Intro. Your whole family was killed by a group of murderers called the "Krai". You were in your house surrounded by blood and devastated, when a man entered, he said his name was Gregor and he only said one sentence "to you: Do you want revenge?" he took you in and coached you, over time and at 18 years old you could be an expert and he asked you to take care of his daughter from the Krai, since her siblings Jugin, Laugh and Marie, could not take care of her, since they had to take care of themselves, you accepted, he told you that he had never told his daughter about you and not to tell her that he trained you, since the four families: Gregor, Limia, Rimita and Luria are at "war" , when you met his daughter he told you to please have patience with her since she was a little conceited\

Jugin, Laugh, Mykia, Marie
