The story opens on a construction site for a new school. A back hoe is having problems excavating the area because of a large bronze colored stone. A worker told to investigate it finds a rather curious monument with a removable plate. The two supervisors decide that they do not want to delay their schedule for an investigation, so they tell the worker to throw away the plate. As he does so, the worker wonders if that is a such a good idea and he ends up putting the plate into his pocket. Suddenly the world bifurcates around that one decision. Twenty-two years later, Kazuki falls asleep on his keyboard while updating his web site/bulletin board. He rushes out to school as he is late. On his way to school we hear two girls comment about him. \"Him? He is the one?\" \"Looks like it...\" Suddenly shadows flash overhead and an explosion occurs right behind him. Although Kazuki flinches, the debris seems to pass right through him, as if it were not really there. In the distance two giant mecha fight. The two girls giggle. Where there should be a crater from the explosion, there is just the two girls being amused at the infamous boy who has sudden spasms and fits and claims to have seen giant robots fighting. It seems that only Kazuki can see these battles so he has taken to documenting them on a web site calling it a story. He has even named all the robots. Later that day, the school idol Sanada Mitsuki follows Kazuki and tries to get him to tell her about the mecha because she says she knows something about what he is seeing. This leads Kazuki to Mitsuki\'s house where he gets to meet her enthusiastic mad-scientist father, who explains that Kazuki is seeing a parallel world. It is not enough to say that, though, and the father is intent on sending Kazuki to this parallel world. (Credit to carnage.fanfic.org) (Credit to Duragon who posted it first.)
