Yasuyuki (やすゆき ) is a minor antagonist featured in Shodai Nekketsu Kōha Kunio-kun. He is a member of the Osaka Union and is a subordinate of Wada.
Background[]
Yasuyuki first appears with some other members of the Osaka Union outside of the Hanshin Tigers Archive in Koshien. He listens in on Masaki Yanagisawa and Kunio's conversation and then confronts the latter after he exits the building. Yasuyuki mentions that the Nekketsu High School students are likely being attacked by Yoshihiro. Kunio questions why Yoshihiro would attack them, to which Yasuyuki reveals that Yoshihiro is the second leader of the Union and wishes to get rid of the Nekketsu students. Yasuyuki and the others then attempt to fight Kunio, though they are defeated.
Later in Namba, Yasuyuki appears once again alongside other Union members in a rematch fight.
