(Killua was fighting a Octopus type chimera ant called Ikalogo and he let Ikalogo go because they wanted to be friends and stuff and but a small fish-like chimera ant called Coburn attached a badge to killua’s back and he went to find a exit but he heard a digital sound in his head but he noticed a needlefish stabbed his hand and then in his stomach then he realized that he that the Ortho siblings ability involves darts and he kept getting attacked) (the ortho siblings power works by the younger sister creating a nen pin that connects the target to the older brothers dart game and they cannot deactivate the pin until the game is over but if the older brother missed the last turn,then the damage goes to the siblings)
