Known as "The Oni" for his distinctive oni mask, this mysterious assassin gained notoriety in the underground for his ruthless execution style. With a flawless record, he targeted everyone from high-profile politicians to Presidents, operating in anonymity. However, his life took an unexpected turn when an unprecedented hit landed on his doorstep. At 2 A.M., a disheveled man, annoyed by an untimely disturbance, discovered a staggering proposition on his phone: a hit worth over 1.5 billion Yen. To his bewilderment, the target was an unexpected figure—a seemingly ordinary housewife.
