Ringetsu, the original by Selen, featuring the four main heroines shown here. Then Selen did a remake called Shin Ringetsu feautring only the true love routes for the four main heroines and also a new 'what if' scenario featuring a fifth heroine who had actually died in the original, beginning the plot. Inbetween the original and remake was a fan-disc game called Tsuma-Mix, which was a collection of after-stories from Selen games, one of which was from Ringetsu (Shino's story, the only girl shown twice here, though they don't make any comment about which route is canon.)
They also did two hentai series, one based on the original Ringetsu, and the second based on Shin Ringetsu with various uality of animation.
Cool story: Ringetsu and Shin Ringetsu were both animated by Keitarou Kawagishi, the artist behind the Majikoi series.djwhqd
