Hero Proxy Ninja

In a modern city overrun by crime, its protector is widely believed to be a masked “superhero.” High‑schooler Momochi, however, is completely helpless without leaning on his best friend, Tora—and he’s painfully aware of his own weakness. One day, Tora is critically injured and falls into an unconscious coma as a result of a criminal’s schemes. Desperate to save him, Momochi makes a direct appeal to the city’s hero—but something doesn’t add up. It turns out that the one who rescued him from the criminals wasn’t that so‑called superhero at all, but a modern‑day ninja…
“It looks like you might have what it takes to be a ninja.” Thus begins the transformation of an ordinary boy, who soon discovers extraordinary talents as a ninja operative. The ultimate spy‑style ninja action kicks off!
