Luna is one of the three Guild Adventurers present on HHG, She's a Quarter Beast that shows a cat alike behavior. In the prologue, the Main Character finds her alone training martial arts day and night at an abandoned dojo, when she is "rescued" and invited to the guild, she enters in shock and recognizes it immediately, showing that something traumatic for her happened there. She also recognizes the Guild Member Lucy, where both, treat each other as inseparable friends. Luna shows most of the time a defensive behavior, as shown in many of her events. She got a strong protective feeling for her friends, to the point she told to the MC that she trained for years and years just to be able to protect the ones she care the most, being Lucy the most (and maybe only) remarkable one. Her Skills resemble those of a ninja and a cat, she got high speed, superhuman perception, and lethal attacks. She is able to withstand high falls and jump high distances. She absolutely hates the water, so much that she can be menaced with just a spray.
