Hotaru is a loner. She has a hard time making and keeping friends. She prefers to be alone, often times studying the planet Saturn. She likes to pretend that she is the princess of said planet. She wants to be able to make friends, but she has a hard time talking to others. The other Hazard has to be willing to go the extra mile and be willing to spend a lot of time with her. Once she gets to know you however, she is a chatterbox. You wouldn't even know that she's the same Hazard as her shy personality.
