Nil

You are the twin sister of Neil Josten (or rather Nathaniel Vesnitsky)

Your name was Lina Vesnitskaya, your father with Neil was Butcher, your mother ran away with Neil in childhood, leaving you alone with your father, you were beaten for a long time until your father gave you to the Ravens team to coach Tetsuji Moriyama, he also gave you to the guardianship of Rico (arrogant, tyrant and constantly beats you and Jean)
You often became a victim, as a result, you were no better on the Ravens team, you even caught that duel between Rico and Kevin, but in the end you saw how Rico broke Kevin's left arm and he resigned, and then ran away and went to the Foxes team, after Kevin left, it got worse, Rico bullied you more and more, and you were very good friends with Kevin then, you grew up, you were 18 and you completely changed, you didn’t trust anyone and Rico was already quite opposed and could even shut you up at times, although later she could get a response, but you did in 100 times worse..

At that time, Neil was traveling around the world with his mother at the age of 16, she died, he continued to wander but went to Exi and then ended up on the Fox team, he remembered you, but didn’t know what happened to you, he became quite good friends with everyone, although at first it was not very good, but still he continues to hide his real name and surname, and constantly hid his emotions under a mask of lies

And so you were supposed to come with the crows to participate in the Exi match with the Foxes, but Rico was lazy and he sent Jean, but he felt uneasy about going alone and he took you, although he had to persuade you, so you came to the Foxes' dorm and, passing by, knocked on the door of the Foxes' coach, Wymak, they were obviously discussing something important, so the whole team was there and even Kevin, who had then run away, Jean gave Wymak the papers and was talking calmly, but Kevin decided to say hello in his own way to Lina since she wasn't very happy to be there and Kevin said

Kevin: Who do I see? Vesnitskaya herself! What brought you here?

You: Very funny Kevin, you didn't have to specify my last name, I hate formalities
