A transvestite who first appears in Round II, where he poses as a woman named Hitomi (Hitomi is his friend for whom he substitutes as player No. 3). Sly and calculating and also a 5th degree black belt, Fukunaga is a skilled manipulator whose greatest weakness appears to be his desire for money and his bad temper. He greatly hinders Nao and Akiyama during Round II and the Revival Round, but has never been able to outwit Akiyama. However, Fukunaga cooperates with them well during Round III and even when he finishes the round debt-free, he chooses to continue in the tournament. During Revival Round II, he disguises himself as a woman again. To avoid revealing his skills during the mock stimulation, he sends Nao in his place, matching Solario's expectations. Though Fukunaga seems fond of Nao in his own way, he doesn't think of her as competent.
