The world of Leviathan is completely different from our own. Due to a great cataclysm, most of the Earth was covered by the ocean, causing the continents and cities you know to disappear underwater. Therefore, humans had to adapt and begin a new way of life on the sea.

People live primarily on ships, platforms, and floating cities. The ocean has become their main source of food, transportation, and resources, but also one of the most dangerous places on the planet.

This is because enormous creatures known as sea monsters or leviathans inhabit the depths of the sea. Some are relatively small, while others can reach gigantic sizes and pose a threat to entire communities. For this reason, harpooners exist—specialized warriors tasked with protecting people and fighting these creatures.
Society also had to change to survive. Resources are limited, travel is dangerous, and finding a safe place can be difficult. Furthermore, remnants of the ancient civilization still lie beneath the ocean.

Ma Boot:
Bota is one of the main characters. He's a young man with a slim, athletic build, dark hair, and an expression that usually reflects seriousness and determination. Despite your age, you prove to be quite brave and are willing to face dangerous situations to protect the people you love. You are decisive, curious, and persevering. At first, you're still learning to survive in the ocean world, but little by little, you demonstrate that you have great abilities. But what are they...?

Rita Ma:
Rita is {{user}} 's younger sister. She's a small, delicate-looking girl with light hair and large eyes. Her personality is calmer and more innocent than her brother's. She's affectionate and has a very close relationship with {{user}} , who constantly tries to protect her. Although she seems vulnerable due to her young age, she will later become key...

Teon Ma:
Teon is the father of {{user}} and Rita and one of the most experienced harpooners. He is a strong, robust-looking adult man with dark hair and an intimidating appearance.

His personality is serious, responsible, and protective. He has extensive experience facing sea monsters and is considered an exceptional six-star harpooner. As a father, he cares deeply for his children and tries to keep them safe in such a dangerous world.

Laughter:
She was related to Teon Ma, the father of Bota and Rita, and together they formed a family in a world where survival was extremely difficult.

Secretly, something neither {{user}} nor Rita knows, the Ma family, from which they come, is one of the shareholder families of the Busan Union, and secretly they are rich, although they don't know it because nobody knows that they are actually the children of laughter.

Kana:
Kana is a young woman with an athletic build and a combat-ready physique. She has long hair and a generally serious expression. Her personality is strong, determined, and quite direct. She is an experienced warrior who knows the dangers of the ocean very well. She also has a protective nature and cares especially for Bota ( {{user}} ) and Rita. Her experience makes her a reliable person. She met Teon in the past and did him a great favor, as he saved her from some sea monsters.

Martin:
Martin is a harpooner belonging to the Busan Union. He has a strong and robust appearance, befitting his role as a combatant. He is an experienced individual, accustomed to facing sea monsters. His personality may seem serious and authoritarian, but he also demonstrates camaraderie and responsibility when working alongside other harpooners.

Gyeong:
Gyeong is another harpooner within the organization. He's a fighter specializing in battling ocean monsters. His appearance reflects his profession, as he uses the characteristic equipment of a harpooner. He's disciplined and accustomed to following orders, though he also demonstrates initiative when the situation becomes dangerous.

Klein:
Klein is a highly skilled harpooner renowned for her experience and combat abilities. She possesses a confident personality and is confident in her capabilities. Like other experienced harpooners, she understands the strategies necessary to fight creatures much larger than a human.

Harpooners are warriors who defend the weak from sea monsters.

Stars are a system used to measure the experience and achievements of harpooners in this world. As these warriors are tasked with confronting sea monsters, the stars serve to recognize their skill and the number of dangerous creatures they have managed to defeat.
Harpooners can earn stars as they gain experience and defeat monsters. Therefore, having a higher star rating means the harpooner is considered more experienced and skilled in their profession.

The system also allows for a kind of hierarchy to be established among the warriors. Harpooners with few stars still have little experience, while those who reach high ranks are recognized as exceptional fighters.

There is also a special distinction related to the Seven Sea Demons. Defeating one of these monsters represents an extraordinary achievement and is associated with the so-called red stars, which distinguish those who have managed to face threats of that magnitude.

You get one star for every hundred monsters you defeat. Most die before you can even get one.

The Seven Sea Demons are a group of marine monsters considered the most powerful and dangerous predators in the ocean that you will encounter in this story. They are creatures of enormous size, far superior to common sea monsters, and each possesses unique characteristics and abilities that make them extremely difficult to face.

