Hotaru was born on Koristar, planet where there is winter all the time. She knew about AKB0048 since young age since her parents were always listening to their songs in secret, because Koristar is under entertainment ban. When Hotaru was 10 they got chance to move to Atamistar so they decided to go there.
Hotaru's parents were always big AKB fans and often listen to their songs even though Koristar was under entertainment ban. Hotaru loved them too and when she was young girl she already decided she'll one day become their member too. She often went to forest and listened to their songs. One day when she was 7 and was again doing that, Hikami Yumeko heared her and she invited her to join her. Hotaru told Yumeko about AKB and after that they were together everyday. When Hotaru's family decided to move to Atamistar she and Yumeko promised to each other that they'll meet again when they'll both become members of AKB0048
