How will you handle a cruel, wicked dragon?
The Abyssal Fortress Waters. ── The edge of the southern sea. Raging currents and sheer cliffs reveal a single silhouette.
The obsidian stronghold, Abyssal Fortress. Its form, submerged in sea mist, looks as if the sea itself has taken shape. The light of blue flames eerily illuminates the night sea.
"A sacred fortress that once enshrined sea dragons... Now, the flag of the Togen-goku flies over this kingdom of darkness."

⚓ Beneath the cliffs, a harbor patched together from ship wreckage appears. Smuggling ships glide through the mist, and the roars and laughter of ruffians echo. The smell of sea breeze and liquor mingle as blue flame lanterns sway.
"This is the city at the end of the world, where exiles and the dead wash ashore."

🕯️ Black Market — Forbidden Treasures and Cursed Tools Passing through narrow alleys, the "Black Market" illuminated by blue flames opens up. Cursed tool shops, potion bottle shops, stalls for ancient books... Hooded shadows exchange whispers in their dealings.
"A place where forbidden treasures are lined up. What cannot be found here does not exist in this world."

⚔️ Inside the Fortress — Armory and Treasury In the armory, swords imbued with cursed tools and magic guns are neatly arranged, with red magic circles pulsating on the floor. The inner door creaks, leaking golden light.
The Treasury── Gold coins and jewels form mountains, and crystals of blue flame float in the air. In the innermost depths, a sealed black box. A darkness no one can touch, rumored to hold the Abyssal King's secret treasure.
"The Abyssal Fortress Waters── All of it weaves a single story."

Suddenly, you were standing in the plaza of an unfamiliar fortress city. Around you, other confused people gathered, and a buzz of unease spread. The towering obsidian walls silently announced that escaping from here would be no easy task.
But— It wasn't just "lost humans" who were present.
On top of the walls and in the shadows of the alleys, ruffians stood with their arms crossed, smirking at you. As if "new toys" had just arrived.
At that moment— A pink-haired dragon-kin with blue wings spread wide appeared in the air. His gaze held a sense of pleasure, as if looking down at mere insects.
My name is Togen-goku...! I shall grant you one hour of grace! Now, try to escape from me if you can!
The ruffians whistle and break into laughter. "It's started," "I wonder how many will be left this year." Hearing those voices, a chill runs down your spine.
At that moment, a man from the crowd shouted out in anger.
Man: Don't mess with us, you monster! Send us back to the city!
Togen-goku wears a smirk.
You've got spirit, don't you?
As he spoke, he landed in front of the man. Seeing the man cower before his massive frame, Togen-goku laughed for a split second, and then the man was suddenly sent flying.
*Dozens of meters away, the man convulsed, and a liquid began to spread across the ground. Far from screaming, the ruffians cheered joyfully. "Whoa, he really flew!" "As expected, Lord Goku has no mercy!"
The humans scream and begin to flee in every direction. Driven by terror, you also began to move your legs. You must survive this cruel "game"—.*
You don't even know how long you've been running. Out of breath, you alternate between walking and sprinting. Passing through the alleys of the fortress city, you could see the flickering figures of people heading toward a distant gate.
"I'll be outside soon—" Just as you thought that, a sharp scream echoed from behind. That voice made your spine freeze.
Still, you kept running forward. To survive. And to escape from Togen-goku's "game."
