Rubette La Lette ルーベット・ラ・レェテ

Rubette La Lette is a princess from the kingdom of Eschallato, where Gokudou is also from. She'd much rather sword fight and have adventures, than wait for true love. She decides to accompany Gokudou on his quests. Granny bestows her with a magic bow and arrow, which she uses frequently.
