Esmeralda

Esmeralda was an slave worker for a farmer villager in Death Queen Island. She was saved by Ikki once he saw her being whipped by her owner. From that day they started to see each other frequently at an unusual place where flowers grows in the wasteland of Death Queen.

In the anime adaptation Esmeralda was Guilty's daughter who cares of Ikki after training sessions by sneaking in the dungeon where he was resting. Her death was the same like her manga counterpart.
