HMX-12 Multi (マルチ Maruchi ) is a robot created by Kurusugawa Electronics and arguably one of the most iconic characters in To Heart.
Multi is a cheerful and high spirited robot girl who desires to act just like a human. She was sent to Fujita's school in order to achieve this.
Multi has short green hair and emerald green eyes. Her large robotic 'ears' enable her to be distinguished as a robot. She wears the school uniform most of the time.
