He Kui has crossed over into the world of Gundam SEED, but in this world where talent and background determine everything, as an ordinary Coordinator in the military academy, his future can be described as shrouded in dark clouds. However, there is still hope, as he has received a golden finger, although... it is somewhat peculiar.
