Magnostadt with his attendants when Aladdin joins them. The caravan is then attacked by thieves using Magic Tools and before Aladdin could retaliate, Kouha jumps in front and starts to attack them with his Metal Vessel, Nyoi Rentou. He asks if they are trying to ruin the mood of his long-awaited journey. Kouha asks if he should execute the old men. One of his attendants says that they need to pass by unnoticed, but another one says it is useless. Kouha begins the onslaught by showing what Nyoi Rentou can do, which is elongate or retract at Kouha's will. He cuts the attacks from their Magic Tools, the thieves' hands, the horse's heads, and begins to slice the thieves and horses into pieces.

After the fight, back on the caravan, Kouha asks who the dirty brat, Aladdin, was. One of his attendants says Aladdin has been traveling with them for a while now. When Aladdin realizes that they are traveling to Magnostadt, Kouha informs Aladdin that only special exceptions like him and Magic Users can enter their. Aladdin says he's a Magician and he's going there to study. The driver of Kouha's cart informs him that they will arrive in 9 days. Eight days later, Kouha dropped Aladdin off at the Magician's entrance into the capital. Kouha tells Aladdin that he will have someone pick him up there and wishes him good luck.

Soon after, during a diplomatic negotiation with Matal Mogamett, he is informed about the death of his father. Mogamett says that they are in a dire situation now and suggests that Kouha return home to the Kou Empire as soon as possible. Kouha agrees and says that the warning he gave Mogamett isn't a lie: "The Kou Empire will invade Magnostadt soon. Before that happens... choose between submission or destruction." When he is outside, Aladdin flies down to greet him. Kouha says its been a while since they've seen each other and wants to hang out, but his "pops" kinda died. Aladdin realizes that Kouha's father is the Emperor of the Kou Empire. Kouha says that he will leave things in the care of his attendants while he is gone. He adds that the next Emperor will obviously be his brother "En", and there isn't a single force left that can oppose the Kou Empire from inside it.

A day after he arrived in the Kou Empire, Kouha heads to the funeral with his siblings. There, Gyokuen Ren greets her children. Kouen asks if the Emperor died of an illness, Gyokuen says that he was ill for a long time, and it suddenly became worse. Kouha gets disgusted when Gyokuen grabs Kouen's arm and asks if he will support her, and calls him her most loved son. Kouha is talking to Mei and says that Gyokuen always fawned over En, and now it seems she has finally decided to move on from him. He asks Mei if in that case they don't need to hear the testament, but he only says to Kouha mind his manners and look foward, since the priests will begin to read the testament. During the reading of the Emperor's will and testament, Kouha thinks that the next Emperor must be En, as everyone who has rights to the succession are under his command, except Hakuei Ren and Hakuryuu Ren. Kouha is surprised when the testament stated that the Third Emperor of the Kou Empire is Gyokuen Ren, and that she will be assisted by the Imperial Piests in tending all national affairs. An argument ensues and the tension starts to rise, until Hakuryuu bows to her and asks her to take the throne, and no one but her can do it. The Imperial Priests start chanting that, which surprises Kouha, Hakuei, Kougyoku, and Seisyun Ri.

At the end of the day, he talks with his brothers about Al-Thamen. Kouha tells En that what happened in Magnostadt wasn't what they expected. When he was negotiating with them, even though Mogamett faltered when Kouha mentioned Gyokuen, the chancellor refused to collaborate. Mei mentions that Magnostadt is just like the Kou Empire was a few years ago, with their mass-production of Magic Tools, and the sudden development and increase in their military force. He suspects that Al-Thamen is behind it. En states that it is the result of their Magicians that they were able to expand their strength to that extent, and that if they would come to oppose the Kou Empire, they would be a frightening country.
