Ai Hayakawa Ai Hayakawa is one of the main characters in " " . She is one of a set of twins , with her brother Yu Hayakawa being the other . When they were twelve years old , their parents , the geologists Joe and Marie left their island home of Sadoshima in Japan for their second trip to the Wonderland . Their parents did not return after a long time , which prompted the twins to go look for them . Of the two twins , she is usually the more practical , often taking charge of the situation , even in the presence of her elders , such as Lisa . She also has a very short temper , as shown when certain things annoy her and she flies into a blind rage over small things , such as Poshepoke ' s mischief or any other Wonderland creature ' s peculiar behavior . She is also very untrusting , initially treating Lisa , Kaze , Fungo , Chocoimo and Chocobaba with hostility , though she quickly warms up to people . Story . Twelve years before the main setting of " Final Fantasy Unlimited " , she and Yu were a part of Chaos , but split from the main body for unknown reasons . When the twins where found by the couple Joe and Marie Hayakawa , who had recently lost an unborn child , they were still in the form of babies , and were thus taken in by the couple . The twins were then raised by Joe and Marie and brought up to believe that they were human and that their emotional parents were their biological parents . Not much is revealed about her childhood , but when her parents left for Wonderland a second time and failed to return , she was the one that took care of feeding herself and her brother , albeit mainly instant food . After her parents were absent for a much longer stretch then originally anticipated , it was she that suggested they venture into Wonderland to look for them and convinced her brother to agree . After discovering the rumor of the Subway ' s arrival at a specific time at night , she and her brother packed and set off to Wonderland , meeting up with Lisa Pacifist shortly after boarding . Though she initially distrusts Lisa , she allows her to follow them , and quickly befriends her . At there first stop , Yu stumbles across a strange man bound by roots . After being chased by a large monster , which Lisa initially dispatches with her Kigen arts , which just furthers Ai distrust of her , the man returns and destroys the creature with a powerful gun , giving his name as Kaze . Once again , Ai initially distrusts the newcomer , and is annoyed when Yu insists on attempting to engage him in conversation . After leaving the town and making their way to their second stop , Ai is once more reminded of the difference when her bang is stolen , and she looses the thief . It is then she meets Fabula and obtains Poshepoke . After traveling with her twin , Lisa and Chobi for some time she eventually separates from them while within the Ocean Puzzle . It is then she meets Clear , a boy that embodies the soul of Omega , for whom she developed a crush on . They are separated soon after meeting , but she manages to retain a single glove he wore to keep his powers in check , which she becomes very possessive of . Soon after she , her brother , Kaze , Makenshi and Lisa are all captured by Earl Tyrant . It is now that she learns of her parents ' enslavement and her origins as a part of Chaos . Clear is also in the Earl ' s captivity , and he is compressed into crystal form before her . Poshepocket . Poshepocket is a small sharp toothed creature that functions as a handbag fashion wise , and a means for the use of hammerspace in terms of the series ' s mechanics .
