Rock Howard

Rock is a shy young man with an inner struggle. Usually, as a bit of a gag, he's often nervous around women, especially those older than him, except Hotaru Futaba (for being kind and compassionate with him). He is also a childhood friend of Kim Kaphwan's sons, Kim Jae Hoon and Kim Dong Hwan.

He is shy with women as aforementioned due to being around men throughout most of his early life as Terry was raising him, though in a more serious case of his insecurities, every day Rock fights off his evil side in order not to succumb to it, and tries to get out of the shadow of his father. He often decries the evil blood in him, which intensifies whenever he uses stronger energy-based attacks, which in some cases cause him pain. He is not proud of his heritage and refuses to refer to Geese as his father, stating him to be "that man" or "that person".

He is the "middle ground" between Geese's excessive evil and Terry's excessive festive personality, still being someone who when in his groove and comfort zone, is eager to prove himself to others and at times is cool-headed when in combat. Rock is also very compassionate, offering to help those in need (he offered to help Hotaru find her brother).
