Final Approach (Φなる·あぷろーち) is a 2004 visual novel that has been adapted into an anime designed by Aoi Nishimata in visual novels, Yukiko Ibe in anime adaption. The title uses the Greek letter Φ (phi) to represent to the “fi” (ふぁい) in the Japanese transliteration of the English word “final”. The series of half-length episodes aired in Japan in October 2004 (back-to-back with W~Wish, a separate series), with the last episode ending a few months later.
Ever since their parents died a few years ago, Ryo and his sister Akane have been living alone together. Despite their difficult situation, they are still living reasonably happy and normal lives. However, everything is about to be flipped upside-down due to a secret government project. Due to increasingly low birth rates in Japan, the Japanese government is testing a program in which two young people are forced to marry. Ryo wants no part of it, but he is given little choice in the matter; his new fiancée, Shizuka, comes to his home late one night with several dozen government issued bodyguards, who are there to ensure the success of the new couple. Unlike Ryo, Shizuka couldn’t be more willing to go along with this new program, and eagerly goes about her wifely duties, despite his objections. With meddling friends, pushy bodyguards, and an overenthusiastic new fiancée, Ryo’s life has taken a turn in a direction the young man certainly didn’t expect.
