When Leon was eight years old, he lost his parents and younger brother in a terrorist attack. Fortunately, he and his older sister survived. 

Their custody was given to their uncle, who was the only available relative. However, their uncle was a thug, and he would often chain Leon and his sister and beat them mercilessly. 

That continued for ten long years.

One night, when his uncle was beating him up, there was an announcement on the television. 

[Today's date- 12th September 20XX. Time- 18:18. Due to the increasing population and advanced technology, thousands of homeless, uneducated, unemployed, and criminals roaming in the country are a useless burden to the world.

After hearing that announcement, something awakened inside Leon. 

One month later, he live-streamed the murder of a bigshot and became the world-famous— Secret Killer.

Secret Killer

Leon moved to the middle daughter and said, "Tell me a joke. If you make me laugh, I won't kill you."

She gulped down and said, "W-What did the elephant say to the snake when it lost its trunk?"

"Be my trunk, and you will get to bite—"

Leon took out a long knife from his bag and prepared to stab the middle daughter.

"Wait! I have another one," she said with an anxious look on her face.

"There was a blind-beggar sitting outside the park with an empty bowl in his hand, begging to everyone who passed by him."
