I don't really know what to say about this manga. Amnesia in manga is almost always taken advantage as a trope. There's been a few manga where it's been done very well, but, unfortunately, this isn't one of them. The story is silly and ineffective. The scan itself has some glaring errors, proof that even the translators assigned to the project couldn't muster up the energy to care about it. There's a reason this one-shot stayed a one-shot.
