The story begins with a person named Gori, 18 years old, who was training in a village called the Third Seal Village. In this village, there are four layers of humans. The first layer has no power and is called FCF. The second layer consists of humans with weak power, called SLF. The third layer consists of humans with medium power, called TPL. The fourth layer consists of humans with great power, called FLP. The last type of humans is extremely powerful, so far only four people have achieved it. They are the top four who used the power of the seal. Any layer can evolve to the next layer. Gori belonged to the FCF layer, and his seal was special. The seal consists of ten letters: A C E G I K M O Q S. The best letter is S and the weakest is A. The closer it is to A, the weaker the seal. Collecting them all can achieve victory for the village and make it the strongest among all villages.
There are two types of seals: the human seal and the regional seal. Each village has a seal. There are five villages: the First Seal Village, the Second Seal Village, the Third Seal Village (Gori's village), the Fourth Seal Village, and the Fifth Seal Village. Gori's seal was the letter A, starting at 10% of its power, which gradually develops until it reaches 100% after completing the previous stages. Gori started training with his teacher, Hora, who aimed to help him develop his type to a medium level.
Hora told Gori: "Every human has a seal and a type. To develop your type, you must fight Holga. Holga are creatures that feed on humans and invade cities and villages. They also have levels: the first is the weakest, the second is medium, the third is high, the fourth is very high, and the fifth is the leader, called Horaid, along with his great followers who often attack suddenly, usually early morning or midnight."
Gori asked: "Are there weapons to defeat the Holga, or not?" His teacher replied: "Yes, there are some weapons. The first weapon is called DATR, which resembles a dagger. Anyone with any letter of the seal can use it. You will learn how to release your primary physical power, called SLF. To use it, you must train continuously and complete the mission to obtain spiritual physical energy. You need to climb Mount Akura and get the purple Akura flower, then merge it with your physical power."
Gori said: "How, teacher? I will do all this." Hora replied: "You will learn by yourself. Follow my advice and see the achievements you will gain." Gori answered: "Yes, teacher. I will do it. Tell me how many months it will take to get it." Hora said: "I got it in a full year. You may take more or less depending on your focus, patience, and effort." Gori said: "I will learn it faster than you, teacher. Thank you, we will meet soon."
Gori trained in the forest. During his training, he saw something strange moving very fast. He felt worried and shouted: "Is anyone here?" Suddenly, a strange creature attacked him. He remembered his teacher's words about the Holga, who feed on humans. He focused deeply and released his seal power, the letter A, even though he had no control over his physical strength. He attacked the weakest Holga, hitting it many times quickly, but the Holga did not die so fast. Gori got hurt because his power was seal-based, not physical.
Finally, someone came to save him. Gori asked: "Who are you, and what are you doing in this dangerous forest? Are you a Holga warrior?" The man said: "I am Kari, from the Fourth Seal Village." Gori was excited and Kari told him about skills. Gori learned three skills: water skill, fire skill, and wind skill, which combine elements with physical power.
Gori went home, met his father Haner and his mother Hkaya, and said: "I was training." He slept and after a month, he mastered the primary physical power. He informed his teacher, Hora, who then recommended that Gori join the Third Seal Village school. He began his first day at school.
Gori was assigned to the second-grade class because his power was SLF. Tests were done to form teams. Gori's team included a boy named Naxu and a girl named Lonia. The test was to survive in a dangerous forest for 30 days while Holga attacked them. Each Holga defeated gave them coupons: level 1 gives 1 coupon, level 2 gives 2 coupons, level 3 gives 3, level 4 gives 4, level 5 gives 5. The one with the most coupons wins.
At night, after training, Gori heard screams and went to see what was happening…
