Kikumaru
A yakuza thug working for Xavier to sell the weapons his flock produces. Him and Suzukichi come after Yuri, and, in despite of Fuu’s alleged kendo skillz, carry her off back to Xavier. He’s next seen negotiating in an illegal weapons deal with Kuroihara, while Jin is eavesdropping on the porch outside the window, hearing the whole thing go down. When Momo shows up with Fuu’s letter, Jin and Mugen track him down on the way back from his arms deal and force him to lead them to the grotto where Fuu is being held.
After Mugen and Jin barge in, he runs up to tell his boss Xavier that the gig is over, and is then shot point-blank by him.
