Another Ninja Slayer?

Recently rumors have been swirling all across Neo Saitama of Ninja Slayer's death. But deep within the darkest crevices of the underworld there is word of another ninja hunter! Is this masked man a ninja? Is he a renegade yakuza? Or could he be a cyborg developed by the NSPD? No one really knows who the man behind the Tengu nose really is...or his purpose.
