The Criminal - Season 1

A masked man disrupts a peaceful afternoon, stabbing everyone in sight. The police later find the suspect dead, making it an open-and-shut case. However, Detective Soma has his misgivings when Shuji, the lone survivor, gets attacked again. Told to survive just ten more days by a mysterious man, Shuji is forced to depend on Soma as they are pushed into a shadowy world neither are prepared for.

Nakasako is basking in the joy of turning his company's latest baby food product into a big hit. Or he would have, if he had not discovered the cause of the new face-deforming disease. When food manufacturer Titus Foods chooses to protect itself over the innocent children, Nakasako gets dragged into a conspiracy more sinister than anything he could ever imagine.

Nine days before the mass stabbing, Nakasako's accomplice, Mazaki, settles into a hotel to begin his plans. However, a theft throws everything awry, leading him and a couple of innocent hotel employees down a deadly path. In the present, Shuji accidentally finds a clue that leads to the identity of the mysterious man.

After learning Nakasako's identity, Shuji's memory leads his team to Mazaki, who has vanished; just as the case hits a wall, Yarimizu finds a clue tying Mazaki to Titus Foods and the stabbings.

When Shuji falls into a deadly trap, Soma and Yarimizu discover his painful past, forcing Soma to face his own demons; the trio uncovers even deeper secrets lurking in the shadows.

Public outcry grows as Mazaki's accusation against Titus Foods is revealed. Meanwhile, Soma, Shuji and Yarimizu finally make contact with Nakasako after confirming Mazaki's true goal.

Determined to honour the sacrifices of Mazaki and Nakasako, Yarimizu, Shuji and Soma vow to persist in their struggle. They set out on a perilous quest to uncover the corrupt dealings of those in power.
