Futakoi [JP]

Futakoi is a light novel, visual novel and anime series created by Hina Futaba and Mutsumi Sasaki. The anime series aired in Japan in 2004. It replaced Sister Princess as Dengeki G's Magazine premier flagship title.

Futakoi is a conversation game that features over six pairs of twins. The objective is to bond with pretty young twins via what the developer calls a "twin view mode." Players use a multiple choice system to have conversations with the girls and try to keep a perfect balance at all times. If "twin view mode" isn't enough novelty for you, consider that Futakoi also introduces the "love junction system" -- which is just a fancy term for branching storylines, of course.
