Haruna Miyashita is a secondary character in the anime Ren Arisugawa Is Actually a Girl. She is one half of the idol group Haru x Momo, performing alongside her partner Momoka Hiiragi. In contrast to Momoka's pure and sweet image, Haruna is characterized as a cool and composed girl who consistently looks out for her partner. Her role in the story involves navigating the entertainment industry as part of this rising idol duo, particularly in contexts where they interact with the main character, the popular male celebrity Ren Arisugawa. For instance, Momoka is noted to be excited about co-starring in a drama with Ren, a situation in which Haruna's protective and level-headed nature likely comes into play as she supports her partner. Haruna Miyashita is voiced by the Japanese voice actress Hotaru Hanakage.
