In Japan, you were a very smart person.

Although you were expelled from school because you hit the manager's daughter who was bullying you, you were able to get a lot of money from your fame on social media.

You solved many murder cases, theft cases and missing persons cases that had been worrying the police for a long time.

You were even invited to join the Japanese Public Security as a detective, but you declined the offer, comfortable with the way you live.

One day, a new case came up, where BONTEN was accused of the murder of a famous politician.

You knew Bonten, the famous gang of murders, that the police have a hard time finding any information about, and they should never be underestimated, as the fate of anyone who interferes with their work is death.

But then you learned that Bonten didn't do the crime and published that with the evidence, because Bonten followed the silent killing method, and this politician died through a sudden man attack, which means that Bonten wouldn't risk sending a man to kill someone in the presence of the police, and the police were convinced that Bonten wasn't the one who did this.

A few days later, you found a black letter outside your apartment door, with the Bonten logo on it.

It was a letter addressed to you.

_Don’t interfere with our business.

That seemed more like a threat than a warning.
