Anime Like Ninja Ryuukenden
A ninja stumbles into a conspiracy that doesn't care about his code. What starts as a simple rescue spirals into something uglier: corporate greed, a cure someone wants buried, and a kid trapped in the middle of it all. The OVA doesn't waste time on origin stories or philosophical debates about honor. It moves like a bullet, trades your investment in who Ryu is for what he's willing to do, and ends before you can catch your breath.
SYNOPSIS
A ninja warrior named Ryu surfaces in New York City after a violent midnight encounter leaves questions about a mysterious corporation called Friedman. When the company's charismatic doctor announces a revolutionary cancer cure without offering any details, journalist Sarah smells a cover-up and recruits her colleagues to dig deeper. Their investigation crosses paths with Ryu when they investigate Friedman's residence, where a child's desperate cries reveal the horrifying truth: the doctor is running illegal experiments on human subjects. What begins as a straightforward exposé unravels into something far darker and more dangerous. The experiments appear connected to ancient supernatural forces Ryu thought he'd already defeated, forcing him to confront a threat that bridges his past as a warrior and the present-day conspiracy unfolding around them. Sarah and her team find themselves caught between corporate greed, forbidden science, and the resurrection of powers that should have stayed buried. Together, they race to stop Friedman before his research unleashes something catastrophic on the city.
