Yugo Ogami (BLOODY ROAR)

Yūgo Ōgami is a young wolf zoanthrope on a quest to uncover the circumstances of his father's death. His father, Yūji Ōgami, was a mercenary said to have died in combat in a South American country. Yūgo also seeks the mercenary Gado, the sole survivor of Yūji's combat unit.[1] Yūgo and Gadou eventually meet in a secret Tyron Corporation laboratory, where Gado reveals that Yūji was a zoanthrope who fought against the Tyron Corporation's mind control experiments and conversion process. Yūgo then promises his father that he will destroy their enemies with the powers that he inherited from him.[2]
After the fall of Tylon, Yugo hides his Zoanthropy and takes up a career as a boxer. He is not truly alone, as he took under his wing a boy he found during the destruction of Tylon. The boy had no memories and nobody to take care of him, so Yugo took it upon himself to adopt him as his brother and named him Kenji. One day, five years after the incident with Tylon, Kenji is mysteriously abducted by a strange person. He assumes this is a sign that Tylon might be resurfacing and decides to fight back and rescue his younger brother.
Yugo becomes the leader of an NGO (Non-Government Organization) called the W.O.C.(World of Co-Existence). Their goal is to build a bright future for both humans and Zoanthropes alike. But a mark known as the 'XGC' appears on his body. The 'XGC' will eventually end his life and end the lives of others who are afflicted if he doesn't find out how to stop it. He sets out to uncover the truth.
A representative of the Zoanthrope tournament visits Yugo. Prior to his visit, a group of men and a woman had attacked Yugo as part of a test to show the representative his legendary skills. Yugo had worked out for himself who they were working for. The man gives him an invitation to the tournament. Yugo accepts, wanting to learn more of the 'bad' activities going on behind the scenes.
Yugo has been racking his brains over the violence occurring. While out investigating the incidents he heard rumors of a 'Black Shadow'. Also, that the name of this 'Black Shadow' was Nagi. This name he'd heard before. He was sure she had been a victim during the incident with the XGC a year before and was still in a hospital somewhere. In order to learn the truth, Yugo sets out on a journey.
