Koharu is a digital character Stella befriended online; she’s a shy bunny girl with an awkward demeanour but is always polite and courteous to those she meets. Although Stella believed Koharu to be merely another online user in reality Koharu is actually a rouge Avatar that is searching for her player after she just stopped logging-in one day, she was just about to give up the search when she met Stella who befriended her and promised to help her find her missing player.
