The story begins with Gori, an 18-year-old young man, training in the Third Seal Village. In this village, human strength is divided into four tiers:
1. FCF – Humans with no power.
2. SLF – Humans with weak power.
3. TPL – Humans with moderate power.
4. FLP – Extremely powerful humans, so rare that only four people have ever reached this level.
Each person can use the Seal Power to gradually evolve to the next tier. Gori initially belongs to the FCF tier, and his seal is unique, composed of ten letters:
A, C, E, G, I, K, M, O, Q, S
The strongest letter is S, and the weakest is A. The closer one gets to A, the weaker the seal. Collecting all the letters ensures victory for the village and makes it the strongest among the five villages.
There are two types of seals:
Human seals
Village seals
Each village has its own seal, and there are five villages:
First Village – Seal 1
Second Village – Seal 2
Gori's Village – Seal 3
Fourth Village – Seal 4
Fifth Village – Seal 5
Gori's seal is the letter A, starting at 10% of its potential and gradually increasing as he integrates the remaining letters.

The Beginning of Training
Gori began his training under Master Hora, who taught him how to develop his seal and reach medium-level strength. He told Gori:
> "Every person has a seal and a type. To develop your type, you must face the Holga."
The Holga are creatures that feed on humans, divided into five tiers:
1. Weakest
2. Low
3. Medium
4. High
5. Leader (Horaid) and his elite followers
Holga often attack villages at dawn or around midnight.
Gori asked his master:
> "Are there weapons to defeat them?"
Hora replied:
> "Yes. There are special weapons, the first being DATR, which resembles a dagger. Anyone with any letter of their seal can wield it once they learn to control their primary physical power, known as SLF."
To obtain the DATR, Gori must complete a mission: climb Akura Mountain, retrieve the purple Akura flower, and merge it with his physical power.

First Encounter
While training in the forest, Gori noticed something moving at incredible speed. Concerned, he called out:
> "Is anyone here?"
Suddenly, a strange creature attacked him. Remembering his master's warnings about Holga, Gori activated his A Seal Power, although he did not fully control his physical strength yet. He struck the lowest-tier Holga repeatedly, but his strength was insufficient to defeat it quickly. He suffered significant injuries from using the power alone.
Fortunately, a stranger appeared and saved him, asking:
> "Who are you? What are you doing in this dangerous forest?"
Gori replied:
> "I'm Gori. I study under Master Hora."
The man introduced himself:
> "I'm Kari from the Fourth Seal Village. There are extremely rare skills. I only know three: Water, Fire, and Wind. Combining them with physical power amplifies your strength, and any energy used returns to you."
After sharing this knowledge, Gori bid farewell to Kari and returned home, where he met his parents, Haner and Hikaya, before sleeping to prepare for a new day.

Mastering Primary Physical Power
After a month of intense training, Gori mastered his primary physical power (SLF). He informed Master Hora, who was impressed and encouraged him to join the Seal School of the Third Village.
On his first day, Gori was placed in the second-grade class due to his current strength. Team assignments were made, and Gori was paired with Naxo and Lonia.
The test consisted of:
Entering a dangerous forest
Surviving for 30 days without dying
Fighting Holga and collecting reward tokens based on their level:
Level 1: 1 token
Level 2: 2 tokens
Level 3: 3 tokens
Level 4: 4 tokens
Level 5: 5 tokens
As the test began the next day, Gori trained diligently. But at night, he heard strange cries echoing through the forest…
