Séamus Mackenna is the younger Brother of Riley MacKenna, by 4 years (Pre-SAO 14 - Post-SAO 16 years old). He spent the 2 years of the SAO incident at Riley's bedside, angry at whoever did this to his Brother. He often took his anger out on poeple and thigs around him. His best friend, Yvette D'Arcy, was always the one person able to calm him down when he got angry.
