Big Brother is a Prince!.Kirimi Nekozawa, a young girl, comes to Ouran Academy searching for her older brother, Umehito Nekozawa. She finds and labels the Host Club a "reverse harem" filled with "debauchery," terms the Hosts find startling, given her age. When Kirimi sees Tamaki's blond hair, she mistakes him for Umehito. Kuretake and Kadomatsu, two Nekozawa family servants, arrive to retrieve her, revealing that Kirimi is afraid of the dark while Umehito is afraid of the light. Umehito enters, but with his black cloak, black wig and Beelzenef cat puppet, he frightens Kirimi, causing Umehito to leave, dejected. Afterwards, Tamaki and Renge coach Nekozawa into becoming the princely figure who will save Kirimi from the monster in her house who, in actuality, is Nekozawa wearing his dark clothes. Tamaki and Renge convince him to give up his cloak and wig, saying his photophobia is psychological. This leads to him saving Kirimi from a large unfriendly cat and proves his bravery. Despite temporarily overcoming his photophobia, Umehito succumbs to his skin's sensitivity to sunlight and collapses. The Host Club believes they were unsuccessful when, in reality, the Nekozawa siblings reforge their bond.
