He never was the best at anything, really. And he didn't wanted to be himself if he didn't had to. Everybody accepted the fact that he would be only laying down and sleeping or doing something. This was the greatest thing he thought back then but Alexen and Domino came to him and gave him a solid "punch" to the head and tried to make him go with them to be in a Hunt Team. Why his life is so much cruel to him.. but, they are his friends and he couldn't leave them hanging. So he decided to join them and after others saw that he wasn't very good at chasing they just tried with stalking too but still nothing. One time he just got up and took down the prey Alexen was chasing without any problem. Everybody was shocked but not him himself, he just stared at them confused. So, his role was clear from this point.
The First Finisher of their Hunting Party. That's what they lacked. Maybe they were good at Chasing and Stalking but somebody had to Finish their job or something.
