Trivia

 * Every member of the dormitory is shown to be wearing a red-stained white rose. This references the part of Alice in Wonderland where the Queen's gardeners plant white roses by mistake and attempt to paint them red so she doesn't notice. The Queen does and gleefully orders for them to be beheaded.
 * Heartslabyul's animals are hedgehogs and flamingos which they take care of well so that when they play croquet they have a close bond with the animal helping them score more than the other player.
 * Based on the Twisted Wonderland Manga Anthology, the students of Heartslabyul live under and obey the rules set by the Queen Of Hearts, no matter how odd the rule may seem.
 * All of the students in Heartslabyul are afraid of the Dorm Leader, Riddle who gives out strict punishments to those who break the rules set by the Queen of Hearts for the tiniest mistake made by any student.
 * It's a pun that there are 810 rules. "810" can be read in Japanese as ハート (haato, heart).
 * Beastsmen students can be include in the dormitory since Riddle mentions they had a cat beastman in their dorm.
 * It is confirmed in Episode Of Heartslabyul where several beastmen students appears as Heartslabyul dorm members.
