Also known as XP Home-kun, Homeo is portrayed as a gender-confused boy who looks akin to his sister Homeko. He is typically shown wearing a key shaped hair-clip and an XP shaped necktie. Homeo is a transvestite and often cosplays as female characters, most commonly Kanaria from Rozen Maiden. He fancies 98-tan, and there have been numerous occasions when they have nearly gotten together.
Homeo is one of the more complicated characters in Troubled Windows, for a number of reasons. First off, he is one of the more sexually complicated characters. He desires to become a woman, but only to have a relationship with his sister, Homeko. He often cosplays as female characters, which appear to excite Homeko. Many zany, and often ecchi situations ensue. 98-tan (Hacchan) also loves Homeo, who returns her love to a degree. Hacchan often assumes a domination role over Homeo, with very unusual results. Their relationship is much to the chagrin of 98SE-tan (Secchan), who also likes Homeo. Secchan's preoccupation with castrating him with a bottle opener, however, complicates this situation.
Homeo is not truly gay in that he bears no liking of men, but desires to be a woman. This unusual sexual trait leads to some situations, many involving the love square between Hacchan, Secchan, Homeo, and Homeko.
