Oga uses 30cc of Super Milk Time to supposedly defeat Vabam and Schethalim. then explains the rules for the room their in. Rule #1 - Acts of violence are forbidden in this room. The matches will be decided by games, not violence. If you break this provision, the damage that is inflicted, will be returned to the rule breaker in kind. Oga gets all the damage that should have been inflicted to Vabam and Schethalim. Quetzalcoatl makes Oga play Sudoku to pass. When Toujou shows up he is surprised he beat both the Pillar Barons, Toujou then admits that he let one get away. After Himekawa helps Oga beat Schethalim in Sudoku, he is surprised yet again.
