each miniature version with their own names and slightly different personalities (Rinaji, Rinayo, Rinacchi, Rinamu, Rinazo and Rinako). In both the anime and ONA, Rinako is killed by a red bug in the first episode, and Rinazo is presumed dead before the start of the anime, but the other Rinas are not affected by these losses and the series continues with the four remaining Rinas. Rina has a very childlike, curious and playful personality. Her specialty power is taste, with the Rinas always scouring for various types of scrap metal to eat and satisfy their large appetites. Eating scrap metal makes the Rinas very strong despite their small size, and they can also manipulate small balls on the ends of their maid dresses to act as weapons or security scouts. They were both apprehensive and curious about Wakaba when he first appeared, wanting to eat him to see how their bodies would be affected. However they quickly warm up to his polite and equally curious personality, though they continue to make fun of his clumsiness and aloofness throughout the series. The Rinas are also aware that Rin and Wakaba have feelings for each other, but they do not mention this until near the end of the series. The anime Rina is largely the same as her ONA counterpart, with the only differences being her height and outfit design. In the ONA, Rina does not look so much like a child and is actually the same height as Rin, though she maintains her childlike personality. Her outfit in the ONA does not have the detachable parts used in the anime, instead having green electricity-powered designs on the skirt. She also wears green and grey striped socks in the ONA, but these are absent in the anime. One of the older sisters presumed to be dead prior to the start of the series, however Wakaba finds her alive and well on Island 6. She tells Wakaba that she left the sisters to investigate the world and try to figure out the relation between the kemurikusa and akamushi. Riku wears a hooded black dress, a red scarf, and ties her short magenta hair into pigtails. She was known to be the most clumsy and careless among the six sisters, so much that the sisters use her as a reference for Wakaba's clumsiness. Regardless, she is also very brave and adventurous, excavating new areas
