Rondo

Protagonists sees a mysterious girl in his dreams who reminds him one of the girls in the class. This is a story of his relations with several class girls over a few days.

Game was interesting enough for me to see it through the end. The coolest part is confrontation between his childhood friend Fujiwara (descendant from Fujiwara clan) and mysterious girl Hojo Miyuki (descendant from Hojo clan). And the protagonist turns out to be descendant of Yoshimoto. On top of historic parallels there is enough mystics involved to keep interest all the time.
