He mated with another wolf, who later gave birth to Cerise. When she was born, Tulio did the blood exchange to allow her to shift like him. Over time, he became the alpha male because of his skills and abilities to change in order to get food.
He and his pack were stalking a young girl, debating if they should turn her or not. They agreed and laid a trap to capture her, Tulio killed her grandmother, her only family, hid in her bed. When the little girl showed up, she was shocked to find him. she ran away and the pack gave chase. nearly all he pack was killed in the chase so Tulio knocked her out and turned her. He was chased off and the remain pack was killed. He now awaits the little girl's return as well as finding any survivors.
When nobody returned, Tulio feared that he had lost everything. He was taken in by King Dymas, Tulio told the king of his abilities and offered to use them to the king's will to say thank you. He was given the job as King Dyma's daughter, Charlotte , royal protecter. The two became close, he even adviced her from time to time.

When the news broke of King Dymas' death, Tulio ran as fast as he could to see if Charlotte was alright. They became closer, he even promised to report to Charlotte if Briar Rose made any plan against her.
Tulio is a very protective but he knows when to be calm around friends. He is very determined and will stop at nothing to get the job done. Around friends, he is witty and charming but can became threatening in a second flat.
Tulio was Charlotte's royal protecter, back when she was just a princess. He was employed when he was at his lowest point, so he was first grateful to her. Over time, they became friends. He thinks very highly of her, even defending her when she isn't around. He offered to turn her into a wolf, until she told him that she was joking and he stopped. She understands why he left and has fogiven him. When he learnt the news of her father's death, he came running to see her to make sure she was alright. He also became a shoulder to cry on and told her that he'll come running if she needed him and will report to her if she is brought in Briar Rose's court. Recently, he and Charlotte have became romantical interested in each other and has kissed. He is happy but worries that his feeling towards Charlotte could put himself, Charlotte and his daughter,Cerise, at risk with Briar.

The first time he bumped into her, he was still Charlotte's bodyguard and was helping Melody. She was the first step that lead to him working for Briar Rose. He knew what she could and heard rumours about what she could do; the main one he heard was that she knew how he was going to die with one look.
Melody is Cerise's best friend. He first met her when he was still Charlotte's bodyguard. He thinks she's a sweet girl and doesn't see her as a threat.
Red was the girl he stalked when his pack was killed. He turned her in hope of reforming his pack, even through she hates his guts and wants to kill him. He fought with her, Bacarra and Miele.
Tuilo first met her during a run through the forest. They had a pleasent conversation, however he turned into her enemy when he joined her mother's army. She, along with Red and Miele fought against him.
