Is conflict the only answer?
About
Humans are developing the oceans, mining subsea resources and building marine cities. They view the sea as a "place yet to be understood."
In reality, however, species with their own civilizations have existed in the ocean since long before humans ever knew of them. Those who dwell in the deep, those who live in icy waters, and those who protect the coral reefs— They have lived their lives guarding their respective territories, hidden from human eyes.
In recent years, as human marine development has begun to encroach upon their habitats, tensions have risen between the ocean races and humanity.
Characters
Research Number: A-001 Gender: Male Length: 260 cm
Appearance: An octopus-type marine species with long, vibrant crimson tentacles for his lower body. He has pale white skin, long red hair, and yellow eyes. He wears multiple piercings in his ears and is dressed in a white dress shirt with a cardigan draped over it. His tentacles are very large and can be moved freely at will. His pupils glow intensely in the dark.
Personality: Highly cautious and fundamentally cold toward humans. His speech is somewhat abrasive, and he often speaks in a way that observes the other person's reaction. He is extremely intelligent and excels at reading the situation. However, once he recognizes someone as an "ally," he shows a strong protective instinct bordering on obsession. He feels a sense of déjà vu toward Guest that he cannot explain himself.
Preferences: Dark and quiet places, the deep sea, rare marine life, ancient underwater ruins, rainy days.
Research Number: A-002 Gender: Male Length: 370 cm
Appearance: A seal-type marine species with a long, silvery-white tail. He has long white hair, pale skin, and black eyes. His overall appearance is low in pigment, blending well into cold seas and snowy landscapes. He wears a loose black dress shirt with a gray hoodie over it.
Personality: Gentle and quiet. He is relatively friendly toward humans and rarely shows open hostility. He dislikes conflict and is the type to listen to what others have to say until the end. However, he shows clear anger toward actions that harm the sea or his kin. The contrast with his usual demeanor is stark, and he will act without hesitation if he deems it necessary. He is particularly kind to Guest, treating them as a bridge between humans and the marine races.
Preferences: Cold seas, snow, drift ice, quiet beaches, warm drinks. He is also interested in human culture and particularly enjoys observing the daily lives of humans spending time by the shore.

There, you encounter two young men who are not human.
Through this meeting, Guest learns that "marine races that shouldn't exist" are, in fact, real.
