Hikawa is a human designated as a "Collector" or "Gatherer"—individuals granted supernatural abilities through coins bestowed by an alien entity. Before gaining these powers, she competed as a track runner, an athletic background enhancing her physical prowess. Her motivation for using a coin was to wish for heightened speed to dominate in sports, resulting in monstrous transformations to her arms and legs. Though achieving extreme velocity, she resents these physical alterations. Her endurance exceeds normal limits, further amplified by her modified physique. She demonstrates formidable strength, evidenced by effortlessly kicking another character with enough force to fracture a wall—earning a "wall" level rating in both strength and durability. Her speed reaches peak human levels, aligning with her track history and wish enhancement. Intelligence registers as average or slightly above average for a high school student. Personality-wise, she exhibits selfishness, prioritizing personal ambition over the consequences of her wish.
