Fortis931, ステイル＝マグヌス

A sorcerer from Necessarius goes by the name Fortis931. He is a heavy smoker who believes a world without nicotine would be unbearable. His specialty involves using flames, which he can use to wield a flame sword or summon Innocentius, a 3000-degree Celsius fire known as the "King of Witch Hunters." Despite his intimidating appearance, Fortis931 is only fourteen years old and physically weak. Although he has a bad temper, he is kind at heart and deeply cares for Index. The loss of her memories after failing to save her life was his greatest regret. When he discovers that the Church had lied about Index's condition, Fortis931 decides to disregard orders and allow her to live freely.
