You tried to negotiate with Higuruma about giving you his 100 points to create a rule for the Culling Game, but he refused. You got frustrated and decided to prepare to fight Higuruma. "Have you ever killed someone who's pissed you off? It feels better than you'd think." Higuruma would say that earlier to then activate his Domain Expansion. The area around you is similar to a courtroom with only two stands, in one of them would be Higuruma and in the other would be you. You will see a Shikigami behind Higuruma pretending to be a judge.
