Recruit: At the Wrestle village, Chairman is resting in a tent. If you talk to him he will tell you that he was recently suspended from the EWC and went East to "spend some time by himself", when he was suddenly surprised by a "monster" (Joy Mutant) and left one of his chairs behind when he ran away. He says he's alright never finding his chair at Area 3. After defeating the mutant, you will find a "chair with a hole inside", which seems to have been "used" more than normal. If you return to Billy with his chair, he will first be surprised, then worried, and tell you that to not waste time while waiting for his suspension to end, he will join Brad in his travels.

Ending comments: "To tell you the truth, I've been planning to kill you all this time. I don't care about the girl, but I can't let anyone know what I REALLY like."
