Arsène Lupin
Lupin was born in 1874. His father was a gymnastics teacher and taught him boxing and fencing which later became Lupin's attacking specialties. He was raised by a nanny Victoire, and their relationship lasted until the end of the series. His parents got divorced, and his mother started working for a relative who is fairly arrogant. In the house of the relative, Lupin robs a necklace as revenge. Until eighteen, he had been learning law, medicine, acting, and martial arts. His journey as a thief starts at age eighteen.
