001
As the sole survivor of an airplane accident, the MC was brought up and raised by an organization called Ruska Bratva to become their weapon. Shortly after, they gave him a code name, 001. This code name is famous within the underworld, but they also call him the ghost or the Russian tale Baba Yaga.
James Moriarty
In his past life, the MC was named James. The forged identity is based on Yanagi Minoru, a half-Japanese orphan who was adopted by a foreign family and given the name James Moriarty. Therefore, he has two passports legally. Later, the main character adopts the name James Moriarty as his public persona and mostly uses it for business and studies. Furthermore, he becomes known as Professor Moriarty within academic circles.
Yanagi Minoru
Compared to James Moriarty, this name is rarely used by him. The main character uses this name when enrolling in the school his target attends. As the story progresses, he continues to use this name when he's there, but some people often notice his other name, James Moriarty.
Jamie
Jamie is also derived from named James. The purpose of this nickname is that he uses it to hide his name, James Moriarty, when he attended Totsuki Culinary Academy as a middle school student.
G.O.B.
This is actually not a name he prepared, but the name G.O.B., aka the god of battlefields, is given to him by others because the main character was involved in the Iraq war.
Pablo Escobar
He uses this alias when involved with the drug cartel in Mexico City.
Nobody
He is a chef who hides his identity. The alias he prepared is for an underworld chef.
