Yuya Fungami (噴上 裕也, Fungami Yūya) is a minor character in Diamond Is Unbreakable. He is featured as an antagonist in Highway Star, and as an ally in Enigma Boy.
Yuya is a motorcycle gang member who was made into a Stand User by Yoshihiro Kira and prompted into attacking the Joestar Group. Selfishly attacking Rohan and Josuke in a high-speed road chase, Yuya later assists Josuke in the fight against Terunosuke.
Yuya is a young man of average height and slim to fit build. He has a short undercut and his chin is tattooed with a stylized "H☆S".
Like Josuke, Okuyasu, and Mikitaka, Yuya wears a dark, modified school uniform. He wears a long, bouffant, light tie with the words "Highway" and "Speed King".
Introduced as he attacks Josuke from afar, flanked by three female admirers, Yuya comes across as vain, selfish, and cowardly.
However, he shows a sense of loyalty, bravery and good skills of deduction when joining the battle against Terunosuke Miyamoto. He is protective towards his three admirers, who, in turn, are very close to him.
Terunosuke reveals that when afraid, Yuya tends to touch his chin.
Yuya's mainly automatic Stand is Highway Star, which tracks targets at a speed of 60 km/h, but reappears nearby the target if they're too far away, in order to efficiently absorb their vitality.
Yuya also has a powerful sense of smell.
Yuya Fungami is a motorcycle racer who got drunk and suffered an accident. In it, he had his spine damaged and almost all of his bones broken. While in the hospital, he was pierced by Yoshihiro Kira with the Bow and Arrow.
Wanting to heal faster, Yuya used his Stand to absorb energy from people. With his three admirers taking care of him in the hospital, he used his Stand to absorb Rohan Kishibe's energy.
Yuya tried to do the same to Josuke, but his location was found by Koichi, and Yuya was confronted by Josuke. Josuke healed him so he could be heavily injured again by Crazy Diamond. He was forced to stay in the hospital for a few more months under the threat of being beat up again if he tried to use his Stand.
Yuya appears again when Koichi is kidnapped by Terunosuke Miyamoto. Josuke asks him to find Koichi with his heightened sense of smell, but Yuya warns him that this is the only thing he will do, not wanting to be an enemy of Yoshihiro. Josuke agrees, and they both end up finding Tomoko Higashikata shortly before Josuke is turned into a paper by Enigma.
Inspired by Josuke´s bravery in his attempt to save Koichi, Yuya thinks about how he would do the same for his admirers and saves Josuke and Koichi, after which he is turned into a paper by Terunosuke. Koichi and Josuke save Yuya in return when Terunosuke threatens to tear the paper in which he is imprisoned. Yuya is last seen saying goodbye to Reimi Sugimoto at the end of the part.
In the Morioh City stage, Rohan's bike from the Highway Star chase is present. The player is able to freely control the bike around the stage, and attack enemies with it.
