Hotaru Futaba (voiced by Suzie Yeung in English, Manaka Iwami in Japanese)

A young girl searching far and wide for her older brother, who disappeared when her mother passed away. As luck would have it she would one day run into someone who looked very much like him, though he denied all knowledge of the matter. But that was then, this is now, and Hotaru still hasn't given up: determined to fight the mysterious stranger again and convey her true feelings, she sets off into the unknown once more.
