Thanks for visiting NCHANS STUDIO ( This website is managed by Challengia and serves as the official source of informations regarding the series “NCHANS”. As it contain suggestive materials (erotism, partial nudity), this website is not suitable for everyone. Other sources are third part websites and social medias.

“NCHANS” refers to both the series and the main characters. The NChans are a group of characters created in 2013 by Challengia with the help of artists Acetea-san (2011) and Gumwad201 (2013-2014). Originally the NChans were the mascots of the Challengia’s 2011 website called “NChallenge” at that time, the concept was to have hostesses guiding visitors throught the website and social networks. In 2015 the choice was made to develop contents around the NChans and make a series with video games, mobile games, mobile apps and other forms of representation.

NChans characters, logos and softwares belong to Challengia.
