Yukio

After Hideki shoots a drug in Logan to slow his healing factor, he loses the fight and Shingen's henchmen take his body to a railroad track. Asano follows the men to save Logan only to see he was gone. Logan awakes in an apartment treated by an assassin named Yukio. Logan goes to Asano's office to give him evidence, but finds him stabbed in the heart with a thin blade. The police arrive on the scene to see Logan and Yukio standing near the body of Asano. The duo escape and slaughter Yakuza trying to ambush them. Outside, a mutant name Kikyo Mikage, who has similar powers to Wolverine's, appears on the roof ready to fight him.
