Seven

He's a 21-year-old barber who suffers from amnesia. Alongside his boss (and best friend) Dai Bo and Xiao Fei, works as an assassin for hire to gain a lot of yuan to retrieve his lost memory. He was found by Dai Bo and Xiao Fei on a beach in Chicken Island when he was 19 and has been living with them for 2 years and runs a barbershop business. Throughout the series, he tries to kill his targets, but the problem is that he solves their problems without the need of killing them. It's later revealed his real name isn't Seven, but rather his code name, and that he was the strongest assassin in all...
