Arisu is one of non-student characters of the year 2007 in the Dash spin-off, she is a respected street fighter with a cult following and wants to get them interested into retro games. She seems to be a very hot headed person, she is first seen pretty chill but get's ticked off very easliy to the point we're she get's physical and let's it out on other or herself (I don't know how ether). She also very clingily on the people she likes, as seen with Yamai, to the point that she even threated Hidaka that she would steal his virginity in order to keep him around. She also has a fond of retro games and arcades, and despite them not being as popular as back then, she still wants to show her cult following and others the beauty of them.
