Angelica

Seen as a knight with flowing golden hair and blue eyes. Is saved by Haruka.

Angelica is the name of the Level 100 Dungeon Emporer Haruka fought with. Haruka used his skill "Servitude" on to set her free from a curse that had been placed upon her. When she was cursed she had appeared as a skeleton in a black shroud, but her appearance changes upon obtaining level 100 armor named "Living Armor." It is cursed pure silver amor that binds to the wearer as if it become their own flesh. Resulting from this, she is not a skeleton anymore, but is now a 17 year old girl.

Due to her being saved by Haruka, she is indebted and is also seemingly attracted to him
