In the distant future, mankind has long left the Earth and spread all over the Milky Way. Humans settled down on different planets, sometimes coming into contact with other races, and established a connection between them. The player is a nameless young man who was a mere child when he survived a spaceship crash and had to seek shelter on a new planet. Now he is sixteen, and his parents plan to send him to attend schooling on the planet Terra. That is when his adventure begins!

Blue Almanac is a sci-fi Japanese-style RPG. The player's party encounters random enemies and fights them in turn-based combat. The combat is viewed from a side-scrolling perspective and both the player's and enemies' attacks are animated.

The game takes place over multiple planets and has an epic space story (similar to Phantasy Star II) that emphasizes substance over style with its minimalist graphics.

This game was officially released worldwide, in English, on June 22, 2011 under the name Star Odyssey. It was produced and published by North American company Super Fighter Team in cooperation with Starfish-SD Inc.
