Seeing as though her gaze never once left his sight, the spiky haired arrancar slightly turned his face. He wasn’t used to being looked at for so long; she spoke and he listened quietly until she finished. “Of course, although I do have to warn you; I don’t believe it will be allowed to have a hollow around the place. Most barbarians may try to eat her, so I suggest that when you choose your master you tell them about your sister or you just keep your sister a secret.” he said in a calm, but emotionless voice.
It would have been a tragedy for her to have invited her sister in her room just to have someone go and kill her. Hiei was born an arrancar and therefor only sought to kill when he was hungry and not for the fun of it. But lately he was pressured to do so to get stronger, although he wouldn’t eat someone’s sister. He watched for her reaction with a stern face never once flinching.
