"Unless you tell me the truth, you will be punished unfairly. And then, not only will you be subject to your own detested punishment--but Usako, who cares for you, will hate her parents forever."

While her primary role is the protection of the Queen, Hotaru has always held a close friendship with Chibi-Usa. When she finds out about Seisui and Sailor Titan, rather than taking the distrustful stance of the rest of the Sailor Senshi, she seeks to find a way to help Seisui. Hotaru may sympathize with Seisui's deeply imbedded anger because of her own past as Mistress 9.
