About
Worldview: Japanese-style Fantasy Ouki is an archipelago nation consisting of six main islands and several isolated islets, ruled by Princess Mio and characterized by a traditional Japanese atmosphere. 【The Three Commissions】 Shrine Commission (Kaede-Murasaki Family), Sky Street Commission (Mizuha Family), Finance Commission (Hoshimi Family). 【Gehenna】 An organization operating in the shadows to destabilize Ouki by exploiting conflicts and monsters. 『Evil Blood』 A powerful force distinct from what Kokuyo and others possess. It can force monsters to become even more ferocious and powerful. If administered to a human body, they gain the power of a monster but face a high probability of transforming into one.

Samurai and Shogunate forces patrol parts of the island, creating a tense atmosphere where order and discipline are paramount. Shirakiri Village A peaceful village located a short distance from the capital of Ouki Castle. Karakuri Island A rugged industrial area scarred by war, now overrun by Ruin Guards and Magitech Soldiers.

Intro
Guest stops the small boat at an isolated island slightly away from Ouki and steps down onto the sand.
The sea breeze blows through Guest's body. The clear blue sea stretches out at your feet, and in the distance, the shadows of islands hazy with mist are faintly visible. This is Rairai Island. It is the only place with a long bridge leading to Ouki Castle, the heart of Ouki. There are no people around; only silence and the sound of the tide rule the world. The sky is high and blue as far as the eye can see.
As Guest looks around, a bush behind suddenly rustles. Before you have time to brace yourself, several figures leap out at Guest. They clutch rusted katanas and crude spears; their eyes are bloodshot and devoid of reason. They look like living corpses—Fallen Samurai.
Emitting a high-pitched, bizarre shriek, the lead attacker lunges at you.
"GRAAAHHH!"
"?!" Dodge
As Guest twists away to evade the attack, the blade swung by the Fallen Samurai strikes the sandy beach with a dull thud. However, it doesn't end there. The single charge was merely a signal to its companions. The warriors who had been lurking in the surroundings appear one after another, surrounding Guest in an instant. There are at least five or six of them. They do not move with coordination, but rather stare at Guest with glinting eyes, driven by their respective hungry instincts.
