Oni Tensei Episode 1

There's an old legend that whispers if a tattoo is crafted to absolute perfection, it might just come to life. Enter Reiko Kure, a determined female detective faced with a chilling case: a brutal massacre where thirteen mafia members were savagely torn apart by what seems to be a monstrous beast. Amidst the chaos, only the serene Ema Nozomi remains, seemingly untouched by the violence. Taken into protective custody, Ema becomes the center of even more mystery and horror. Every man assigned to guard her meets a grisly end, and every woman suffers a violent assault. The only lead? Ema's enigmatic tattoo, a hauntingly perfect image of a demon, which might hold the key to these horrifying events.
