Modern youth Lin Fan unexpectedly transmigrates to the world of *Mobile Suit Gundam 00*, landing on a space colony satellite at the beginning of the story. He acquires the mysterious "Gundam SEED System," which not only allows him to summon all pilots from the CE era (including those from the theatrical versions) but also provides a complete blueprint library for all mobile suits and warships, including mass-produced models and various types of warships. To avoid becoming a pawn of various factions, Lin Fan chooses to establish the independent mercenary group "ZAFT." Leveraging his advanced knowledge and SEED technology, he rises to prominence when Celestial Being intervenes in the world, navigating between three major factions (Human Reform League, AEU, Union), Celestial Being, Ribbons, and subsequent alien threats. He uses SEED technology to rewrite the fate of the 00 world and explore the true meaning of war and peace.
