If the ears haven’t given it away, Multi is a robot – a maid robot, specifically, from Kurusugawa Electronics. She is a prototype, and arrives at Akari and Hiroyuki’s school for a two-week stay for final testing.   Multi is a bit clumsy but has a big heart, and is endlessly cheerful and considerate. She has a simple, childlike personality, and loves to clean because it makes others happy. As a maid, she can’t really compare to Serio; but as a “human being,” Multi is an unqualified success.   (Source: RightStuf)
