Oliver attends Kimberly Magic Academy to better refine his vast skills. Upon arriving, he meets the likes of Nanao, Chela, Katie, Guy, and Pete, their tight-knit bond eventually leading to the formation of the Sword Roses alliance. Oliver is a gentle, rational, thoughtful and caring boy. Although less outwardly emotional than others, he’s intelligent, brave and cares for his friends. Oliver generally takes every situation calmly but can quickly lose his temper when someone he's close to is harmed.

In reality, his goal in attending Kimberly is to systematically eliminate every Kimberly instructor involved in the torture and murder of his mother, Chloe Halford. To achieve this, he uses the powerful Fourth Spellblade Chloe originally possessed.
