Background

Before the acclaimed Narcissu anthology, stage-nana was a humble doujin circle which made five derivative novel games: Summer Album based on White Novel; Eien based on One ~Kagayaku Kisetsu e~; and Duette, Duette 2, and Duette [a] based on Kanon and Air.

Stage-nana later spawned the company NekoNekoSoft, and both still are going strong along with their founder, Kataoka Tomo.
