Nanboku

The story takes place in Ogikubo, which is the name of the specially designated area in space in the Milky Way where Earthlings and aliens can live together. Luluco is a female middle school student who lives with her father, and no matter where she is, Luluco is a common, "super normal" girl. As she is living her normal life, one day the mysterious transfer student ΑΩ Nova abruptly appears before her. That meeting will change Luluco's fate.

The day after a red shooting star fell to Earth, a man wakes up to find himself in an apartment with no memory of what happened up until that moment. Could he be "Char"? Or is he just someone who happens to look like him? One mystery seems to lead to another! A hillarious spinoff to Neo Gundam! (Via ComicWalker)
