Miharu Amakase is the childhood friend of Nemu Asakura and Junichi Asakura, bonding closely with them after Sakura Yoshino left, despite being one year younger. A significant incident defines her past: she fell from a tree trying to rescue a kitten, resulting in a coma. During this time, her father created an android replica to take her place. This android matched Miharu's physical characteristics exactly—153 cm tall, weighing 39 kg, with measurements of 78-54-83—and mirrored her core personality: energetic, carefree, occasionally clumsy, and possessing a notable love for bananas. The android Miharu forged a strong bond with Junichi while attending junior high. It required periodic maintenance, including winding via a key in its back, and used bananas and solar energy as power sources. Its behavior replicated the real Miharu's enthusiastic and sometimes overly earnest nature, often leading to circuit overloads requiring Junichi's intervention. The android ceased functioning upon reaching its operational lifespan, coinciding with the real Miharu awakening from her coma and reuniting with her friends. After recovery, the real Miharu resumed life, exhibiting the same energetic personality, her adoration for Nemu (often likened to a puppy's devotion), and fondness for bananas. Returning to school, she took on responsibilities like acting as Junichi's "waker" following Nemu's departure, though she occasionally displayed naivety about human biological processes. She maintained a habit of frequenting the school clinic for health monitoring. In *D.C.I.F.*, Miharu's role continues post-recovery. The extent of her awareness regarding the android's experiences remains ambiguous, though her personality and mannerisms remain consistent with her pre-coma self. Her background as both a human and an android's model underscores themes of identity and continuity within her character arc.
