Kizuna told Elena that Hibiki was going to be her personal guide for the duration of this trip. After that Kizuna also told Elena about a secret of Hibiki that almost no one knew about.
Hibiki was a fearsome assassin so even the people who knew her had the impression that she was a cold and merciless killer who cares about nothing but her job. But that could not be further from the truth.
Hibiki was an excellent assassin but the virtue of diligence was absent in her. She was super lazy and most of the time completed her missions at the very last second.
She was also not without a hobby. Her hobby was travelling. Whenever there was a task that needed the assassin needed to go out of the Inazuyan Archipelago, Hibiki always stepped forward to take that task.
Her colleagues had always thought that Hibiki was impressive for taking the dangerous "away jobs" but the only reason why she always took them was because it allowed her to travel for free.
