Elison keeps his background to himself. But everyone knows he grew up in the house. Its been past down generation after generation. Elison never had a choice he had to take over the family job. He grew up very close to his baby brother, Ren. He is also rather close to Junhyung and Brock. Both of them watch out for Chihoon. They don't want Elison to kill another one. Elison anger problem has always caused him problems. Problems Ren, Brock and Junhyung had to take care. When Elison was younger a Master got ticked off at Ren and beat him. Elison lost it, he beat the master until his face was mush. Ever since then Elison has had the hardest time stopping once he has started. Brock is normally forced to over power him and hold him down until he stops kicking. 

Chihoon is Elison's everything, but that does not stop him from beating the boy. Chihoon tends to get most of Elison's beatings. But Elison is always sorry. He loves him more then anything in the world. Its strongly at warned to stay far away from Chihoon unless you have a death wish.
