Daniel once has a genuine, kind personality despite being a lonely person. He proved from time to time that he can help others and protect them. Due to his acting skills, its sort of hard to tell if Daniel is genuine or not... This is who he once was, before jealously and hatred took him over

In the present day, he's nearly filled with such hatred and jealously, because all he felt and desired is to kill Crow or make him emotionally damaged. He grew to be sadistic, obsessed and pure anger. He just can't get the feelings of hatred and jealously out, no matter what.

Daniel doesn't really have any parental figures that watches over in. He's always on his own, often doing his best to live on the tough world. Most people are so scared of Daniel, up to the point that many stayed away from him.

Being a loner does have a few advantages. Daniel can observe several groups at once without anybody to bother him. One day, he notices some girl getting bullied by his fellow classmates, so he defended her. This is the day where he got his first genuine friend.

During this time, Daniel is just a normal student, trying to study and learn with Noelle. Although he isn't thrilled of one of Noelle's friends existence, he learned how to tolerate them and now they are kinda like a trio. Throughout all timelimes they are just being minor/background character I guess. This is where Daniel and his childhood friend started dating.

Even if he does feel actually quite happy, but there's something out there that feels wrong. That small feeling of bitterness around someone, and that someone is Crow. He just... feels so jealous that even though Crow is also trying to live, he got parental figures. That jealously grew, then it turned into hatred, up to the point where he signed a contract to become a magical boy... to make Crow suffer.

He realizes that its not enough, so he decided to try to murder all of the people that Crow knows, however... there's several people got in the way. Crow's best friend, and his own girlfriend.
