3x20 - Welcome to Demon School! Iruma-kun

Iruma goes over to Lead's house after getting a brand new gaming console. While they're playing games, Lead's older sister Shakky suddenly bursts into Lead's room, and she seems to be in a really bad mood... Ameri and Iruma end up making homemade cookies together. But apparently, neither one of them has ever cooked something properly in their lives. They are an absolute mess in the kitchen and even Opera seems to have some trouble dealing with them...
