"No. VII SAIX
Second in command who longs for the heart he does not have. Only the moon breaks his icy calm.
Weapon: Claymore " - Opening
"The Organization's No. VII. Usually cool and calm, he turns into a berserker when he grips his giant blade in combat.
Dodge his attacks as you watch for a rare opening. After taking damage, he will revert to his normal self, making him more susceptible to attack. Finish him quickly." - Enemy Journal
