The scene is placed on Berkeley, California. Raymond Clark from his outer appearance is a look like normally second year high school student. The High School Institutes at USNA doesn’t have divisions by course. Among the group at High School Clark is one of the most talented magicians.
Raymond Clark is one of the operators of the hacking systems ECHELEON III. This system is a backdoor of another system called "Hliðskjálf, which acts on the brain waves of the operator through a virtual reality headset. Thus, this system will not leave a traces or allows recordings of any kind. This system is mentally operated, the operator uses a lookup field with results appearing in different windows.
This system is Raymond's favourite toy, the purpose of this systems is unknown and the operators are "persons". Raymond have 2 qualities to operate the system, fast reading and good memory. He's looking for incidents on USNA and then something catches his attention. Some missiles of the past era disappear during an inspection. These missiles have the C20 as the main explosive, however in due progress in nanotechnology this weapon is stop being produce. The investigation of a military base inside are suspicious because large quantity number of missiles and lack of security control of that missiles so he decide to investigate further. Raymond’s does not think about being a hero but with the help of Hliðskjálf he can help others. Raymond’s having fun with this because to know something is going to happen cause him great joy.
On certain USNA base, Colonel Balance was thinking about the disappearance of older missiles from a military base. This problem is strange because how missiles can disappeared like that. To enter military base they should go through 2 up to 3 security pass that is biometric screenings, wireless tags security and security guard. The most important is she don’t know who behind this. At the moment, she received a coded message and to decode this message she enter certain key, however she shocked because the sender is “one of the 7 sages”. She read the massage many times and understand of this problem. She now have to think about who she can trust to handle this information.
Lina is enjoying the day with Silvie, both are very close friends since the mission on Japan. Silvie feels that Lina is a troublesome sister that she cannot leave her alone. In addition, Lina also enjoys buying clothes and try new things. Lina received a coded massage, however the sender is not from military but from one of the seven sages. After finish decoding the massage Lina could not believe what she read, this message includes the parasite incident, the missiles problem and connection between them. Lina think that this massage must be a joke, but it very risky to ignore this information.
Lina think she can trust that information because parasites incident last year has been recorded in that massage. The missing missiles is make by terrorist and they going to used that to attack Japan and Lina know this matter is serious because relationship between Japan and USNA already been damaged by USNA. Although military power between two countries cannot be compared, the event in Korean Peninsula (Sorcerer Halloween), Japan demonstrated a strategic class magician that capable unleashing a huge power destruction crossing over the Pacific Ocean would change the balance power in the world. If thing going like this, a war between two countries would happen and will cause a disaster.
The mastermind of these crimes is the black sage "Jiedo Heigu", the Dark Sage. The information indicates that Jiedo has already escaped from USNA and now on the way to Japan, so Lina decides to act. Lina communicates by video with Colonel Virginia Balance. She explains that she received a massage from one of the 7 sages and that make Balance surprise. She pretend to know nothing and ask Lina to explain contain about that massage. Lina tell everything about all information and who is the culprit behind these. Lina ask Balance if true of missile is missing and Balance just simply says that there are rumours about that as well.
Lina tell something more, the real name of Dark Sage is Gu Jie, a man with the appearance of a middle-aged man, with white hair and face Asian feature. In the end Balance ask Lina if she want to go to Japan, which Lina respond yes. However Balance think this is not easy. The other strategic class magician Bart Roland is right now at base in Gibraltar and to send Lina to Japan is a matter much more complicated and dangerous. In the end, Balance tell Lina that she will be given an answer tomorrow.
The scene is a man looking at the sea. It’s Gu Jie, which right now he is way to Japan by sea, on a particular boat that been powered by solar energy.
