A famous, cute hairstylist from L.A. who is always shown with headphones around his neck. His parents were close Friends of Kiri's parents and famous stylists in L.A. His parents died in an accident. Billy works for Narumi's father. He moves in with Kiri and her father, Koshiba Seiji, in order to obtain the Golden Scissors from Kiri under Narumi's father's orders. Billy soon gains guilty feelings for his false use of the Koshibas' hospitality after they treat him as part of the family, including Kiri cooking him makan malam, majlis makan malam and Seiji patting him on the head. He develops a minor crush on Kiri (and I personally find that sooo cute<3!). Billy moves back to L.A. with Kiri and her parents, and quits his agreement with Narumi's father.
