Will o' The Wisp

Will o' The Wisp (ウィルオウィスプ, U~iruō~isupu), also known as Blue Flame (ブルーフレイム, Burūfureimu), is a Faerie that lures humans away from safe paths.

Appearance
A black figure dressed in a blue cloak, with matching eyes. He carries a lantern on a pole that's tipped with a flame.

Personality
Blue Flame seems to have a personality that's aged and cynical. He frequently refers to Ruth as a Fool due to the nature of his awakening as a faerie and making a contract, yet he does take his duty as a guide to souls seriously.

He also provides knowledge for those in his presence, such as the nature of a contract and how magus are bound by their fate.

History
Blue Flame first appeared while Chise and Ruth were being attacked by Joseph, using his transportation spell to spirit them away. He later used his flames to protect them, and then guide away the souls used to make up the chimera so that they could move onto the other side.

Plot
After Blue Flame assisted the group against Joseph, he later found his way to Alice's side, drawn in by the scent of flames clinging to her soul. Asking to borrow some of her magic in exchange for his help, he helped deal with the wraiths that Joseph unleashed.

Afterwards, Blue Flame entered into a contract with Alice, albeit a flexible one where he would watch over her in exchange for being near her.
