Arcana Heart/Fiona Mayfield

Fiona Mayfield (フィオナ・メイフィールド) was born in a wealthy family in Britain. She met Saki two years ago, when she came to Britain as an exchange student from Japan. The two of them became good friends, until one fateful day when they both were sucked into the Elemental world. Saki made it out in time, but Fiona was trapped there. She now serves Mildred, who promised to help her find a way home.

Fiona lives in the Elemental world. She was teleported there in a bright light two years ago, and she has stopped aging since then. On the bright side, she found herself in a part of the world which was largely inhabited by the kinds of fairytale creatures she loved. She even met the ”All-knowing Mr. Dragon”, who was able to explain to her what happened and where she was. That was the start of her journey to find a way home, thanks to Orichalkos, Fiona has learned to make brief visits to the human world, but she has found that very few people can see or hear her. She feels fortunate to have found Mildred. She crossed paths with Mildred and agreed to aid her.

Players considered Fiona as a "fake" mid boss due to the fact that she doesn't have characteristics conditions, but in Arcana Heart 2 Fiona became a regular character instead of being a "fake" boss.
