Haruhara Haruko (ハルハラ・ハル子), 19 (or so she claims), is an energetic, spontaneous pink-haired girl from outer-space and investigator for the Galactic Space Patrol Brotherhood/Stellar Fraternity. Mamimi observes that she looks at least twenty years old but, considering that she is of an unknown alien species, neither Mamimi nor the viewer has a relevant frame of reference. She rides a yellow Piaggio Vespa (and is also known as The Wasp Woman, a pun on the word Vespa, which means wasp) and wields a blue left-handed Rickenbacker bass guitar model 4003 (similar to the 4001 used by Sir Paul McCartney, whom she mentions in Episode 5),with a pull-cord motor on the back, as a bizarre weapon of sorts. She leaves it for a more powerful double-necked guitar (a fusion of the Gibson Flying V, drawn from Naota's N.O. channel, and the 1961 Gibson EB-0, from Atomsk's, that Naota creates while harnessing Atomsk's power) when she departs from Earth in Episode 6. She becomes the Nandaba household's maid and plays on a rival team of the Mabase Martians seemingly for extra money, but in fact to knock a satellite out of Earth's orbit with the baseballs she hits. She has also apparently had past relations with Amarao, most likely similar to her relationship with Naota. This mysterious character is the catalyst for FLCL's entire plot. She is called Haruha Raharu (ハルハ・ラハル) by Amarao; this may be another alias, however.
