Hero is a young girl who became a platinum-ranked adventurer after defeating the Demon Lord. Along with her party, she battles the Demon Lord's forces and other powerful threats. Hero has dark cyan-colored eyes and long black hair, with a single strand pointed upward, decorated with a light blue headband with bows at the ends. She wears white robes along with silver chest-plate armor, gloves and boots. Hero's most noteworthy feature is that she is armed with a large holy sword that indicates her status as a hero. In her "Spear Girl" rookie disguise, she wears green garbs and wields a spear as she is emulating Female Warrior. In the anime and Year One manga, she has dark red hair with apricot-colored eyes, and wears a yellow headband. Hero is a brave, outgoing yet impulsive tomboy, shown when she deliberately gave away her party's location in favor of a bold introduction. Though she may come off as arrogant, her confidence is backed up by her extraordinary abilities and accomplishments, including the recent slaying of the Demon Lord, numerous members of the Evil Sect and other powerful Non-Prayer Characters. In spite of these traits, Hero is a friendly individual towards her allies as well as fellow strangers. She is also wise enough to recognize Goblins as threatening and vicious creatures.
