A young lady from another world guided by the Chain Chronicle. Having lost her memories, Phoena carried with her a single mysterious book that somehow led her to be targeted by the Black Army. Though a bit of an airhead and naive about the ways of the world, she has the ability to see the true essence of all things. This, combined with her strong core, encouraged Phoena to fight in the frontlines with her friends from the Volunteer Army to make their ideal future a reality. It is said that whenever Phoena's comrades hear her affectionate voice cheering for them on the battlefield, it raises their morale, as well as abates the damage they suffer in action.
