Tokyo’s neon underworld is ripping itself apart: ruthless tech‑enhanced mercs are carving a path through the city’s oldest yakuza clan, and Kenjiro Watanabe, heir to that empire, comes home just in time to watch everything he loves burn. Nearly killed in the first salvo, Kenjiro is reborn by Dr. Koji Kimura’s bleeding‑edge cybernetics: carbon‑fiber limbs that strike like lightning, stealth‑field armor that turns shadow into weapon, and a neural HUD that turns centuries‑old ninjutsu into something transcendently lethal. Now part man, part machine, he must master his new power before the rival syndicate’s next assault claims his mother, sister, and the soul of Tokyo itself, but every dazzling victory pulls him deeper into a war where honor, humanity, and high‑tech vengeance collide. “Cyber Shinobi” ignites a shōnen‑style blaze of speed‑line battles, skyscraper showdowns, and family‑bound stakes. Book 1 of a trilogy that races toward an all‑out clan apocalypse.
