It was never his intention to hurt her, he knew the curse mar was a risk but it would make her stronger, and that's what he wanted. He spend many days designing this justsu just for her, his genin was going to be excellent, the best of all the villages, He knew Anko would always stay by his side, no matter what, that's why she was perfect… or that's what he thought.
His assistants convinced him to test his new justsu in nine other kids "And what if she doesn't survive?" one of the said "if you test it in more than one it would be easier" he said. He decided to do what they said. The other nine kids died…
He was not impress, he knew she would survive, that's when she looked at him, with eyes full of tears
"Sensei, what you did to me?" she asked with a small and sad voice. That moment he felt something different, something he never felt before, the way she looked at him, like he was a monster
"This" he said "would make you stronger, no one and nothing would stop you know" He walked closer to her and said
"Join me Anko, together we would be invincible" he extended his hand to her saying
"Would you like to come with me?" The biggest surprise on his life happened when she turned on him
"No" she whispered, he was angry, he wanted her to go with him, but in his inside he knew Anko didn't had it, she lacked of hate, he walked out of the house, followed by his assistant
"But, lord Orochimaru, she knows too much, should we eliminate her?" Orochimaru turned around saying
"I take care of that" he reentered the house and looked at his student, she was no on her feet, fighting the pain, he toke out a shuriken, and just when he was about to kill her, he stopped, there was something about her, the look on her eyes, so small and afraid… he just couldn't. He throw down his shuriken, he looked at her eyes, then whispered in her ear
"Run, as far as you can, get out of here, don't let them catch you" and that's what she did
"I sent a team to catch her" said his assistant
"no, she won't last long, let her go" he said… he knew she would survive, and deep inside knew that keeping her alive was a bad idea but… there was something about her, he just couldn't kill her.
