What if an ordinary boarding school got nearly invaded by an alien robot? And that the main characters who are human students defeat the cyborg by hitting her at the head, then accidentally teleported two elves from another dimensions. NOW, how the hell can the elves get back? The cyborg has completely forgotten its memory data of being an earth invader to a colorful, happy and normal girl. This is the newer version. i had delated the old one because i relies it`s boring to look at.
