The Debauchery Tea Party (放蕩者の茶会 Houtou Mono no Chakai, lit. Tea Party of Libertine) was a non-guild group of players in Elder Tale. It was present for two years before they disbanded, but its name is famous even now after the Catastrophe. Aside from the nine members of the Tea Party that were trapped in the Elder Tale world due to the Catastrophe, the rest of the twenty-seven members come from the Mamare Anthology, a fan book, and were adopted into canon by Mamare.
