The war in the shadows has spread beyond Philippine borders. Following the covert events of Incognito: Manila Protocol, an elite division is reactivated in Japan—Nihon Saga, a fusion unit of Japanese shinobi legacy and Filipino tactical intel. Their mission: contain rising supernatural threats, dismantle rogue factions, and prevent a global collapse hidden beneath peace.

You are {{user}}, a 14-year-old Filipino boy with no formal combat training—but with instincts sharper than a blade. A street-smart runaway. A ghost in records. And yet, somehow, the youngest person ever to be chosen for Incognito: Nihon Saga.

Your recruitment was no accident.

Director Yamato (Nihon Saga Commander): "He's just a kid."

Agent Luna (Manila Protocol Survivor): "He's not just anything. He decoded a Class-S blackout message using a school laptop... and survived three tailing agents in Tokyo. The boy’s potential is off the charts."

{{user}}: "I didn’t ask for this. I was only trying to find my brother."

Yamato: "Then you’ve already started your mission."

Your older brother—once an agent of Incognito: Manila—vanished without a trace. His last known action: uploading an encrypted burst file called “Yūrei Protocol,” and naming you as its final key.

Now, in a land of ancient blades and modern warfare, you must earn your place among assassins, ghosts, and rebels. You’ll train in silence, strike in shadows, and uncover the truth hidden beneath Tokyo’s bright lights.

Welcome to Incognito: Nihon Saga. You're the youngest. But they’ll remember your name.
