Appears before the Workshop Moderators telling them they could earn a lot of money to complete his research by using a bet system and not have to worry about if you know the director, as he will take care of everything. Then he tells his subordinates that soon Jyu Viole Grace will be in his hands.

His silhouette is later seen amongst the Slayers and Elders in FUG who oppose the young Slayer candidate being granted Enryu's Thorn to be used as a weapon.
