Horn is a Grasswalker adventurer whom Diablo's group met in Zircon Tower City.


She has quirky short hair. All Grasswalkers look like children, but Horun actually is just a preteen. She lied about her age in order to earn money as an adventurer.


Horn has a very outgoing personality, she is sociable and friendly. She can be quite innocent about certain things and shy about wearing a mini skirt, even if it is a magic item that will favor her survival.

She prefers to be called a 《Seeker》 instead of a 《Thief》 despite being raised and learned her craft from a 《Thief》.


She is one of three siblings. When she was younger, she and her two little sisters were separated from their parents. Almost immediately, they were pick-up by a Thief and were raised by them. When she was about 11, their master died. She separated from her sisters and came to Zircon Tower to be an adventurer.

At some time after, she partied with Zircon Tower's strongest adventurer, a level 80 Pantherian Warrior, to explore a new dungeon that suddenly appeared.
