Ninja vs. Gokudo

For centuries, two underground tribes have been at war, ninjas who «clean» the world from the shadows and gokudo who gather outcasts and build power through crime. In modern Tokyo, Shinoha Tanaka and Kiwami Kimura meet by pure chance and click over the most harmless thing imaginable, anime fandom and everyday hobbies. Neither of them knows the other is a sworn enemy. That small friendship feels real, which makes it dangerous. As the old conflict flares up around them, their double lives start colliding with their normal faces, and every new incident forces them to choose whether the bond they built is worth betraying their own side. The story keeps tightening the screws until «just don’t find out» stops being possible and the feud demands blood again.