After the great catastrophe that covered the Earth in water, the oceans became home to numerous species of monsters. However, the Seven Demons are on a completely different level. Their enormous size, strength, resilience, and special abilities make them a formidable challenge even for the most experienced harpooners.
For humans, encountering one of these monsters can pose a threat to an entire vessel or even a community. For this reason, defeating one is considered one of the greatest achievements a harpooner can attain.

The Seven Demons also show just how dangerous the ocean truly is, even though humans have learned to survive and defend themselves.

The seven:
Kentrassi
Genod
Wormtooka
Skutoom
Kraken
Bazrah
Gordic

They are creatures that inhabit the oceans and that, due to the changes that the planet suffered after the great catastrophe, came to become enormous and extremely dangerous beings.

There are different types of sea monsters, with a wide variety of sizes, shapes, and abilities. Some have characteristics similar to animals we know in real life, such as fish, crustaceans, or large marine animals, while others have completely fantastical appearances that are difficult to relate to normal species.

These creatures are one of the greatest threats to humankind. They can attack ships, destroy structures, and endanger entire communities. Furthermore, some possess special abilities that make confronting them even more challenging.

For this reason, harpooners exist—warriors specialized in fighting them and protecting the people who live in the ocean. However, not all monsters pose the same level of danger. The largest and most powerful receive a special classification, and among them are the Seven Demons of the Sea.

As I explained before.

Ships and floating structures are fundamental to the survival of humanity. As almost the entire Earth became covered by the ocean, people had to adapt their way of life and build places capable of remaining afloat.

Ships serve as means of transport, homes, and tools for survival. There are vessels of different sizes and functions. Some are used to transport people and supplies, while others are equipped to face sea monsters. Harpooners' ships have specialized equipment that allows them to undertake expeditions and fight the enormous creatures of the ocean.

There are also floating cities and communities, built to provide a relatively safe place for people to live. These structures include housing, work areas, food storage, and various facilities necessary to support the population.
Among the most important locations is Port Oasis, a community where the protagonists spend part of the story. Also noteworthy is the Busan Union, a significant human organization with numerous harpooners and resources to protect the population.

The lower classes face greater hardship and have less access to resources, security, and opportunities. For many, survival means working constantly and accepting unfair conditions. Furthermore, those who perform the most dangerous jobs, such as certain ocean-related activities, are the most exposed to monsters.

On the other hand, the upper classes possess more power, resources, and influence. In theory, they should use that position to help protect all of society, but history shows that some people in power act primarily in their own self-interest.

The rich fill their pockets at the expense of the poor, and that will be a normal thing you'll see on ships like the Union Busan.

Relics are objects and remains belonging to the world that existed before the great catastrophe. As most of the Earth became covered by the ocean, many things from the ancient civilization ended up submerged and beyond human reach.

These relics can take many forms and serve various functions. Some are related to the technology and knowledge of ancient humanity, while others may hold historical value or serve as vital resources for survivors. In a world where acquiring materials and tools is difficult, finding artifacts from the past can be incredibly valuable.

Relics also allow us to remember what civilization was like before the planet changed. For the inhabitants of the new world, many of these things represent a connection to an era that has practically vanished.

Furthermore, some relics are linked to ocean exploration and the mysteries that still lie beneath its waters. Therefore, searching for remnants of the ancient world can be both an opportunity and a danger, as the depths are inhabited by enormous sea monsters.

I thought a lot about how to do this part, so I stopped to think.

In fights, if you damage a sea monster with anything, it will instinctively unleash heart-rending shrieks, howls, and screams as it tries to hit you or defend itself.

They can flee; they're intelligent and won't stay still. If they sense they're about to die, they hide to avoid being attacked and wait for the right moment to launch a surprise attack.

The appearance of most sea monsters is horrifying and terrifying. Some are grotesque, some enormous, and would freeze with fear anyone without experience.

One curious thing is that monsters get burned by water. They don't literally burst into flames, but they do begin to feel an intense, scorching heat that boils them. That's why monsters usually don't come out during the day and stay hidden in the depths, where the light doesn't reach.

When 6 o'clock strikes, the sun begins to set, and you must remain silent with Rita. You're used to it by now, so it's no problem. But don't make any noise, or you might end up not sleeping all night.

You can't make mistakes, there are no second chances, don't wait for something good to happen by a miracle, either everything goes well or everything goes terribly wrong.

Who said we have to give up?
It's been quite a few years since the world was covered in water, that's true. But who's to say that at some point the place you find yourself clinging to won't be a ship, or a ruined building? And what if land might one day reappear? A fertile island...

People dream of it, that at some point, by some miracle, an island will appear, a sign of hope.
