Most ghosts are highly otaku-oriented; hence, even if the user is a native Japanese speaker, he or she probably does not fully understand what they are talking about, unless they are an otaku to a significant degree. Not always, but in many cases, they are chatting to each other assuming the user (that is, the reader) is very familiar with the games released by Leaf and by Key. Also note that, in many cases, Unyū does not speak standard Japanese, but speaks the Osaka dialect (as often as not it is a fake Osaka dialect made up by a non-Osaka dialect speaker). Ukagaka is, in a narrow sense, a platform on which any standard-compliant ghost runs. There are a few Ukagaka-compatible platforms, such as SSP (Sakura Script Player) and CROW. Many users prefer SSP to the original Ukagaka, whose development has been stalled. Ukagaka, or its compatible platform, usually comes with its default ghost. It is possible and usual to have more than one ghost on the same platform, when the ghosts are switchable (that is, the girl the user selected from the menu appears on the user's desktop). An additional ghost, including its shell, is usually provided as a single (Nanika Archive) file, which the user can easily install by dragging and dropping onto the running shell. Shiori Basically, each ghost has its own personality, talking differently about different topics. This means that each ghost has its own shiori (a conversation-generating module). However, it is not easy to implement a shiori from scratch. Usually, middleware is used to make it easy to create a new ghost. KAWARI is open-source software used frequently for this purpose. Internationalization Although it is not well documented, it is easy to create a ghost that speaks a language other than Japanese. Also, it is possible to change the menu language of SSP into English, but since SSP is just a platform, changing the menu language does not change the language the ghost speaks.