Gu moved into USNA in 2054, which was ten years before the fall of Dahan. When he moved to USNA, USNA was still being called as "USA". Gu ran away from the Dahan. Kunlunfang Institute was researching in both modern and traditional magics. Modern magic faction and traditional magic factions were competing fiercely in order to gain more fund and human resources. At the end, traditional magicians were expelled from Kunlunfang Institute in 2054, and Gu and his students including Zhou ran away to USA. So, Gu should not have any grudge against Yotsuba or Japan because Yotsuba was one who took care of modern magicians faction in Kunlunfang Institute. So, no one knows why Gu aims Yotsuba as an enemy even himself. It may be a patriotism, or it may be an anger that Yotsuba took care of Gu's enemy (Kunlunfang Institute). Or, Gu may just need an enemy to sustain his organization. Only fact is that Gu has been creating a criminal network with defectors from Dahan and gather strength for revenge. Even he only knows (remembers) this much.
Zhou was Gu's last student and a subordinate, so Gu has to act. However, Gu is not a fighter type magician. In some ways, Zhou was stronger than Gu in the combat. Gu's specialty is creating a magical tool by using people as a part (Sorcerer Boost), a tool (Regenerator), and his last specialty is the ability to control corpse. Blanche has become weaker significantly by countries around the world. No Head Dragon was destroyed by the collaborated effort of USNA and Japan. Gu does not have any mean to fight against powerful magicians, so it took him one month to prepare a weapon (bomb from USNA) because his organizations have gotten weaker. Gu was not simply waiting several months since Zhou death. Gu realizes, he will not have a chance to revenge if he fails, so he was looking for the best opportunity to initiate the attack.
The payment for carrying Gu from USNA to Japan was teaching the magic of eternal youth to a captain of the ship. In truth, this magic only makes a person's look younger than their age, and it does not extend a person's lifespan and this magic was the main reason why Gu got expelled from Kunlunfang Institute. When politicians and powerful figures wanted the immortality, modern magician faction said it is impossible, but the traditional magician faction said it is possible. The traditional faction was already falling behind on the weapon development, so the success of this magic was needed in order to compete against the modern magic faction. Gu developed his magic and used on himself in 2049, and he used this magic on his students in 2050. Gu thought this magic was a success, but soon he realized his magic can only be applied on people who have a talent in sage arts (Senjutsu). If a person without any talent in Senjutsu uses this magic, it will shorten a person's lifespan significantly. Gu learned this when politicians provided their blood relatives as a test subject. Due to the failure of magic, traditional magic faction was eliminated, and Gu ran away from Dahan. Soon after their departure from Dahan, Gu also realized his magic does not extend the lifespan when his students were dying from the aging throughout twenty years.
On the STARS base in Roswell, New Mexico, Balance thinks about the situation and send a message to Kuroba Ayako. This is to inform Maya about the recent events. After a moment, she received a thank you. This is according an agreement between Balance and Yotsuba, this information is not publicize even high levels of USNA don’t know about this. On Japan Maya talks with Hayama about the missiles incident, but for her the main problem aren't the missiles, is the explosive inside them. After that they talks about the next meeting of the 28 families and the election of the 10MC, Maya orders to spread rumours about a terrorist attack.
Gu Jie is finally on Japan with his puppets and it's using "Hliðskjálf" to search information about the Ten Master Clans. His plan is not to kill leader of Ten Master Clans but he only want to target Yotsuba. His goal is to assassinate the entire Yotsuba clan, and the next attack wants to damage their public image.
The next day, Balance meets Lina and Benjamin Canopus. After discussing the reasons why she cannot send Lina to Japan, Balance is left alone with Conopus to discuss his mission. The mission is clear. Although over it to stop a terrorist attack, the real mission is to search and assassination of Gu jie. It is revealed Canopus have some connections with USNA politicians, there are some suspicious Heigu is one of the people helping this and the pro-humanity movement is involved in the government. Canopus's mission is to kill Gu Jie.
In the evening, Lina call Miyuki. After some praise from part and part, Lina congratulates Miyuki for his engagement with Tatsuya. Miyuki is surprised that Lina already know about that and Lina tell her that it is obvious since Yotsuba is famous. Miyuki ask her if she called her only to congratulate his engagement and Lina tell her that she wanted to tell something serious and Tatsuya also need to know about this. After Lina greeting Tatsuya, Lina explains the massage she g
